pyxplot @0.9.2_2 is not UsingTheRightCompiler

[ryandesign (Ryan Carsten Schmidt)]

pyxplot is not UsingTheRightCompiler -- the configure script isn't, at least. It is hardcoded to run gcc.

[Schamschula (Marius Schamschula)]

It checks for gcc, and will accept nothing else…

I've written a patch to check for clang if gcc is not found.

The compiler defaults to CC, which by default is /usr/bin/cc -> clang

[larryv (Lawrence Velázquez)]

So now the configure script checks for gcc and then clang? That will produce false positives if someone has an actual GCC installed that comes before /usr/bin in $PATH.

Can you not patch the configure script to actually look at the value of $CC?

[Schamschula (Marius Schamschula)]

Good point, Larry.

I've simplified the configure script to just check for cc.

[Schamschula (Marius Schamschula)]

Use "echo $CC" rather than "which cc"

[ryandesign (Ryan Carsten Schmidt)]

What I actually meant was all of the subsequent times that the configure script explicitly invokes gcc, for example:

if printf '#include <stdio.h>\n#include <readline/readline.h>\nint main() { return 0; }\n' | gcc -x c - -o conf.out > conf.stdout 2> conf.stderr

It should just use $CC.

[Schamschula (Marius Schamschula)]

Ah.

I was only looking for the part where the script is looking for the compiler itself.

The updated patch makes the balance of the substitutions.

[ryandesign (Ryan Carsten Schmidt)]

The build still doesn't use the right compiler. The Makefile uses $(CC), but the value of CC that was set at configure time isn't remembered anywhere by the build system. Could fix by having the configure script write the value of CC to a file that's included in the Makefile, or by passing the value of CC again as an environment variable in the build phase.

[Schamschula (Marius Schamschula)]

Use build.env to use same CC for build as configure.

Also noticed that there was a rev bump due to the recent ghostscript update.

[ryandesign (Ryan Carsten Schmidt)]

Committed in r140051 with a small change: instead of merely checking whether the CC environment variable is non-empty, it verifies that running it actually works. It also defaults CC to "gcc".
