Cannot Build Qt5.14 from Git on Centos7.9
-
Hi everyone, I'm trying to build Qt5.14 on my new Centos7.9 virtual machine. To do that, I followed the instructions here. But at the building step (make -j$(nproc)), I got an error:

Please submit a full bug report, with preprocessed source if appropriate. See <http://bugzilla.redhat.com/bugzilla> for instructions. The bug is not reproducible, so it is likely a hardware or OS problem.I have already done this:
$ export LLVM_INSTALL_DIR=/usr/llvmand this:
$ ../qt5/configure -developer-build -opensource -nomake examples -nomake testsI repeated the whole process from scratch (by make clean and than make again) but nothing worked.
I also tried gmake and make other than make -j$(nproc)@kimi-raikkonen said in Cannot Build Qt5.14 from Git on Centos7.9:

What is the RAM size of your virtual machine?
Internal compiler errors are often caused by out of RAM. -

@jsulm It is 4096 MB.

I would try with more if possible.

@JoeCFD I followed the document, hence it is 7.3.1.

@jsulm I just increased the memory but every time I try, I get different errors. So, it fails to build Qt. I ordered a new 8 GB RAM. It will be 16 GB in total. I will try again then with even more memory.

I get different errors
Internal compiler errors or something else?

@jsulm Yes, I do get internal compiler errors. But also other errors like this, a syntax error which is so weird.

This looks like a typo. You can check what is in line 142 in qdebug.h
How did you get Qt source code? -
First, I cloned Qt 5 git repo, then checked out the version (5.14) and finally did that:
$ perl init-repository --module-subset=default,-qtwebengine,-qtandroidextras,-qtmacextras,-qtpurchasing
