Just a dumb question: can you successfully 'make', and create the
library using Unix tools directly from a bash window?
Hello,
I'm using R 2.8.0 on a Macbook Pro running Tiger on it.
I have a simple C file named hello.c and when I try to generate the .so
file like that:
$ R CMD SHLIB hello.c
I get the following output:
gcc -arch i386 -std=gnu99
-I/Library/Frameworks/R.framework/Resources/include
-I/Library/Frameworks/R.framework/Resources/include/i386
-I/usr/local/include -fPIC -g -O2 -c hello.c -o hello.o
gcc -arch i386 -std=gnu99 -dynamiclib -Wl,-headerpad_max_install_names
-mmacosx-version-min=10.4 -undefined dynamic_lookup -single_module
-multiply_defined suppress -L/usr/local/lib -o hello.so hello.o
-F/Library/Frameworks/R.framework/.. -framework R -Wl,-framework
-Wl,CoreFoundation
/usr/bin/libtool: for architecture cputype (16777223) cpusubtype (3)
object: /usr/local/lib/libgcc_s.10.4.dylib malformed object (unknown
load command 4)
make: *** [hello.so] Error 1
What is this error? How can I fix it?
Thank you
Thibault

I think you need to update your Xcode. What version is it, and how does
it compare with the FAQ's prescriptions?
