[SOLVED] Fedora can't find libSDL2main.so (and doesn't need it): can I use one Makefile for Fedora and Ubuntu?

Issue

On Fedora, my command g++ main.cpp sdl2-config --cflags -lSDL2main -lSDL2 thinks that the SLD2main library is not available. It's right: other SDL2 libraries are in /usr/lib64; libSDL2main.so is not.

But I installed all apparently relevant SDL2 rpm's. Here's what the system tells me when I say yum install SDL2:

Package SDL2-2.0.12-1.fc32.x86_64 is already installed.
Package SDL2-devel-2.0.12-1.fc32.x86_64 is already installed.
Package SDL2_image-2.0.5-3.fc32.x86_64 is already installed.
Package SDL2_image-devel-2.0.5-3.fc32.x86_64 is already installed.
Package SDL2_mixer-2.0.4-5.fc32.x86_64 is already installed.
Package SDL2_mixer-devel-2.0.4-5.fc32.x86_64 is already installed.
Package SDL2_ttf-2.0.15-4.fc32.x86_64 is already installed.
Package SDL2_ttf-devel-2.0.15-4.fc32.x86_64 is already installed.

If I take the g++ option -lSDL2main out, the program links and runs.

But this is a problem. I want my Makefile to work on Unix systems generally. How can I do this -- use the same Makefile for RedHat/Fedora and Debian/Ubuntu?

Solution

You should be getting the linker flags from sdl2-config --libs, or pkg-config sdl2 --libs.
