Hi:
I followed the README in src/nmath/standalone/
to make the use the command "make shared" to make the
libRmath.so file. I also add the directories containg
libRmath.so to LD_LIBRARY_PATH by using command
"export
D_LIBRARY_PATH=$LD_LIBRARY_PATH:$/home/zhliu/Backup/R-2.0.1/src/nmath/standalon
e
"
However, when I try to run the following codes by the
command "gcc test.c -lRmath" on Linux Fedora Core 2,
/***********************************************/
/* file name test.c */
#define MATHLIB_STANDALONE 1
#include <Rmath.h>
int
main()
{
/* something to force the library to be included */
qnorm(0.7, 0.0, 1.0, 0, 0);
return 0;
}
/**************************************************/
the compiler gives me the following error message. It
seems definitions of some R functions can not be found
in the libRmath.so file. Anyone has any idea about
this
problem? Thank you very much!

[Rd] include C functions from nmath in my own C functions

You are missing functions from the math library.
