Gabor,
this appears to be a known issue with lldb[1] - it doesn’t pass DYLD_*
variables to the executable anymore. You have to explicitly set it in lldb:
process launch -v
DYLD_FALLBACK_LIBRARY_PATH=/Library/Frameworks/R.framework/Resources/lib
or similar. Unfortunately, it means the wrapper can’t help here. You can get
the full setting from R if the above is not sufficient:
$ R --slave -e 'cat(Sys.getenv("DYLD_FALLBACK_LIBRARY_PATH"))'
/Library/Frameworks/R.framework/Resources/lib:/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/lib/server
Cheers,
Simon
PS: I have fixed the path for the nightly builds so it should be fixed in
tonight’s build, but the lesson is that the debugger does indeed have an
environment that is different from the actual executable.
