[R] Urgent:again question about nmath/standalone
Hello, all,
I have the same question as the last mail I sent. I have installed libRmath in
my system. But I still can not link Rmath through -lRmath. The whole process
is as follow.Is there anybody who is so kind to help me find out the problem?
I will appreciate very much.

I have installed libRmath inI'd still recommend the same I sent you last time, e.g. in. http://tolstoy.newcastle.edu.au/R/help/04/04/0719.html Try with a smaller example that does not add your code as e.g. the test file I sent. I find debugging 'upwards' starting from the simple-most possible, and verified, test case, and the adding (and verifiying) incrementally, to be the most bullet-proof method.

WHY is this urgent? The error message is '/usr/bin/ld: cannot find -lRmath' so you have not put libRmath somewhere ld can find it. That is not an R question, and we can't help you solve it, especially as you have not told us your OS. It does look as if you may not have permission to read the copies in /usr/lib, but you haven't told us whether your user account is the same as bcdesai, not the search path ld is using. Please ask your local OS support for help. On Thu, 22 Apr 2004 xt_wang at cs.concordia.ca wrote:> Hello, all, > > I have the same question as the last mail I sent.
