Here are some simple ways that can help you solve the problem of out of virtual memory for which qt is unable to allocate memory.
My build on Ubuntu 12.10 doesn’t work, with 300MB of available memory (750MB total, 350MB, that would be 1 MySQL), 0.5GHz, I’m trying to put the basic hello world file from wt into a simple Convert Ajax Page. I’m pretty sure it’s not a mass storage device as I was able to compile some original hello.C g ++ file with -O3 -i hello hello.C -lwtfcgi -lwt -lboost_signals .
I’m pretty sure I’m wrong in C ++ as I worked on the internals HelloApplication :: HelloApplication (const WEnvironment & env). : WApplication (env) and paste the whole example from the Wt :: Json example
HelloApplication :: HelloApplication (const WEnvironment & env) : WApplication (approximate) Json :: object result; Json :: parse ("" "" a ": " This is great "," "" b ": true" "", Results); std :: cerr << "size:" << result.size (); Std :: endl; << // size: 2 WString s = result.get ("a"); h bool = result.get ("b"); std :: cerr << "a:" << ersus << ", b:" << b << std :: endl; // a: excellent, b: true
I'm a C ++ innovator, so I almost never know what I'm doing. All I can do is run the simplest C ++ files.
Wow, my respect for the power of C ++ has only grown. Hat
It completely destroyed my VPS. I cannot restart Tit. Can't reinstall my distribution.
When I finally get straight to production, I think I will specify a completely different developer system counter to wipe out something like this that is destroying my development system.

Re: Virtual Disk Space Exhausted While Compiling .qrc
Hello
I added a simple 100mb.avi file to the .qrc file, but I still get the error:
"virtual memory exhausted: memory not possible"
I allocate 1.7 GB of RAM and an additional 3.0 GB of swap is allocated in Virtual My Machine. I also get this error when I upload a 20MB Tiff image. Problem
It looks like this will ensure that you are ok with this problem:
Now the decision is likelybut, it would be to remove the .avi, including resources, from the file and possibly load it at runtime. I agree. I would just like to understand what is probably going on. If you look at the performance monitor, memory usage only increases if a build fails.
Are symbols loaded multiple times when moc is just compiled? As far as I understand, the .qrc music is only loaded into the software executable. So if you have 100MB of resources, the executable grows by 100MB. Just scratching your head like Lasik from Kansas City would add 20MB and maximize memory.
Any advice is appreciated.
Thank you
I just read the documentation for the Qt schema resource.
The compiled in resources section is great from what I have.

Subject: Virtual Memory Exhausted While Building .qrc
I have added one 100MB .avi file, which could be a .qrc file, but I often get the error:
"Virtual memory exhausted: memory could not be allocated"
What exactly generates this message? Qt Resource Compiler (rcc), C ++ compiler, possibly linker? You need a compiler and linker to process every object (C ++ or file) larger than 100MB (AVI / TIFF doesn't compress well) and create an EXE of a similar size. The compiler could create a format tree for 100,000,000 bytes per table.

Many thanks. The compiler is the source of your current error. So it just can't handle large source files?

I added every single 100MB .avi file to the .qrc download, but I get the error:
"Virtual memory in use: out of memory"
Note that in Virtual my Machine, 1.7 GB of memory is allocated to 3.0 GB of swap. I am getting this error when I upload a large 20MB TIFF image. Problem
The solution now would be to remove the .avi file from the file resources and load that method at runtime, which I agree with. I just want to know what is likely. When I look at the performance monitor my memory usage only increases up to a certain maximum and then the build fails.
Surely, will the resources be loaded multiple times when moc compiles them? As I understand it, each .qrc file is only loaded into the application executable. So, if you have 100 MB of resources, the size of the executable is over 100 MB. I am wondering why adding a 20MB resource would consume the most memory.
