[R-SIG-Mac] compilation problem

[Kenneth Knoblauch]

Hi,

When compiling packages with C/Fortran code, I'm frequently getting the
following sort of error at the stage of testing if package can be 
installed
from temporary location:

** testing if installed package can be loaded from temporary location
Error: package or namespace load failed for 'akima' in dyn.load(file,
DLLpath = DLLpath, ...):
unable to load shared object
'/Users/ken/Library/R/x86_64/4.2/library/00LOCK-akima/00new/akima/libs/akima.so':
dlopen(/Users/ken/Library/R/x86_64/4.2/library/00LOCK-akima/00new/akima/libs/akima.so,
6): Symbol not found: ___addtf3
Referenced from: /usr/local/lib/libquadmath.0.dylib
Expected in: /usr/local/lib/libgcc_s_x86_64.1.dylib
in /usr/local/lib/libquadmath.0.dylib
Error: loading failed
Execution halted
ERROR: loading failed

Any suggestions about how to fix this?  If it is a PATH problem, how do 
I set that so that it is correct when I start up R?

Thank you.

best,

Ken
