    Hi,

    while trying to build curl from source configure bails out with some crazy error...

    configure:34032: checking run-time libs availability
configure:34088: gcc -O2 -o conftest -maix64 -I/opt/freeware/include -Werror-implicit-function-declaration -O2 -Wno-system-headers -maix64 -I/opt/freeware/include -I/opt/freeware/include   -I/opt/freeware/include -L/opt/freeware/lib64 -L/opt/freeware/lib -Wl,-blibpath:/opt/freeware/lib64:/opt/freeware/lib:/usr/lib:/lib -L/opt/freeware/lib   -L/opt/freeware/lib64 conftest.c -lnghttp2 -lssh2  -lssl -lcrypto -lldap -llber -lz  >&5

        The module has an invalid magic number.

configure:34088: $? = 255
configure: program exited with status 255
configure: failed program was:

    i checked some libraries and gcc, but i see no context between the error message and the situation on the compiler side and installed libs.

    Hi,

    Please share the configure script options passed to ./configure and env output .

    gcc being a 32-bit binary has /opt/freeware/lib as it's libpath , so it should not go to /opt/freeware/lib64 to look for libgcc_s.a unless LIBPATH is set. 
    You don't have LIBPATH set which makes this error very surprising. Can you paste the output of "ldd /opt/freeware/bin/gcc" ?

    i did a build with no cflags/ldflags and the least possible configure options and it went through without errors, so it must have something to do with the  flags.
    as i took the flags from your curl spec file one to one  i can not comprehend whats going on here.

    further testing...by setting LIBPATH to contain /opt/freeware/lib BEFORE /opt/freeware/lib64 in the build script ,configure finished successfully. 
    still no idea why gcc insists in loading the 64 bit object before the 32 bit one, smells like a packaging issue in the gcc  package for aix 7.1
