Hello, I compiled lyx 1.5.1 on SLES 9 and it seems to me that the qt4 include is missing at at least on place. Here is the error I got
$ ./configure --prefix=/afs/lyx-1.5.1/ --with-frontend=qt4 --with-qt-dir=/afs/qt-4.2.1/ [...] /bin/sh ../../libtool --tag=CXX --mode=compile g++ -DHAVE_CONFIG_H -I. -I../../src -I./.. -I../../boost -DQT_CLEAN_NAMESPACE -DQT_GENUINE_STR -DQT_NO_STL -DQT_NO_KEYWORDS -I/usr/X11R6/include -O2 -MT docstring.lo -MD -MP -MF .deps/docstring.Tpo -c -o docstring.lo docstring.cpp g++ -DHAVE_CONFIG_H -I. -I../../src -I./.. -I../../boost -DQT_CLEAN_NAMESPACE -DQT_GENUINE_STR -DQT_NO_STL -DQT_NO_KEYWORDS -I/usr/X11R6/include -O2 -MT docstring.lo -MD -MP -MF .deps/docstring.Tpo -c docstring.cpp -o docstring.o In file included from docstring.cpp:14: qstring_helpers.h:17:17: QChar: No such file or directory qstring_helpers.h:18:19: QString: No such file or directory In file included from docstring.cpp:14: qstring_helpers.h:30: error: syntax error before `const' qstring_helpers.h:42: error: syntax error before `const' qstring_helpers.h:49: error: `char_type' was not declared in this scope qstring_helpers.h:49: error: syntax error before `)' token qstring_helpers.h: In function `bool is_utf16(...)': qstring_helpers.h:52: error: `c' undeclared (first use this function) qstring_helpers.h:52: error: (Each undeclared identifier is reported only once for each function it appears in.) Does anybody have an idea where the right place would be to fix that? If yes, I am happy to test that.
