Dear all,
I've just implemented and committed a default +universal variant
for configure-based ports. There's been some heat about +universal
recently and I did not want every port to define the same code over
and over.
This variant is more or less equivalent to:
variant universal {
configure.args-append "--disable-dependency-tracking"
configure.env-append CFLAGS="-isysroot /Developer/SDKs/
MacOSX10.4u.sdk -arch i386 -arch ppc" LDFLAGS="-arch i386 -arch ppc"
}
As I just pointed out to Elias Pipping on the bug-libtool list, if a c
++ compiler is required then the CXXFLAGS also need to be set.
Also, if you want stuff using libtool to build universal this will
only work with libtool-1.5.22 or later.
If you want stuff to have a chance of building with older versions of
libtool then you have to do pretty things like:
CC='gcc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch
i386' CXX='g++ -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -
arch i386' CXXCPP='g++ -E' CPP='gcc -E'
And then there is the following bug that I have not fixed yet:
-isysroot will chose the wrong library if there exists a .la file for
the lib in /usr/lib but not in the SDK.
There are probably other bugs that I have yet to fix but have also
simply forgotten, libtool not using a bug tracking system has its
advantages, I guess :-p
