For Sourcery Codebench toolchains the 'gcc -print-file-name' only returns
the proper sysroot directory when the proper architecture flags are
provided via '-m64 -march=' flags. These flags are provided via the
ptxdist platformconfig PTXCONF_TARGET_EXTRA_CFLAGS setting.
These flags therefore also need to be passed to GCC here.

I think ptxd_get_ptxconf should work here. And I think you should use
PTXCONF_TARGET_EXTRA_CFLAGS and PTXCONF_TARGET_EXTRA_CPPFLAGS.

Busybox make is not properly called in case:
* compiler name tuple does not match target tuple (as used in multilib
compilers, for example: i686-pc-linux-gnu-gcc can compile for
x86_64-unknown-linux-gnu targets. To solve this the 'SUBARCH' need to be
set)
* CONFIG_EXTRA_CFLAGS need to e set to select the proper sysroot to
compile against in busybox
* LDFLAGS to link against the proper sysroot.

IIRC I tried this and that the build started failing if I added all flags.
Will look into it again.
Thanks.

This results in:
-----------------------
target: busybox.prepare
-----------------------
make: invalid option -- '6'
make: invalid option -- '4'
make: invalid option -- '/'
make: invalid option -- '/'
Usage: make [options] [target] ...
Options:
etc.
It seems I have to stick with the bare minimal options I can set
here... Or any other ideas?
Kind regards,
Remy

Don't set any flags in BUSYBOX_MAKE_OPT. From what I can tell, the current
busybox Makefile uses CFLAGS, CPPFLAGS and LDFLAGS from the environment.
Try something like this (untested):
BUSYBOX_MAKE_OPT := \
ARCH=$(PTXCONF_ARCH_STRING) \
SUBARCH=$(PTXCONF_ARCH_STRING) \
CROSS_COMPILE=$(COMPILER_PREFIX) \
HOSTCC=$(HOSTCC)
BUSYBOX_MAKE_ENV := \
$(CROSS_ENV) \
CFLAGS="$(CROSS_CFLAGS) -I$(KERNEL_HEADERS_INCLUDE_DIR)"
SKIP_STRIP=y
BUSYBOX_INSTAL_ENV := \
$(BUSYBOX_MAKE_ENV)
and remove the PTXCONF_BUSYBOX_RFKILL stuff. The extra "-I" unconditionally
does not hurt.
Michael

This seems to work properly. Thanks.

It is assumed by the makefiles that all dynamic linkers must be put in
/lib. This is however not true. Especially on multilib configurations this
information cannot be guessed. By looking in the sysroot of the compiler
toolchain the right paths can be found. Default the scripts already look
there, so remove the unneeded options.

No obvious issues but I need to do some more testing, to make sure it
doesn't break any other toolchains.

OK. Thanks.

Hi,
FYI: With these 5 patches (and a few unfinished architecture.in
patches I have here locally) I at least get the glibc and the dynamic
linkers installed in the right place and all binaries we used to be
compiled with the right flags.
Furthermore, I noticed that the extra flags are not passed properly to
all packages, so I expect to find more issues with multilib on X86.
So, since we need the multilib/x86_64 support I expect that in time
more patches will likely be posted to get this supported in ptxdist.
Kind regards,
Remy

Great. This has been a known issue for some time, but I don't have the
time to go through all the packages and fix it.

This link is always being generated and it is assumed that it must
always point to /lib/libdl.so.2.
But this script is not needed and points to the wrong location when a
multilib toolchain is being used where the dynamic linker must be in
/lib64

This should be:
CFLAGS = $(CPPFLAGS) -D_GNU_SOURCE -Wall -Wno-nonnull -Isrc/include $(CFLAGS)
CFLAGS is for C CXXFLAGS for C++ and CPPFLAGS in theory for the
preprocessor and therefore often used to pass flags for both.
And note the order.
And you should probably set:
LIBS = $(LDFLAGS) -lrt -lpthread
The flags should come first here.

Hmm, I knew that, not sure why I used CXXFLAGS...
Will fix it.

Will check that.
