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,
Mark Rivers
