I followed Compiling from source.

I run:

  tar xvf PCL-1.5.1-Source.tar.bz2
  cd PCL-1.5.1-Source && mkdir build && cd build
  cmake ..
  sudo make install

I got:

  Scanning dependencies of target test_gaussian
  [  5%] Building CXX object common/test/CMakeFiles/test_gaussian.dir/test_gaussian.cpp.o
  Linking CXX executable test_gaussian
  [  5%] Built target test_gaussian

  make[1]: *** [common/test/CMakeFiles/test_macros.dir/all] Error 2

How to solve it?

Thank you~

Those instructions build a stand-alone PCL library. Is that what you want? It must be done differently to run PCL with ROS.

I just try,because ROS PCL only can run some parts of PCL tutorials. I want to set up an environment can run all PCL tutorials. By the way, how to solve the question I post original. Thank you~

Closing as off-topic (this issue would be best raised on the pcl-users mailing list) since this question is unrelated to ROS and is a problem with compiling the standalone version of PCL.
