MacPorts base fail to build for x86_64 on 10.6.8

[barracuda156]

It pulls from somewhere a wrong arch flag here:

Configure line:

./configure --prefix=/opt/x86_64 --build=x86_64-apple-darwin10 --with-applications-dir=/opt/x86_64/Applications --without-startupitems CC='gcc-4.2 -m64 -arch x86_64' CXX='g++-4.2 -m64 -arch x86_64'

UPD. It does build with ./configure --prefix=/opt/x86_64 --build=x86_64-apple-darwin10 --with-applications-dir=/opt/x86_64/Applications --without-startupitems CC=gcc-4.2 CXX=g++-4.2, but forces arch i386, unasked for.

Yeah, don't put flags in CC like that.

Yeah, don't put flags in CC like that.

With due respect, I disagree here, this is a) legit use and b) exactly required on 10.6.x to build Macports for Rosetta. But the ticket indeed can be closed anyway.

putting in m64 manually wrecks the arch flags for gcc. So it forces arch i386 to build as 64 bit, causing lipo to fail.

so you can’t do that.

Replying to barracuda156:

required on 10.6.x to build Macports for Rosetta.

I really doubt that given that CFLAGS and SHLIB_LDFLAGS are sufficient for all our universal builds.
