Description Kyle Edwards 2014-05-31 23:35:02 UTC
When compiling with the CLANG compiler on FreeBSD 10, the configure.ac check for isinf() fails with the message "error: controlling expression type 'int' not compatible with any generic association type".

This is because the script checks using "isinf(1)", and CLANG does not automatically convert this to a float or double, and gets mad about it. Annoying, I know.

I have a patch I'm currently testing that changes this to "isinf(1.0)". I will post it if Mono successfully compiles on my machine.

Patch to fix the isinf() test in configure.ac

Alright, I tested my patch and it made Mono compile successfully under CLANG on my FreeBSD 10 machine. I've attached the proposed patch.
