s-function #77

Open rcone11 opened 4 months ago

rcone11 commented 4 months ago

I am trying to install block factory for the first time. I want to run the example in the blockfactory folder first. When I tried to run it in Simulink, I got an error saying it couldn’t find blockfactory. I also tried to mex blockfactory.cpp, but I couldn’t compile it successfully. I want to know if I missed any steps. What should I do to make Simulink find blockfactory?

traversaro commented 4 months ago

Please report the exact error, thanks.

I tried to mex blockfactory.cpp in matlab and got the error message: /usr/bin/ld: /tmp/mex_35266495627694_401685/BlockFactory.o: in function catchLogMessages(bool, SimStruct_tag*)': BlockFactory.cpp:(.text+0x123a): undefined reference to blockfactory::core::Log::getSingleton()’ /usr/bin/ld: BlockFactory.cpp:(.text+0x124c): undefined reference to `blockfactory::core::Log::getWarningsabi:cxx11 const’, this is just a small part of the error report.what should I do?thank you

请报告确切的错误，谢谢。

I opened the model in the example in simulink, and after running it, I encountered the following error: Error in S-function ‘Model/w// mask’: S-Function ‘BlockFactory’ does not exist Component: Simulink | Category: Model error Error in S-function ‘Model/w//o mask’: S-Function ‘BlockFactory’ does not exist Component: Simulink | Category: Model error. I have been trying to solve this problem, and I was thinking that if I successfully compile block factory.cpp in Matlab, this error would not exist. But I have been unsuccessful, maybe my approach is wrong?

The S-Function needs to be compiled via CMake, see https://robotology.github.io/blockfactory/mkdocs/install/#installation .

On this webpage, I have completed everything as instructed on Ubuntu 20.04.6, except for the last step regarding export BLOCKFACTORY_PLUGIN_PATH=/installfolder1/subfolder1/blockfactory:/installfolder2/subfolder2/blockfactory/:<...>. because I am not very clear on which files I need to export, can you please help me with this, sir?thank you

traversaro commented 4 months ago

That is an environment variable, see https://www.hostinger.com/tutorials/linux-environment-variables for a primer on that. You only need to set it once you have compiled your first blockfactory block, see https://robotology.github.io/blockfactory/mkdocs/create_new_library/ for an example on how to do that.

rcone11 commented 4 months ago

这是一个环境变量，有关这方面的入门知识，请参见 https://www.hostinger.com/tutorials/linux-environment-variables。您只需要在编译第一个 blockfactory 块后进行设置，有关如何执行此操作的示例，请参阅 https://robotology.github.io/blockfactory/mkdocs/create_new_library/。

So,sir do I not need to try mex blockfactory in Matlab? Just need to set export BLOCKFACTORY_PLUGIN_PATH=/installfolder1/subfolder1/blockfactory:/installfolder2/subfolder2/blockfactory/:<…> right, so that the example can run fine right? and on (https://robotology.github.io/blockfactory/mkdocs/create_new_library/) “You should now find in the ./build directories a new library file, which depending on your OS is: libExampleToolbox.so on Linux.” After I executed this, I did not find the libExampleToolbox.so, why is that? thank you

traversaro commented 4 months ago

Did you followed the instructions in the "Compiling instructions" in https://robotology.github.io/blockfactory/mkdocs/create_new_library/ ?

yes,I followed this command

Can you report the output of those commands?

It seems that you did not executed the command cmake --build ., unless I am missing something.

When I execute cmake build ., an error occurs: [ 42%] Linking CXX executable main /usr/bin/ld: /home/han/miniforge3/lib/libBlockFactorySimulinkCoder.so.0.8.5: undefined reference to `std::__throw_bad_array_new_length()@GLIBCXX_3.4.29’ collect2: error: ld returned 1 make[2]: [CMakeFiles/main.dir/build.make:88：main] Error 1 make[1]: [CMakeFiles/Makefile2:98：CMakeFiles/main.dir/all] Error 2 make: *** [Makefile:84：all] Error 2

Then I changed the command to cmake -Dcmake_CXX_STANDARD=14 --build ., the output is: Found BlockFactory 0.8.5 (Components: Core Simulink SimulinkCoder) – Found BlockFactory 0.8.5 (Components: Core Simulink SimulinkCoder) – Found BlockFactory 0.8.5 (Components: Core Simulink SimulinkCoder) – Found autogenerated sources for AutogenerationExample model. – Configuring done – Generating done – Build files have been written to: /home/han/blockfactory/example/build。It's wrong?

traversaro commented 4 months ago

Please always report the full errors you are encountering, otherwise it is really difficult to help you. : )

In the command cmake -Dcmake_CXX_STANDARD=14 --build . the --build part is ignored as you are passing a -D option, so basically you are not building anymore the example.

It seems that you are building inside a conda environement, can you please report the content of that environment with the output conda list ? My intuition is that you are trying to use libraries from that conda environment, but without installing the compilers for conda, but using the compilers from the underlying distribution, but that is not possible, as the libraries from conda require a newer C++ standard library, and hence the error you are seeing.

rcone11 commented 4 months ago

请始终报告您遇到的完整错误，否则真的很难帮助您。: )

在命令中，当您传递一个选项时，该部分将被忽略，因此基本上您不再构建示例。cmake -Dcmake_CXX_STANDARD=14 --build .``--build``-D

您似乎正在 conda 环境中构建，您能否通过输出报告该环境的内容？我的直觉是，您正在尝试使用来自该 conda 环境的库，但没有安装 conda 的编译器，而是使用底层发行版中的编译器，但这是不可能的，因为 conda 的库需要更新的 C++ 标准库，因此您看到的错误。conda list

My theory is correct, there is no compilers package. Either you deactivate the conda environment when you build blockfactory and all related packages, or you also install in the environment the packages required for C++ development, i.e. :

conda install cmake pkg-config make ninja compilers

If you do this, remember to delete the build folder before attempting again to compile, as the path of the C++ compiler is cached inside the build (in particular inside the CMakeCache.txt file).

I am sorry to bother you again. When my terminal was executing cmake --build . --target install, an error occurred in this last step:

It seems that you already installed blockfactory in your conda environment, so I guess you do not need to re-compile it from source. I guess you just need to compile the example block.

Just now I deleted the blockfactory folder in the computer and followed the instructions step by step, then this error occurred. Does this mean that this error can be ignored?

I'm sorry, I didn't make myself clear. The error I mentioned were those in my previous reply.

The error in https://github.com/robotology/blockfactory/issues/77#issuecomment-2082452979 mention the folder /home/han/blockfactory/build/, so I am not sure what you mean with "I deleted the blockfactory folder", as the error refer to the /home/han/blockfactory folder. Anyhow, as I stated before if you already installed blockfactory via conda, you do not need to install it again from source (i.e. following the steps in https://robotology.github.io/blockfactory/mkdocs/install/).

OK,Thank you for your sincere answer and the great help you have given me.
