Question

I use Qt for C++ development, and today I produced a .vcproj file from a .pro file.

I noticed under the vcproj project properties, Qt added this flag into the C/C++ -> Command Line -> Additional Options

-Zm200

What is -Zm200?

Was it helpful?

Solution

-Zm is Specify Precompiled Header Memory Limit (more info here). It limits the amount of memory the compiler can allocate for processing precompiled headers. For Visual C++ 2008, -Zm200 means limit to 150 MB.

OTHER TIPS

This limits the maximum heap size for the compiler according to this article. So this doesn't affect your program at all
