  • Dear Steve,

    You need to add the math library (libm) that contains pow.

    Add -lm to the end of the compile line or to LIB

    Hi,

    executables, sac-101.4-linux-x86_64.

    my makefile contains
    LIB = -L/usr/local/sac/lib -lsacio
    sac2rsam: sac2rsam.o
    gcc -c sac2rsam.c -o sac2rsam.o $(LIB)
    gcc -o sac2rsam sac2rsam.o $(LIB)

    This gives an error:
    make sac2rsam
    gcc -c sac2rsam.c -o sac2rsam.o -L/usr/local/sac/lib -lsacio
    gcc -o sac2rsam sac2rsam.o -L/usr/local/sac/lib -lsacio
    /usr/local/sac/lib/libsacio.a(math.o): In function `powi':
    math.c:(.text+0xf1): undefined reference to `pow'
    collect2: ld returned 1 exit status
    make: *** [sac2rsam] Error 1

    If I assume sacio is 32-bit and add -m32 after gcc in my makefile I
    get a different error:
    make sac2rsam
    gcc -m32 -c sac2rsam.c -o sac2rsam.o -L/usr/local/sac/lib -lsacio
    In file included from /usr/include/features.h:385,
    from /usr/include/stdio.h:28,
    from sac2rsam.c:5:
    /usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file
    or directory
    make: *** [sac2rsam] Error 1

    Does anyone know how I should proceed?

    Many thanks

  • Hi

    Does you have the necessary files to compile 32bits code installed in your
    fedora ? Normally you would need some 32 bits header files. Something like
    libc32-dev, or libgcc32-dev or something like this ....

    regards,

    Marcelo
