Orange C failed to link on FreeBSD

Here is the error message on FreeBSD:

How did you run the build? I guess with GNU make?

As we already found out in the other thread #1044, the Makefile shouldn't use -D__MSVCRT__ on this environment #1049 and additionally needs -lm.

Of course. The command is gmake. If you use only make, it will invoke BSD make (bmake) instead.

gcc and g++ on freebsd don't display this behavior for whatever reason but clang and clang++ do. I can confirm that adding -lm as the LINK flag fixes the issue with the linker crashing out, however. When I do my big "Add verbosity/mkfifo" changes I'll push a fix for this.

gcc may automatically add -lm I'm not sure....

[GitMensch]

This depends on the spec file that is installed - gcc's configure machinary checks for libraries it always need to link "specific for this machine", and adds it there.
