Bugzilla Bug 75272

After building mono, and moving onto mcs, I came across the following build
error:

make[2]: Entering directory
`/var/tmp/portage/mono-1.0.5-r3/work/mono-1.0.5/web'make[2]: Nothing to be done
for `all'.
make[2]: Leaving directory `/var/tmp/portage/mono-1.0.5-r3/work/mono-1.0.5/web'

build/rules.make:77: build/platforms/powerpc-unknown-linux-gnu.make: No such
file or directory
make: *** No rule to make target
`build/platforms/powerpc-unknown-linux-gnu.make'.  Stop.

Indeed build/platforms/powerpc-unknown-linux-gnu.make doesn't exist - it should
just be build/platforms/linux.make.

The problem is in build/rules.make:

# Platform config

include $(topdir)/build/platforms/$(PLATFORM).make

For some reason $(PLATFORM).make seems to be overridden with
'powerpc-unknown-linux-gnu'.

Very odd indeed. Is PLATFORM defined for you from somewhere?

As a possible solution, try to do "export PLATFORM="linux"" somewhere in the ebuild to override this before the mcs make is called.

adding, export PLATFORM="linux" seems to set the platform right, and works - as
does adding make PLATFORM=linux || die for the mcs compilation.

It's still very peculiar. I've tried dumping env just before the "make || die"
as well, but there's no evidence of PLATFORM anywhere.

Very odd indeed. I've commited fixed versions for -r2 and -r3, please give one
of those a shot to confirm this fixes things.

Thanks latexer, it finishes the compile now, but we also need to set
PLATFORM=linux when calling make in src_install() or else it won't find
linux.make again.

With that fix in (ie add make PLATFORM=linux in src_install()) it works fine.

Hi there Peter,

i'm afraid that it still happens with -r3. I had to repair it manually in order to get the ebuild merged.

I've added the fix in the second spot on Jan 2nd, can you please test and
confirm it is working? Thanks.

Tested, confirmed fixed. Thanks Peter.

Ok, marking FIXED. Thanks.
