Error when loading module using linear algebra Eigen library #101

Closed neuroking closed 8 years ago

neuroking commented 8 years ago

Hello,

I am getting the following error message when I try to load my module into rtxi: ../src/plugin.cpp:51:Plugin::load : failed to load LKF.so: /usr/local/lib/rtxi/LKF.so: undefined symbol: _ZTV3LKF

I do not get any errors compiling the module.

I am not sure what to do at this point.

Vivek

This means that you are not properly linking the Eigen library to your module;

  1. make sure your library is properly installed
  2. the library's location is either in your search path
  3. you are including the appropriate linker flag (i.e. -lEigen) in your plugin's makefile

Hi Yogi,

It is not necessary to install Eigen to use the library functions. That being said is it necessary to install it for use with Rtxi?

All the supporting library functions I need to run my module are in subfolder within the module folder.

This is the Makefile configuration:

PLUGIN_NAME = LKF

HEADERS = LKF.h

SOURCES = LKF.cpp

INC = -I/RTXI/NetoffModels/LKF/Eigen

LIB = -L/RTXI/NetoffModels/LKF/Eigen

Do not edit below this line

include $(shell rtxi_plugin_config --pkgdata-dir)/Makefile.plugin_compile
