Because the width of
unsigned long varies between architectures, some tests are only run on 64-bit systems and others are only run on 32-bit systems. On a typical x64 Linux system with glibc, the default toolchain will be
x86_64-unknown-linux-gnu, but you can run the 32-bit tests by installing the 32-bit glibc toolchain:
rustup target add i686-unknown-linux-gnu
To run tests for both 32bit and 64bit
c_ulong on a 64-bit host:
cargo test cargo test --target i686-unknown-linux-gnu
You should see different tests running in each case.
Testing other OSs
There are various vagrant boxes defined in the Vagrantfile. Windows and macOS are a pain to set up build tools on, but eventually the code will compile there, though of course it won't work properly. It should work fine on all Linux boxes and the FreeBSD one.
