Raylib: First Program won't build - CLITERAL expected expression

[SethArchambault]

Okay I'm starting out with building my first program, coming from a handmade hero background, and I'm looking to make games in Raylib without using Xcode, just using Vim, and building from commandline. Unfortunately, I seem to be messing up some of the linking..

I've installed glfw with brew, and it's located: /usr/local/lib/libglfw.3.2.dylib

The other dependencies are in the same folder as test.cpp, I'm really not sure what's happening here..
Any clue? thanks!

Error:
````
test.cpp:11:20: error: expected expression
ClearBackground(RAYWHITE);

Seems related to C++ file compilation with clang++... CLITERAL definition don't seem to be defined correctly.

Have you tried compiling test.c and using clang?

You can also try commenting that line about CLITERAL if using clang++.

[SethArchambault]

@raysan5 Appreciate the quick response!

Okay I've commented the CLITERAL lines using clang++ so that this line is active:

````

define CLITERAL (Color)

````

That almost worked, but now it looks like the system is looking for OPENGL functions, which according to the instructions for Mac OSX is not mentioned anywhere:

https://github.com/raysan5/raylib/wiki/Compile-for-OSX

(See Error at the bottom)

I see the same issue if I run clang as you recommended.

#clang++ -g -I/w/raylib_build/raylib/release/osx -L/usr/local/lib -L/w/raylib_build/raylib/release/osx -lglfw.3.2 -lraylib test.cpp -o test clang -v -I/usr/local/lib -lglfw -L/w/raylib_build/raylib/release/osx -lraylib -I/w/raylib_build/raylib/release/osx test.c -o test

I'm a little worried about these strange issues so early on, but I'm willing to work through them if this can help people further down the line.. Thanks!

@raysan5 Yes! I figured it out!

Found a guide here:
http://forum.raylib.com/index.php?p=/discussion/110/setup-guide-for-osx-w-atom

Looks like your forum is a good resource, that's a good sign :)

Here's my final build script:

For C++

clang++ -I/w/raylib_build/raylib/release/osx -L/usr/local/lib -L/w/raylib_build/raylib/release/osx -lglfw -lraylib -framework GLUT -framework OpenGL -framework Cocoa test.cpp -o test

For C

clang -I/w/raylib_build/raylib/release/osx -L/usr/local/lib -L/w/raylib_build/raylib/release/osx -lglfw -lraylib -framework GLUT -framework OpenGL -framework Cocoa test.c -o test

I'm sure if this was added to the documentation for OSX, it would save someone else the trouble of getting stuck and possibly giving up early..

[SethArchambault]

I've added the documentation to the wiki, things are going well now!

[raysan5]

Hey @SethArchambault! Excuse me for the late response! I see you finally managed to ga through this issue! Great! :D

By the way, are you using latest develop branch? It contains raylib 1.8, I'm about to publish it...

Thank you very much for trying raylib and adding the info to the Wiki!

[SethArchambault]

No I'm using master, would you recommend I switch to develop?

Liking the library so far! I'm coming from SDL - I never dared look at the underlying code there, but this code is very readable, so I'm able to adapt very quickly, so far so good!

[raysan5]

I recommend using develop branch, it always implements latest changes and improvements. I also try to keep the branch stable. But right now most of the changes have been already merged into master because I'm preparing to publish next release...

raylib is similar to SDL in some things but as I developed it for education, I focused on source readibility and simplicity... one of the objectives was not only making it easy-to-use but also easy to understand internals.
