Cross compile from Mac to Linux with hxcpp

It is possible to use the hxcpp build tool to compile linux 32/64 binaries from a Mac Box. “Why would you want to do this?” I hear you ask. Well, I use this so I can run all my builds from a mac-mini, with windows running in VirtualBox. I know there are other ways, but having a single little box doing all the work is pretty easy to manage.

To do this, you just need to setup the HXCPP_XLINUX variables. There are a number of ways you can do this, but the ~/.hxcpp_config.xml file is probably the cleanest place.

Having installed the cross-compilers from, is it just a matter of pointing to the executables using some xml entries:

<set name="HXCPP_XLINUX64_CXX" value="/usr/local/gcc-4.8.1-for-linux64/bin/x86_64-pc-linux-g++" />
<set name="HXCPP_XLINUX64_STRIP" value="/usr/local/gcc-4.8.1-for-linux64/bin/x86_64-pc-linux-strip" />
<set name="HXCPP_XLINUX64_RANLIB" value="/usr/local/gcc-4.8.1-for-linux64/bin/x86_64-pc-linux-ranlib" />
<set name="HXCPP_XLINUX64_AR" value="/usr/local/gcc-4.8.1-for-linux64/bin/x86_64-pc-linux-ar" />

<set name="HXCPP_XLINUX32_CXX" value="/usr/local/gcc-4.8.1-for-linux32/bin/i586-pc-linux-g++" />
<set name="HXCPP_XLINUX32_STRIP" value="/usr/local/gcc-4.8.1-for-linux32/bin/i586-pc-linux-strip" />
<set name="HXCPP_XLINUX32_RANLIB" value="/usr/local/gcc-4.8.1-for-linux32/bin/i586-pc-linux-ranlib" />
<set name="HXCPP_XLINUX32_AR" value="/usr/local/gcc-4.8.1-for-linux32/bin/i586-pc-linux-ar" />

Then you can build from a “build.n” (such as in $HXCPP/project) file using:
