Build json-c-0.10 on Win32 system

[Borman Squirrel]

Hi,

I am trying to build json-c-0.10 on win32 ... I've tried to do that under mingw-msys, renaming  config.h.win32 to config.h following the instructions provided in the readme but gives me this error:

Has Anybody been fought with that? :)

On Linux these things like int32_t are defined in a types.h file, which you probably have but may need to include the path to the directory containing the types.h file.

One of my co-workers who is a Windows guy (I'm pretty much linux only) said that json-c is included in the Cygwin library list, so you may want to take the Cygwin route.

Good luck!

This should be handled by the json_inttypes.h header, but it's written with the assumption that if you're building on windows then you're using visual studio.  I doubt anyone has tried building with mingw, so you likely have some work to do to get this working.  Patches are, of course, appreciated.

Do you have a inttypes.h present on your system?  If so, did json_config.h get populated with JSON_C_HAVE_INTTYPES_H set to 1?  If not, you can probably fix a lot of those errors (temporarily) by editing that file.

Thanks for the response!

Yes I know, on Cygwin works good, but I was trying to avoid cyg***.dll dependencies ... I have seen that there was a branch to build the library with Cmake but I don't know if it's considered on 0.10 version.
