  • 1.  gcc: invalid magic number

    Posted 09/25/25 12:18 PM
    Edited by Emanuel Reisinger 09/25/25 12:18 PM

    Hi,

    it seems it's a similar problem to  gcc: strange error message at config stage but I cannot solve it with setting LIBPATH.

    I've try to compile ghostpdl-10.06.0 but I get the error The module has an invalid magic number. So gcc will try to load a 64Bit library instead of the 32Bit one I guess.

    Our source problem is that we have to convert a pcl file into a tiff with Image Magick v7

    # magick -version

    ... and the installed pcl6 (from ghostpdl-9.06) does not support the used png16malpha device from magick.

    So I've try to compile the new version of ghostpdl and hope it supports this device. But with no luck with compiling.

    With unset LIBPATH it does not work either. (./configure && ./make)

    What's wrong?

    I whish I could installghostpdl from aixtoolbox ;-)

    Try to build a 64bit version of ghostpdl. ( Pass -maix64 to gcc during the compilation and OBJECT_MODE=64 ).

    Can you help me how I can set the correct parameters or arguments to build a 64bit version?

    ghostpdl is a huge package configured by configure and all Makfiles for all submodules are generated. I've tried with export some variables

    export OBJECT_MODE=64
    export CFLAGS="-maix64"
    export CXXFLAGS="-maix64"
    export LDFLAGS="-maix64"
    export AR="ar -X64"

    ... call configure with arguments

    ./configure CFLAGS="-maix64" CXXFLAGS="-maix64" LDFLAGS="-maix64" AR="ar -X64"

    Only the initial error from initial post with genarch is gone and after a while compiling I get the next 32/64Bit error.

    ...

    As I can see in the gcc call above the CFLAGS are not considered.

    I haven't found out what I have to do.

    Have anyone any idea?

    My fault, I can see the -maix64 flags in gcc command.

    I've tried the whole build with -m64 but with the same result/error.

    Can you try the below ? 
    gmake distclean
    export CC="gcc -maix64 -pthread -O2" 
    export OBJECT_MODE=64
    ./configure

    I get still the same error.

    ld: 0711-738 ERROR: Input file ./obj/tessocr.o:
            XCOFF32 object files are not allowed in 64-bit mode.

    There is something strange happening. Because the object is built with -maix64 before. But at time of linking it's a 32Bit object.

    g++ -Itesseract/include -Itesseract/src/api -Itesseract/src/arch -Itesseract/src/ccmain -Itesseract/src/ccstruct -Itesseract/src/ccutil -Itesseract/src/classify -Itesseract/src/cutil -Itesseract/src/dict -Itesseract/src/lstm -Itesseract/src/opencl -Itesseract/src/textord -Itesseract/src/training -Itesseract/src/viewer -Itesseract/src/wordrec -Ileptonica/src -I./base -I./obj -maix64 -pthread  -std=c++17  -DHAVE_MKSTEMP -DHAVE_FILE64 -DHAVE_FSEEKO -DHAVE_MKSTEMP64 -DHAVE_FONTCONFIG  -DHAVE_SETLOCALE   -DHAVE_BSWAP32  -DHAVE_STRERROR -DHAVE_ISNAN -DHAVE_ISINF  -DHAVE_PREAD_PWRITE=1 -DGS_RECURSIVE_MUTEXATTR=PTHREAD_MUTEX_RECURSIVE -O2 -DNDEBUG -Wl,-brtl -D_LARGE_FILES -Wall  -Wundef -Wmissing-declarations  -Wwrite-strings -fno-strict-aliasing  -fno-builtin -fno-common -Werror=return-type -Wno-unused-local-typedefs -DHAVE_STDINT_H=1 -DHAVE_DIRENT_H=1 -DHAVE_NDIR_H=0 -DHAVE_SYS_DIR_H=1 -DHAVE_SYS_NDIR_H=0 -DHAVE_SYS_TIME_H=1 -DHAVE_SYS_TIMES_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_LIBDL=1 -DGX_COLOR_INDEX_TYPE="unsigned long long" -D__USE_UNIX98=1 -DHAVE_SNPRINTF -DGS_MEMPTR_ALIGNMENT=8 -DBUILD_PDF=1 -I./pdf -maix64 -DHAVE_RESTRICT=1 -DHAVE_LIMITS_H=1 -DHAVE_STRING_H=1 -DUSE_LIBICONV_GNU -DPNG_POWERPC_VSX_OPT=0 -fno-strict-aliasing -DHAVE_POPEN_PROTO=1    -DTESSERACT_IMAGEDATA_AS_PIX -DTESSERACT_DISABLE_DEBUG_FONTS -DGRAPHICS_DISABLED -UCLUSTER -DOCR_SHARED=0 -DLEPTONICA_INTERCEPT_ALLOC=1 -I./obj/ -o ./obj/tessocr.o -c -DTESSDATA="/usr/local/share/tessdata" ./base/tessocr.cpp

    When I remove the ./obj/tessocr.o and built it with this command it's a 64bit object.

    In my console output tessocr.o is used in this line once more

    ./obj/aux/echogs -e .dev -w- -l-obj ./obj/libocr_1_0 ./obj/tessocr.o

    It's completely strange.

    After I have build tessocr.o again, now it's really 64Bit, make results in more linkage errors:

    Oh.. It involves g++ also., 
    We need to set CXX also then to "g++ -maix64 -pthread -O2" . Clean it up and start afresh., 

    gmake distclean
    export CC="gcc -maix64 -pthread -O2" 
    export CXX="g++ -maix64 -pthread -O2" 
    export OBJECT_MODE=64

    Better.

    I am not sure how "-L/opt/freeware/lib64 -L/opt/freeware/lib" flags are added to it. If you can pass "-L/opt/freeware/lib/pthread" before this , that will resolve this problem.

    That worked.

    Conclusio:

    # gmake distclean

    export CC="gcc -maix64 -pthread -O2"

    export CXX="g++ -maix64 -pthread -O2"

    export OBJECT_MODE=64

    ./configure

    Add -L/opt/freeware/lib/pthread before the other library paths in line EXTRALIBS in Makefile:

    EXTRALIBS=$(XTRALIBS) -lm -ldl  -liconv -L/opt/freeware/lib/pthread -L/opt/freeware/lib64 -L/opt/freeware/lib -lfontconfig -lfreetype

    make -j32

    Thank you for your help Ayappan!
