It seems languages other than C are disabled for bare metal
builds. You could try searching for cc.ini in your
crosstool-ng installation and commenting out the line
if ! BARE_METAL
and
endif # ! BARE_METAL
Good to know. I'll prepare a patch
( I'm currently implementing cross-native builds for
crosstool-NG
anyway)
Just tried again with crosstools-ng 1.19.0. I commented out
the appropriate lines in my cc.ini file, but the build failed
with...
" The following requested languages could not be built: d "
... in the build.log file.
Also, the instructions here
(http://gdcproject.org/wiki/Cross%20Compiler/crosstool-NG) say:
"If druntime & phobos do not yet compile for your target you
can disable them:
Start ct-ng menuconfig, go to "C compiler" and add
"--disable-libphobos" to "Core gcc extra config" and "gcc
extra config". "
While the "Core gcc extra config" option exists, "gcc extra
config" does not.
The quest continues...
Thinking about this a little more, I figured the only way GCC
would not no about D is if the GCC sources were not
patched...and sure enough, I had crosstools pointing to the
wrong folder. My mistake.
I was finally able to build a GDC cross compiler using GCC 4.8.2,
the GDC 4.8 branch, and crosstools-ng 1.19.0. However, I found
the following errors in the instructions located here
(http://gdcproject.org/wiki/Cross%20Compiler/crosstool-NG)
1. The "Other Languages" option does not appear for a bare metal
build. You must modify the cc.ini file to make it available per
jerro's insructions above. Thanks jerro
2. The "Core gcc extra config" option exists, but the "gcc extra
config" does not. It doesn't appear to be necessary, but I have
yet to test this toolchain.
3. The "Paths and misc options, Local tarballs directory" option
does not seem to be correct. For me, I had to go to "C Compiler"
-> "gcc version" and choose "Custom gcc" and point crosstools-ng
to the folder containing the merged GCC/GDC source code.
I hope this information is useful to someone.
