Description of problem: gcc should compile crtbeginT.o w/ fPIC on Intel 64 to avoid following problem - seen when using icc -fast to create a shared library (that example below). This works: $ gcc -static -fpic scale.c -o libscale.so -shared -m32 This fails: $ gcc -static -fpic scale.c -o libscale.so -shared -m64 /usr/bin/ld: /opt/spdtools/compiler/ia32e/gcc-4.1.0/lib/gcc/x86_64-unknown- linux-gnu/4.1.0/crtbeginT.o: relocation R_X86_64_32 can not be used when making a shared object; recompile with -fPIC /opt/spdtools/compiler/ia32e/gcc-4.1.0/lib/gcc/x86_64-unknown-linux- gnu/4.1.0/crtbeginT.o: could not read symbols: Bad value collect2: ld returned 1 exit status Version-Release number of selected component (if applicable): $ gcc -v Using built-in specs. Target: x86_64-unknown-linux-gnu Configured with: ../gcc-4.1.0/configure -- prefix=/opt/spdtools/compiler/ia32e/gcc-4.1.0 Thread model: posix gcc version 4.1.0 How reproducible: I was able to reproduce this problem with gcc 3.2.3 and 4.0.0 on x86_64. I did not see the problem using gcc 4.1.0. Steps to Reproduce: 1. Copy test case (below) to an x86_64 machine 2. Compile the test case: gcc -static -fpic scale.c -o libscale.so -shared -m64 3. Look for error message Actual results: // Fails with -m64 % gcc40 -static -fpic scale.c -o libscale.so -shared -m64 /usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/4.1.0/crtbeginT.o: relocation R_X86_64_32 against `__deregister_frame_info' can not be used when making a shared object; recompile with -fPIC /usr/lib/gcc/x86_64-redhat-linux/4.1.0/crtbeginT.o: could not read symbols: Bad value collect2: ld returned 1 exit status Expected results: // Works with -m32 % gcc40 -static -fpic scale.c -o libscale.so -shared -m32 % Additional info: Here's the test case: % cat scale.c #include <stdio.h> int scale(int val) { const int scalefactor = 999; int i= scalefactor * val; printf("scalefactor=%i. val=%i. i=%i \n", scalefactor, val, i); return i; }
