Using latest OpenDylan (2020.1)

[Gareth Baker]

Hi,

Finally worked out how to get my system to find the clang in OpenDylan first (I get a segmentation fault if it tries to use clang v12). I now get an interesting error message:

dyld: Library not loaded: /Users/housel/obj/x86_64-apple-darwin19.6.0/dylan/odbuild-2020.1/release/opendylan-2020.1/lib/libgc.1.dylib

  Referenced from: /opt/opendylan-2020.1/bin/dylan-compiler

  Reason: image not found

Humm... not sure how to get round that one :-)

Thanks

Gareth

How did you install dylan - from homebrew or by installing the tarball? I will do the same and see if I get the same error.

OK, I installed it and didn't get the same error. But I had a poke around at the exe

$ otool -L opendylan-2020.1/bin/dylan-compiler

so for some reason the path for libgc is not the same as the others and I guess the OS loader can't find it because you won't have that /Users/housel/...  path.

I don't get the same error because I have libgc installed system-wide (needed to compile opendylan myself, obviously) so the loader can find it on the system path

$ DYLD_PRINT_LIBRARIES=1 dylan-compiler
dyld: loaded: /tmp/opendylan-2020.1/bin/dylan-compiler
dyld: loaded: /private/tmp/opendylan-2020.1/bin/../lib/libdylan-compiler.dylib

I think the exes need to be recompiled, to reference libgc relative to the @rpath, like all the others. The actual library has been included in the tar file, but the loader doesn't find it.
