Requirements

To compile ChessX, you need at least Qt5.13. You will also need to download ChessX source code, as described in the download section.

Compilation

Compiling the source is simple. Just unpack the sources, go to source directory (chessx) and execute:

lupdate chessx.pro
qmake
make

If you receice an error in make related to multimedia, you can comment out the line CONFIG += sound in chessx.pro and call make again.

If the compilation is successful you should be able to run ChessX executable in release, debug or static subdirectory. It is called:

To enable debugging, you need to pass debug) variable to qmake:

qmake -recursive -after CONFIG+=debug

To enable static linking, you need to pass static) variable to qmake:

qmake -recursive -after CONFIG+=static

Static Linkage with Qt requires that you build a complete set of static Qt libraries. See the Qt homepage.

Every once in while Apple updates Xcode. ChessX usually won't compile afterwards:
Change the line

QMAKE_MAC_SDK = macosx10.11

to the current Apple SDK, call qmake and make afterwards.
