make dmg throws error #29

Closed mehulmpt closed 6 years ago

mehulmpt commented 6 years ago

My model: MacBook Air Early 2015 Version 10.13.2 When I do make dmg after cloning the repo and cd-ing into it, it throws the following output:

dev@mehulmpt:~/screenresolution$ make dmg

Subsequent calls to make dmg throw the following errors:

dev@mehulmpt:~/screenresolution$ make dmg
clang   -arch i386 -arch x86_64 -framework Foundation -framework ApplicationServices main.o cg_utils.o -o screenresolution

make: *** [screenresolution] Error 1

What should I do?

mehulmpt commented 6 years ago

Fixed this by adding:

#ifndef MIN
#define MIN(a,b) ((a)<(b) ? (a) : (b))
#define VERSION "1.7dev"
#endif

to version.h file
