 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!
