So I read the note on "PyQt 5.11 missing WebEngine modules" at https://www.riverbankcomputing.com/software/pyqt/download5. But it doesn't help me understand why, or what to do regarding the missing WebEngine modules? The only thing that works is to revert to PyQt 5.10.0 or use x64 version. Can anyone explain and help me understand how I am meant to continue using PyQt5 x86 when the modules I use are now missing in 5.11.x and there appears to be no resource to re-acquire them. Are the WebEngine modules no longer supported in 32 bit or something?
The problem is simple, PyQt5 uses the binaries provided by Qt, and currently Qt no longer provides binaries for 32 bits, only for 64 bits.
Can you use Qt WebEngine for 32 bits ?
Yes you can but you will have to compile Qt manually and the dependencies of Qt WebEngine, and after that you will have to compile PyQt5.

I am getting the below error when I try to execute the below line of code in my project. I added a 64 bit JDK to my project properties . I am using Intellij as my IDE
System.loadibrary(smsjavaagentapi)
Fatal Error: Exception from System.loadibrary(smsjavaagentapi) java.lang.unsatisfiedLinkError smsjavaagentapi.dll: Can't load IA 32 bit .dll on an AMD 64-bit platform
I think the problem is that I am using a 64 bit JVM and I am trying to run a 32 bit .dll. I don't have an option to install 32 bit JDK on my machine and add it to my project properties nor I can port the .dll to 64 bit . Is there a work around for this?
There is a limitation at the OS level which prevents a 32-bit shared library being loaded by a 64 bit process, so your options are
modify the OS to allow this (not easy)
migrate the DLL to 64-bit by recompiling it.
install a 32-bit JVM (easier)
download a 32-bit JVM and unpack it without install it. (doesn't require any special permission)
You might find you can get a version of IntelliJ which ships with a 32-bit JVM, or install another program which installs a 32-bit JVM and use just the JVM.
I have installed the standalone IDE for salesforce force.com platform. On trying to start the ide i am getting "JVM terminated. Exit Code=-1" error. Any idea what this error code means ?
This is a common loading error for force.com IDE.
There are different solutions. Try anyone of these:
A) Change the workspace location.
OR
B) (i). Install Eclipse 3.6 for Java Developers (Helios) from the link http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/heliossr2
Click your operating system from the window on your right.
(ii). Using the below link, follow the instructions to install Force.com IDE plugin for Eclipse 3.6 http://wiki.developerforce.com/page/Force.com_IDE_Installation_for_Eclipse_3.6
OR
C) In the default Force.com IDE install directory:
C:\Program Files\salesforce.com\Force.com IDE
Locate the config file:
forceide
And comment out the following at the end of the file (note the leading #):
#-vmargs
#-Dfile.encoding=UTF-8
#-Xms256m
#-Xmx1024m
#-XX:PermSize=128M
#-XX:MaxPermSize=512M
I hope it works now.
Cheers!
This could be because of various reasons. Say, if you do not have enough memory (RAM) as specified in config file(forceide.ini). As said in this link Force.com IDE – JVM terminated , probably reduce MaxPermSize in config file to say 256M and check.
This exact thing happened to me a few days ago.
My setup is:
Windows 7 64 bit
jre7 64 bit
Force.com IDE 64 bit
When I ran the java auto update to update my jre it installed the 32 bit version (a whole other gripe). So I manually downloaded the 64 bit version of the jre installed it over the top of the 32 bit version and the IDE started working again.
How to determine whether library is 32 bit or 64 bit from the library file ? I have installed gstreamer from ossbuild for this I know its 32 bit but suppose if someone else installs a library what is the way to find if it is compatible with 32bit or 64bit . Also are the format of the library similar or they differ?
When you said "Library", I guess you mean "runtime Library" aka. Dynamic-Link Library (DLL), is that correct?
In that case, this might be a duplicate of this question
I'm attempting to build a Linux browser plugin using Firebreath that runs on 32bit and 64bit Linux.
In my X11/projectDef.cmake I have
target_link_libraries(${PROJECT_NAME}
${PLUGIN_INTERNAL_DEPS}
"${CMAKE_CURRENT_SOURCE_DIR}/lib/libOIS-1.4.0_32.so"
)
Currently I'm just manually changing that line switching 32 to 64 when I want to do a different build, so that's probably wrong. But my issue is that even when I build with the 32bit library and it compiles successfully, I get the following error when trying to load the plugin in Firefox:
$ firefox
LoadPlugin: failed to initialize shared library /home/daniel/.mozilla/plugins/npBoomstickJavaScriptJoystickSupport.so [libOIS-1.4.0.so: wrong ELF class: ELFCLASS64]
How do I set up my cmake to automatically include the correct library depending on the architecture? Is there a way to build both x86 and x86_64 simultaneously on the same machine? How do I get the plugin to load correctly or is there a way to further debug this problem?
As far as I know the only way to do a build for 32 bit on a 64 bit machine is to use cross compiling: http://www.vtk.org/Wiki/CMake_Cross_Compiling
I've never actually tried this, but inside CMake you can probably use the CMAKE_SIZEOF_VOID_P which will be 4 in 32 bit mode, 8 in 64 bit. You could add an if to your cmake script to set the correct binaries depending on the size of that.
I know that MAC OS X 10.5 comes with Apache installed but I would like to install the latest Apache without touching the OS Defaults incase it causes problems in the future with other udpates. So I have used the details located at: http://diymacserver.com/installing-apache/compiling-apache-on-leopard/ But I'm unsure how to make this the 64 Bit version of Apache as it seems to still install the 32 bit version.
Any help is appreciated
Cheers
Add this to your ~/.bash_profile which means that your architecture is 64-bit ant you’d like to compile Universal binaries.
export CFLAGS="-arch x86_64"
This page claims that a flag for gcc (maix64) should do the trick. Give it a whirl, and if you need any more help, post back here.
Be aware that you may run into issues with your apache modules. If they are compiled in 32-bit mode, then you will not be able to load them into a 64-bit apache.
I had this issue with mod_python, took a bit of thinking to figure out this was the reason.
Don't export CFLAGS from your .bash_profile or any other dot file. Your home directory could live on for decades, the system you're currently using is transient.
There's a guide on Apple's web site, Porting UNIX/Linux Applications to Mac OS X, that talks specifically about how to make autoconf and make and other similar build systems fit into the Mac OS X Universal Binary scheme. If you're going to build cross-Unix applications on Mac OS X, you need to read and understand this guide.
That said, I strongly question why you want to build Apache 64-bit. Just because Leopard can run 64-bit software doesn't mean you want all software on your system to be 64-bit. (It's not Linux.) In fact, virtually none of the software that ships with Leopard runs 64-bit by default, and most of the applications included with Leopard only ship 32-bit.
Unless you have a pressing need to run Apache 64-bit, I wouldn't bother trying to build it that way.
If you would have read a bit further on the same site there is some information on compiling Apache in 64 bits mode!
