digitalmars.D.learn - DLLs with Cygwin don't work
The following: 1. created test C-dll in Cygwin (gcc -shared -o hello.dll hello.o) 2. used "implib.exe /s" to create .lib file 3. linked with D program "dmd test.d hello.lib" Compiles, program starts but begins to hang as soon as it calls the C function (which itself is never executed, no "hello world" is printed). Windows 7, 32bit. In the past it worked flawlessly. Windows 7 had a few updates recently and I updated Cygwin (and of course dmd). I noticed this behavior in a customized C-library and wanted to rule out it's the library (which works perfectly well on Linux). So I wrote a simple "hello world" dll, to see what happens. Exact same behavior. Any ideas? Thanks!
