port install gcc46 +gfortran +universal (failed during build on Mac OS X 10.7 lion)

[annacegu@…]

Hi,

I am not able to build using the following command: port install gcc46 +gfortran +universal

This is on a recently purchased MacBook Pro, with OS X 10.7 lion.

This is part of the main.log file generated, it's too large to copy in its entirety: (/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_gcc46/gcc46/main.log)

:info:build make[6]: Entering directory `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_gcc46/gcc46/work/build/gcc'
:info:build collect2: ld terminated with signal 6 [Abort trap: 6]

Please help... I have tried compiling gcc & gfortran myself and it's an uphill battle... I would like it done by macports instead.

Regards, Anna.

Anna, there is nothing we can do for you at this point. MacOS 10.7.0 is buggy, what you see is a bug in the linker Apple provides with Lion. Until they post a fix in 10.7.1 (let's presume so), it is impossible to compile gcc 4.6.0 or gcc 4.6.1. Meanwhile, you've no choice but content you with gcc45…
