Hi,

I have a UNIX-Solaris-Sparc-Studio 11 compilers question. Since it's not exactly a programming question, I'm posting it here instead of to the developers list.

Here's the relevant info:

1) I'm using SunOS 5.9 on a 32 bit machine without parallel processing. The chip is Sparc.
2) I've installed the Sun Studio 11 compilers.
3) I've successfully built and tested R 2.5.1 with Studio 11--all the make checks were successful as were my own tests.
4) The README to the Rmath standalone library warns that mlutils.c _cannot_ be compiled with Sun's cc compiler because it can't do compile-time floating point arithmetic. This is confirmed by the output I get when I run the make (after the full R package was built and installed):

(cd ../../include; make Rmath.h)
`Rmath.h' is up to date.
Copying source files
cc -I. -I../../../src/include -I../../../src/include -I./.. -I/usr/local/include -DHAVE_CONFIG_H -DMATHLIB_STANDALONE   -g -c mlutils.c -o mlutils.o
/usr/ucb/cc:  language optional software package not installed
*** Error code 1
make: Fatal error: Command failed for target `mlutils.o'
Current working directory /export/home/ploua/R_HOME/R-2.5.1/src/nmath/standalone
*** Error code 1
make: Fatal error: Command failed for target `static'

5) My question: Why does the full R package compile and run without difficulty using the same Studio 11 compilers? I'd like to be able to build the Rmath standalone library without mixing compilers on this machine, i.e., I don't want to use gcc and Studio 11 together. Is there some way to get Studio 11 to compile the standalone library by altering the makefile?

Thanks for any advice/explanation people can offer. I'm a newcomer to compiling code on UNIX.
