Building socat in OS X 10.7 Lion

socat (1.7.2.0 as of this writing) doesn't compile with the clang, the standard compiler in Mac OS X 10.7 Lion (10.7.2 as of this writing). It does compile if instead of clang one uses for example llvm-gcc-4.2.2.


The developer reports that this is a bug; only gcc is supported in socat, but there are compatibility fallbacks for other compilers. Only, the fallback was missing on the file that fails to compile, xioexit.c. The fix is easy:

@@ -5,6 +5,7 @@
/* this file contains the source for the extended exit function */

#include "xiosysincludes.h"
+#include "compat.h"
#include "xio.h"

(if someone is trying to build something like socat, I guess he doesn't need help about patchfiles)

This problem was also present in MacPorts' port for socat. I have already reported it and provided a new working portfile, so I guess it won't be long until it is published.
