Make: undefined reference to 'check_nan'

[fabero]

I pulled the source code from the master branch and ran cd glove && make . However, this results in the following error. Does anyone know what the cause of this is? The version of release 1.2 does build, but it returns an error when running demo.sh , so I am kind of stuck here.

Could this be an issue with the compiler treating the function as an extern by default? In other words, you might be able to make progress by changing line 145 to

static inline real check_nan ...

I'm in no way a C compiler expert

This resolved the issue for me.
