How 64bit FastCGI library can be built within 32bit Linux Mint?

Question

I am able to build 32bit FastCGI library in 32bit Linux Mint using this sequence:

./configure
make
make install

But how should I change files in order to build 64 version? I've already installed multilib for gcc and g++.

Answer 1

It is possible to compile 64 bit applications on a 32 bit machine, but you will not be able to run them.

I beleive all you would have to do is pass CPPFLAGS+=-m64 to the compile line and voila. The configure.sh probably takes optional parameters for you to specify the build environment manually.
