Hi-
I am building a package that includes C code. When I try to compile the source
files using SHLIB (or build the package using BUILD), it fails because it
builds for the wrong architecture. Specifically, SHLIB and BUILD specify "-arch
i386" by default on my machine. When I override and compile manually with
"-arch x86_64", it is fine. I'm unsure how to deal with this problem. Where are
the configuration files that SHLIB and BUILD are using that specify the
compiler and the architecture?
I'm using R v3.0.2 on OSX 10.7.5.
Would this have anything to do with settings in
/Library/Frameworks/R.framework/Versions/3.0/Resources/etc/Makeconf ? If so, I
see nothing in there about i386: rather, -arch x86_64 is specified.
Thanks in advance. Full error message below. I have the same issue if I just
compile with SHLIB and try to load them (though it's fine if I compile with gcc
-arch x86_64, then load the *.so files).
I'd also love to know how to configure things so that SHLIB and BUILD call a
particular compiler, and where I would add any path variables that need to be
added for this to work.
