error: C1060: compiler is out of heap space

[MasterBlade]

I'm switching from MinGW to MSVC and found a lot of problems.

This program won't compile and C1060 error message appeared. What should I do?

I tried to add /Zm to the compiler. It will compile but nothing happens after that. No application comes out.

No application comes out

Then there should be an error

I didn't see any error message.

The code was alright when I use MinGW.

I have only 12 MB in the resource qrc file. I don't know why heap space is used up. I have 32GB mem.

OK Just to make sure I'm doing right. Is it correct to set the parameter here? I found that whatever I input here, the program compiles but nothing comes out.

@MasterBlade Compiler flags are set in pro file via QMAKE_CXXFLAGS
See http://doc.qt.io/qt-5/qmake-variable-reference.html

I tried
QMAKE_CXXFLAGS += /Zm

with different Zm values from 10 to 1000. Still the same problem.

It only mentions that qrc_options.cpp has this problem. Is there anything wrong with QRC files?

@MasterBlade Try to split your resource file smaller ones. I already had a similar issue and I fixed it with this solution.

This last post of this thread from stackoverflow gave me the right direction:
"Qt resources are processed by resource compiler and .cpp file is generated for each .qrc file. I suppose your generated .cpp file is huge (should be more than 30MB) and VC compiler just can't compile such huge source file."

Use externally built resources, don't just compile 12MBs of stuff into the executable/library. You can add it as a pre-build step in creator or as an additional target in the .pro file if you wish (a bit more complicated).

Thanks for the reply. Sorry I was busy these days.

I tried rcc command to turn the qrc file to rcc one. But the same problem happened again.

But strangely when I switch to Release mode everything went alright.

I also checked the qrc_options.cpp file it's 60.6 MB. I agree it's a little big but it's hard to believe MSVC 2017 doesn't support a file like this size. I heard it's made for big projects.

EDIT: I deleted old files and rebuilt the project. No errors this time. Thanks for the help.
