Portable executable (libs)

[DenBeke]

Are there tools available that make an executable portable by getting all the libraries, putting them in a folder and change the paths in the executable?

I want to be able to give a folder with an executable to someone else, who hasn't any developer tools/SDK's.

How to solve this?

Possibly with the patchelf tool: https://nixos.org/patchelf.html

You'll want to set the linker search path as in the example:

patchelf --set-rpath /opt/my-libs/lib:/foo/lib executable

You can list the libraries used by the executable if you don't already know them:

ldd executable

What does the tool actually do?
And I suppose I'll need to use otool on OS X, since ldd is for Linux?

Sorry, my whole answer was Linux specific... clearly wasn't paying enough attention.

I *think* install_name_tool is what you need on OS X:

install_name_tool -add_rpath /path/to/library/files executable

And I suppose I'll need to use otool on OS X, since ldd is for Linux?

Yep.

otool -L executable

Well it's good to have the Linux solution as well 🙂

I was hoping for a fully automated solution, but no problem, I'll try to specify all library paths manually...

You can just give the path to a directory containing the libraries - doesn't have to be each individual library.

Not enough coffee this morning, because I'm just not understanding your use case or need here. So, of course I'll just throw a bunch of junk at it: GitHub? I use Inno for Windows deployments and just create pkg ( dmg ) files for Mac deployments of software.
