Summary: ImageMagick fails to build on 10.6.5ImageMagick: expected '#pragma omp' clause before 'omp_throttle'

Hmm, it builds fine for me on Snow Leopard. "omp" here refers to OpenMP but I'm not sure what to do with this.

If you attach your config.log I could compare it with mine, see what's different.

comment:4 Changed 14 years ago by michael.himmelsbach@…

I did not find a config.log, but in my macports.conf I found that I had recently enabled the use of ccache (ie, it contained "configureccache yes"). Setting "configureccache no" and doing a "port clean/configure/build/install imagemagick" then worked for me. I am up to date now, which also means that I will never use ccache again. Or is this a MacPorts-only ccache problem?

neverpanic, have you tried disabling ccache for MacPorts? This worked for me, and as I can see from your config.log in line 12929 (CC= ccache /usr/bin/gcc-4.2 -std=gnu99 -std=gnu99), you also have ccache enabled for building ImageMagick.

comment:7 Changed 14 years ago by neverpanic (Clemens Lang)

Yes I have and it did work, but maybe we can still get to the bottom of this or at least add a message that building ImageMagick with ccache will fail.

comment:8 Changed 14 years ago by michael.himmelsbach@…

Just a note: Building ImageMagick with ccache will probably only fail if another version of it was build with ccache before. If I find some time I will clear my ccache cache and see if it works then.

Same problem here too. "sudo ccache -C" followed by "port clean/upgrade imagemagick" failed with the same error. Disabling ccache completely followed by "port clean/upgrade imagemagick" worked fine.

comment:10 Changed 14 years ago by ryandesign (Ryan Carsten Schmidt)

Hmm. I had never used ccache before, but I've now installed it and configured MacPorts to use it, and ImageMagick still built fine for me.

First it failed in the same way for me as described above. It looks like the omp_throttle(1) macro was not pre-processed and was not expanded. Therefore the compiler chokes on the unknown directive.

But it works now with a clean ccache. My guess is that ccache was unable to detect changes for whatever reason and used old pre-processed input (old headers?) from the cache.

Has duplicate #27873. I guess I should disable ccache for ImageMagick.

Replying to michael.himmelsbach@…:

Setting the CCACHE_CPP2 environment variable changes the preprocessing behaviour making it compatible with ImageMagick. Not all ccache performance is lost. More information on usage at: http://workin.gs/compiling-imagemagick-ccache and on the explanation of the behaviour at: http://ccache.samba.org/manual.html#_environment_variables . I tested this on SLES 11.1 x86_64 , though.
