Bugzilla Bug 82836

When I try to emerge scumvm 0.7 I get the following error message:
Running ScummVM configure...
Looking for C++ compiler... g++
Checking for compiler version... tail: `-1' option is obsolete; use `-n 1' since this will be removed in the future
3.4.3-20050110, bad

The version of your compiler is not supported at this time
Please ensure you are using GCC 2.95.x or GCC 3.x

!!! ERROR: games-engines/scummvm-0.7.0 failed.
!!! Function src_compile, Line 53, Exitcode 1
!!! configure failed


Reproducible: Always
Steps to Reproduce:
1. emerge scumvm



Expected Results:  
I should accept the gcc-version, because it's gcc 3.x as mentioned...

reopen with the output of emerge --info

remerge gcc and try it again please.

I can do it again, but I already emerged gcc (and the complete toolchain) twice
 and I compiled over 300 different packages without problems.
(I recompile the wole system.)

what's the output of g++ -dumpversion

3.4.3-20050110

I think the configure script has a problem with the additional minus with the
timestamp.

yeah.  that's not right.  it should just be 3.4.3

But it's the first configure script that has this problem. Strange...

it's not an autoconf configure script.

What does this mean and what can we do now?

I remember that I had 2 version auf gcc3.4 installed: 3.4.3-r1 and
3.4.3.20050110
Maybe that is the reason, why it added the timestamp to the latest version.
I removed now all gcc's except the 20050110 and re-emerge now the 20050110.
Then I will try to emerge ScumVM and will tell you the result in 2 hours.

Looks like the gcc version detection code is broken in the configure script
provided by upstream.  I've patched it to work with the version you're getting.

resync in a bit and try it again.

I re-emerged gcc but nothing changed...
I have done a sync but it's not in the portage (mirror) yet.
I will try it tomorrow...

Now the configure script works without problems. Thank you for the patch.
