Installation problems about step 1.3

[lu1and10]

it seems in the last cp -f lib/libfmm3d_dll.lib C:\lib/ command something is broken.
Could you check if there is lib/libfmm3d_dll.lib in your source directory and manually copy lib/libfmm3d_dll.lib to C:\lib works or not?

[Derek-art]

在最后一个命令中似乎有什么东西坏了。你能检查一下你的源目录中是否有并手动复制到作品中吗？cp -f lib/libfmm3d_dll.lib C:\lib/``lib/libfmm3d_dll.lib``lib/libfmm3d_dll.lib``C:\lib

thank you for your advice,I have sovled this problem by changing yo Ubuntu ,but I have another question when run'make python'

it might because of the PEP668, the following link discussed some solutions: https://stackoverflow.com/questions/75602063/pip-install-r-requirements-txt-is-failing-this-environment-is-externally-mana

Are you able to install numpy if you type python3 -m pip install numpy?
We are moving to the new python build process.
So after you use python virtual environment, instead of using make python, could you also try pip install . -v

I try to change to the virtual environment,but it mention that as follows:

How can I bulid wheel successully? I have numpy installed already,why can't find numpy.distutils?

As I mentioned, did you try 'pip install . -v' instead of 'make python'. I can't see what command you typed in your terminal.
I guess 'make python' is not working for python 3.12. How about 'pip install . -v'?

[Derek-art]

正如我所提到的，您是否尝试过“pip install .-v“而不是”make python“。我看不到您在终端中输入了什么命令。我想“make python”不适用于 python 3.12。'pip install .-v'？
I have tried。

[lu1and10]

I see you 'cd python', could you don't 'cd python', and just stay in FMM3D-1.0.4 folder and try pip install . -v

[lu1and10]

Also please update/download the new repo, there is some changes in the new repo. I think you are using the old repo. The latest change is last Thursday.

[Derek-art]

另外，请更新/下载新的存储库，新存储库中有一些变化。我认为您正在使用旧的存储库。最新的变化是上周四。

Thank you for your suggestion. I successfully installed fmm3dpy by running pip install . -v in the FMM3D directory. However, when I ran pytest in the same directory, I encountered an error that seems to be due to circular imports. Could you please advise on how to resolve this?
else，I encountered the following issue while trying to compile a C program in the FMM3D/C directory. When executing the corresponding .make file, it prompts me that the gfortran file cannot be found, but I have already added the corresponding environment variable. I am not sure what the cause of the error is.

[lu1and10]

It looks like pytest is not finding the right python which installed the fmm3dpy-1.0.4
After activating your virtual env, could you try which python and see if the python is the one in your myenv, if the python is under your myenv, then could you try python -m pip list to see if fmm3dpy-1.0.4 is installed. Then try python python/test/test_lfmm.py and python python/test/test_hfmm.py works or not(don't cd to python, just stay in the fmm3d directory and try python python/test/test_lfmm.py).

for c/fortran/c++ code, could you check is the gcc-13 is installed? if so could you edit all the makefiles your are using to use gcc-13/gfortran-13/g++-13, it seems the system finds libgfortran.so of gcc-13, gcc-9 maybe the old compiler on the system.

[Derek-art]

看起来没有找到安装 fmm3dpy-1.0.4 的正确 python 激活您的虚拟环境后，您能否尝试查看 python 是否是您的 myenv 中的那个，如果 python 在您的 myenv 下，那么您可以尝试查看是否安装了 fmm3dpy-1.0.4。然后尝试和工作与否（不要cd到python，只需留在fmm3d目录中并尝试）。pytest``which python``python -m pip list``python python/test/test_lfmm.py``python python/test/test_hfmm.py``python python/test/test_lfmm.py

对于 C/Fortran/C++ 代码，您能否检查是否安装了 GCC-13？如果是这样，您可以编辑用于使用 gcc-13/gfortran-13/g++-13 的所有 makefile，似乎系统找到了 gcc-13、gcc-9 可能是系统上的旧编译器。libgfortran.so

I check the latest version of ffmm3dpy library is only 1.0.0 ah, also, gcc-9 is specifically under me, because I see that under lfmm3d_example.make it is written as gcc-9, I don't know if my understanding is wrong or not?

[lu1and10]

you can manually change lfmm3d_example.make yourself to use gcc-13, it is not required to use gcc-9, it was a dev makefile to test.
in the image #56 (comment)
It shows 1.0.4 is installed for you myenv python, while you still see 1.0.0. I'm confused about your python environment.
could pip uninstall fmm3dpy for your root python env and virtual myenv? Then pip install . -v to make sure 1.0.4 is installed.

[Derek-art]

您可以手动更改lfmm3d_example.make 自己使用 GCC-13，不需要使用 GCC-9，这是一个要测试的开发 Makefile。在图像 #56 中（评论）它显示 1.0.4 已为您安装 myenv python，而您仍然看到 1.0.0。我对你的 python 环境感到困惑。可以为您的根 python env 和 virtual myenv 吗？然后确保安装了 1.0.4。pip uninstall fmm3dpy``pip install . -v


Thank you very much for your tireless answer, I have one more question, how should I understand about nd(number of density) in emfmm3d? Why can it be used as a parameter of E and a parameter of e_charge?
