R help - Mar 2006 - library file for R's nmath routines

Hi,

I am wondering where the library file for R's nmath routines are?

Doing a search on libR gave me the following:
/usr/lib/libRKC16.so.1.2.0
/usr/lib/libRKC.so.1.2.0
/usr/lib/R/lib/libRlapack.so
/usr/lib/R/lib/libR.so
/usr/lib/libRKC.so.1
/usr/lib/libRKC16.so.1

None of these have the functions in nmath.

Any help? Many thanks and best wishes!

libR.so must have if this is a functional build of R.

But you have missed so much it is hard to help you.  You have not followed 
the posting guide and told us anything about your R installation.  If you 
installed from sources, you missed src/nmath/standalone/README.  If this 
were a RedHat RPM, you missed separate RPMs for libRmath.  And so on.

Thanks! I will not give my e-mail address (hence the real name and
affiliation), until the R-newsgroup moderators stop saving e-mail addresses to
the archive, for spiders to pick up easily.

Yes, I did not know how to get them, and I am sorry for not knowing, but part
of being a professor is to tell people how to go about learning.

Many thanks for all your help! I have downloaded the libRmath RPM but (as you
point out), it is not necessary. So, thank you again!!

Best wishes.

I guess that you intended to send this message to the list. :-)

  Why do you link against libm?

  Shouldn't it be
gcc test.c -I/usr/lib/R/include -L/usr/lib/R/lib -lRmath -lR
?
