Re: Compiling gccxml

Hi Brett,

As a first attempt I would ask you to try out if maybe the slc4 version would run for you. gccxml is used as an executable in the dictionary building process and as such simply called on the system level (no include, linking is involved). If the execution, just calling the "gccxml" executable, works fine on your distribution there should not be any problems with it. You may get the binaries either from afs

/afs/cern.ch/sw/lcg/external/gccxml/0.6.0_patch3/

or

http://service-spi.web.cern.ch/service-spi/external/distribution/

Otherwise you have already gone the right way with applying patch2 before the build and patch1/3 after the build. For the LCG s/w we have used cmake 1.8.3 maybe try this version for the build. For Mac OSX we have built the binary with gcc 4.0.1 so it should be possible.

Apologies for the inconveniences, building the patch version of gccxml is not always trivial. We are currently moving back to version which is available from the CVS gccxml repository, which should be available soon.

Cheers
