Running Makefile with nmake -f on Windows: fatal error U1033: syntax error : '=' unexpected #12

Closed vexe closed 8 years ago

vexe commented 8 years ago

Also, adding the header files to my project and #including them yield all sorts of linker errors (e.g. the sample code you have in the readme), which is why I tried the Makefile. I thought I could just drop in the header files and include them and things would go cozy, not the case it seems.

Am I missing something?

To use Font-Stash, copy fontstash.* and stb_truetype.* to your project and include fontstash.h.

The Makefile was written for GNU make on Linux. I guess it needs some changes to work with nmake and you would need sdl-config and pkg-config on Windows. So you probably shouldn't use the Makefile on Windows.

If you want to compile the sample program (main.c) on Windows, you need to install SDL and SDL_image. Then you have to figure out, how to compile a program using these libraries and OpenGL. That depends heavily on your development environment (compiler, editor/IDE). The Makefile can give you some hints, though.

What linker errors do you get?

Thanks for the reply. Yes I included all the headers including Sean's files (4 files in total) I just copy-pasted the sample code you had in the repository under the usage section (not in main.c) and got:

This looks like you are compiling your code as C++. Could you try wrapping fontstash.h in extern "C" { } like in the following commit: lsmoura/Font-Stash@ab33e3c5e93943b86e3295f5a09c290a674ce4f4

That worked, thanks!
