Symbol conflict between libc and libpthread

Hi,

I am trying to build a small program that needs both libc and libpthread as follows -

UCLINUXBASE=/usr/local/uClinux
ARMTOOLS=/usr/local/arm-uclinux-tools
CROSS_COMPILE=arm-uclinux
CR_CC=$ARMTOOLS/bin/$CROSS_COMPILE-gcc
CR_LD=$ARMTOOLS/bin/$CROSS_COMPILE-ld
CR_OBJCOPY=$ARMTOOLS/bin/$CROSS_COMPILE-objcopy

$CR_LD -r -T ${ARMTOOLS}/lib/elf2flt.ld \
${UCLINUXBASE}/arm-uclinux/lib/crt0pic.o \
thread.o \
-L${ARMTOOLS}/lib/gcc-lib/arm-uclinux/2.96/soft \
-L${UCLINUXBASE}/arm-uclinux/lib -lpthread -lc -lgcc -m armelf_uclinux \
-o thread.elf

Linker throws the following errors

/usr/local/uClinux//arm-uclinux/lib/libc.a(errno.o): In function '__errno_location': errno.o(.text+0x0): multiple definition of '__errno_location'

/usr/local/uClinux//arm-uclinux/lib/libpthread.a(errno.o)(.text+0x0): firstd efined here

/usr/local/uClinux//arm-uclinux/bin/arm-uclinux-ld: Warning: size of symbol '__errno_location' changed from 100 to 28 in errno.o
Can't open thread.elf

Any clues on why there is a symbol clash between libc and libpthread?

Thanks,

could you please specify the version and release of the kernel you are using for your compilation....i really doubt if this is the problem but worth a look....

just as an addon: why are you explicitly linking with libc...i think the compiler(the linker part of it) should be doing it anyway...

have you tried removing the -lc and then compiling it?

is it solved? or still u r having the same problem.
