[Bug java/14074] New: libgcj

[scaccopardo at tiscali dot it]

Hi,

I followed instructions and this time
"make" started classes compilation!!!

But...

$ pwd
/usr/build

$ /usr/src/gcc-3.3.1-3/configure --enable-threads=win32 --enable-sjlj-
exceptions --enable-libgcj --enable-languages=c,c++,java
 --prefix=/usr/local

Now I got this error:

I tried to re-./configure with enable-threads=posix but I got
the same error...So I decided to see source code.

"GC_CreateThread" prototype is under #define(s): (in gc.h)

#if defined(GC_WIN32_THREADS) && !defined(__CYGWIN32__) && !defined(__CYGWIN__)

   GC_API HANDLE WINAPI GC_CreateThread(
      LPSECURITY_ATTRIBUTES lpThreadAttributes,
      DWORD dwStackSize, LPTHREAD_START_ROUTINE lpStartAddress,
      LPVOID lpParameter, DWORD dwCreationFlags, LPDWORD lpThreadId );
[...]

so I think __CYGWIN32__ or __CYGWIN__ are #defined.

Shouldn't I use win32 threads or is there a ./configure option
should I use ?
(Did I have to clean before re./configuring with posix threads and how?
Compilation took really a lot of time and I'd like not to loose compilation 
results...)

Thanks in advance,

Davide

You cannot use win32 threads on cygwin at all, you should be using pthreads.  You will have to redo 
the configure stage and compiling stage, I think this is the documentation somewhere.  Also some one 
has a binary snapshot of gcc (with java) for 3.4 somewhere.
