Please read the posting guide and 1) Use the appropriate list, R-devel, and 2) Tell us enough about your environment, for example which OS this is.

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 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 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 symbol in file MAIN__ /home/laurent/R-clean/lib/libR.so ld: fatal: Symbol referencing errors.
