Help I need to compile 32-bit gtk app on x64

[nolag]

I currently am doing this with a chroot. The solution is not ideal (as it takes a lot of space and constantly requires me to chroot) I would much rather just do -m32 (right now it won't find the gtkmm headers stuff). I would like to be able to install the gtk 32-bit librarries in the lib32 folder with apt-get like I did for the 64-bit. Is this possible? Any help is greatly appreciated :D.

Hi,

As far as I can tell the gtk+2 libs are part of the ia32-libs package. You can test this by doing dpkg -S /usr/lib32/libgtk-x11-2.0.so.0 with ia32-libs installed.

You will also need to have the '-dev' package installed (which includes the header files), but this is platform agnostic.

I compiled the following code with "-m32" on my amd64 box and had no problems running the result:



#include <stdlib.h>
#include <stdio.h>
#include <gtk/gtk.h>

int main(int argc, char* argv[])
{
gtk_init(&argc, &argv);


gtk_main();

return 0;
}


compiled with:


gcc -m32 `pkg-config --cflags --libs gtk+-2.0` -Wall gtktest_main.c -o gtktest
'file' output:
./gtktest: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs),

Great, thanks. I am wondering though can you do this for gtkmm? I have a school app I would like to cross compile.
