Hi,
I'm working on adding Go (http://golang.org) to OpenWRT. Actually, I
already have it working.
The goals:
- Create gcc crosscompiler with the gccgo frontend which can be used to
compile a go project into a binary.
- Build and include libgo.so in the target image. libgo.so is the only
run-time requirement for binaries built with gccgo. ("go packages" that
are included in the project are compiled into the binary, afaik there's no
need for a packages feed providing go libs)
To achieve these I've added some directives in the OpenWRT makefiles an
menu config.
https://github.com/GeertJohan/openwrt-go/commit/ac3ad0dc738ed94bed82723b486566b23ea491d1
This all works fine, and I have go binaries running on the MikroTIK 750GL.
However, I would like to add/fix a two problems before I create and submit a patch.
GCC version
The gccgo frontend is only available in gcc 4.7.x (or higher). What would
be the proper way to force the user to use gcc 4.7.x (or higher) when
building with gccgo?
Can the "Build/install gccgo compiler?" option be greyed out until the
proper version of gcc is selected?
libgo.so depends on eglibc
I have the same "dependency" problem with libgo.so, it requires eglibc.
The default is uclibc. What would be the proper way to notify the user?
I don't want people having to figure out why their build fails when it can
be avoided.
Any thoughts on how to do this?
Do you see anything else that might need attention before submitting a
patch?
Best regards,
Geert-Johan Riemer
