Hi! I have been using libtool for one of my projects under linux and now I am in the progress of porting this project to windows using Cygwin.
Fortunately, all the configuration stuff worked fine, but when it came to the compilation part, some things went wrong. I have native Windows DLLs and the approriate .def files which I converted to import libraries using dlltool. dlltool --def /cygdrive/c/MATLAB6p5/extern/include/libmat.def --dllname libmat.dll --output-lib libmat.a The same for the other libraries. Three C++ files are compiled and then linked together to create a shared library but that shared library depends on the former mentioned Windows DLLs. Every time libtool wants to link all compiled files together it gives the following warning: *** Warning: linker path does not have real file for library -lmex. *** 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 *** because I did check the linker path looking for a file starting *** with libmex and none of the candidates passed a file format test *** using a file magic. Last file checked: /cygdrive/c/matlab6p5/bin/win32/libme x.dll The same warning comes for -lmat and -lmx (the shared library should link against the Matlab MEX interface). After that libtool only creates a static version of the library. This would normally be okay but I cannot link to my library. I have some C++ files that use my library but when they should be created the compiler/linker only produces 'undefined reference to ...' errors. The strange thing is that I can compile everything manually and link everything together without using libtool. This works fine. So, to sum up: * I have three files which should become one shared library referencing three other libraries for which I have created the import libs. * I have some C++ source files which reference the created library and themselves should be come shared libraries. I have searched on the Internet for information about this or similar problems but found nothing useful.
