Compilation fail in macos monterey #10

Closed Reaster0 closed 2 years ago

Reaster0 commented 2 years ago

hey all! when i try to compile the tarball on macos monterey (arm) i get this undeclared identifier error, i suppose that it's just some type of variable to change for the macos compatibility

thanks for your work ;)

Try using Homebrew to get the latest ncurses package and then set:

export LDFLAGS="-L/opt/homebrew/opt/ncurses/lib"
export CPPFLAGS="-I/opt/homebrew/opt/ncurses/include"

It looks like the ncurses headers that come with your Mac don't have ncursesw (Unicode) support.

thank you! yes it work with the alternatives path, but it's kinda weird since i have already installed ncurses with brew in the opt dir sooo mm weird

Ok, someone sent me a pull request to update the build instructions for Mac. Hopefully, that will help others.

The issue was that you had the right headers, but your compiler/linker had to be manually pointed at them. They were defaulting to old headers that don't have Unicode support. Not sure why.
