I'm getting back to you after (some vacations and) having compared
linaro's latest toolchain to the one I built.
Linaro provides a sysroot-package which does not contain
c++-header-files. Instead they are located in the gcc-package, as in
my package, in
<target>/include/c++/<gcc-version>/
I'm unable to convince clang(++) to include this search-dir using any
combination of the following options with variations on the path name.
--gcc-toolchain=
-B
--sysroot=
sysroot works a little bit, but only for c-include which are located in
<sysroot-dir>/usr/include.
Using gcc-linaro-5.3-2016.02-x86_64_aarch64-elf I would highly
appreciate an example of how to invoke clang++ for cross-compilation
with this gcc and its includes?
My current try is:
TARGET=aarch64-elf \
GCC_ROOT=~/Downloads/gcc-linaro-5.3-2016.02-x86_64_aarch64-elf \
~/devel/upstream/build/bin/clang++ \
-v \
--target=$TARGET \
--gcc-toolchain=$GCC_ROOT/$TARGET \
--sysroot=$GCC_ROOT/$TARGET/sysroot \
-nostdlib \
-o testCCompiler.cpp.obj -c \
-std=c++11 \
test.cpp
test.cpp is empty except #include <cstdint> which it doesn't find.
Linaro's gcc has all include paths in its search list.
Thanks in advance for any help,
--
Patrick.
