I have a problem when linking a 64 bit application with
libpthread. I appears to link fine, but it will seg fault when I execute
it. I wrote an empty C program called empty.c: int main (void) { return 0; } I cross compile it with: /opt/redhat/mips64linux-031001/H-i686-pc-linux-gnulibc2.2/bin/mips64-linux-gnu-gcc
–mabi=64 empty.c –o empty –lpthread The executable will seg fault. If I remove the
–lpthread, it is fine. Also, if I change the 64 to 32, it is fine. Maybe I have a bad libpthread in /lib64? If I type “file
/lib64/libpthread-0.10.so” I get: “ELF 64-bit MSB shared object,
mips-3 MIPS R3000_BE, version 1, not stripped”. Looks fine to
me. Should I cross compile and replace libpthread? If so, where can
I find the source? The other strange thing is that ldd does not work on 64 bit
applications. It will always return: “not a dynamic
executable”. Does anyone know how this could be fixed? I’m using a PMC Yosemite board with an RM9224
processor. The kernel is 2.6.12 64bit SMP. I am using the PMC
supplied cross compile tools, kernel, and NFS file system. Thanks for your help! |
