Folks,
I am having trouble linking with a normal Windows import library file when creating a DLL on Cygwin. These same import libraries worked fine when creating static Cygwin executables with older versions of Cygwin.
The error is: "error adding symbols: File in wrong format".
This is an example of the error (I have reformatted the long g++ command onto multiple lines to make it more legible):
$ make
make -C O.cygwin-x86 -f ../Makefile TOP=../../.. \
T_A=cygwin-x86 install
make[1]: Entering directory '/cygdrive/j/epics/devel/dxp/dxpApp/handelSrc/O.cygwin-x86'

So it is complaining that the library PlxApi.lib is not in the correct format. However, this is definitely a valid Windows import library file.
Thanks,

Additional information:
- This is Cygwin 2.0.1, 32-bit on a Windows 7 64-bit machine.
The "file" utility claims it is an archive file:
$ file ../../lib/cygwin-x86/PlxApi.lib
../../lib/cygwin-x86/PlxApi.lib: current ar archive
The "nm" utility appears to interpret the file OK:

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 ?
