create_app crashes with 'Error: export ordinal too large: 73406' on Julia v1.10-rc1

[dustyirwin]

Hello, I am experiencing an error when attempting to run:

create_app("MyProj","MyProjCompiled", precompile_statements_file="precompile.jl", include_lazy_artifacts=false, incremental=false)

which eventually throws the error below on (what appears to be) one of the final steps of the compilation process:

... /.julia/artifacts/fdff308295487f361ef6e8dc2d27f5abe8a6eee9/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: Error: export ordinal too large: 73406 collect2.exe: error: ld returned 1 exit status

I do not get this error when incremental=true and the process completes successfully. After some Googling, it appears this error has something to do with exporting too many symbols for a 32-bit Int. I don't know if this is related, but I was not getting this error before installing MSYS2 and Glade3 for Windows for some Gtk development related to this project....

Any ideas?

it appears this error has something to do with exporting too many symbols for a 32-bit Int.

I'm not sure, the number 73406 obviously may come from Int32 or Int64, possibly more likely, but will not fit into UInt16:

https://stackoverflow.com/questions/47135973/error-export-ordinal-too-large-104116

The maximum ordinal number is defined by the Microsoft PE and COFF format. It is a 16-bit integer with a maximum of 65535.

I don't know the workaround here, other than incremental=true. At least that always works until you have a really huge project? I think it's simply not possible to make huge EXE files, i.e. with many methods, then you need to split projects up into DLLs. etc.

I think it's just an inherent limitation of Windows .exe programs, and I'm not sure if there's a similar limitation for other platforms e.g. Linux too, ELF format. You could try to compile a Linux program, and those actually work in Windows under WSL2...

Thanks for your response--UInt16 makes more sense :)

I'm targeting Windows for distribution since this is a gaming project using SimpleDirectMediaLayer.jl, but I may try compiling on Linux as a test. For the time being, I'll try trimming out any libs that aren't absolutely necessary.
