Dear listmembers,
maybe offtopic, but maybe someone could give me a pointer where to ask / what
to do. I upgraded my good old SuSE 9.3 to gcc 4.1.2, I made the kernel 2.6.11
build with that compiler (was some work) and now I finally managed to make
glibc-2.3.4-23.9 from the 9.3 distribution build given this combination of
gcc / kernel - yes, well, with two issues:
1.) /* major issue IMHO */
one test fails, tst-signal1.c gives the output
(tst-signal1.out):
sending the signal now
sigwait returned with Interrupted system call (4)
thread joined?!
child wasn't signalled
The "child wasn't signalled message breaks the build, does someone has an idea
what could be the root cause for this issue? Should one build in single user
mode / any special precautions for glibc?
2.) /* minor issue IMHO but still not nice */
one of the math test fails too due to insufficient precision (test-float.out):
testing float (without inline functions)
Failure: Test: Real part of: cacosh (-2 - 3 i) ==
-1.9833870299165354323470769028940395 + 2.1414491111159960199416055713254211

Test suite completed:
2599 test cases plus 2384 tests for exception flags executed.
2 errors occurred.
I "glued" plasters over both of the failures, IMHO the second failure might be
a rounding issue at 10^-6 error size - not that bad. The first error makes me
headaches, but maybe someone on the list can remove it for me :-):-)
Is there anything with regard to the CFLAGS that stem from rpm that should be
obeyed / taken care for? _Should_ one build as super user?
Thank you very much,
take care
