I have found the libtcc from https://github.com/TinyCC/tinycc to be absolutely fantastic. I'm using it to instantaneously compile the C output from my hobby language to create a repl. Once I had the compiler in good shape it allowed me to create a 100% compatible interpreter for (basically) free.
The libtcc API is minimal. For my needs that has been 100% sufficient and a pleasure to work with.
