[Bug gcov-profile/30258] New: [4.1.0] undefined reference to `__gcov_one_value_profiler'

Hi everyone,

while running the regression tests for a x86_64 cross-toolchain build under
Cygwin lots of profiler tests went FAIL or UNRESOLVED. The first FAILed while
generating inliner-1.x01:

/usr/local/build-root/build-sles10-64/x86_64-pc-linux-gcc/gcc/xgcc
-B/usr/local/build-root/build-sles10-64/x86_64-pc-linux-gcc/gcc/
/usr/src/gcc-4.1.0/gcc/testsuite/gcc.dg/tree-prof/inliner-1.c -O2
-fdump-tree-optimized -fprofile-generate -fno-show-column -lm -o
/usr/local/build-root/build-sles10-64/x86_64-pc-linux-gcc/gcc/testsuite/inliner-1.x01
inliner-1.o: In function `hot_function':
inliner-1.c:(.text+0x39): undefined reference to `__gcov_one_value_profiler'
inliner-1.o: In function `cold_function':
inliner-1.c:(.text+0x99): undefined reference to `__gcov_one_value_profiler'
inliner-1.o: In function `main':
inliner-1.c:(.text+0x115): undefined reference to `__gcov_one_value_profiler'
inliner-1.c:(.text+0x164): undefined reference to `__gcov_one_value_profiler'
collect2: ld returned 1 exit status

The second type of failure is while retriving the profiler data: file
update-cunroll-2.gcda does not exist,  -fprofile-generate.

gcc was configured with following options:
./configure --target= x86_64-pc-linux --prefix= 
/usr/local/sles-x86_64
--enable-languages=c,c++ --enable-shared --enable-threads=posix 

--disable-multilib --enable-__cxa_atexit

Any idea ?

Hmm, I think this means you are linking against the wrong version of libgcov.

I finally found out that the "inhibit_libc" flag was set during the gcc
compilation because I'm building a cross-compiler without sysroot and headers.
As a consequence _gcov_* functions aren't defined in libgcov.
