Hi, I'm wookhyun. I wanted to use your public fdtd3d source code. However, The following problems have occurred: @@ %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I've tried a lot of ways, but it hasn't been solved. Your help is desperately required.

zer011b commented 5 years ago

Simple make command will try to build all targets, and unit-test-approximation is not supported in release mode, for example. So you should use make fdtd3d.

Please, share build commands, which you've used.

Oh, Thanks for your kind reply. 1. I started to type the command as bellow :

%%%%%%%%%%%%%%%%%%%%%%%%%%% mkdir Release cd Release cmake .. -DCMAKE_BUILD_TYPE=Release make %%%%%%%%%%%%%%%%%%%%%%%%%%%

As a result, I found that ans error occurred and The reason is release mode.

2. I have another question about Prerequisites. I typed the command as bellow :

%%%%%%%%%%%%%%%%%%%%%%%%%%% ./install-cmake.sh export PATH=pwd/Third-party/cmake/bin:$PATH %%%%%%%%%%%%%%%%%%%%%%%%%%%

Then, I got an error message like this :

%%%%%%%%%%%%%%%%%%%%%%%%%%%

3. Finally, I'd like to simulate 'sphere.txt' in "./Examples". How can i proceed and get results?

I'm so sorry to bother you so much. Since I'm a beginner of Github and Linux, i need your help. Thank you for reading my @issue. Have a good day ~ !

  1. Example is not correct in this sense, it is very general. You can configure many parameters with cmake to be specific for your needs, see https://github.com/zer011b/fdtd3d/blob/master/Docs/Build.md. Then, invoke:

    make fdtd3d

  2. You do not need to build cmake manually, if there are binaries shipped for your OS (see https://cmake.org/download/).

  3. Launch is described in https://github.com/zer011b/fdtd3d/blob/master/Docs/Launch.md. Basically, you'll need to invoke:

    ./Release/Source/fdtd3d --cmd-from-file ./Examples/sphere.txt

On how to get output, see https://github.com/zer011b/fdtd3d/blob/master/Docs/Input-Output.md.
