Linux - building from source with GCC giving different segfault errors, Clang also fails #81490

Closed ACDouble closed 5 months ago

ACDouble commented 1 year ago

Godot version

4.1.1

System information

Linux Mint 21

Issue description

Following the documentation https://docs.godotengine.org/en/latest/contributing/development/compiling/compiling_for_linuxbsd.html#doc-compiling-for-linuxbsd , I've installed all the recquired packages, cloned the repo and ran scons platform=linuxbsd

At first, everything was running smoothly, until I was hit with the following error:

[Initial build] Compiling thirdparty/glslang/glslang/MachineIndependent/intermOut.cpp ...

scons: *** [modules/gdscript/gdscript_parser.linuxbsd.editor.x86_64.o] Error 1
scons: building terminated because of errors.
[Time elapsed: 00:02:13.891]

I've opened the offending file, and this is how it was;

template <class T>
bool Vector<T>::push_back(T p_elem) {
    Error err = resize(size() + 1);
    ERR_FAIL_COND_V(err, true);
    set(size() - 1, p_elem);

    return false;
}

I've removed the empty line before the return and ran the scons again. This time, I got a segfault at a different place:

scons: *** [modules/gdscript/register_types.linuxbsd.editor.x86_64.o] Error 1
scons: building terminated because of errors.
[Time elapsed: 00:00:57.801]

Simply running the scons again, without doing any modifications to that /core/object/object.h, I was met with yet another segfault, this time pointing to /core/object/object.h:496

Running yet another time, without any modifications to the code, this showed up:

[Initial build] Compiling thirdparty/pcre2/src/pcre2_convert.c ...
{standard input}: Assembler messages:
{standard input}: Internal error (Segmentation fault).
Please report this bug.

[Time elapsed: 00:01:47.614]

Since a cursory google search showed several posts and topics pointing to segfault errors with GCC unrelated to Godot, I've decided to run scons platform=linuxbsd use_llvm=yes to compile using Clang, as noted in an info box on the docs.

After roughly 8 minutes, with everything working fine thus far, the compilation failed with the following error

[Initial build] Compiling editor/register_editor_types.cpp ...

Only added the first Clang failure files because I kept getting an error with Github trying to upload the second one

kxn commented 1 year ago

internal compiler error at compiling often indicates unstable hardware. Please try on another computer

akien-mga commented 5 months ago

As pointed out by @kxn, this is likely a hardware failure. Linux Mint 21 seems to provide GCC 9 which is working fine otherwise in my tests (and many users compiling on Ubuntu 22.04 LTS), and it failing similar with Clang further confirms that it doesn't seem to be a compiler issue, but something specific to your hardware or system.

Closing as this isn't something we can solve in Godot.
