- update from Fedora 6.2.1-2
but I haven't tested it yet.
It seems it helped. The devtoolset-6-gcc-6.2.1-3.el7 can be rebuilt using itself. Works with devtoolset-6-gcc-6.2.1-3.1.el7.aarch64 VERIFIED Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://rhn.redhat.com/errata/RHBA-2016-2734.html |
QE reported that a rebuild of devtoolset-6-gcc-6.2.1-2.el7 on aarch64 failed with ../../../libcpp/lex.c:754:22: fatal error: arm_neon.h: No such file or directory Yet devtoolset-6-gcc-6.2.1-2.el7.aarch64.rpm built in brew just fine. The problem is that when devtoolset-6-build is installed, the 'scl' macro is defined, so in gcc.spec file we do %{?scl:PATH=%{_bindir}${PATH:+:${PATH}}} so PATH contains DTS6. This also changes where we look for #include <...>: [...] /usr/lib/gcc/aarch64-redhat-linux/4.8.5/include vs. [...] /opt/rh/devtoolset-6/root/usr/lib/gcc/aarch64-redhat-linux/6.2.1/include But arm_neon.h is only installed with system gcc, where this was fixed in https://bugzilla.redhat.com/show_bug.cgi?id=1007490, and not with DTS6 gcc.
