fatal error C1060: compiler is out of heap space (again)
-
@Sprezzatura That's not what I asked. I didn't ask which file the error message points to, but rather during the compilation of which of your project files does the error happen? In C++ each project source file is compiled separately as a different compilation unit, re-parsing the header files (unless using pch).
Just post the entire build output if you don't know.
@IgKh Sorry, it looks like the error arises when compiling the first 21 .CPP files. Then the next 7 .CPP don't have the error. Then I see:

@Christian-Ehrlicher I am using a 64-bit compiler. Compiling for 64-bit executable.

If you compile in release mode, do you still get the same compiler error?
(Also, when compiling in debug mode, try removing that -FS option.)@hskoglund I get the same errors in Release mode.
The "/FS" is generated by Qt, not sure how to suppress it.
"/FS-"? -

What does 'where cl' prints out?@Christian-Ehrlicher Not sure where to enter "where cl". The Terminal Window returns:
INFO: Could not find files for the given pattern(s)The compiler I am using, according to the "Manake Kits" section, is:
Microsoft Visual C++ Compiler 17.12.35527.113 (amd64)
Not (x86), not (amd64_x86), not (x86_amd64), nor anything containing "arm".
To reiterate, it compiles successfully under Qt 5.15 + VS 2019.
BTW thank you for your help and patience :o)

where cl.exe@Christian-Ehrlicher I've found the culprit. If I include the following in the .PRO file:
QMAKE_CFLAGS += -Zc:__cplusplus QMAKE_CFLAGS += -permissive-It compiles successfully with Qt 5.15
However, when I include this to the .PRO file:QMAKE_CFLAGS += -std:c++17 QMAKE_CFLAGS += -Zc:__cplusplus QMAKE_CFLAGS += -permissive-even Qt 5.15 fails with the "Out of Heap Space" error.
If I remove this line and try to compile with Qt 6.9, I get:QMAKE_CFLAGS += -std:c++17"Qt requires a C++17 compiler, and a suitable value for __cplusplus. On MSVC, you must pass the /Zc:__cplusplus option to the compiler"Why would this option cause the Out of Heap Space error? Are there other options I need to add?

You have to call it in the console where you build you Qt... you are using a 32bit compiler.

The solution was to upgrade from VS 2022 ver. 17.13, to ver. 17.14.
I tried getting VS to update itself, but it locked up and wiped itself. I had to download and re-install VS 17.14.Here's the kicker: I got the suggestion from OpenAI/ChatGPT!
I'm an AI skeptic, but I have to give credit where it's due.
Also, ChatGPT suggested "-bigobj", but that didn't make a difference.
A sincere thanks to Christian and hskoglund from a 77-year old, half-blind hack :o)

Just as an aside (since I'm a little late to the party): You should turn on C++17 in the .pro file with the line
