Description (last modified by ryandesign (Ryan Carsten Schmidt))
Building a 64-bit binary with g++ 4.5.2 fails with linking error (Core2Duo, OS X 10.5.8, MacPorts 1.9.2, gcc 4.5.2_0)
ld warning: in /opt/local/lib/gcc45/libstdc++.dylib, file is not of required architecture ld warning: in /opt/local/lib/gcc45/libgcc_ext.10.5.dylib, missing required architecture x86_64 in file ld warning: in /opt/local/lib/gcc45/gcc/i386-apple-darwin9/4.5.2/libgcc.a, file is not of required architecture
C++ example code for testing from http://en.literateprograms.org/Sieve_of_Eratosthenes_%28C_Plus_Plus%29
32-bit version from above example builds well:

Replying to jmr@…:
Did you install gcc45 with +universal? If not, you're not expected to be able to build both 32- and 64-bit. What do you have build_arch set to? If it's x86_64 and you didn't use +universal then the port has built for the wrong arch for some reason, but if it's i386 then this is not a bug.
Found no build_arch setting in my macport.conf from 2007. Seems the default is then i386 on leopard. Unfortunately didn't install gcc45 with +universal.
Updated the port now with "sudo port upgrade --enforce-variants gcc45 +universal" and got this error:
---> Fetching gmp ---> Verifying checksum(s) for gmp ---> Extracting gmp ---> Applying patches to gmp ---> Configuring gmp ---> Building gmp ---> Staging gmp into destroot ---> Installing gmp @5.0.1_0+universal ---> Deactivating gmp @5.0.1_0 ---> Activating gmp @5.0.1_0+universal ---> Cleaning gmp ---> Computing dependencies for gcc45 Error: Cannot install gcc45 for the arch(s) 'i386 x86_64' because Error: its dependency gmp does not build for the required arch(s) by default Error: and the configured universal_archs 'i386 ppc' are not sufficient. Error: Unable to upgrade port: architecture mismatch To report a bug, see <http://guide.macports.org/#project.tickets>
Workaround:
Adding "universal_archs x86_64 i386" to macports.conf and a second upgrade run with "+universal" did resolve this. Linking 64-bit with gcc45 works well now!
Thanks to jmr for helping, sorry for reporting this as bug.
