Description Vasiliy 2017-02-28 15:19:03 UTC

protobuf-c 1.0.2-r1 and 1.1.1 doesn't compile with gcc-4.6, gcc-4.9 works fine.
Compiler version check in ebuild could fix.

Error output follows:
/usr/lib/gcc/x86_64-pc-linux-gnu/4.6.4/../../../../lib64/libprotobuf.so: undefined reference to `std::__throw_out_of_range_fmt(char const*, ...)@GLIBCXX_3.4.20'


Reproducible: Always

Steps to Reproduce:
1. select gcc-4.6.4 profile
2. emerge protobuf-c

Actual Results:  
Compile phase failure.

Expected Results:  
Successful merge.

# Those old versions of GCC are no longer really supported and are not
# suitable for use as a system-wide compiler. Using them can result
# in build failures (and possible breakage) for many packages.
#
# If you still use one of these as your system compiler, please upgrade
# and switch the compiler ASAP. If you need them for a specific (isolated)
# use case, feel free to unmask them on your system.
