/usr/bin/ld: skipping incompatible foo.so when searching for foo

Question

I am using Ubuntu 13.10 64bit and I am getting the following errors while compiling the python wrappers of vlfeat library.

g++ -o _vlfeat.so ../../vl/aib.o .         


        

Answer 1

remove -m32 in command line flags

to build with 32bit binary, you have to install

sudo apt-get install gcc-multilib and sudo apt-get install ia32-libs-dev
