libmkl 学习笔记

1.libkml下载地址为：

https://github.com/libkml/libkml/releases

这里下载1.3.0版本

2.编译与安装

mkdir build

cd build

cmake ..

make

make install

如果想生成动态库，需要将CMakeLists.txt中第20行

option(BUILD_SHARED_LIBS  "Build shared libs." ON)

改成

option(BUILD_SHARED_LIBS  "Build shared libs." OFF)

3.测试程序

新建一个test.cpp，代码如下：

// parsekml.cc
// This program parses a KML Placemark from a memory buffer and prints
// the value of the <name> element on standard output.

#include <iostream>
#include <string>
#include "kml/dom.h"  // The KML DOM header.

int main() {
  // Parse KML from a memory buffer.
  std::string errors;
  kmldom::ElementPtr element = kmldom::Parse(
    "<kml>"
      "<Placemark>"
        "<name>hi</name>"
        "<Point>"
          "<coordinates>1,2,3</coordinates>"
        "</Point>"
      "</Placemark>"
    "</kml>",
    &errors);

// Convert the type of the root element of the parse.
  const kmldom::KmlPtr kml = kmldom::AsKml(element);
  const kmldom::PlacemarkPtr placemark =
    kmldom::AsPlacemark(kml->get_feature());

// Access the value of the <name> element.
  std::cout << "The Placemark name is: " << placemark->get_name()
    << std::endl;
}

与test.cpp同目录，新建一个CMakeLists.txt，内容如下：

cmake_minimum_required (VERSION 3.0)

set(PROJECT_NAME  libkmltest)
project (${PROJECT_NAME})

set (CPACK_PACKAGE_NAME ${PROJECT_NAME})
set (CPACK_PACKAGE_DESCRIPTION_SUMMARY "")

# same as gcc -I
include_directories(
  "/usr/local/include/"
)

link_directories("/usr/local/lib/")

# used for output
set (PUBLIC_H
  #  ${PROJECT_ROOT_PATH}/3rd_party/ros/xmlrpcpp/include/XmlRpcValue.h
)

# sources for create target
set (SRCS
  test1.cpp

)

# compile
add_compile_options ($<$<BOOL:${HAVE_NO_UNNAMED_TYPE_TEMPLATE_ARGS}>:-Wno-unnamed-type-template-args>)
add_executable (${PROJECT_NAME}
  ${SRCS}
)

target_link_libraries(${PROJECT_NAME} kmlbase kmlconvenience kmldom kmlengine kmlregionator kmlxsd)

然后执行如下代码：

mkdir build

cd build

cmake ..

make

再执行程序就可以看到测试结果
