Project ERROR: Unknown module(s) in QT: webkitwidgets
(6 answers)
Closed 8 years ago.
I'm trying to use MXE (with help from this tutorial), and I'm getting this error at the qmake && make step:
Project ERROR: Unknown module(s) in QT: webkitwidgets".
What does this mean and what can I do?
As per this similar answer, try installing the corresponding package. Assuming you have a Debian-based system, this is done by entering the following command in a console:
sudo apt-get install libqt5webkit5-dev
Unfortunately you're out of luck because recent versions of MXE do not build webkit. Apparently it has symbol conflict with the Qt script library, so the static build is impossible. Use the older MXE version, and don't forget to enable building the webkit in the src/qt.mk file.

I recently installed the Scilab 6.1.0 on my Ubuntu 18.04 virtual machine on my windows pc. I am able to use the editor but cannot seem to load the Fossee Optimisation Toolbox. It installs successfully but shows the following error when restarting and trying to load the toolbox. I have already tried reinstalling Scilab and ubuntu. Can someone tell me how to resolve this?
atomsLoad: An error occurred while loading 'FOT-0.4':
exec: error on line #61: "link: The shared archive was not loaded: libquadmath.so.0: cannot open shared object file: No such file or directory"1
FOT is built using gfortran, and the missing library is one of its libraries. Scilab uses also gfortran and is including the corresponding libraries. But there is likely a version number mismatch, i.e. FOT has been built with a more recent version of gfortran. Installing a system wide gfortran with sudo apt-get install gfortran will probably install the version you need.

error: Unable to find vcvarsall.bat

Closed 3 years ago.
I am trying to install pyroms (https://github.com/ESMG/pyroms)
I am using python 3.6
when I write the "python setup.py build"
I get this error message:
error: Unable to find vcvarsall.bat
Usually, this error occurs when in your PATH somebody cannot locate vcvars.bat. This comes with Microsoft SDK. Double check that you have rge SDK installed (whatever version). Alternatively, you can try to manually invoke the "visual studio xxx command prompt" (where xxxi the architecture you are running the program. This is found in the program files start menu, after installing the SDK) and then invoke your software.
Usually these steps solve the issue.
I'm a newbie trying to install gearman on windows through cygwin using the tutorial here: http://www.phpvs.net/2010/11/30/installing-gearman-and-gearmand-on-windows-with-cygwin/
I need to install gearman to develop on my windows 7 laptop.
I've installed libevent in my C:\cygwin\libeventInstall directory but when I do a ./configure on gearman it gives me the error: configure: error: Unable to find libevent
I've read that I need to install libevent-devel. I don't know what libevent-devel is and how I go about installing it through cygwin. I've found a bunch of .rpm install files for libevent-devel but I don't think I can install that on windows. I've also found a libevent-devel-2.0.11-1.tar.bz2 but it contains a bunch of header files and no configure file. There doesn't seem to be any documentation on exactly how to install libevent-devel on cygwin.
Been stuck for a few days. Any pointers would be helpful. Thanks!
You need to build LibEvent, it is not included in Cygwin. I haven't tried this, but a google search led to the following instructions:
you need
http://win6.jp/Cygwin/cygwin-1.5.25-15-ipv6-0.22.zip
http://monkey.org/~provos/libevent-1.4.9-stable.tar.gz
unpack cygwin-1.5.25-15-ipv6-0.22.zip into you cygwin folder about this files read site http://win6.jp/Cygwin/
in libevent http.c file add line ---> #define EAI_SYSTEM 11
now install libevent
./configure
make
make install
I also found this SO thread interesting since the Libevent devs were commenting.
Gave up on using cygwin. Tried a reinstalling libevent as per the above and re-running gearman ./configure and the "configure: error: Unable to find libevent" persists.
Took James Butler's advice and am using virtualbox instead. Thanks.
I'm trying to build and install the ZeroMQ libraries (2.1.11 cloned from GitHub) under Cygwin (on a Windows 7 system).
configure gives me this error message:
configure: error: cannot link with -luuid, install the e2fsprogs
package
which persists even after I install e2fsprogs (1.41.14-1).
Is this a sign that ZeroMQ needs a real Ext2 file system? Where did I go wrong?
You need to install the libuuid-devel package. (When getting a linker error about -lxyz, searching http://cygwin.com/packages for libxyz usually does the trick.)
I have installed a bunch of qt packages - qt, qt-devel, qt4, qt4-devel, sip but can't get latest PyQt4 to compile.
I've pointed the configure script at my qt4lib as such
python configure.py -q /usr/lib64/qt4/bin/qmake --verbose
but getting errors like
DBus v1 does not seem to be installed.
cfgtest_QtHelp.cpp:1:25: error: qhelpengine.h: No such file or directory
sip: /mnt/hgfs/rnp_repos/PyQt-x11-gpl-4.8.1/sip/QtCore/qabstractitemmodel.sip:156: syntax error
Error: Unable to create the C++ code.
EDIT: Found out that SIP v4.11.2 is required for PyQt 4.8 but still can't make without errors. At least python configure.py finishes now.
Any tips?
Grab the PyQt4 SRPM from Fedora and rebuild using mock. You may need to look a few versions back for one that will compile against the version of Qt 4 in CentOS.
I've just successfully compiled PyQt 4.8 on Centos 5.5. I went down the route of building Qt4 from source - using qt-everywhere-opensource-src-4.7.1.tar.gz from Nokia.
Had to obtain various *-devel packages before Qt's ./configure would complete - see http://doc.qt.nokia.com/4.7/requirements-x11.html (don't worry about the version numbers being slightly lower than required).
Also I used Python 2.6 from the EPEL 5 repository (python26-devel). Just remember when building PyQt to run python26 configure.py (and not the default Python). I don't know if this will improve your mileage in building PyQt but we're porting an application from Windows which was already using 2.6 so this route was necessary for me.
Not going to post my entire .bash_history here (much trial and error!) but if you're trying this and get stuck please ask a question.
