Thanks a lot for opensourcing indic text renderer code.

I tried using indic-text-renderer in my windows machine using cygwin. Followed steps in http://indic-text-renderer.googlecode.com/git/HowToBuild.txt document.

I got upto ./autogen.sh step successfully. After that while running make command I encountered the following issues. Please help to resolve this.

Hi Mugunth, Thank you for trying this out. I haven't seen this error before: error: `__sync_fetch_and_add' undeclared

Looks like a missing library, or could be because of some version incompatibility also. Are you having latest version of Cygwin (including gcc, make etc) on your machine?

Also, given that it is an error while building Harfbuzz-ng itself, we could report this error on Harfbuzz-ng mailing list as well and see if there is some help we can get there.

This is due to build environment does have all the build tools/libs. Kindly check out the same.

My bad. Pushed a fix to HarfBuzz master.

Thank you Behdad for fixing this and letting us know.

Thanks Behdad, I pulled fresh version of the code from git and tried autogen.sh & make (after make clean ).

Now the make goes past that error. But hit with another error. hb-ot-map-private.hh:110: error: `typedef struct hb_ot_map_t::pause_callback_t hb_ot_map_t::pause_callback_t' is private hb-ot-map-private.hh:183: error: within this context

If you could help in this it would be great.

Here is the full error detail:
