Error compiling on windows: can't open SDL2main.lib #1

Open Geof23 opened 4 years ago

I followed the instructions for building on Windows in README. What am I missing?

clang++ *.cpp -I.\include\ -Llib -L. -lglew32s -lSDL2main -lSDL2 -o fractals.exe -lopengl32

Hi @Geof23 !

Can you please remove the -L. part from your command? I believe that by running the command you specified above which has two instances of the -L argument option, you are overwriting -Llib, which is the argument option that specifies the path to the libraries that are to be linked (thus the compiler is searching for the libraries in ., the root directory of the repository, and not on the /lib directory where it should be looking).

Please try removing the duplicate -L. option and tell me if that works.

You can have multiple -L args. It’s finding the other libs in lib

Anyway, Ruben, I appreciate you getting back so quickly.

When I use your suggestion, I get the same problem:

clang++ *.cpp -I.\include\ -Llib -lglew32s -lSDL2main -lSDL2 -lOpenGL32 -o fractals.exe

@Geof23 No problem! I would kindly ask you to try out the gcc g++ compiler instead, for the time being. I had a buddy of mine do a clean installation of this repository using the MINGW compiler and it worked for him on a Windows machine.

Geof23 commented 4 years ago

Cool, Ruben -- I'll let you know what works
