*.dll.a is an import library
|
||||
|
||||
libtool makes an import library when you link against a DLL
|
||||
|
||||
dlltool --as=as --dllname cygmodule2-0.dll --def .libs/cygmodule2-0.dll-def --output-lib .libs/libimp-cygmodule2-0.a
|
||||
|
||||
the dll-def file is created at the time that the DLL is created.

LIB would have produced the file DLL1.EXP as well. You must use DLL1.EXP as

this makes a symbol table for a file

These lines from test4 show that libtool does know how to make

import libraries:

a BINARY.

Libraries have been installed in:

|

|

If you ever happen to want to link against installed libraries
|
||||
in a given directory, LIBDIR, you must either use libtool, and
|
||||
specify the full pathname of the library, or use the `-LLIBDIR'
|
||||
flag during linking and do at least one of the following:
|
||||
- add LIBDIR to the `PATH' environment variable
|
||||
during execution
|
||||
- add LIBDIR to the `LD_RUN_PATH' environment variable
|
||||
during linking
|
||||
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
|
||||
