HtmlHelp lazarus / 33-macOS - Mac OS X ---------------------------------------------------------------------- kpeters58 · 2016-03-29 17:15 Should I be able to use HtmlHelp under OS X? I see that htmlhelp.pp lives here on my Win box: C:\lazarus\fpc\2.6.4\source\packages\winunits-base\src When I run my code under OS X,  unit htmlhelp cannot be found. As always, thanks for all help! ---------------------------------------------------------------------- marcov · 2016-03-29 18:23 No. That is windows only code. FPC has CHM reading and lazarus has html rendering functionality, see the lhelp binary (the help of Lazarus itself)
