[cdt-dev] -fPIC option for Shared Libraries (64-bit Linux)
|
Hi!
Can somebody test the building shared libraries from Eclipse without -fPIC
parameter on any Linux x86_64?
On my machine (openSUSE 11.0 x86_64) gcc 4.3 can't build shared libraries:
make all
Building file: ../testlib.c
Invoking: GCC C Compiler
gcc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"testlib.d"
-MT"testlib.d"
-o"testlib.o" "../testlib.c"
Finished building: ../testlib.c
Building target: libtestlib.so
Invoking: GCC C Linker
gcc -shared -o"libtestlib.so" ./testlib.o
/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld:
./testlib.o: relocation R_X86_64_32 against `a local symbol' can not be
used
when making a shared object; recompile with -fPIC
./testlib.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [libtestlib.so] Error 1
Interesting, that on 32-bit openSUSE 11.0 x86 gcc 4.3 compiles shared
libraries without problems...
Please, see also https://bugs.eclipse.org/bugs/show_bug.cgi?id=256763
Best regards,
Andrey.
