Could it be missing --with-float= or --with-fpu configure
flag perhaps? I'm just finishing up a few changes to the
build scripts that turn off building phobos. Can add another
check for extra configure flags to be set per-target.
Iain.
Yes, it's likely one of these. I can't test this right now,
but the simplest way is running the ubuntu
arm-linux-gnueabihf-gcc -v and copy the configuration. We
should generally use exactly the same configuration as ubuntu
to get reliable results (Otherwise the binutils/libc we use
from the distribution might be not compatible with the
compiler/libgcc/libstdc++,... libraries we build).
I guess explore.dgnu.org uses the same configuration and it
uses:

Yeah, however 90% of that is unused by us. I've added a
BUILD_CONFIGURE_FLAGS var to the buildci.sh script.
https://github.com/D-Programming-GDC/buildbot-gdc/commit/47f8c7267682f19b3e1ce2afa49034217413451a#diff-711e8a244e68a7a465f29a18e33a22c3R34
Can add a case for armhf and set --with-fpu= later and see if
that gets us further.
Iain.
Folks, I am eagerly following the work on GDC related to
AARCH64/linux. I am attempting to duplicate results I see here:
https://buildbot.dgnu.org/#/builders/2/builds/51
build 51 looks as if it succeeds. In following the configure
logs for build 51, I see a buildci.sh script gets run. I would
love to know what gcc configure command gets run. Are the build
artifacts available for download? In particular, the config.log
would be helpful. In my own previous attempts to build on
AARCH64, I hit "not implemented" build error in math.d on the
ieeeFlags, and would also probably hit "unsupported platform".
It seems that my platform doesn't resolve that it is "arm". And
so I understand how the gdc development process works, will
platform support fixes get back ported into older branches of
GDC? Your build is on master, but my question is, are AARCH64
support patches backported into the gdc-7 or gdc-6? It seems
like yes, but I haven't gone through the branches in detail yet.
Thank you for the ARM support!
