Well, then I'll skip the .def file anyway.

gcc/ld problem
Hallo Cygwinners, I'm trying to link a library with gcc -shared plus some ld options: gcc -shared -o Zlib.dll -Wl,--out-implib=libZlib.dll.a -Wl,--output-def libZlib.def -Wl,--export-all-symbols -Wl,--enable-auto-import \ -L/usr/local/lib Zlib.o /usr/local/lib/perl5/5.7.2/cygwin-multi-64int/CORE/libperl.dll.a -L/usr/local/lib -lz gcc: libZlib.def: No such file or directory Now I'm getting this error. I thought -Wl,--output-def name.def is the option to tell ld that it should create this .def file, now I'm confused, why does it tell me No such file or directory? >From the ld --help output: ... --out-implib Generate import library --output-def Generate a .DEF file for the built DLL ... And the .info says: `--output-def FILE' The linker will create the file FILE which will contain a DEF file corresponding to the DLL the linker is generating. This DEF file (which should be called `*.def') may be used to create an import library with `dlltool' or may be used as a reference to automatically or implicitly exported symbols. It works well if I skip this flag. It works well if I do a: $ touch libZlib.def before running gcc -shared. Is this the expected way? Do I have to create an empty .def file before linking? Or is something with my setup broken? Do I need .def files?
