Subject: [Rd] include C functions from nmath in my own C functions
Message-ID: <20050811165213.56487.qmail@web53107.mail.yahoo.com>

 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!
