[Java-readline-devel] Re: Building Java readline on Cygwin

[Bernhard B. <ma...@ba...>]

Hi,

the very last lines of org_gnu_readline_Readline.c read:

#ifdef WIN32
int WINAPI
readline_init(HANDLE h, DWORD reason, void *foo) {
  return 1;
}
#endif

These define a necessary function for DLLs. This might be the reason why 
loading of the DLL failes (the log does not show if you defined WIN32). But 
don't set it to CYGWIN or cygwin, or else the makefiles work different (it 
seems that cygwin does not need all the stuff anymore in 
src/native/Makefile).

Maybe you could describe your cygwin-environment, because I never got that far 
and I wan't to reproduce it if possible.
