Problem with Windows build - freetype.dll: %1 is not a valid Win32 application

[Mads Bondo Dydensborg]

Hi there

As written about earlier, I have compiled OpenJDK on Windows 7 64 bit, using Visual Studio 2010 Express SP 1, under Cygwin. (eventually: make clean images). AFAIK, VS Express will only build a 32 bit image, and has done. A simple HelloWorld test seems to work. However, if I try to run anything graphical, I get a linker error regarding Freetype:

....(lots of FontManager => ClassLoader$NativeLibrary stuff).

I am a bit new to Windows, but checking the lib in question:

$ file freetype.dll

$ ldd freetype.dll
        ntdll.dll => /cygdrive/c/windows/SysWOW64/ntdll.dll (0x77e70000)
        kernel32.dll => /cygdrive/c/windows/syswow64/kernel32.dll (0x75900000)
        KERNELBASE.dll => /cygdrive/c/windows/syswow64/KERNELBASE.dll (0x75a10000)

I am not sure if it is 32 or 64 bit, really...

As part of the build process, I had to create a copy of freetype.dll.a - this was installed in the X86 part of the Windows Program Files directory - I assumed that it was 32 bit.

Any help/hints much appreciated.

Thanks,
