build error

[feiyuxiaoThu]

Dear authors, I have several problems when reproducing your results using your code.

os system: ubuntu 20.04 cmake results okay:

-- The C compiler identification is GNU 11.1.0 -- The CXX compiler identification is GNU 7.5.0 -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working C compiler: /usr/bin/cc - skipped -- Detecting C compile features -- Detecting C compile features - done -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ - skipped -- Detecting CXX compile features -- Detecting CXX compile features - done -- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython2.7.so (found suitable version "2.7.17", minimum required is "2.7") /usr/include/python2.7 -- Configuring done -- Generating done

while the make command meets with errors:

cc1plus: fatal error: CMakeFiles/frenet.dir/src/Frenet_path.cpp.d: No such file or directory compilation terminated. CMakeFiles/frenet.dir/build.make:75: recipe for target 'CMakeFiles/frenet.dir/src/Frenet_path.cpp.o' failed make[2]: *** [CMakeFiles/frenet.dir/src/Frenet_path.cpp.o] Error 1 CMakeFiles/Makefile2:82: recipe for target 'CMakeFiles/frenet.dir/all' failed make[1]: *** [CMakeFiles/frenet.dir/all] Error 2 Makefile:90: recipe for target 'all' failed make: *** [all] Error 2

I use Ubuntu 20.04.4 LTS. I change 2.7 to 3.8 for python version in CMakeLists.txt. Your compiler shows ambiguous results. You can add CMAKE_BUILD_TYPE to "Debug" in CMakeLists.txt. The following shows mine:

-- The C compiler identification is GNU 10.3.0
-- The CXX compiler identification is GNU 9.4.0
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works

Your cmake .. command shows too few results. No result for OpenCV at least.

Thanks for your quick reply. My debug info for cmake goes as follows:

cmake .. -D CMAKE_BUILD_TYPE="Debug" -- The C compiler identification is GNU 11.1.0 -- The CXX compiler identification is GNU 7.5.0 -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working C compiler: /usr/bin/cc - skipped -- Detecting C compile features -- Detecting C compile features - done -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ - skipped -- Detecting CXX compile features -- Detecting CXX compile features - done -- Found OpenCV: /usr/local (found suitable version "3.4.16", minimum required is "3.3.1") -- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython2.7.so (found suitable version "2.7.17", minimum required is "2.7") /usr/include/python2.7 -- Configuring done -- Generating done -- Build files have been written to: /home/feiyuxiao/Documents/github/LatticePlannerWithFrenet/build

However, when I run make command:

cc1plus: fatal error: 3.d: No such file or directory compilation terminated. CMakeFiles/frenet.dir/build.make:75: recipe for target 'CMakeFiles/frenet.dir/src/Frenet_path.cpp.o' failed make[2]: *** [CMakeFiles/frenet.dir/src/Frenet_path.cpp.o] Error 1 CMakeFiles/Makefile2:82: recipe for target 'CMakeFiles/frenet.dir/all' failed make[1]: *** [CMakeFiles/frenet.dir/all] Error 2 Makefile:90: recipe for target 'all' failed make: *** [all] Error 2

It seems my cmake config is okay, while the code buiding process meets with some errors.

Have you solved the build error? Your cmake command shows that OpenCV and others have been found. However, 3.d no such file I can not understand that because the project has no this file. Or you can try build Frenet_path.cpp and cubic_spline.cpp to shared libraries and link two libraries to main.cpp.
