It also generates some fp.xxx files under ~/.fp/. I hope they are for the command line version.

Does that mean that the I could also use make install INSTALL_PREFIX='~/LazarusInstalls/fpc240' command to install all the fpc versions into the same directory without their executable's clashing? I take it that the 'bin' folder in the INSTALL_PREFIX contains utilities which can be shared among the different installations, and that the 'share' folder will also have different docs for the versions. > Regards, > Sven > > -- > _______________________________________________ > Lazarus mailing list > [email protected] > http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus > -- Frank Church ======================= http://devblog.brahmancreations.com
