Hi,
I am trying to build cdo (https://code.zmaw.de/projects/cdo) from source and have a common problem:
*** Warning: This system can not link to static lib archive /usr/local/lib/libsz.la.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have.
I looked at my build of libsz (from hdf's szip http://www.hdfgroup.org/HDF5/release/obtain5.html#extlibs ) and even though I specified --enable-shared it did not build the shared libraries. Why is this?
I looked at libsz.la and manually built a dll from the object files:
gcc -shared -o libsz.dll rice.o sz_api.o encoding.o
but copying the resulting libsz.dll to /use/local/lib is not enough for the cdo build to recognize it as the shared library. It still tries to link to libsz.la
Do I need *.dll.a for libsz? How do I do this and where do I put the final libsz.dll and corresponding libsz.dll.a?
Pointing me to any documentation would be appreciated. All I have found is Building and Using DLL's in the Cygwin users manual.
Thanks,
Brendan
