PCK section missing from self compiled templates (Linux, linking with LLD)

[majenkotech]

Tested versions

4.3.dev HEAD

System information

Arch Linux

Issue description

When exporting with embedded PCK an error is produced saying the PCK section is missing. Probing the resultant executable file with objdump -x you can indeed see there is no pck section in the ELF file.

Steps to reproduce

This is with the MYSQL extension installed. To get it to compile on Arch I had to use LLVM and LLD, which may be the issue?

So... compile the templates with LLVM and LDD and examine the results to see if the pck section exists in them.

Minimal reproduction project (MRP)

No need for a project. Just compile the templates from the source tree with LLVM and LLD.

PCK section is not supported when linking with LLD, build process should print a warning: Warning: Creating export template binaries enabled for PCK embedding is currently only supported with GNU ld, not gold, LLD or mold..

I'm a bit confused, doesn't mold support embed pck? When exporting godot does prompt that the pck part can't be found, but the exported executable, runs all right.

If I remember correctly, the PCK section is not required to embed PCK, it can be simply appended at the end of the executable.

The same with LLD - it complains and "fails" the export, yet it has embedded the PCK and it runs.

It still fails in at least one way as it won't handle shared libraries if the embedding fixup fails

I'm facing the same problem I'm trying to export to windows both with embed pck on/off and it throws same error on run .exe
I'm using 4.3 dev

@imvenx That should be a different issue, this one is specific to Linux and clearly identified as related to how the binaries are compiled. It can't affect Windows which uses a different approach.
