Bug 512982 – net-libs/webkit-gtk-2.4.3 with sys-devel/gcc-4.8.2 - You need at least GCC 4.7.x or Clang >= 3.3 for C++11-specific compiler flags

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Henry Wertz 2014-06-11 16:15:56 UTC]

Summary says it -- webkit-gtk-2.4.3 fails to build, saying it needs at least gcc-4.7.x to build, while I in fact have gcc-4.8.2-r1 installed:

"
>>> Running pre-merge checks for net-libs/webkit-gtk-2.4.3
 * ERROR: net-libs/webkit-gtk-2.4.3::gentoo failed (pretend phase):
 *   You need at least GCC 4.7.x or Clang >= 3.3 for C++11-specific compiler flags
 * 
 * Call stack:
"
.....
    I assume it is checking for *exactly* gcc-4.7.x?  Either that, or it's C++11 test fails against gcc-4.8.x.  

Reproducible: Always

Steps to Reproduce:
1. Install gcc-4.8.2-r1 (and remove gcc-4.7).
2) Go to install net-libs/webkit-gtk-2.4.3

I guess the die() message could use improvement. The test isn't about versions but about a specific feature.

[Comment 2 Pacho Ramos 2014-06-12 17:03:14 UTC]

The check is looking for the needed feature:
        if ! test-flag-CXX -std=c++11; then
                die "You need at least GCC 4.7.x or Clang >= 3.3 for C++11-specific compiler flags"
        fi

not for any specific version

The test looks ok to me, maybe something is strange in your gcc-4.8 build (or don't have it selected properly)

[Comment 4 Giuseppe Scaglione 2014-08-29 01:23:41 UTC]

I solved with gcc-config -f 
I hope it is of help.

Try:
gcc-config -f YourChoise.....

[Comment 5 Pacho Ramos 2014-10-03 10:42:40 UTC]

I can't see anything wrong in our test
