Problems with relocatability

[guilhermebodin]

Hello,

I am trying to compile a project using MadNLP and PackageCompiler but it seems to have some relocatability problems. One colleague compiled in his machine a small example and the result was

This is MadNLP version v0.5.2, running with umfpack

EXIT: Optimal Solution Found.
The result is x = 3.9999999625061298

but in my machine gives the following error

PS C:\Users\guilhermebodin\Downloads\SimplePackageCompiled\bin> .\SimplePackage.exe
EXIT: Internal Error.
"C:\\Users\\louis.reumaux\\.julia\\packages\\MadNLP\\frGLf\\src\\..\\Project.toml": No such file

In this case, we are probably trying to read the Project.toml in runtime with some macro like @__DIR__ and it causes the error. This might be one possible issue.

Thank you for reporting this issue when using MadNLP with PackageCompiler. We haven't tested it yet, but this is also something in our todo-list.

Your guess is right, we are using @__DIR__ to read the Project.toml in order to infer the current version of MadNLP:
https://github.com/MadNLP/MadNLP.jl/blob/master/src/MadNLP.jl#L25

If that cause an issue with PackageCompiler, that should be fixed.
