I cannot compile chessx since mid august. Maybe the file textbrowserex.h is not under version control. Here is the error message i got.
In file included from src/gui/playerlistwidget.cpp:6:0:
src/generated/ui_tagdetailwidget.h:26:27: Schwerwiegender Fehler: textbrowserex.h: Datei oder Verzeichnis nicht gefunden
Kompilierung beendet.
r1540 is the last revision without this error.
TextBrowserEx is part of the repository as of version 1542, see https://sourceforge.net/p/chessx/code/HEAD/tree/trunk/src/gui/TextBrowserEx.h
Perhaps you need to call svn update or qmake manually.
Also, if you are using a newer Qt release (Qt4.8 or Qt5) you need to manually erase all generated folders before calling quake, as otherwise Qt4 and Qt5 generated files from two locations become mixed up.
I tried a little more. I solved the problem by replacing
"textbrowserex.h" by "TextBrowserEx.h" in src/gui/tagdetailwidget.ui line 87.
I use Ubuntu. Are you using Windows? As far as i know windows filesystem is not case sensitive while unix is.
