#32642 closed defect

ImageMagick's PC files contain -fopenmp which makes GCC 4.0 fail — at Version 1

Description (last modified by ryandesign (Ryan Carsten Schmidt))

When I try to compile GNU Emacs 24.0.92 with GCC 4.0 on Mac OS X 10.6.8 the configure script stops prematurely with: 

checking for libXaw... configure: error: Lucid toolkit requires X11/Xaw include files

which config.log explains: 

cc1: error: unrecognized command line option "-fopenmp"

This too modern switch is introduce from any of these PC files: 

/opt/local/lib/pkgconfig/ImageMagick.pc:Cflags: -I${includedir} -fopenmp
/opt/local/lib/pkgconfig/MagickCore.pc:Cflags: -I${includedir} -fopenmp
/opt/local/lib/pkgconfig/MagickWand.pc:Cflags: -I${includedir} -fopenmp
/opt/local/lib/pkgconfig/Wand.pc:Cflags: -I${includedir} -fopenmp

One of them is asked by configure: 

config.log:configure:10891: result: -fopenmp -I/opt/local/include/ImageMagick

and than this compiler option is used. This is similar to tickets #15945 and #24944.

What about setting up a directory of backward compatible PC files without this -fopenmp switch?

My work-around is to copy a modified version of /opt/local/lib/pkgconfig/ImageMagick.pc into the root directory and modify PKG_CONFIG_PATH to contain .´´.

That seems fraught... Wouldn't implementing #15945/#24944 (providing an openmp variant you could deselect) be the best solution?
