glib2 @2.30.2 cannot run C compiled programs

[giordano.marcello@…]

I'm trying to compile glib2 on my Macbook pro, Os 10.7.2, Xcode 4.2

The configure stage fails with this error output

checking for suffix of executables... 
checking whether we are cross compiling... configure: error: in `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_glib2/glib2/work/glib-2.30.2':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.

The config.log is attached

The log shows:

error: /usr/local/include/stdio.h: Permission denied

Remove this file and anything else in /usr/local; software installed there often interferes with MacPorts, as it has done in this case, which is why we don't support having software installed there. Once you've removed it, "sudo port clean glib2" and try again.

thank you for pointing this out. turns out that the permission in /usr/local were messed up (700 instead of 755). Once I fixed that everything compiled smoothly,

Thanks again!
