-lpthread

when I build a project, I have "-lpthread" in Libraries. But it shown that "cygdrive/e/altera/kits/nios2_51/bin/nios2-gnutools/H-i686-pc-cygwin/bin/../lib/gcc/nios2-elf/3.4.1/../../../../nios2-elf/bin/ld: cannot find

-lpthread". Can anyone know why? thanks!

    Hi,hippo

    I have resolved this problem by adding uClibc/lib. But when I upload to the flash

    and run under uClinux. Another comes out, "BINFMT_FLAT: bad magic /rev(0x10101ff,need 0x4)", can you tell me why? thanks!

    Silly question here... Did you compile your executable with the "-elf2flt" option? The kernel is expecting to see a FLT (not ELF) formatted executable.
