Cannot compile (link) on FPC 3, Fedora, 64bit...

[3FLLC]

Obviously I am missing a package in the OS or something...

/usr/bin/ld: warning: link.res contains output sections; did you forget -T?
/usr/bin/ld: cannot find -lX11
/usr/bin/ld: cannot find -lXext
/usr/bin/ld: cannot find -lXft
/usr/bin/ld: cannot find -lfontconfig
colorwheel_test.lpr(27,1) Error: Error while linking

None of the examples compile, basically all saying they cannot link X11, Xext, etc. Does this mean I need to pull in the X11 dev package for Linux?

Hello.

Does this mean I need to pull in the X11 dev package for Linux?

Yes, because of some confusion in fpc, you need the "*-dev" packages to link the libraries.

See here: https://bugs.freepascal.org/view.php?id=32367

@graeme : Sorry, I could not resist. ;-)

Fred is 100% correct. The instructions to install the development libraries (for Linux) is included in the README.txt file included with FPC.
https://github.com/graemeg/fpGUI/blob/develop/docs/README.txt

See the section System requirements under Linux for more details.

@fredvs 👍 Many thanks for helping out with the support. It is much appreciated. :)

If you want to dynamicaly load the libraries used by fpGUI (and so no need to install *-dev), take a look here:
https://github.com/fredvs/dynx

(and particularly there; https://github.com/fredvs/dynx/tree/master/src/fpgui )
