-pthread havoc

[wysota]

What does it contain exactly?

[Cruz]

Here is my .pro file:

TEMPLATE = app
TARGET = MocapRobot
QT += core \
gui \
xml \
opengl
HEADERS += dynaped.h \
gait_modell.h \
kidsize.h \
mocaprobot.h \
fileloader.h \
landscape.h \
globals.h
SOURCES += dynaped.cpp \
gait_modell.cpp \
kidsize.cpp \
main.cpp \
mocaprobot.cpp \
fileloader.cpp \
landscape.cpp
FORMS += mocaprobot.ui
RESOURCES +=
CONFIG += console
LIBS += -LQGLViewer \
-lQGLViewer

[wysota]

What if you change this:

QT += core \
gui \
xml \
opengl

QT += core \
gui \
xml \
opengl

To copy to clipboard, switch view to plain text mode 

to this:

QT = core \
gui \
xml \
opengl

QT = core \
gui \
xml \
opengl

To copy to clipboard, switch view to plain text mode 

I doubt it will change anything but that would be a proper line in this case anyway.

This "-pthread" is probably coming from somewhere in your system. Are you using HP-UX? That's the only system that actually makes use of this flag, at least that's what g++ manual says.

You were right, the line doesn't change anything. I'm using Linux. I regenerated my Makefiles and I can see all the -pthread flags in the LIBS variable. I don't know how they get there though, it must be generated by qmake somehow.

[wysota]

Please run the following code from your console and paste the result:

cd /home/missura/qtsdk-2009.03/qt/mkspecs
grep -R "\\-pthread" *

cd /home/missura/qtsdk-2009.03/qt/mkspecs
grep -R "\\-pthread" *

To copy to clipboard, switch view to plain text mode

Here it is:

missura@shakey:~/qtsdk-2009.03/qt/mkspecs$ grep -R "\\-pthread" *
freebsd-g++/qmake.conf:QMAKE_CFLAGS_THREAD = -pthread -D_THREAD_SAFE
freebsd-g++/qmake.conf:QMAKE_LFLAGS_THREAD = -pthread
freebsd-g++34/qmake.conf:QMAKE_CFLAGS_THREAD = -pthread -D_THREAD_SAFE
freebsd-g++34/qmake.conf:QMAKE_LFLAGS_THREAD = -pthread
freebsd-g++40/qmake.conf:QMAKE_CFLAGS_THREAD = -pthread -D_THREAD_SAFE
freebsd-g++40/qmake.conf:QMAKE_LFLAGS_THREAD = -pthread
netbsd-g++/qmake.conf:QMAKE_CFLAGS_THREAD = -pthread
netbsd-g++/qmake.conf:QMAKE_LFLAGS_THREAD = -pthread
openbsd-g++/qmake.conf:QMAKE_CFLAGS_THREAD = -pthread
openbsd-g++/qmake.conf:QMAKE_LFLAGS_THREAD = -pthread
qws/freebsd-generic-g++/qmake.conf:QMAKE_CFLAGS_THREAD = -pthread -D_THREAD_SAFE
qws/freebsd-generic-g++/qmake.conf:QMAKE_LFLAGS_THREAD = -pthread
tru64-cxx/qmake.conf:QMAKE_CFLAGS_THREAD = -pthread
tru64-cxx/qmake.conf:QMAKE_LFLAGS_THREAD = -pthread

and also:

missura@shakey:~/qtsdk-2009.03/qt/mkspecs$ cat /proc/version
Linux version 2.6.24-27-generic (buildd@vernadsky) (gcc version 4.2.4 (Ubuntu 4.2.4-1ubuntu3)) #1 SMP Wed Jan 27 23:54:28 UTC 2010

In that case the "-pthead havoc" doesn't come from qmake but rather from something else installed on your system. As you can see qmake would insert such statements only on tru64 and various bsd systems. Please check your /etc/ld.conf.so.d and /etc/ld.so.conf files, maybe one of them contains such statements.

[Cruz]

Unfortunately there is nothing interesting there:

missura@shakey:~$ cat /etc/ld.so.conf
/lib/i486-linux-gnu
/usr/lib/i486-linux-gnu
/usr/local/lib
