Gnuplot 4.6.5 Build Failure

[gdesjouis@…]

After an upgrade to OSX 10.9:

• I uninstalled and cleaned all ports
• uninstalled macports
• updated XCode to 5.1.1
• reinstalled macports

and then tried unsuccessfully to install gnuplot

./stdfn.h:143:12: fatal error: 'varargs.h' file not found

Please attach also config.log. There are a bunch of things that I don't really understand, including the failure to find AquaTerm, the following warning:

WARNING: No C++ compiler found. The wxWidgets terminal will not be compiled.

and a few other things. I don't think this is a generic issue since many other people managed to install gnuplot without problems, but I'm curious to know how you ended up in that branch of the code.

There's this code in src/stdfn.h:

#if defined(HAVE_VFPRINTF) || defined(HAVE_DOPRNT)
# ifdef STDC_HEADERS
#  include <stdarg.h>
#  define VA_START(args, lastarg) va_start(args, lastarg)
# else
#  include <varargs.h>
#  define VA_START(args, lastarg) va_start(args)
# endif /* !STDC_HEADERS */
#else /* HAVE_VFPRINTF || HAVE_DOPRNT */
# define va_dcl char *a1, char *a2, char *a3, char *a4, char *a5, char *a6, char *a7, char *a8
#endif /* !(HAVE_VFPRINTF || HAVE_DOPRNT) */

but on my machine the first if is false.

(You might also ask for help on the gnuplot-beta mailing list.)

There is something that shouldn't have happened and is not related to gnuplot:

/usr/include/libc.h:40:10: fatal error: 'stdarg.h' file not found
#include <stdarg.h>
         ^
1 error generated.

It seems as if something was wrong with your compiler setup. Did you also reinstall Xcode command line tools?

Please ask on the macports users mailing list for help. I'm not sure that I know how to help you.

[gdesjouis@…]

Ok, thanks, I did install the Xcode command line tool. I'll try to see on the macports users lailing list.

The config.log shows that your version of Clang is:

Apple clang version 2.1 (tags/Apple/clang-163.7.1) (based on LLVM 3.0svn)

As shown in XcodeVersionInfo this is the version of Clang that came with Xcode 4.1 on OS X 10.6. This is not a suitable compiler for OS X 10.9. Please reinstall the latest version of Xcode and the Xcode command line tools per our installation instructions to get a suitable compiler.
