it sames I can not read ply file?

[HeXu1]

coding:
" std::string file_path="data/test.ply";
cilantro::PointCloud3f cloud(file_path);"

when I was building,the output is
"/usr/local/include/cilantro/utilities/ply_io.hpp:11: undefined reference to tinyply::PlyFile::PlyFile()' /usr/local/include/cilantro/utilities/ply_io.hpp:12: undefined reference to tinyply::PlyFile::parse_header(std::istream&)'
/usr/local/include/cilantro/utilities/ply_io.hpp:11: undefined reference to `tinyply::PlyFile::~PlyFile()'...."

And when I try to use the visualizer,the output is :
" undefined reference to cilantro::Visualizer::Visualizer(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' /home/cidi/learning_code/myLocalization1/src/jiqunLocalization.cc:569: undefined reference to cilantro::Visualizer::spinOnce()'
/home/cidi/learning_code/myLocalization1/src/jiqunLocalization.cc:563: undefined reference to cilantro::Visualizer::~Visualizer()' /home/cidi/learning_code/myLocalization1/src/jiqunLocalization.cc:563: undefined reference to cilantro::Visualizer::~Visualizer()' "

the Pangolin is builded fine.

I can running your demo fine ,but it does not work in my project~
hope for you answer,thanks.

Hi,

Apologies for the late reply. It seems you are not linking against the library. If you used the default CMake settings for building cilantro and also use CMake for your project, you could simply try a CMakeLists.txt that looks like:

cmake_minimum_required(VERSION 3.9)
project(my_project)

find_package(cilantro)

add_executable(test_app test_app.cpp)
target_link_libraries(test_app ${cilantro_LIBRARIES})

Let me know if you still run into issues!

oh ,it works.
thanks for your help.Wish everything goes well.
