I have a mathematical Library (ADOL-C) that needs to link to an other library (ColPack) for some optional tasks.

I can compile them fine in Linux, and both ADOl-C or ColPack alone in windows, but when I try to compile ADOL-C with ColPack in windows (MinGW 32, ld 2.22) I have the following issue:

$ make
Making all in ADOL-C
make[1]: Entering directory `/c/tests/ADOL-C-2.3.0/ADOL-C'

  CC     int_reverse_t.lo

I can’t just provide the dynamic library as in MinGW, even if I configure ColPack with –enable-shared, I never got actually any shared library from its compilation, only libColPack.[a|la|lai] and ColPack.exe.

Any hint?

    It took a little longer, until I solved the problem.

    Download Colpack-1.0.8.tar.gz and tested it with the following environment

    Msys / mingw 4.7.0.

    As you said, you can not use it to create a shared lib.
    After some time I have found a more complex solution. From this basis I’ve found a shorter way.

    short solution:

    open configure

    line# __________ change ________________ to __

    7660        enable_dlopen=no      set it to yes
7663        enable_win32_dll=no   set it to yes
7673        enable_shared=no      set it to yes
7710        enable_static=yes     set it to no
7717        enable_static=yes     set it to no  
8721        enable_shared_with_static_runtimes=no      set it to yes
11797       enable_shared_with_static_runtimes_CXX=no  set it to yes

    save and run

    ./configure --disable-static --enable-shared

    open libtool

    line# __________ change ________________ to __

    5547        allow_undefined=yes   set it to no
5550        allow_undefined=yes   set it to no

    save and run

    make clean
make

    in the .lib directory should now be following files.

    ColPack.exe      .. 30.08.2012
libColPack.la    .. 30.08.2012
libColPack.lai   .. 30.08.2012
libColPack-0.dll .. 30.08.2012
libColPack.dll.a .. 30.08.2012

    outtake from libColPack-0.dll 

    Export Table:

        ........

    outtake from libColPack.la

    # libColPack.la - a libtool library file
# Generated by libtool (GNU libtool) 2.4 
#
# Please DO NOT delete this file!
# It is necessary for linking the library.

# The name that we can dlopen(3).
dlname='libColPack-0.dll'

# Names of this library.
library_names='libColPack.dll.a'

......

    Hope that helps !

    NOTE:

    Have not tested “make install” !

    To have both static and dynamic:

    Move libColPack.la, libColPack.lai and libColPack.dll.a to another folder. We need them and they will be overwritten. Delete the file libColPack.la, a directory-level higher.

    Change libtool file back to its original state (the 2 lines) .

    Run “make”

    You will have a new libColPack.a

    Move libColPack.dll.a back to .libs

    Merging the content of the two previously moved files with the new libColPack.la (.lai).

    Copy also the updated libColPack.la a directory-level higher.

    The new mixdown file: libColPack.la

    # libColPack.la - a libtool library file
# Generated by libtool (GNU libtool) 2.4 
#
# Please DO NOT delete this file!
# It is necessary for linking the library.

# The name that we can dlopen(3).
dlname='libColPack-0.dll'

# Names of this library.
library_names='libColPack.dll.a'

....

# The name of the static archive.
old_library='libColPack.a'
....

    With this trick you have both static and dynamic libs.
