I got the same problem as Mark Rivers, already reported with the
same subject.
I'm running cygwin 32-bits version 2.0.3 under Windows 7 64 bits
I got from a hardware manufacturer a DLL N957lib.dll and the
associated import library N957lib.lib
When I try to link a small test program with the command:
gcc -Wall -DWIN32 -I. -o tst tst.c ./N957lib.lib
I get the message:
"N957lib.lib: error adding symbols: Format de fichier non reconnu" (File
in wrong format)
Now if I use the MingW compiler (either under cygwin or Msys):
i686-pc-mingw32-gcc -Wall -DWIN32 -I. -o tst tst.c ./N957lib.lib
everything is fine and the program (tst.exe) executes as expected,
for example printing error messages issued by the library.
But this doesn't help me because I need the full cygwin capabilities
(X11, Lesstif)
The cygwin gcc version is 4.9.2, while the MingW one is 4.7.3, so that
it seems
that there is a problem in decoding .lib libraries with the newest gcc
versions.
I tried to bypass the problem by re-building the .lib from the dll by
using pexports
and dlltool. I get a .lib with the right format, readable by gcc, but
some references are still missing
at the link stage.
Any hint about the gcc (ld) decoding of .lib ?
