graphviz: error: C compiler cannot create executables

[mrkapqa]

Hello,

on 10.7.5 port mpv failed at configuring graphviz.

Please see attachment,

Thanks.

[reneeotten (Renee Otten)]

is this failure with mpv any different than the other Trac ticket you reported?

thanks,

i could not tell,

however, graphviz also fails for port ffmpeg.

Replying to reneeotten:

I see no similarity with that ticket.

What I see in the log is what appears to be something fundamentally broken about either the Xcode installation or the compiler, I don't know; I don't recall seeing this before:

Has duplicate #64258.

Googling the error message, I found this:

See if any of the suggestions there help, or try your own search for the error message.

See also #56336 for possible suggestions.

thanks, seem to have resolved this issue for ffmpeg by re-installing, xcode 4.6.3 for lion, command line tools for lion april 2013, and latest macports.pkg for lion.

there seem however other factors included for mpv which iam not able to resolve atm, so please close this ticket.

Reinstalling MacPorts should not have been necessary but I'm glad you got it working.
