ld: warning: in /opt/local/lib/libcppunit.dylib, missing required architecture x86_64 in file

[blueduck@…]

If I try to compile some programm with cppunit I got the error above.

Seems the libcppunit.dylib was not compiled for 64 bit, when installed by mac ports.

lipo -info /opt/local/lib/libcppunit.dylib Architectures in the fat file: /opt/local/lib/libcppunit.dylib are: ppc7400 i386

Please remember to cc the maintainer, and put the name of the port in the Port field. As per the ticket guidelines, the High priority is reserved for the use of MacPorts team members.

Please show the output of

port -v installed cppunit

and the universal_archs line from your macports.conf.

Sorry for the inconvenience.

$ port -v installed cppunit
The following ports are currently installed:
  cppunit @1.12.1_0+universal (active) platform='darwin 10' archs='i386 ppc'

cat /opt/local/etc/macports/macports.conf
...
# machine architectures
universal_archs		ppc i386

Hey,

what means "invalid" in this case? Did I misconfugured something? Does it work for you?

How I could compile cppunit .cpp files?

Thanks in advance, Stefano

Now it works for me too.

I changed some settings in macports.conf

# MACOSX_DEPLOYMENT_TARGET
universal_target	10.5 -> universal_target	10.6

# the SDK "sysroot" to use 
universal_sysroot	/Developer/SDKs/MacOSX10.5.sdk -> universal_sysroot	/Developer/SDKs/MacOSX10.6.sdk 

# machine architectures
universal_archs		ppc i386 -> universal_archs		i386 x86_64

and compile cppunit again.

Thanks for the hidden hints. Stefano

Right, MacPorts did exactly what it was configured to do with universal_archs. FYI, universal_target and universal_sysroot no longer do anything.
