How to link this on Cmake?

[Dekadencee]

I tried to use spot on one of my proyects for convert .dds files to .jpg but I always get external simbols error on spot::color.

Any tip o idea to integrate this?

Are you linking against spot.cpp and spotc.c files? You need spot.hpp, spot.cpp and spotc.c files only. They're in the root project folder. Any other file is unneeded.

I link spot as library, sorry my bad, now I link spot as simple files of my proyect:

FILE(GLOB SpotFiles
    deps/spot/spot.hpp
    deps/spot/spot.c
    deps/spot/spot.cpp
)

add_executable(
    MyProyect
    ${SpotFiles}
    ${MainFiles}
)

And on my code:

#include "spot.hpp"

spot::image img = spot::image(dds.string().c_str());
img.save_as_jpg(out.c_str(), 100);

But still showing linking errors(LNK2019) on my proyect :( on this functions:

• WebPGetInfo on "bool cdecl spot::info(struct spot::stream &,void const *,unsigned int64)"
• WebPDecodeRGBA on "bool __cdecl spot::decode(struct spot::stream &,struct spot::stream const &)"
• WebPEncodeRGBA on "class std::basic_string<char,struct std::char_traits,class std::allocator > __cdecl spot::internals::encode_wbp(unsigned int,unsigned int,void const *,unsigned int)"

I don't know what its wrong now :/ my /deps/spot/ its a submodule of master of this repo, im building this on x64.

Don't rename spotc.c as spot.c. Try to keep the original name and tell me if it works :) In your current setup spot.c will get converted into spot.o once compiled, but then spot.cpp as spot.o again (hence, overwriting the previous C file and missing all the whole file you previously compiled)

Yes sorry, the fail its on "deps/spot/spot.c", i don't see that have a aditional "c" on his name, i renamed it to "deps/spot/spotc.c" and now the build it's fine ^^

A lot of thanks, I apreciate a lot your work, so usefull lightweight libraries for any proyect ^^
