Ubuntu :: Compile From The Source Code To Optimize Hardware
Feb 7, 2010
Recently I was trying to use Gentoo, and I was really impressed of how it is faster than Ubuntu in running applications, specially when I build wine and was able to run Oblivion at a reasonable speed. I would like to know if there is a way to compile Ubuntu from source code, to optimize it to my hardware.
I downloaded wine from a windows laptop, but because you have to have a computer running Linux to download it as a .deb package, I had to download the source code as a tar. bz2.
Does anyone know how I compile it and make it executable?
I am trying to install a DR rootkit into ubuntu for an assignment, im using vm ware but can only get as far as extracting the rootkit and not being able to compile the source code.. when i use the ./configure command it says there is no such file or directory and when i use the make command it keeps getting errors.
I've created a GUI for my voip software wherein i'm using the source code of linphone 3.3.2 for video and all protcol stuffs . It is like i've got my own gtk GUI instead of the linphone's glade . Hope you get the picture of what i'm doing . I would like to know how to compile the source code since because i do not know about make files and stuffs . Kindly help me solve this .
I've taken the source code for Zlib1.2.3, built and installed in a 64 Bit linux machine. Then when i downloaded Python 2.5.4 source and tried to build(make), i got the following error
gcc -pthread -shared build/temp.linux-x86_64-2.5/opt/cinecert/Python-2.5.4/Modules/zlibmodule.o -L/usr/local/lib -lz -o build/lib.linux-x86_64-2.5/zlib.so /usr/bin/ld: /usr/local/lib/libz.a(adler32.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libz.a: could not read symbols: Bad value collect2: ld returned 1 exit status
Where do I find the linux-source package and the linux-headers package? Are they on the CD that I can copy to /usr/src (is that the right place...)? Or do I need to download them from the old-releases.ubuntu.com site?
The issue now is that the nVidia installer from their website wants the source code to build the right packages for this machine, however, I do not have the src directory with the source code that it is looking for. Is there some way to give this too it now?
i am already a little bit familiar with linux and now i want to know better the linux OS. i have downloaded the source code of the krnel from the kernel.org and i dont understand the linux source trees organization, so can somebody do me a favor and give me a link to some internet page (or at least a book) that explains that?? i have searched in the internet with the tag:::linux source trees organization and i have not found nothing interesting
I'm trying to compile some code [URL], which uses Glib. I have the libglib2.0-dev package installed, but running ./configure reports that Glib is not installed. Is the autoconfig script wrong or out of date, or do I need something else installed?
After updating to natty I cannot compile any Gtk+ code, no matter what I do I get linker errors. This is not a problem with the way I'm building it, I'm familiar with the correct usage of pkg-config.
Even this code will fail to link: Code: #include <gtk/gtk.h> int main(int argc, char** argv) { gkt_init(&argc, &argv); gtk_main(); } (Compiled with the standard commands to compile Gtk+ stuff)
I always get the following output: Code: /usr/lib/libgtk-x11-2.0.so: undefined reference to `g_source_get_time' /usr/lib/libgtk-x11-2.0.so: undefined reference to `g_get_monotonic_time' /usr/lib/libgdk_pixbuf-2.0.so: undefined reference to `g_simple_async_result_take_error' /usr/lib/libgdk-x11-2.0.so: undefined reference to `g_slist_free_full'
I do a lot of programming and I have to compile the code quite often. It's not convenient to move to the directory that contains the source code every time I want to compile it. So is there a way to compile a code from the my current directory (say /home example) without moving to the directory that contains the source. I remember being able to do this but forgotten how.
EDIT: I'm using makefiles to compile. Lets say I'm in the home directory and when I type
i try to compile a c code which uses SSH library,but i get this error
Code: libssh.h: No such file or directory
i searched and i found that This happens if a library used for linking is not present in the standard library directories used by gcc.
By default, gcc searches the following directories for header files:
/usr/local/include/ /usr/include/
and the following directories for libraries:
/usr/local/lib/ /usr/lib/
i update my libssh from libssh-0.4.2-1.fc13.i686 to libssh-0.4.6-1.fc13.i686, and there are files called libssh.so.4 and libssh.so.4.0.2 in /ur/lib, but i still can't compile it with this command:
I am unable to compile C++ program in terminal. Whenever I try to add "#include<iostream.h>" it shows an error and thats why I can not use "cout" and "cin" functions. I installed g++ for this but the problem persists.
I have legacy fortran 77 code that used to compile seamlessly using g77 on an old machine. I've tried to recompile it on a new machine (old one is dead) using the original makefile, but the linker fails under g77, while there are persisting syntax errors using gfortran. I have two source files readmixed.f and subroutines.f. Under g77 the object files are produced using
$ f77 readmixed.o subroutines.o -o readmixed subroutines.o(.text+0x0): In function `norm1_': : multiple definition of `norm1_' readmixed.o(.text+0x3987): first defined here
I'm trying to write a helper for the mount utility (mount.truecrypt) and there are some things in the util-linux-ng package that would be helpful. For example, in fstab.c, there is a lock_mtab() function. I want to be able to do something like:
Code:
#include "fstab.h" int main(int argc, char *argv[]) { lock_mtab();
[code]....
But I don't know how to compile it. I was trying (naively) something like:
But I guess the problem is fstab needs a whole bunch of other stuff. Should I just build the entire util-linux-ng package and then use the output somehow? If anyone is interested in mount.truecrypt (to be compatible with mount and /etc/fstab) you might be interested in giving me a little bit of guidance. I've got enough code to build the actual truecrypt command thus far. In fact, it's useable, but not robust (ie, doesn't lock the mtab, etc). You can browse the source for util-linux-ng here: [URL] and download a tagged release here:[URL]
how to compile assembly code in linux? I am using AMD processor code instructions...is that amd registers inbuilt? with what file extension i should give while writing assembly code program?
I've been trying to work out a way to stop chunks of code being compiled using a variable in my makefile but can't work it out. What I mean is for example in my code I might have.
/****output comms portdata********/ printf(" debug comms port %d",ReadPort("ttys1);
I only wish this code to be compiled when I'm debugging. What I've tried is using #ifdef with
#ifdef COMM_PORT_DEBUG printf(" debug comms port %d",ReadPort("ttys1); #endif
Then in my make file I set COMM_PORT_DEBUG to 1 so
DEBUG_DEFS = COMM_PORT_DEBUG=1
I then thought I could put it into my in my link line
I have been using Linux for 2 months, specifically Ubuntu, and been wondering where the source code is. Not only do I wonder where the kernel source code is but also where the source code for the installed programs are.
Wanted to switch to Kubuntu and decided a clean install was the way to go. Though the learning curve isn't too tough, I've hit a serious snag: When I try to compile a source package according to the similar instructions in each of the README files, I get the same error message;
Instructions:
mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` .. make su -c 'make install'
[Code].....
I'm liking this KDE 4.4 setup, but if I can't install the improvements from kde-look.org
trying to install the latest version of Minitube on my 64 bit Ubuntu 10.04 installation. I thought adding a PPA would let me upgrade from version 0.9 to the latest version but it didn't seem to work. So now I'm trying to install from source (I've never done this before so I'm a complete noob when it comes to compiling). I checked the install instructions in the source which reads:
Code:
# Build instructions ## Prerequisites
To compile Minitube you need Qt >= 4.5 installed.On a Debian or Ubuntu system just type:
Windows and Mac users can get the Qt libraries from:
[URL]
Compiling on Linux is fairly easy. Just run:
qmake and then make
Beware of the Qt3 version of qmake! If things go wrong try running qmake-qt4 instead.
## Running
Just type:
./build/target/minitube
I installed the prerequisite packages,but just to be safe I wanted to run the ./configure command, but when I try to I get the "bash: ./configure: No such file or directory" message. Any idea what I'm doing wrong? Also, based on what I've read, I should have to enter some kind of install command in order to install the compiled binary but the instructions make no mention of this.
I often like to use packages that have to be compiled from source. However, even after downloading gcc, I can't compile anything, because the configure script gives me a message about being unable to execute C programs. I gather that this is because of a "noexec" option in /proc/self/mounts. Problem is that the file apparently cannot even be edited by root. Perhaps there is an alternate type of fedora distribution I could use?
How do you compile a tar.gz source on slackware?I am asking because I am about to download and install Slackware(x64), and I have some drivers that it may not have (Ubuntu didn't have them) and TrueCrypt source.
Has anyone successfully compiled VLC 1.0.0-rcX (rc1, rc2 or rc3) from source on CentOS 5? I have a binary installation of VLC 0.9 but I would like VLC 1.0 as it has a new codec that I'd like to use. I've tried lots of ideas which I can post - I keep getting build errors due to wrong package versions - but I thought I'd ask to see if anybody has a HOWTO first.
I am trying to build the java gnome gtk+ bindings on open suse and ran into a snag. the libcairo2-dev package is not apart of pensuse - how ever it is apart of ubuntu and the debian launchpad. can i install other distros repos to solve this issue? actually no i cant. how to install this package? zypper install libcairo2-dev comes back as not found.
