[leiradel]

It was already failing to build for Android. For Linux, I believe the link command is missing a -lm. Can you please see if that fixes the build?

[leiradel]

The Linux makefiles in the build folder already include -lm. If you build with

$ make platform=linux_x86_64

or linux_x86, it should build correctly. I'll try to fix Makefile.libretro to add -lm for Linux.

[orbea]

Yes, make platform=linux_x86_64 works.

[orbea]

This also works.
