Hi,

I am working at a major financial institution and we would like to embed R in one of our front office application. The application is written in C/C++ so I started by trying to compile the examples in "tests/Embedding" of R 2.0.1.

I have modified "tests/Embedding/Makefile" according https://stat.ethz.ch/pipermail/r-help/2005-February/064341.html and set "LD_LIBRARY_PATH" using

export LD_LIBRARY_PATH="/home/laurent/R-clean/lib/R/lib"

But I get the following error messages during linking:



laurent@pollux $ make clean
laurent@pollux $ make
gcc -I. -I../../src/include -I/home/laurent/R-2.0.1/src/include -I/usr/local/include -DHAVE_CONFIG_H -g -O2 -c /home/laurent/R-2.0.1/tests/Embedding/Rtest.c -o Rtest.o gcc -I. -I../../src/include -I/home/laurent/R-2.0.1/src/include -I/usr/local/include -DHAVE_CONFIG_H -g -O2 -c /home/laurent/R-2.0.1/tests/Embedding/embeddedRCall.c -o embeddedRCall.o ../../bin/R CMD LINK gcc -o Rtest Rtest.o embeddedRCall.o -L/home/laurent/R-clean/lib -lR mkdir .libs
gcc -o Rtest Rtest.o embeddedRCall.o -L/home/laurent/R-clean/lib -lR -R/home/laurent/R-clean/lib/R/lib
Undefined                       first referenced

ld: fatal: Symbol referencing errors. No output written to Rtest collect2: ld returned 1 exit status
*** Error code 1
make: Fatal error: Command failed for target `Rtest'

I have installed R from source using the following commands. I am running on solaris 8xx


laurent@pollux $ cd /home/laurent/R-clean/
laurent@pollux $ /home/laurent/R-2.0.1/configure --enable-R-shlib --prefix=/home/laurent/R-clean
laurent@pollux $ make
laurent@pollux $ make install

-----------------------

Has anyone an idea where is the problem? I would be extremly grateful if someone could help us.

Best regards,

Laurent
