[Ns-developers] Compilation on MinGW-x64

[vincent@clarinet.u-strasbg.fr]

Hi Josh,

Unfortunately, I still got the -fPIC error. I see in our waf's gxx.py that
it still has the check for "32-bit only" that remove the -fPIC.

By the way I have found 3 compilation problems in utils/test-runner.cc:

- missing limits.h for PATH_MAX;
- mkdir on Windows does not take two parameters (name and rights) but just
one (name);
- srandom()/random() do not exists on MinGW but can be replaced by
rand()/srand().

Here a patch that address these problems. If OK I will commit it.

Best regards,
