…ment (if set) This is useful for compiling against a non-default Tk when the flags -tkdefs/-tklibs cannot be set explicitly for some reason. I.e. when installing via opam (and in particular on macOS with a homebrew installation of tcl-tk). For instance, do: $ export TK_DEFS='-I/usr/local/Cellar/tcl-tk/8.6.13_5/include/tcl-tk' $ export TK_LIBS='-L/usr/local/Cellar/tcl-tk/8.6.13_5/lib -ltk8.6 -ltkstub8.6 -ltcl8.6 -ltclstub8.6' before $ opam install labltk See also garrigue#18

On macOS, when I installed using "opam install labltk" this linked against Apple's version of Tk which honestly isn't very good.
To use the better version I installed using "brew install tcl-tk", I had to run "opam uninstall labltk" again (which probably left its dependencies in place), then the following commands in a git clone of this repo (these are a slightly-extended version of what "opam show --raw labltk" gave):
./configure -use-findlib -verbose -installbindir $HOME/.opam/5.0.0+flambda/bin -tkdefs -I/opt/homebrew/opt/tcl-tk/include -tklibs -L/opt/homebrew/opt/tcl-tk/lib -tk-no-x11 make library opt make installThis worked, but I was wondering if there was a nicer way to do this with some options to opam?
If it helps, you can set
PKG_CONFIG_PATH=/opt/homebrew/opt/tcl-tk/lib/pkgconfig:$PKG_CONFIG_PATHthenpkg-config --cflags tkgives the required value for -tkdefs above; andpkg-config --libs tkgive the equivalent of LDFLAGS in make (i.e. library search directory for -tklibs and required libraries).The text was updated successfully, but these errors were encountered:
