Thanks for your answer and it works. I have one more question:
I read the following from the how-cygtls-works.txt "If you load cygwin1.dll dynamically from a non-cygwin application, it is vital that the bottom CYGTLS_PADSIZE bytes of the stack are not in use before you call cygwin_dll_init()" How do I make sure bottom CYGTLS_PADSIZE bytes of the stack are not in use before you call cygwin_dll_init()" I could not find any information at: winsup/testsuite/cygload On 5/2/07, Brian Dessent <[EMAIL PROTECTED]> wrote:

This happens automatically for executables compiled with gcc, but otherwise you need to explicly init the library. The details are all in the FAQ. > gcc -shared -I ../../cygwin/usr/include/cygwin -o testdll.dll test.cpp > -Wl,--output-def,testdll.def,--out-implib,libtestdll.a > > Command used to create the library file: > > "C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\lib" > /machine:i386 /DEF:testdll.def Why not simply "cp libtest.dll.a testdll.lib"? They're the same thing.
