thanks for all the help. i've tried everyone's suggestions, to no

Not *my* suggestion, though. Mine was to use the Makefile, which has
Rtest: Rtest.o embeddedRCall.o
$(R_CMD_LINK) -o $@ Rtest.o embeddedRCall.o $(LIBR)
and just needs the correction I mentioned.

Rtest.o is just an object file, and the second call to gcc is really a call
to ld and creates Rtest.so, a shared library. Neither is executable.
Probably you want to compile Rtest.c into an executable; it does have the
"main" function after all. Perhaps
gcc -L/usr/local/lib -o Rtest Rtest.o -L/usr/lib/R/bin -lR
would work.
that didn't work:
$ gcc -L/usr/local/lib -o Rtest Rtest.o -L/usr/lib/R/bin -lR
Rtest.o(.text+0x2f): In function `main':
: undefined reference to `eval_R_command'
collect2: ld returned 1 exit status

You can use the Makefile in that tests/Embedding/ directory
to build the Rtest application for you.
$ cd R-1.9.0/tests/Embedding/
$ ./configure
-/bin/bash: ./configure: No such file or directory
$ make
make: *** No targets specified and no makefile found. Stop.
$ aclocal
aclocal-1.9: `configure.ac' or `configure.in' is required
$ automake
automake-1.9: `configure.ac' or `configure.in' is required
$ autoconf
autoconf-2.59: no input file
do i have to write my own configure script?

Did none of you notice the Makefile in that directory?
Should be -L`R RHOME`/lib for R>=2.0.0 (and that Makefile needs
updating).
From ONEWS
o The dynamic libraries libR and libRlapack are now installed
in
R_HOME/lib rather than R_HOME/bin.
You may also need to set LD_LIBRARY_PATH: I do to include
/usr/local/lib.
$ gcc -L`R RHOME`/lib -o Rtest Rtest.o -L/usr/lib/R/bin/ -lR
Rtest.o(.text+0x2f): In function `main':

it looks like someone's going to have to spell it out for me.
