MingW compile driving me nuts

[michealvleugel]

Trying to compile Imagemagick on Windows using MingW/MSYS but I am going nuts in the process. I want to distribute my own app (which uses the C wand api) as a single installer, so that requires Imagemagick + delegates to be independent of absolute filepaths/registry etc (all dll's in one dir would be fine). I managed to compile everything ok without the delegates, using --without-modules, and also had no problems compiling it with only ./configure (the coders then end up somewhere in my ming directory) But now...the delegates, without a hardcoded path...

Jpg is no problem as well as some others but as soon as I try to compile anythin that depends on Zlib (freetype, png, tiff) I get this error:

Can anyone please help me? ANy help is greatly appreciated.

Cheers,

Oh yeah - almost forgot - using IM 6.4.1 and all source files in the "delegates" folder on the FTP server.

It looks like your build is needs the Zlib library, generally -lz.

The default Visual C++ build is "non-installed" which means no Window registry is required. Create a static build to reduce the number of dependencies.

Hmmm - have the gzlib installed, tried the gnuwin32 install and to compile it myself - no luck. Arn't "multiple definition" errors in gcc generated when objects are linked twice?

Thanks for our help!

Ok found what looks like a solution - it now builds ok with tiff, png and zlib.

There is an offending passage in the configure file of libpng (1.2.29):

#ifdef __cplusplus
extern "C"
#endif
char zlibVersion ();
int
main ()
{
return zlibVersion ();
;
return 0;
}
_ACEOF


After changing return 0; into return "1.2.3"; it worked.

Only took me 3 full days to get IM to compile with mingW - about the same amount of time it took me to write my application in the first place
