Hi,
I posted this on stackoverflow as well (
http://stackoverflow.com/questions/32979586/using-cmake-to-build-rinside-examples-segfault),
but this is perhaps a better venue.
I am trying to use RInside in an existing C++ project that uses cmake (on a
linux box). I don't understand cmake that well. I thought I'd get started
by getting an example RInside program to work with cmake. I tried 2 things:
1) Copy rinside_sample1.cpp from the RInside/examples/standard directory
along with its Makefile to a separate directory. Run make and then run the
executable. This works like a charm and produces the expected output.
2) Copy the same example along with the cmake folder in the
RInside/examples/standard directory to /home/thenoob/tmp/RInside/src_cmake.
Create a separate build directory /home/thenoob/tmp/RInside/build and run
cmake ../src_cmake/cmake . This runs without any error. Then run make. This
spits out a bunch of warnings, but builds the executable.

</code>
However, as soon as I run the executable, it throws a segmentation fault. I
should mention that my R_HOME variable is not set and my LD_LIBRARY_PATH
contains
/statdev/ext/r/current/lib64/R/lib:/statdev/ext/r/current/lib64/R/library/RInside/lib.
Any pointers would be great.
Thanks!
