PackageConfig lib linking issue

[dalu93]

Hi,

Thank you for this great library! I've start using it recently and I came across a small problem.
The library looks by default in the .build folder for the libPackageConfig.

So, when I run the following on my package, for example:

swift build && cd .build/debug/ && ./my-executable

The result is that it cannot find the .build folder. The same happens when moving the binary in the /usr/local/bin path, which sort of make it un-usable together with Mint

Is there any plan to overcome this issue? Is it even considered as an issue?
Thank you very much

I think it could look in a few different folders for a build directory (we did that with danger-swift for example)

I'd consider it an issue, they probably hardcode those build folders so can just make a list and look there?

This wouldn’t work in case PackageConfig is included as a dependency in the Package file. So would you recommend to install PackageConfig globally using mint, for example?

[dalu93]

On the same note, what I would expect from most of the people are the below steps:

1. Import PackageConfig as a dependency of their executable
2. Build the executable on top of that (and somewhere try to call getPackageConfig())
3. Take the executable binary and move it to a different folder (ex: /usr/local/)
4. When launching the executable, that would crash because the lib couldn't be found.

@dalu93 think i have an idea on how to make it work almost as you specified.

PackageConfig/Sources/PackageConfig/PackageConfig.swift

Line 18 in 33ea88f

Writer.write(configuration: self)

PackageConfig/Sources/PackageConfig/Writer.swift

Line 8 in 33ea88f

static func write<T: PackageConfig>(configuration: T) {

PackageConfig/Sources/PackageConfig/PackageConfig.swift

Line 17 in 33ea88f

public func write() {

I think modifying these methods to accept a list of path to search for dynamic libraries at run would suffice.
So that a library user would define search path for a dynamic library in the config as follows.

#if canImport(ExampleConfig)
import ExampleConfig

ExampleConfig(value: "example value").write(searchPaths: ["/usr/local/", ".build/debug", ])
#endif

Would try to implement when i have time. This would allow PackageConfig to also be installed system wide.
