I did copy gmp.pas to another folder and named it mygmp.pas, changed "$linklib
gmp.3” to "$linklib gmp.dylib” (just plain gmp did not work). Now examples
compile and run with the change to “uses mygmp” and adding opt/homebrew/lib to
the link search path.
So good to go.
For next release can we change the gmp.pas source to:
{$ifdef darwin}
{$linklib gmp.dylib}
{$endif}
That way folks can use the installed unit w/o changes (except to their lib
path).
Thanks!
