I want to compile opentracker(https://erdgeist.org/arts/software/opentracker) on my machine osx 10.9. when run "make" command I get this error:
cc -c -o opentracker.o -I../libowfat -Wall -pipe -Wextra -O3 -DWANT_FULLSCRAPE
opentracker.c
opentracker.c:25:10: fatal error: 'io.h' file not found
#include "io.h"
^
1 error generated.
make: *** [opentracker.o] Error 1
what is the problem? Is there any way to install io.h through homebrew?
