Hello, trying to compile 2.0.2 (latest released archive) on Mac OSX 10.9 on MBP Core i7, I get the following error:

I've found the problem. The default configuration in the included config file assumes Linux. By modifying lines 43-47 of the makefile, it compiles just fine.

vschiavoni commented 10 years ago

The remaining problem remains related to these warnings:

buffer.c: In function 'buffer_meth_send':
buffer.c:83:15: warning: unused variable 'tm' [-Wunused-variable]
buffer.c: In function 'buffer_meth_receive':
buffer.c:114:15: warning: unused variable 'tm' [-Wunused-variable]
