Hi, Larry:

I have two c-callable static libs which are created by vc, but the source 
codes are not available.
I need these libs to create a shared library using gcc under cygwin.

Command line:

gcc -shared -o libmpi.dl 
mpi_chdl.o ../../src/lib/libmpi.a ../../src/lib/liblam.a ../../src/lib/chsd
k.lib ../../src/lib/ch.lib

Error message:

Warning: .drectve '/DEFAULTLIB:"MSVCRT" /DEFAULTLIB:"OLDNAMES" /EXPORT:___b
uiltin_Ch_VaArg ' unrecognized
Cannot export .idata$4: symbol not found
Cannot export .idata$5: symbol not found
Cannot export .idata$6: symbol not found
Cannot export .text: symbol not found
Cannot export ⌂ch_NULL_THUNK_DATA: symbol not found
collect2: ld returned 1 exit status
make: *** [libmpi.dl] Error 1

Have any idea to fix this problem?

Thanks
