setup SDL2 mac through command line - c++

Question

I'm trying to setup SDL2 to use with g++, a text editor and terminal.
I have my SDL2.framework in /Library/Frameworks.
I have a folder on my desktop named testsdl which contains two files:
1) main.cpp
2) makefile
when I type make I get the following error:main.cpp:2:10: fatal error: 'SDL2/SDL.h' file not found.
here is a copy of my makefile
CXX = g++
SDL = -framework SDL2
CXXFLAGS = -Wall -c -std=c++11 -I ~/Library/Frameworks/SDL2.framework/Headers
LDFLAGS = $(SDL) -F /Library/Frameworks -F ~/Library/Frameworks/
EXE = SDL_Lesson0
all: $(EXE)
$(EXE): main.o
$(CXX) $(LDFLAGS) $< -o $#
main.o: main.cpp
$(CXX) $(CXXFLAGS) $< -o $#
clean:
rm *.o && rm $(EXE)
and here is a copy of main.cpp:
#include <iostream>
#include <SDL2/SDL.h>
int main(int, char**)
{
if (SDL_Init(SDL_INIT_VIDEO) != 0)
{
std::cout << "SDL_Init Error: " << SDL_GetError() << std::endl;
return 1;
}
SDL_Quit();
return 0;
}
I tried changing the #include to "SDL2/SDL.h" or just or any other possible combination. I had no problem setting it up through Xcode but can't figure out how to do it without using an IDE.
a second part of the question is:
if I wanted to include the frameworks in the project folder itself so I can later distribute the binaries to people who do not have SDL on their machines how would I do that?
thanks.

Answer 1

You were on the right track, but -F /Library/Frameworks needs to also be in the CXXFLAGS. The resulting commands should look something like:
g++ -Wall -F /Library/Frameworks -c -o main.o main.cpp
g++ main.o -o main -framework SDL2 -I /Library/Frameworks/SDL2.framework/Headers
Here's a simplified makefile that works for me on OSX 10.12.6:
CXX = g++
CXXFLAGS = -Wall -F /Library/Frameworks
LDFLAGS = -framework SDL2 -F /Library/Frameworks -I /Library/Frameworks/SDL2.framework/Headers
all: main
main: main.o
$(CXX) main.o -o main $(LDFLAGS)
obj/main.o : main.cpp
$(CXX) $(CXXFLAGS) -c main.cpp -o main.o
clean:
rm main.o main

if you go into
/Users/path/where/i/unzipped/SDL2-2.0.5
and run
sdl2-config --cflags --libs
it prints out the header include path and library path SDL
The full generic build probably looks something like:
g++ -std=c++11 main.cpp -o main.exe `sdl2-config --cflags` `sdl2-config --libs`
which you can translate into your make file if you like
