Erlang (all versions) doesn't package with ports-gcc-8, because:
- WxWidgets is built with headers made for ports-gcc-8, with
C++14 as the standard C++ version.
- Erlang requires WxWidgets but uses base-gcc, and during
configuration, it indeed outputs in $WRKSRC/lib/wx/config.log:
"/usr/local/include/wx-3.0/wx/strvararg.h:25:27: error:"
"type_traits: No such file or directory"
AFAIK base-gcc wants
- Meanwhile, it just builds without Wx, the issue appears when
packaging, because the Wx related files are not present.
It should have been easy if CHOSEN_COMPILER wasn't "irrelevant",
and if we were able to define it, but it would break the build on
clang archs.
What i'm proposing here is to bypass CHOSEN_COMPILER for !clang
arches. It unbreaks the packaging and ensures that WANTLIB is
proper, calling egcc/++ directly seems a bit too rough though.
It has been tested against Erlang 16 and 18, as my partial bulk
is still ongoing, i don't have resources to try them all.
Charlène.
