Hi,
Is the current version of Qt in rawhide threading enabled? I'm trying to
compile some of the threading examples in the C++ GUI Programming With
Qt3 book and get the likes of this out
transactionthread.h:64: error: expected class-name before ‘{’ token
transactionthread.h:74: error: ‘QMutex’ does not name a type
transactionthread.h:64: error: expected class-name before ‘{’ token
transactionthread.h:74: error: ‘QMutex’ does not name a type
transactionthread.h:64: error: expected class-name before ‘{’ token

transactionthread.cpp:68: error: ‘QMutexLocker’ was not declared in this

transactionthread.cpp:68: error: expected `;' before ‘locker’
transactionthread.cpp:70: error: ‘running’ was not declared in this

transactionthread.cpp:71: error: ‘start’ was not declared in this scope
transactionthread.cpp: In member function ‘void

transactionthread.cpp:79: error: ‘mutex’ was not declared in this scope
transactionthread.cpp: In member function ‘void
TransactionThread::setImage(const QImage&)’:
transactionthread.cpp:106: error: ‘QMutexLocker’ was not declared in
this scope
transactionthread.cpp:106: error: expected `;' before ‘locker’
transactionthread.cpp: In member function ‘QImage
TransactionThread::image()’:
transactionthread.cpp:112: error: ‘QMutexLocker’ was not declared in
this scope
transactionthread.cpp:112: error: expected `;' before ‘locker’
This kinda indicates that threading is not enabled.
qmake is also broken. There is a .pro file in the directory which looks
like this
######################################################################
# Automatically generated by qmake (1.07a) Mon Jan 30 22:10:55 2006
######################################################################
TEMPLATE = app
INCLUDEPATH += .
# Input
HEADERS += imagewindow.h transactionthread.h
INTERFACES += resizedialog.ui
SOURCES += imagewindow.cpp main.cpp transactionthread.cpp
If I run
qmake -o Makefile imagepro.pro
All I get out is multiple lines of
QFile::open: No file name specified.
I'll bugzilla the qmake problem now, but can someone check the threading
issue?
If I add -DQT_THREAD_SUPPORT to the compile line (which is
g++ imagewindow.cpp main.cpp transactionthread.cpp -o imagepro
-DQT_THREAD_SUPPORT -I/usr/lib64/qt-3.3/include -L/usr/lib64/qt-3.3/lib
-lqt-mt
)
all I get is...

Which is *REALLY* puzzling!
