Compilation 32bit on 64bit plateform (advenced) [message #895563]

Hi,

I ve already read the other topics that talk about this subject but it does not help me..

My problem : i can't compile my program for 32bit on a debian which is 64bit
I am using Eclipse c++ btw

I saw Axel Mueller say :
To build 32Bit applications on a 64Bit platform you need:
- gcc/g++ with multilib
- ia32-libs (needed to link and run your application)
- in Eclipse you add -m32 to the compiler and linker flags

I did not have g++-multilib so I installed it by apt-get install g++-multilib. But i dont know if eclipse use the new or the older g++.
I hadnt got ia32-libs either so I did apt-get ia32-libs too.
But i dont know how to use it..

And Ive read on the internet that the option -m32 in project/properties/c/c++build/settings/GCC C++ Compiler/Command should work

But even though I tried it, I cannot make it work.

Any help would be appreciated

Thanks.

There is still only one g++ binary. The only difference is that g++ from the g++-multilib can compile for 32 and 64 bit.

You don't have to do anything. The linker and your 32bit application will use the correct libs.

Can you be more specific. What does not work? Any error messages?

Thanks for ur answer

First, I dont understand how the lib ia32 will be linked to my application if i dont add it in project properties/c++ linker/librairies..

Second, i am working on Debian 64 bit and using the graphic librairy "Foxtool kit" so I install it like this (./configure make make install) but it is compiled for 64bit system so when I compile my application that needs Fox lib (g++ -m32 -L/root/Documents/lib/64bit -o"testfox" ./NotreWindow.o ./main.o -lFOX-1.6) the error message is :

/usr/bin/ld: skipping incompatible /root/Documents/lib/64bit/libFOX-1.6.so when searching for -lFOX-1.6
/usr/bin/ld: skipping incompatible /root/Documents/lib/64bit/libFOX-1.6.a when searching for -lFOX-1.6
/usr/bin/ld: skipping incompatible /usr/local/lib/libFOX-1.6.so when searching for -lFOX-1.6
/usr/bin/ld: skipping incompatible /usr/local/lib/libFOX-1.6.a when searching for -lFOX-1.6
/usr/bin/ld: cannot find -lFOX-1.6

I have compiled Fox in Debian 32bit as well and I import it in my Debian 64bit and I try this :
g++ -m32 -L/root/Documents/lib/32bit -o"testfox" ./NotreWindow.o ./main.o -lFOX-1.6
The error message is :
/root/Documents/lib/32bit/idth(wchar_t) const':
FXFont.cpp:(.text+0x1clibFOX-1.6.a(FXFont.o): In function `FX::FXFont::getCharWf6): undefined reference to `XftTextExtents32'
(999999 errors like that)
The compiler does not recognize anything in the lib..
I dont know how to do it.

Firstly, you have to compile Foxtool kit library as 32bit version on your 64bit host. Have a look at the configure options to see how you can pass gcc compiler flags http://stackoverflow.com/questions/3261909/build-32bit-on-64-bit-linux-using-a-configure-script

When I compile FOX (64 bit standard) it works, I can create an application that uses FOX, perfect.

But, when I add -m32 to complile FOX, the error message appears :
skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../libGLU.so when searching for -lGLU

I know FOX uses GLU library and i have it in my system but in 64bit version!

It is always the same problem :
I tried to compile my application in 32bit, but I could not because I have FOX in 64bit.
And now I am trying to compile FOX in 32bit, but I cannot because I have GLU in 64bit..
Endless problems..

How I can do it please? There must be a solution.

I have figured out how it works so when i compile FOX in 64bit it works.
But when i want to compile in 32bit the error message appears :
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../libXft.so when searching for -lXft
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../libXft.a when searching for -lXft
/usr/bin/ld: skipping incompatible /usr/lib/libXft.so when searching for -lXft
/usr/bin/ld: skipping incompatible /usr/lib/libXft.a when searching for -lXft
/usr/bin/ld: cannot find -lXft

I dont understand why, because in FOX properties/C++build/settings/C++linker/libraries/ I change the path to : /usr/lib32/ (libs given by package ia32-libs)

root@solinnen:~# ls /usr/lib32/libXft.so.2
/usr/lib32/libXft.so.2

I dont understand why it tries to link libXft from /usr/lib/libXft.so !

Someone has an idea?

It seems you did not pass "-m32" to the linker. Did you use the configure command line I quoted in my last post? Did you clean up before calling configure?

I passed the option -m32 to the compilater and linker.
The stronger is that if i delete Xft in in FOX properties/C++build/settings/C++linker/libraries/, FOX is compiled. But in xterm:

g++-4.4 -m32 *.cpp -I /usr/local/include/fox-1.6/ -L ../FOX/Debug/ -lFOX

Logic errors! It is trying to link 32bits libraries to FOX which has just been compiled in 64bit.
But why does not it respect this path when i try to compile FOX in 32bit.

I dont understand anything anymore.. ldconfig problem?

It works when i compile in the term :

root@solinnen:~/Documents/testfox# g++-4.4 -m32 *.cpp -I /usr/local/include/fox-1.6/ -L ../FOX/Debug/ -lFOX -L /usr/lib32/ /usr/lib32/libXft.so.2

But i do not understand, if someone can explain to me?
Now how can i do this compilation in Eclipse?

That's weird. It should search in /usr/lib/gcc/i686-linux-gnu/4.4.5/../../../
Did you call "make clean" after adding the "-m32" option? Perhaps there are some leftovers.

Now how can i do this compilation in Eclipse?

In this case you explicitly name the Xft library to use for linking (remember: -L is usually for the library path). You can user this approach in Eclipse, too. You have to tweak the settings C/C++ Build->Settings->Linker settings

It works. I add /usr/lib32/ in FOX properties/C++build/settings/C++linker/libraries/library search path(-L) but i can not add /usr/lib32/libXft.so.2 in FOX properties/C++build/settings/C++linker/libraries/libraries(-l).

So i add it in FOX properties/C++build/settings/C++linker/Miscellaneous/other object
I find it dirty but it works.

Now i export my 32but application on my 32bit Debian:
./exe: error while loading shared libraries: libFOX.so: cannot open shared object file: No such file or directory.

Fox is a shared library because only with shared librares you have the option C++linker in properies if not how link others libraries (-lX11, -lXft, -lGLU) to a static library?

What does ldd print out? Is libFOX.so in your /lib directory?
