Currently we have a problem in our cross compiler since we use
/usr/include/c++ to be default gxx-include-dir and then expect
the patch we did to do the relocation w.r.t. sysroot however it
does not quite work so and we end up gxx-include-dirs not respecting
sysroot. A small test case would be
tst-unique4.cc
and it would fails like
tst-unique4.cc:1:18: fatal error: cstdio: No such file or directory
compilation terminated.
weather we use --sysroot or not it does not matter
arm-oe-linux-gnueabi-g++ -S tst-unique4.cc
--sysroot=/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm
failed in same way.
so we redo the GPLUSPLUS_INCLUDE_DIR_with_sysroot.patch based on upstream
submitted patch which tries to relocate the gxx-include-dir and to
achieve the relocation it has to be specified w.r.t to --with-sysroot
directory. e.g.
--with-sysroot=${SYSROOT}
--with-gxx-include-dir=${SYSROOT}/usr/include/c++
if we configure gcc like above then it becomes relocatable when
we run the compiler and specify --sysroot=<blah> then g++ will search
for gxx-headers under <blah>/usr/include/c++
if sysroot is not defined then it will use the default sysroot
and gxx-include-dir will be w.r.t. default sysroot.
Tested on qemuarm
/arm-oe-linux-gnueabi-g++ -S tst-unique4.cc
--sysroot=/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm
-v
...
/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm/usr/include/c++
/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm/usr/include/c++/arm-oe-linux-gnueabi
/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm/usr/include/c++/backward
...
and if I now change --sysroot to something else
/arm-oe-linux-gnueabi-g++ -S tst-unique4.cc
--sysroot=/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm4
-v
...
ignoring nonexistent directory
"/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm4/usr/include/c++"
ignoring nonexistent directory
"/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm4/usr/include/c++/arm-oe-linux-gnueabi"
ignoring nonexistent directory
"/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm4/usr/include/c++/backward"
...
See now its looking for them in 'qemuarm4' sysroot
