How can I compile a C++ application using g++ with x86 platform settings on a x86_64 machine ? What are the possible negative side-effects of compiling a C++ application with x86 settings on a x86_64 platform ?
View 6 RepliesI have been using gcc to compile C programs.
I want to know what exactly is the meaning of Compiling a C program.
I checked
cc -S prog.c
will give an .S file and if you analyze the hexdump I saw some assembly instructions.
So what does the compiler do which is not required in case of interpreted languages?

So I completely fail at making a kernel x86_64, used to make them fine for just x86 but I haven't a clue on how to make them specifically for 64-bit systems.
View 3 Replies View RelatedI 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 am having problems with my touchpad on my dv7 notebook, that I can not resolve... so I thought it would be a good idea to update the gpointing-device-settings that came with the opensuse 11.3 repositories (version 1.3.1-1.2 too old maybe)
So I downloaded the source files but when I try to ./configure, I have some errors telling my that my gtk+ and gnome-settings-daemon versions are older (that is not true, I check them and they are newer)
Here is the ./configure output:

Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix.
Alternatively, you may set the environment variables GNOME_SETTINGS_DAEMON_CFLAGS
and GNOME_SETTINGS_DAEMON_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

I'm an new to Slackware.I want to ask how to run 32bit program on x86_64.
My Slackware is 13.1 x86_64.
I am having a problem with a simple program I wrote in Fortran (gfortran). This program basically reads a long list of numbers and makes some operations with them. Double precision is used in the variables and functions, and AFAIK everything is in order with the program. The thing is that I accidentally noticed that said program yields different results, and I am talking about integers being different, something noticeable. Apparently the offending chunk of code might be:
Code:
DOUBLE PRECISION FUNCTION tamano (x1,y1,z1)
DOUBLE PRECISION x1,y1,z1
tamano=dsqrt((x1)**2+(y1)**2+(z1)**2)
[code]....
One of the involved machines has F15 x86_64 and the other one F15 i686. My first guess is that this has something to do with how Fortran handles precision (which I supposed was the same for 32 and 64 bits). To compile the program I use:
Code:
gfortran --free-form -fno-whole-file program.f90
Is there another option I should pass the compiler to make sure the same precision is used in both cases? Or what can I do here?
I was reading the following forum guide:openSUSE software installation hints So I decide to install from the souce code the following webcam application:

I looked at other topics with similar problems and I have both wxGTK and wxGTK-devel installed. I'm pretty sure the method of compiling is correct.

Recently i have installed fedora 13 my laptop but when i try to compile a c program it says that gcc command not found.

or is there any other solution.

I'm sometimes compiling a piece of software on my Fedora 13 machine and then transferring it to an Ubuntu box. Recently I noticed this would yield issues with Fedora's .so files:
Given I had a program's binary and an .so file the program would attempt to load, both compiled on Fedora, the program would run fine on Ubuntu 8.04 LTS but would be unable to load to open the Fedora .so with an "ELF file OS ABI invalid" error.
Now any program I natively compile on Ubuntu which I run on Fedora instead, will throw the *same* error with Fedora .so's - so basically neither a Fedora bin on Ubuntu, nor an Ubuntu bin on Fedora can load the Fedora .so files, only a Fedora bin natively on Fedora can.
That means Fedora .so files are always a problem on Ubuntu, and Ubuntu bins are always a problem on Fedora (unable to load system libs there).
This is a bit odd for e.g. binary redistributions of programs (which are rare I know) and I also found out that e.g. Tibia's linux client suffers from this issue (throws "ELF file OS ABI invalid" on my Fedora 13 when attempting to load my system's libGl).
And I started to wonder whether the only way to work-around to get something that works on all platforms is a Fedora binary shipped with .so files compiled on Ubuntu - which seems a bit stupid and ridiculously complicated just to get something that works flawlessly everywhere. Isn't there e.g. a gcc switch that will allow me to compile the .so files on Fedora in such a way that they can also be used on an Ubuntu system so just compiling everything on Fedora, yet getting it to work on Ubuntu aswell would be possible?

I decided I was going to compile XChat from source today for "fun." What I ended up doing was spending a few hours getting it to compile, then find out everything didn't work the way I thought it did. I was under the impression that after I ran "sudo make install" I was "upgrading", when in reality I'm just installing a seperate version alongside the old one. Apparently I have to keep the old version so every program that was compiled with it will continue to work, so how do I:
1) Force a program to use a specific version of GTK when compiling.
2) Find where my version of GTK installed to.
I've asked some people and I've just been told to "learn LD_PRELOAD". I've googled and can't figure how I could even apply that to my current problem
