MSVC tool doesn't work

[Makogan]

I compiled the incbin.c file and made an executable if I run it with help I get:

 ./a.exe phong_lighting.glsl  -I../../Src/Engine/EmbeddedShaders/ -o ../../buildvs/data.c  -help
C:\Users\Makogan\Documents\neverengine\libraries\incbin\a.exe [-help] [-Ipath...] | <sourcefiles> | [-o output] | [-p prefix]
   -o         - output file [default is "data.c"]
   -p         - specify a prefix for symbol names (default is "g")
   -S<style>  - specify a style for symbol generation (default is "camelcase")
   -I<path>   - specify an include path for the tool to use
   -help      - this
example:
   C:\Users\Makogan\Documents\neverengine\libraries\incbin\a.exe source.c other_source.cpp -o file.c
styles (for -S):
   camelcase
   snakecase

If I try to run it normally (without the help flag) this is the data.c file that gets generated:

/* File automatically generated by incbin */
#include "incbin.h"

#ifdef __cplusplus
extern "C" {
#endif


#ifdef __cplusplus
}
#endif

No errors or warnings are thrown by the tool.

I am on windows 10

You need to list the source files which use INCBIN you want preprocessed by this tool, you don't list the data files, those are read from the INCBIN macro in the source file which are found via -I. So for instance you'd have:

// source.c
INCBIN(data, "phong_lighting.glsl");

Then you'd run the tool with ./incbin.exe source.c -I../../Src/Engine/EmbeddedShaders/ -o ../../buildvs/data.c
Which would emit a data.c file containing the phong shader source code as a byte array named data, now in source.c you can use data to refer to that embedded GLSL.

If you have multiple source files which use INCBIN you'd specify them all on the command line here.

Ah I see, I was confused, thank you!

I was confused too. I think the description of how to use it should be clearer. I didn't understand that source.c was suppossed to be the source file that contains the INCBIN macros.

Maybe you should add a little counter so it's easier to understand that nothing was found?
