stavromulabeta / ersatz Goto Github PK

I tried to compile this project on FreeBSD using the command line and following the instructions in the ReadMe. I had already installed the required libraries but got errors when I used the make command. I then tried with debugging flags and got the following:

$ make -d e cc ersatz.c -o ersatz sdl2-config --libs --cflags curl-config --libs --cflags xml2-config --libs --cflags` -l:libSDL2_ttf.so -l:libSDL2_image.so -Ofast -flto -s
ld: error: undefined symbol: backtrace

lto.tmp:(throw_error)

Stop.

Do you have any suggestions to get this code to compile? I would like to demo it on open evening in a week's time.
