I tried various ways to build, always run into this error.

Hi, Pochung

Thanks so much for open the issue. Could you pull the latest version now and try is again, there are major changes done recently by me.... sorry for that.

How do you build the python extension?

I do something like make build cd build cmake .. make (which build the wrapper)

or python setup.py build_ext -i (but I think this is also cmake based?)

I figure out that you need to add/modify CMakeLists for the new functions you add recently. After some minor modification, I can build and load the wrapper OK.

I will write some comment about this later today pc

I haven't update the cmake part, so probably it will faild.... so right now I only tested via plain make. Maybe that's the issue. I will try to do cmake update later

1) make the library $make -Bj4 2) make the python wrapper $make pyobj

I've fix the cmake install error. It is missing the following new added files in CMakeLists.txt

1. utils/Complexmem_cpu.cpp (.hpp) ,utils/cuComplexmem_gpu.hpp (.cu)
2. linalg/ExpH.cpp
3. random/* Please see the latest push 52d5082be343b0304ac77dd9b1a8a4791dac6d4e

I think it is working :) I will port more examples soon.

Great! Thanks! I am closing the issue.

[pcchen]

我想建議一下使用 release

https://help.github.com/en/enterprise/2.16/user/github/administering-a-repository/creating-releases https://help.github.com/en/enterprise/2.16/user/github/administering-a-repository/creating-releases

把比較 stable 的特定 commit 先 tag 然後 release。這樣使用者可以只先專注在這些版本。

例外，請問你最近 Tensor （含）以下的東西還會有比較大的變動嗎？還是你只會改 Extension （含）以上的東西？

Thanks pc

Hi Pochung,

Thanks! I've create a v0.5.0 pre-release tag for the latest stable push.

For Tensor, 1) There should not be significant API change in the future (some argument order might change slightly in C++ side in order to make consistent with python binding.) But the whole design structure will not be change. 2) More cytnx.linalg functions will be added later and will be optimize (both CPU part and GPU part) at the internal level, so API won't change. 3) cytnx_extension is now in experiement stage, so it might be change a bit, but overall design should not change dramatically
