Debian Programming :: Cross Compiling With Qt
Dec 11, 2014
I am trying to cross-compile my Qt application for armhf on Jessie, so what I did was install qt5-default:armhf, but when I tried running qmake I found out that it contains also an armhf version of qmake so I was not able to run it.Then I installed the amd64 version to have at least a runnable version of qmake, but it was only to find out that qmake contains only hardcoded paths, so I could not use it for the armhf libraries, well I could but I had to run qmake (amd64 version) and afterwards open the makefile and change all paths from amd64 to armhf.
But as this is not so convenient I was wondering if there is a normal way to do this, I know you can compile the source yourself but I had quite a lot of problems with dependencies there. Is it possible with the standard repository binaries or should I just go back to compiling the source myself? Maybe I can compile only the building tools without building all the libraries I already got from the repository.

I just finished building a cross-compiler for i386-elf. But when I try to use it, the terminal gives me this error:
Code: Select all/home/isaac/Cross-compiler/lib/gcc/i386-elf/4.8.2/../../../../i386-elf/bin/ld: cannot find crt0.o: No such file or directory

I have an odd thing. And thats the following:
I entered: gcc raw.c -m32 -g -static -o raw
And I got:
I installed all bin32 libs I am on a x64 system.

I have written a program that I would like to cross compile for x86 and x86_64 architectures. I have tried google and the search function here to no success, most information I find is too specific (instructions for a specific program), or dealing with cross compiling for windows on linux.Does anyone know of a tutorial dealing with straight making a 32 bit binary on a 64 bit processor (both are intel)?

I wanted to know how can I cross compile SMS SERVER TOOL for an embedded computer and make just one binary file for it or how can I change all of its default files places like its demon and object file and gather all of them to one directory to execute and use and run.let me explain it better for you : I have an embedded computer with Linux OS that its file system is read only and I can not add any file to /usr /lib and ..... and I can just mount a SD memory card to it and copy all of my programs to it and run them from there as you understand I have two choices to choose, first make one big binary file for each program that I am doing it now and it is not a suitable solution and the second is finding the way to change default place of shared object file of my program.now you tell me what can I do to solving this problem.

I try to cross compile udev-160 for arm.I use the buildroot toolchain.I work on a PC i386 with the Debian system.I started by running "configure" script to generate the makefile:$./configure --host=arm-linux
but I obtain the following error :checking for acl_init in -lacl... no configure: error: libacl not found
I don't know how to install the libacl for ARM. I can't found the libacl when I configure the buildroot toolchain.

I'm trying to build some boot and kernel images for my WD Mybook world edition, which uses an arm processor on my x86_64 host box. Ultimately i'd like to install slackarm. Lilo doesn't work on arm so you have to compile your own kernel and have the bootloader statically linked to kernel inorder to boot the OS. So i'm using my slackware install to cross compile the boot loaders (u-boot) and kernel image (uImage).
I've successfully compiled the buildroot environment which has generated the arm-linux-* binaries, eg, gcc 3.4.2 for arm.
Code:
These are in a build folder (shortened in text below), which i add to my PATH
Code:
I then move to the directory where i want to build the stage1 boot loader, which is supplied in the GPL code from WD.
Code:
However the build fails with a segfault, which looks to be caused by the incorrect libraries and compiler being used:
Code:
It seems to be using my x86_64 libs and gcc 4.4.4 which is the host compiler not the target.
I've tried setting ARCH=arm but got the same results.
Do i need to export some additional variables or unset some to prevent the host files being used instead of the targets?

I need a cross compiler for C/C++.
Unfortunately, I can't find the GCC cross compiler in the repositories.
There is only a package with the binutils: cross-ppc-binutils
But nothing like: cross-ppc-gcc

I have synology nas box DS710+ that has intel atom processor inside. i've installed ubuntu under virtual box, downloaded needed toolchain for x86 processors, and decided to cross-compile openvpn.
I 've started from compiling lzo library, but first question that appeared in my head - how i have to move all compiled binaries to my synology?
1. configure - okay
2. make - okay
3. make install - this is not necessary?
Will --prefix parameter helps me? or do i have to use chroot? cause there is a plenty amount of files that i need to move to my synology.

I developed a test program(my first under linux) some thing like g++ -I$(BOOST_INCLUDE) -L$(BOOST_LIBS) threading.cpp -lpthread -lboostThread -lOtherLib -o threadingTest.out...This thing works in GCC4.5, but to compile it under windows visual studio 2008, do I have to create a new project file and then include all libs?
In short, is there any IDE or utility, where I just compile it either on linux or windows without going and modifying project options again and again ?

I have been installing gentoo on my desktop for the past few weeks. (Not a whole lot of time to get to it) and I must say that I wished I had made the move a whole lot earlier. Anyway, my next canididate for gentoo would be my ibook g3 which has a slow processor. I have heard that for these systems cross compiling is a lot better of an option than compiling on the system itself. I have read the cross-compiling guide and am left a bit confused. Could I use my thumbdrive to transfer compiled binaries from my desktop to my laptop and install the packages that way? Also, what would I do when updates come out for my laptop. Is there any way of monitoring the package statuses?

I am cross compiling a linux kernel for the mips platform. I have installed the tool chain and everything. When i try to build the kernel i get the following error message.
HOSTCC -static scripts/basic/fixdep
scripts/basic/fixdep.c: In function traps
scripts/basic/fixdep.c:377:2: warning: dereferencing type-punned pointer will break strict-aliasing rules

If i set up the toolchain on a fedora 13 machine with the exact same procedure, the cross compilation works fine. I can't figure out how this can be fixed. I am currently considering downgrading to fedora 13 due to this.

I'm a newbie when it comes to embedded linux / cross compiling. Never had to have anything to do with it b4 I bought my NAS. The Nas only has a 500MHZ ARM9 so compiling anything is painfully slow. Also only has 128MB ram. I managed to cross compile the kernel but am not sure how would you cross compile something like HPLIP for example.

I'm looking for a way to create a cross-platform GUI application. The result must be able to run on linux, windows and OSX. And it must be a point-and-click GUI.For development I should be able to rely on Open-Source tools on linux only (that means no access to Windows or OSX)The target should be able to install the result relatively easily, that means any dependencies must be freely available, and the setup steps must be very minimal (probably means no installing development tools or running compilers)
My first thought was java, but the standard Swing GUI can look a bit ugly on some platforms. So I'm wondering if there's anything else. My next thought was C++/Qt, but I don't think I can cross-compile this from Debian for Windows or OSX, can I? Next I thought of python and PyQt, but it looks like PyQt isn't available for OSX. And finally I even thought of making some kind of web application running on a tiny web server of some kind, then accessing it with a native browser, but I'm pretty sure this doesn't meet the "easy to install" criteria. I'm finding this so tricky, do all the existing cross-platform applications use natively-compiled C++ for this? Or is there an obvious alternative that I'm overlooking?

I wonder if there is an easy way to accomplish the following: I made a tool and part of it needs to be compiled. It would be easy if I can automate compilation for multiple platforms (x86 / x86_64 / RHEL / SLES / Ubuntu). Is there a way to do this automated on a single host? Or should I set up an os for each distro? Also is there a way to generate RPM and deb files also on the same host without having to edit the meta files each time a version changes?

I hve following doubts regarding cross-compiling
1. if cross toolchain build wth differnet library other than the one using presently on host, will it b matter.
2. if toolchain build for 32-bit nd if i'm running it on 64-bit will it b matter.

I did see another topic on this forum regarding VSTs in LMMS, but it didn't solve my problem. I am running using the 64-bit testing branch of debian, which may be causing some of my problems. I tried compiling LMMS myself, but I ran into an issue with wine when it tried to compile RemoteVstPlugin.
It seems as though wine didn't install winegcc or any other tools like that. After a while, I did manage to find winegcc and some of the other tools in /usr/lib/x86_64-linux-gnu/wine/bin. I decided to add some symlinks in /usr/local/bin to point to winegcc, wineg++, winecpp, and winebuild. After that, it seemed to give a different error message, but still failed to compile. It now gives me the following error:
Code: Select all[ 83%] Generating RemoteVstPlugin
/usr/bin/ld: Relocatable linking with relocations from format elf64-x86-64 (/usr/lib/x86_64-linux-gnu/wine/wine/libwinecrt0.a(exe_entry.o)) to format elf32-i386 (RemoteVstPlugin.Azfbf1.o) is not supported
winebuild: /usr/bin/ld failed with status 1
[Code] ....
I may be missing some dependencies because I couldn't run build-dep without removing skype but I don't think that's the problem. I thought the above problem may have something to do with wine, so I was going to try compiling wine to. I ran into problems with that, and ditched that idea. I really don't know what to do anymore. I can't just disable VST support, because that's why I tried to compile LMMS by myself to begin with!

I'm trying to install the calculator Qalculate from source so I download the tar.gz package for KDE from their official website to my ~/Downloads folder. I unzipped it with
Code: Select all tar xzf qalculate-kde-0.9.7.tar.gz
I moved the exploded folder to my /home/guest/ folder (my user-name is guest), I entered the qalculate-kde-0.9.7 folder and searched for a INSTALL or README file. Here's what the INSTALL file says to do. The INSTALL file says to run the following commands
Code: Select all./configure
Code: Select allmake
Code: Select allmake install
Code: Select allmake clean
After giving the first command, trouble started; here's what I got:
Code: Select allroot@aliquis:/home/guest/qalculate-kde-0.9.7# ./configure
checking build system type... i686-pc-linux-gnu
checking host system type... i686-pc-linux-gnu
checking target system type... i686-pc-linux-gnu
checking for a BSD-compatible install... /usr/bin/install -c
checking for -p flag to install... yes
[Code] .....
This is impossible, as I am running a fully functioning kde system. What should I do? I don't find the kde version of Qalculate in Apper...

I'm trying to compile a Linux kernel module called hello-2.c using the command "make -C /lib/modules/$(uname -r)/build M=${PWD} modules" (without the quotes) (which I found online), and the following is the (seemingly successful) output.:
Code: Select allmake: Entering directory `/usr/src/linux-headers-3.2.0-4-amd64'
Building modules, stage 2.
MODPOST 0 modules
make: Leaving directory `/usr/src/linux-headers-3.2.0-4-amd64'
However, I don't see a hello-2.ko (in the same folder or anywhere else for that matter). I'm Using Debian GNU/Linux 7.6.
Everything I am doing is within a folder/directory called "thefolder" (without the quotes) in the "/tmp" directory (without the quotes).
Why I can't see a hello-2.ko, and what to do to get it?

I am wanting to get be able to upload and get stuff from dropbox on my powerpc install of wheezy. Debian does not have the app for powerpc machine in stable or testing. There is a thunar extension in sid but i do not want to risk breaking my system so I decided to grab the wheezy source and compile myself.

We have a device here at work running an Arm processor, I have a cross-compiler for the device, it was distributed to our company with the linux distribution we are using on the device (montavista linux). I would love to be able to cross compile some software for this device, however, I really suck at this kind of thing.
Whenever I try to cross compile software, I usually get an error like "unrecognized host platform" (I'm paraphrasing obviously), but the toolchain is not that much different from a generic Arm toolchain, just with some extra libraries installed and stuff. I tried using other arm toolchains, but those are a crapshoot, they compile fine, but they don't always run correctly on the device (for instance, busybox).
The reason I get the unrecognized platform error is because the toolchain has a weird prefix on it (arm_v5t_le-) which the configure script can't handle, but if it would just try to cross compile it like it does with other arm targets, it would work fine. How do I make it work?

I want to run a program under ... something like strace, something like gdb. Let's call the something Fred. Every time I run a particular program under Fred, it detects when a system call is about to take place or a signal has occurred, and traps to Fred, which decides dynamically how to respond, whether the stimulus is a signal or an attempted open(), close(), read(), write(), socket(), connect(), listen(), select(), ioctl(), time(), or whatever. Although strace does this marvelously, what I'd like Fred to do is use code that I supply to doctor up what the subject program sees. In the case of write(), it should be able to modify what actually gets written. In other words, a hard shell environment around the program which completely mediates between the subject program and the outside world. I'll start with the source code for strace and gdb if I have to. But has this been done already?
