[Bug bootstrap/41818] New: Error building cross compiler caused by changing LD_LIBRARY_PATH environment variable in Makefile

[denis dot onischenko at gmail dot com]

The following error occurs when compiling "x86_64 to powerpc64"
cross compiler, as soon as the libgcc_s.so.1 has appeared in obj/gcc
directory:

...
# Now that we have built all the objects, we need to copy

It seems that host cc1 executable tries to load target libgcc_s.so.1
from obj/gcc directory, rather than host libgcc_s.so.1 from /lib.

I have successfully build the cross-compiler with overriden RPATH_ENVVAR
variable, as following:

make RPATH_ENVVAR=MY_LD_LIBRARY_PATH

 So error was indeed caused by changing LD_LIBRARY_PATH environment variable
during the build

@if gcc-bootstrap
        $(RPATH_ENVVAR)=`echo "$(TARGET_LIB_PATH)$$$(RPATH_ENVVAR)" | sed
's,::*,:,g;s,^:*,,;s,:*$$,,'`; export $(RPATH_ENVVAR); \
@endif gcc-bootstrap


That is only happens when doing a native bootstrap and never when doing a cross
build.

Actually, wait:
        $(RPATH_ENVVAR)=`echo
"$(HOST_LIB_PATH)$(TARGET_LIB_PATH)$$$(RPATH_ENVVAR)" | sed
's,::*,:,g;s,^:*,,;s,:*$$,,'`; export $(RPATH_ENVVAR);

For BASE_TARGET_EXPORTS.

------- Comment #4 from jocke at vmlinux dot org  2010-01-06 13:53 -------
I can confirm this issue while building an armeb-unknown-uclibcgnueabi
(big-endian) cross toolchain on i686 (Ubuntu 9.10 32-bit) using crosstool-NG. 
However, I cannot replicate it on any host running x86_64 (Ubuntu 9.04 or 9.10,
64-bit).  Also, when building a arm-unknown-uclibcgnueabi (little-endian) this
bug is not triggered.  Maybe that helps.

Some of the messages in the official mailing list archive related to this issue
have somehow been lost (?),
http://gcc.gnu.org/ml/gcc-bugs/2009-10/msg02122.html (see the thread view).  I
found
http://old.nabble.com/Re:-Error-when-building-cross-compiler-td25755999.html
where Kai Ruottu gave some interesting insight.

The bug can be worked around by adding the --disable-shared configure option to
the last (final) stage in the compiler build.

I have successfuly compiled cross compiler with this patch. gcc revision is
155559. host is x86_64-unknown-linux-gnu, target is
powerpc64-unknown-linux-gnu.

Yep, works for me too, using crosstool-NG to build an
armeb-unknown-linux-uclibcgnueabi for i686 host. Thanks Ralf!

I encountered that issue with gcc 4.3.4 on the following target:
mips-unknown-linux-uclibc. I'm currently confirming with gcc 4.3.5. If it still
happen, would it be worth pulling to the 4.3 branch ?

ok, 3.4.5, same target is bad too:

Can you please confirm that the patch from comment #8 fixes the issue for you
on the 4.3 (and maybe also 4.4) branch?  I'd propose the backport on
gcc-patches then.  Thanks.
