I’m currently writing a little program in c++ on my 64bit Ubuntu Pc. By default eclipse compiles the program for a 64bit architecture. Since I want to use my little program on my server which is still 32bit, I need to be able to compile my program for 32bit. How could can I do that in eclipse? I’ve been fiddling for a while with the settings but nothing worked…
Cheers
I found the answer myself, after lots of searching and trying things out. This is a solution that works if you happen to have the same problem.
For this to work the following packages have to be installed:
gcc/g++ with multilib
ia32-libs
Then right click on your project, and select “properties”.
Go to “C/C++ Build” and choose “settings”. Under “GCC/G++ Compiler” add “-m32” to the command field (the field should now say “g++ -m32”).
Do the same for “GCC/G++ Linker”.
Now that you have added the flag, this should be compiled for 32bit.
I’m using Eclipse Galileo, for the case that your interface looks different.
I only added the “-m32” flag only under the “Release” profile, so my “Debug” builds are still 64bit.
