apparently I also need libgw32c which define correct header and structure required by libarchive while developing
I could download them both from there:
http://gnuwin32.sourceforge.net/packages/
==>
http://gnuwin32.sourceforge.net/packages/libarchive.htm
http://gnuwin32.sourceforge.net/packages/libgw32c.htm
I was not able to install correctly libgw32c, I mean whatever I do I had plenty of error message during the compilation (with some error in the system header introduced by libgw32c).
-- error like that ---
c:/GNUstep/Development/msys/1.0/mingw/include/winx/stdiox.h: In function `__flbf':
c:/GNUstep/Development/msys/1.0/mingw/include/winx/stdiox.h:64: structure has no member named `_flag'
c:/GNUstep/Development/msys/1.0/mingw/include/winx/stdiox.h: In function `__fpending':
c:/GNUstep/Development/msys/1.0/mingw/include/winx/stdiox.h:69: structure has no member named `_ptr'
.... continued ....
--------------------
If I try without libgw32c my program compile but fail. for some reason one archive_write_data fail with either:
Numeric group ID too large: Result too large
or
GZip compression failed
depending wether or not I use GZip compression or not.
As I'm thining the problem *might* comes from 'struct stat' I try define a custome one which fit the form I would expect.
but still got the same errors...
I'm quite at loss, could anyone provide some guidance? or link? or whatever?
