fontconvert compilation error on MacOS Sonoma M1 #447

Open mitch-spec opened 5 months ago

mitch-spec commented 5 months ago

I am trying to compile fontconvert on MacOS Sonoma M1. freetype 2.13.2 is already installed and linked via brew.

Compiling fontconvert throws the following error.

make fontconvert
gcc -Wall -I/usr/local/include/freetype2 -I/usr/include/freetype2 -I/usr/include fontconvert.c -lfreetype -o fontconvert
fontconvert.c:22:10: fatal error: 'ft2build.h' file not found
#include <ft2build.h>
         ^~~~~~~~~~~~
1 error generated.
make: *** [fontconvert] Error 1

When i am adding homebrew's location of freetype there's this error:

make fontconvert
gcc -Wall -I/usr/local/include/freetype2 -I/usr/include/freetype2 -I/usr/include -I/opt/homebrew/include/freetype2 fontconvert.c -lfreetype -o fontconvert
ld: library 'freetype' not found
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [fontconvert] Error 1

Do you have any idea how to resolve the issue?

It compiles as soon as i am adding the following: CFLAGS = -Wall -I/usr/local/include/freetype2 -I/usr/include/freetype2 -I/usr/include -L/opt/homebrew/opt/freetype/lib -I/opt/homebrew/opt/freetype/include/freetype2 -I/opt/homebrew/opt/libpng/include/libpng16

I figured it out with

freetype-config --cflags
freetype-config --libtool
freetype-config --libs
