I tried that but it didn't help. I happened to find something that worked though. I added #include </usr/include/stdio.h> in the following files in the compat directory: assert.cc xalloc.cc xstring.cc xstrerror.cc I also had to use the --disable-strict-error-checking flag when running the config script. Now it builds like a charm. Thanks for looking into it though :) -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-3-2-doesn-t-build-in-CentOS-6-tp4664383p4664443.html Sent from the Squid - Users mailing list archive at Nabble.com.
