Error when compiling Application in Release mode with MinGW Compiler (out of memory allocating 20479 bytes)

[Zain]

Hello all,

When I am trying to compile my desktop application in release mode using MinGW getting the only error is: "cc1plus.exe:-1: error: out of memory allocating 20479 bytes".

Application is properly compiling and running in debug mode.

I am using Windows7 and Qt 4.8.1 version.

Please help me to resolve this memory issue in release mode.

Thanks in Advance
Zain

Which version of MinGW are you using?
IIRC there have similar reports here at devnet. I might help to update to newest MinGW distribution. However, this means also that may have to recompile Qt.

Thanks Koahnig for quick reply.

Sorry but I am new in QT and not much aware with MinGW. Can you please tell me from where I can get version of MinGW?

I got this following info in mingw folder's manifest file.

mingwrt-3.15.2-mingw32-dev
mingwrt-3.15.2-mingw32-dll

One thing I would like to share that in my application is containing 5 classes of size 2-3 MB of each.Could it be cause of this problem?

And Is it possible to make deployment build of my application in debug mode using MinGW?
I made build debug mode but giving Qtcored4.dll error while I have added this dll in that folder.

It seems to be MinGW 4.4 based on your list. Possibly there is a mix, but I do not know all the details of MinGW myself. You can check the version of MinGW on the command prompt with "g++ --version".

MinGW 4.4 is outdated already for some time. Even though it has been used for the latest pre-build of Qt 4.8.4 available from the download page.

If you think of using Qt4 "here is wiki page":http://qt-project.org/wiki/Building_Qt_Desktop_for_Windows_with_MinGW helping in building Qt libs.
The "wiki on MinGW":http://qt-project.org/wiki/MinGW tells how to get the newest compiler.

It looks that you are starting with Qt. You might want to have a look at the alternative of using the "new Qt5 SDK":http://download.qt-project.org/official_releases/qt/5.0/5.0.2/qt-windows-opensource-5.0.2-mingw47_32-x86-offline.exe. It comes with Qt creator and also the newest MinGW compiler. This might save a bit of hazzle for you.
