Introduction
This is a machine learing library written in c++, which will be updated when I am not busy.
Armadillo install
This library depends on the popular linear algebra library called armadillo.
To install armalillo on ubuntu, you should install some other library first. Do as described follow:
sudo apt-get install liblapack-dev
sudo apt-get install libblas-dev
sudo apt-get install libboost-devThen install armadillo
sudo apt-get libarmadillo-dev using armadillo in CLion
when using armadillo in clion, it need to configure the cmakelists.txt, there are several ways to do this.
Method 1:
add contents marked by #<<<
cmake_minimum_required(VERSION 3.3)
project(ThirdProject)
find_package(Armadillo REQUIRED) # <<<
include_directories(${ARMADILLO_INCLUDE_DIRS}) # <<< it is optional if armadillo include folder is put in /usr/include.
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp)
add_executable(ThirdProject ${SOURCE_FILES})
target_link_libraries(ThirdProject ${ARMADILLO_LIBRARIES}) # <<<more details, see: https://intellij-support.jetbrains.com/hc/en-us/community/posts/205823019-Errors-compiling-code-with-armadillo
Method 2: note that libarmadillo.so.4.200.0 and libarmadillo.so.7.500.2 must specify the absolute path, otherwise it will not be found, not known why so far.
cmake_minimum_required(VERSION 3.8)
project(xxtest)
set(CMAKE_CXX_STANDARD 11)
link_libraries("libarmadillo.so")
link_libraries("libarmadillo.so.4")
link_libraries("/usr/lib/libarmadillo.so.4.200.0")
link_libraries("libarmadillo.so.7")
link_libraries("/usr/lib/libarmadillo.so.7.500.2")
set(SOURCE_FILES main.cpp)
add_executable(xxtest ${SOURCE_FILES})
