gnuplot: configure: error: cannot run C compiled programs

[netja000@…]

I tried to build gnuplot from my MacBook Pro 10.7.5. The Xcode version is 4.6.3, and the MacPorts base is 2.2.1. And I got following error messages:

In the main.log, it seems none of the URLs is working:

Please let me know what I can do to solve the problem. Thanks a lot! :-)

Irrelevant. That's MacPorts trying to download pre-compiled binaries. Since apparently none exist for this port, it then tries to compile the source. That then fails, and that's the problem we need to investigate.

Please let me know what I can do to solve the problem. Thanks a lot! :-)

The log you attached says:

:info:configure configure: error: cannot run C compiled programs.
:info:configure If you meant to cross compile, use `--host'.
:info:configure See `config.log' for more details

So why can't you run C compiled programs? Have you installed the Xcode command line tools? See wiki:FAQ#missingxcode. What does the config.log say?

I'm clueless. It might help to see config.log though:

Error: Failed to configure gnuplot, consult /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_gnuplot/gnuplot/work/gnuplot-4.6.4/config.log

Please attach that one as well.

Thanks for your replies.

I just attached the config.log. I also attached the screenshot of the Xcode's preference, which shows that the Xcode command line tools installed and no updates can be found.

[mojca (Mojca Miklavec)]

You must have installed some third-party software. Xcode doesn't install files to

/usr/local/include/stdio.h

Please try to figure out what software that is and remove it. That is: make sure that you won't have any leftovers in /usr/local/, at least not in include/ and lib/.

[mojca (Mojca Miklavec)]

PS: I would be intersted to know what software that is. And in case that the problem isn't solved after you remove everything from /usr/local, please open a new ticket or reopen this one.
