As per the link that was mentioned several times in your output, please ​clean, try again, and attach the main.log file, which was also mentioned several times in your output.

By the way, there is no gcc port, and gcc48 does not have a gfortran variant.

Could be related to #40439.

I've encountered this, when trying to install gcc47 +universal. This requires libgcc +universal, and the build of this fails. I did

sudo port selfupdate
sudo port uninstall libgcc
sudo port install libgcc +universal

This last yields:

In the log, I see:

Did you do that?

Now that you've pointed it out, I have. But this is going further down the rabbit-hole, since a response from the GCC people (assuming I reported it correctly, and it's not a dupe) will almost certainly involve further tinkering with the innards of MacPorts in ways only a ports developer/maintainer would be comfortable with ...

Sorry; here it is: ​http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58842

I had one reply, making some quite reasonable suggestions that I haven't yet had time to act on, and which --- as I expected --- require me to get my hands dirtier.

This was closed as "worksforme", so I doubt we will be getting much help from upstream here. Anyways, I recently ran into this error on my computer, too, so I will attach my own logs here next.

diff between the config.log posted upstream in gcc's bugzilla and the one that I posted here

[cooljeanius (Eric Gallager)]

I re-ran the gmp, libmpc, and mpfr testsuites as upstream instructed, and mpfr's testsuite failed (edit: same with libmpc), so I opened a separate issue for that: #42732 (edit: and #42733 for the other)

Anyways, once those are fixed, this should be fixed, too, but I will have to test to see for sure...

Edit: also, seeing as gcc depends on its dependencies being built properly (as shown here), it would probably be useful the testsuites of its dependencies were run automatically as part of the normal install process, so I opened a separate issue for that, as well: #42731

Has duplicates #41753, #42752, and #42940

[email.sachinarora@…]

was trying sudo port install gcc48 +universal but it would get stuck at building libgcc stage(gfortran not working)..so i tried this instead and it worked..

sudo port clean libgcc
sudo port -v install gcc48 +gfortran
sudo port select --set gcc mp-gcc48
hash gcc
gcc -v

[ryandesign (Ryan Carsten Schmidt)]

Looks like #30479 is a duplicate.
