Description aditya3098 2015-05-19 04:39:08 UTC
I recently upgraded to GCC 5.1 on my ~amd64 machine. I recompiled the entire world, as gcc5.1 was a major upgrade. I had an issue with a few packages, but because of the --keep-going flag I set on emerge, it was no problem, I simply looked at the emerge log to find out which packages failed. I managed to get most of them to compile later, but I have been stuck trying to compile media-gfx/iscan. 
The emerge keeps failing. Please see attachment. This is my first but report, tell me if I need to do something else or if this bug is in the wrong section.

Reproducible: Always

Steps to Reproduce:
1.Upgrade to gcc-5.1
2.emerge -av media-gfz/iscan
Actual Results:  
The emerge fails, and the program stays at its previous version

Expected Results:  
The program (media-gfx/iscan) should have successfully emerged.

Can anyone tell me if I provided sufficient info?
Comment 8 Mike Gilbert gentoo-dev 2015-05-29 00:42:48 UTC
@maintainer: I'm not sure this is gcc5 related. If it is, please block bug 536984.
Comment 9 aditya3098 2015-05-29 04:21:44 UTC
@Mike Do you mean you are able to compile or that I simply need to check with the other gcc? If the second, then I did, and it worked.
Comment 10 Ryan Hill (RETIRED) gentoo-dev 2015-05-31 03:19:17 UTC
It's due to this garbage:
  65 #  Transitionary check for the C++ ABI while we are switching provided
  66 #  binaries from gcc-3.[23] to gcc-3.4 or later.  Currently gcc-3.[23]
  67 #  is still the official compiler version to use, but experimental bi-
  68 #  naries are released with a ".c2" suffix.
  69 #  The CXX_ABI for gcc-3.[23] is 102, btw.
  70 #  Note that the PACKAGE_RELEASE for the gcc-3.4 or later packages has
  71 #  to be larger than that for the gcc-3.[23] packages (as long as both
  72 #  are distributed) for smooth upgrade paths.
  74 if test "$GXX" = "yes"; then
  75     AC_MSG_CHECKING([C++ ABI version])
  76     CXX_ABI="`$CXX -E -dM - < /dev/null | $AWK '/GXX_ABI/ { print $3 }'`"
  77     AC_MSG_RESULT([$CXX_ABI])
  78     if test x"$CXX_ABI" = x1002; then
  79         PACKAGE_CXX_ABI=".c2"
  80     else
  81         PACKAGE_CXX_ABI=""
  82     fi
  84 fi

$ g++-5.1.0 -E -dM - < /dev/null | grep GXX
#define __GXX_ABI_VERSION 1008

and only the .c2 version of the libesmod lib is provided for x86_64.

Please runtime test this before applying.  Since this is a prebuilt binary it may not work correctly with the new C++ ABI.

Thanks rhill, nice work. Awaiting test run by aditya3098 and/or maintainer who is notable in his absence.
Comment 14 Adam Feldman gentoo-dev 2015-07-15 19:09:53 UTC
The g++ patch is included in the version bump (498524).
