This is necessary for building FEX packages that contain some initial thunk libs.
Gives an initial foothold for a default location for the host and guest thunk folders
This was a missing feature that I had skipped previously.
Before this commit, each layer would overwrite all previous environment variables if they had anything defined.
After this commit, the layers will now merge in priority order.
Meaning if a higher priority layer has the same environment variable defined, it will overwrite that specific variable
Ending up with a superset of all the layer's environment variables now.
This is a helper program to execute a bash command through FEX.
Works around an edge case of
eg:
FEXInterpreter /bin/sh -c "echo A"
versus
FEXBash "echo A"
Argument expansion ends up being a pain point
This isn't currently used but will be very shortly
Useful for debugging but we need to be silent by default now.
Without this anything that checks stdout output of applications from bash would fail
Steam with lspci, lsusb, uname, etc
Notably this allows applications to work that don't require the namespace but check up front if they are able to clone with it.
Civ 6's launcher checks this as an example
Leafs come from ECX but only some CPUID functions support this.
This adds the initial infrastructure but doesn't yet add support for the CPUID functions to consume the leaf.
This takes the changes from #829 and moves it to the correct location to be picked up from any loader.
This also fixes#873.
Expands the config paths. Anything that has ~ or is relative will be converted to an absolute path.
Ubuntu's x86_64 rootfs does a soft link from `/lib64/ld-linux-x86-64.so.2` to an absolute path of `/lib/x86_64-linux-gnu/ld-2.32.so`
Our frontend ELF loader logic would resolve this symlink to be just `/lib/x86_64-linux-gnu/ld-2.32.so` which would then fail.
Adds some additional logic to our frontend that if the symlink ends up being a softlink to an absolute address then it'll first resolve that symlink.
Then combines rootfs + absolute path. If that still fails then it'll fall down the regular linker path, which could still find the linker on the host side.
This is all a bit of a kludge to just work around Ubuntu doing an absolute address rather than a relative one.
Fixes#869
This was previously just some default values that I put in as placeholder
Now that we actually have defaults configured somewhere, use those.
Fixed#874
