fatal error C1060: compiler is out of heap space (again)

@Sprezzatura said in fatal error C1060: compiler is out of heap space (again):
Any suggestions?
Use a 64bit compiler even when you compile for 32bits.
@Christian-Ehrlicher I am using a 64-bit compiler. Compiling for 64-bit executable.

I'm converting a project that compiles without error under Qt 5, to Qt 6. I'm getting the
Compiler out of heap spaceerror.
I've researched the other posts about this error, and they don't fix the problem.
I've added "/Zm2000" to the compiler options. No go.
This error does not occur when compiling with Qt 5.
It fails with VS 2019 and VS 2022, Qt 6.6, and Qt 6.9.
There are no egregiously large .CPP files. The largest .CPP source file is 141KB or 4,412 lines.
The .QRC file includes fifteen .PNG files totalling 176KB.
I have 32GB of RAM.Any suggestions?

During the compilation of which file does the error happen? Or does it happen during the link phase?

Strangely, the error messages all point to Qt header files, which or course I have not altered or modified in any way:

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:

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-"? -

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.

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

You have to call it in the console where you build you Qt... you are using a 32bit compiler.
λ where cl C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.44.35207\bin\Hostx64\x64\cl.exe@Christian-Ehrlicher
[1] Here's what is displayed in the Compile Output window when I delete the "-nologo" option:Microsoft (R) C/C++ Optimizing Compiler Version 19.43.34810 for x64 Copyright (C) Microsoft Corporation. All rights reserved.Note the "x64".
[2] My .PRO file contains:
contains(QT_ARCH, i386) { message("32-bit" $$QT_ARCH $$QT_VERSION) } contains(QT_ARCH, x86_64) { message("64-bit" $$QT_ARCH $$QT_VERSION) }This is displayed in the Compile Output window:
Project MESSAGE: 64-bit x86_64 6.9.0[3] I tried creating a new Kit and adding a 32-bit compiler. Qt flat out rejected it.
[4] What does the "λ" lambda mean in your example?
When you say "the console where you build your Qt", do you mean the Terminal window in Qt Creator?
When I do that, I get:>where cl INFO: Could not find files for the given pattern(s).I'm using Windows.

You are using a 32bit compiler which creates 64 bit executables. Or you have very low ram on your system which I doubt.Qt Online Installer direct download: https://download.qt.io/official_releases/online_installers/

In my VS2002 installation there are 4 different cl.exe versions:
c:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.43.34808\bin\Hostx86\x86\cl.exe
c:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.43.34808\bin\Hostx86\x64\cl.exe
c:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.43.34808\bin\Hostx64\x86\cl.exe
c:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.43.34808\bin\Hostx64\x64\cl.exeTwo of them (the ..\Hostx86\x64\cl.exe and the ..\Hostx64\x64\cl.exe will show the same output:
"Microsoft (R) C/C++ Optimizing Compiler Version 19.43.34810 for x64" and both will compile and build 64 bit ..exe files for Qt6.So you have a 50% chance of running the correct compiler, i.e. the cl.exe in the subdirectory ..\Hostx64\x64

You are using a 32bit compiler which creates 64 bit executables. Or you have very low ram on your system which I doubt.@Christian-Ehrlicher I'm not launching this from the command line. I'm using Qt Creator, which automatically creates a stream of commands, including launching cl.exe, followed by a ton of parameters.
The output appears in the "Compile Output" window of the Qt Creator IDE. -

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)
