- Update the build.sh and fix some typos.
+ Don't add the OSX ones because I have not tested them and it won't
even build anyway due to the libaio dependency. Needs to use POSIX AIO
or something else.
- They are rather simple and all the magic happens in two lines.
+ First line tells cmake to get ready to compile FOR linux or darwin.
It also sets CMAKE_CROSSCOMPILING to true which is the only way to
let cmake known that we are using stuff not from the host.
+ CMAKE_C_COMPILER/CMAKE_CXX_COMPILER are basically used to detect
the architecture of the target. Since I used generic cc/c++ the
hardcoded -m32 is needed to ensure we get TARGET=i386. Also
since I hardcode -m32 and use c++/cc it's to be noted that
we can only do i386->i386 (trivial), amd64 -> i386, and x32->i386.
.
Using something like i586-linux-gnu-{gcc,g++} would also work and
enable arm -> i386, etc but it's infeasible and impractical to do all
the combinations. File is simple enough that a distro or user can
create their own and cross compiling is rather tedious compared
to using a chroot to compile it.
- I tested it in Debian with "dpkg-buildpackage -ai386" but installing the
build dependencies was rather tedious.
