py24-scipy, py25-scipy @0.11.0: build fails when python24/python25 was built with ccache

[ryandesign (Ryan Carsten Schmidt)]

Building py24-scipy or py25-scipy fails, but py26-scipy and py27-scipy build fine.

[skymoo (Adam Mercer)]

Personally I don't run python24 and python25 as they are unsupported upstream, patches are welcome.

Somehow it's putting two compilers into the command line:

/opt/local/bin/g++-mp-4.5 /usr/bin/clang -isysroot / -L/opt/local/lib -bundle -undefined dynamic_lookup build/temp.macosx-10.8-fat-2.5/scipy/interpolate/src/_interpolate.o -Lbuild/temp.macosx-10.8-fat-2.5 -o build/lib.macosx-10.8-fat-2.5/scipy/interpolate/_interpolate.so

How is that command being constructed? That doesn't seem like the kind of problem you'd see from a too-old python version.

Also, the buildslaves don't have this problem, as there are binaries for the current version of py25-scipy and py24-scipy.

Thanks, that gave me a point to start. The two compilers in the command made me think of a ccache problem, where someone is not quoting $CC or $CXX properly, but using "configure.ccache no" in py-scipy did not help. It turns out the choice of whether to use ccache is baked into python24 and python25:

/opt/local/lib/python2.4/config/Makefile:CC=		ccache /usr/bin/clang
/opt/local/lib/python2.4/config/Makefile:CONFIG_ARGS=	'--prefix=/opt/local' '--disable-dependency-tracking' '--with-cxx=/usr/bin/clang++' '--enable-shared' '--mandir=/opt/local/share/man' '--without-readline' '--disable-tk' '--enable-ipv6' '--disable-toolbox-glue' '--enable-universalsdk=/' 'CC=ccache /usr/bin/clang' 'CFLAGS=-pipe -O2  ' 'CPPFLAGS=-I/opt/local/include -D__DARWIN_UNIX03' 'LDFLAGS=-L/opt/local/lib  '

/opt/local/lib/python2.5/config/Makefile:CC=		ccache /usr/bin/clang
/opt/local/lib/python2.5/config/Makefile:CXX=		ccache /usr/bin/clang++
/opt/local/lib/python2.5/config/Makefile:CONFIG_ARGS=	 '--prefix=/opt/local' '--disable-dependency-tracking' '--enable-shared' '--enable-framework=/opt/local/Library/Frameworks' '--mandir=/opt/local/share/man' '--enable-ipv6' '--with-cxx=/usr/bin/clang++' '--enable-universalsdk=/' 'CC=ccache /usr/bin/clang' 'CFLAGS=-pipe -O2  ' 'LDFLAGS=-L/opt/local/lib  ' 'CPPFLAGS=-I/opt/local/include -D_DARWIN_C_SOURCE'

python26 and python27 don't have this.

Rebuilding python24 and python25 with configure.ccache disabled fixed the py24-scipy and py25-scipy build, but of course it would be nice to allow python24 and python25 to have been built with ccache.

Closing this now that py24 and py25 versions of scipy are gone.
