关于yaml-cpp版本

[gbdpf]

您好, 我在编译app时, 出现以下问题: ../../libs_x86_64_14.04/libxpparam.so：对‘YAML::detail::node_data::convert_to_map(std::shared_ptr<YAML::detail::memory_holder>)’未定义的引用

应该我的yaml-cpp版本问题, 我试过0.6.2 0.6.0 0.5.3 0.5.0四个版本,好像都不好使....

[mingyux]

libxpparam.so was compiled with yaml-cpp-0.5.3. Please give it a try again and let us know if it is still not working.

[gbdpf]

Thx. I have installed yaml-cpp-0.5.3 on my device. Finally, I found your CMakeLists.txt file did not link the library of yaml-cpp. So I add the following sentence in CMakeLists, and It works:

 find_package(yaml-cpp)
    ...
 target_link_libraries(${PROJECT_NAME}
    ...
    ${YAML_CPP_LIBRARIES}

Anyway, It's not a big problem.

@dpfzju 你好，请问你编译的系统版本是Ubuntu14.04还是16.04，可以详细说一下你的编译过程吗，在我的机器上没有出现错误警告。

[gbdpf]

系统是14.04. 忘了说了, 我修改的是: _app/depthdemo/CMakeLists.txt

[bruceche11]

我的16.04也出现了上述问题，按照楼上的修改了后，还是不行

[HansomHu]

@bruceche11 你在进行cmake时是否有提示找到了yaml库？能否将log贴上来看看？

this is my screen capture of my install of yaml-cpp-0.5.3

Please make sure about the following things:

1. Install yaml to default path, i.e. all headers to /usr/local/include/yaml-cpp/ and libraries to /usr/local/lib/. You can reference to install.txt in yaml-cpp-0.5.3. We suggest that compile & install from source file.
2. Download the latest code which has already fixed this issue, and try again.
3. Please follow the steps we provided to compile and build the boteye_driver.

[bruceche11]

Hi, @HansomHu Thank u for your work! But still not work . This time is like this:

and this is my yaml-cpp:

[HansomHu]

Have you empty your build folder? Please clear the build folder and redo cmake .. & make. Actually, libyaml-cpp.so is a symbolic link to libyaml-cpp.so.0.5.3, please check.

[HansomHu]

@bruceche11 Do you have built the repo successfully? Please let us know, thanks.

@bruceche11 Do you have built the repo successfully? Please let us know, thanks.

Sorry , busy with other work. but still not working, still that question. I see that libxpparam.so was compiled with yaml-cpp-0.5.3, perhaps something is wrong with it.

我按这个步骤，还是不行！还是这个问题！！

yaml-cpp 0.7.0 添加下面的代码即可解决

YAML::BadConversion::~BadConversion()
{
}

void  YAML::detail::node_data::convert_to_map(const shared_memory_holder& pMemory)
{
}
