This question was first posted wrongly on R-help. Apologize for the inconvenience.

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 to  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 at pollux $ make clean
laurent at 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

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.

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

I am running Solaris 5.8 as non-admin user, compiler is gcc 2.95.3. Please let me know if more specific information about the environment is required.

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

Best regards,
