configure problem

Hello Sir, I get this following error when I try to build R.

make
gcc -I. -I../../src/include -I../../src/include -I/usr/local/include
-DHAVE_CONFIG_H   -g -O2 -c bakslv.c -o bakslv.o
In file included from ../../src/include/R_ext/Arith.h:27,
                 from ../../src/include/Rinternals.h:24,
                 from bakslv.c:31:
/usr/local/lib/gcc-lib/sparc-sun-solaris2.8/2.95.1/include/math.h:5: math.h: No
such file or directory

*** Error code 1
make: Fatal error: Command failed for target `bakslv.o'

Current working directory /usr/local/R-1.3.1/src
*** Error code 1
make: Fatal error: Command failed for target `R'

But I can see the file:


ls -l /usr/local/lib/gcc-lib/sparc-sun-solaris2.8/2.95.1/include/math.h
-rwxr--r--   1 bin      bin          206 Sep 22  1999
/usr/local/lib/gcc-lib/sparc-sun-solaris2.8/2.95.1/include/math.h


I can not figure what is wrong.

Thank you very much for your time.

What exactly did you set?  You want to be using FC=f77 and CC=cc when
configuring R. You definitely do not want CC=CC.

the following message.
checking whether f77 appends underscores... yes
checking whether f77 and cc agree on int and double... configure:
warning: f77 and cc disagree on int and double
configure: error: Maybe change CFLAGS or FFLAGS?

Look in the config.log to see more details.  This is also a test of calling
Fortran from a C main program.  So it will fail if Fortran cannot be mixed
with C (for example, if CC was set to a C++ compiler), or if
LD_LIBRARY_PATH needs to be set to find the Fortran libraries, ....

I am not entirely sure what `Forte 6.1' is, but think it is a marketing
name for what were SunPro WorkShop compilers.  If so f77 and cc on Solaris
7 are part of our regular tests.
