Hi All, I have already used gcc to creat a library, for example, it is called "test.a", which includes many c objects. How to link my main "a.c" function to this library when I used Rcmd SHLIB to complier my main c program? I tried "Rcmd SHLIB a.c test.a". It does not work this way. Does anyone have idea about this?

Hi Dr Ripley, Thank you for your email! Since I am a beginner on R, Could you tell me a little more, if you have time? First, where I can find makevar.win? I only saw "makefile" in my PC. Second, how to set PKG_LIBS in that file? I have read manaul agian, if I did something in this file, I can use -l or -L flags to pass linker, am I right? By the way, I have read your splus book, there you mentioned gnu complier. I can use gcc, dllwrap tool. Can I do this way? Now I am trying to firgure those out. I have some own package ( .a file), and I want to use them when I use .C function.

Can I do this way?Yes, but gcc -shared -o foo.so *,o test.a is better.> Now I am trying to firgure those out.
