python3 setup.py install报错

[R4v3nl0]

抱歉我可能又要来提问了…… 我在使用Ubuntu 20.04安装seal时，在执行python3 setup.py install或执行python3 setup.py build_ext -i后均产生报错error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

我尝试了很多办法也无法去解决这个问题……在issue中找到了类似的问题，不过他是clang并且那个issue并没有解决emmmm

不知道您是否找到了解决方案呢？虽然我觉得我自己去回退版本可能是一个好的选择……

按照指示cmake出example后能够正常运行……

Have you apt-get install python3-dev? it may caused by the dev environment or something else.

Have you apt-get install python3-dev? it may caused by the dev environment or something else.

I've done this in the beginning, so I can't figure out why.

[Huelse]

what about your python dev version? like python-3.9-dev, and is there any more error detail?

python3-dev version is 3.8.2-0ubuntu2 when I compile, there are only two errors:

1. src/wrapper.cpp:486:104: error: no match for call to ‘(const pybind11::detail::overload_cast_impl<seal::Ciphertext&>) (<unresolved overloaded function type>)’
   486 | rload_cast<Ciphertext &>(&Evaluator::transform_to_ntt_inplace))
     |                                                              ^

2. error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

I see, just comment out line 486 and rebuild, or rewrite this function by lambda, we will fix it later.

I tried your suggestion, but there were new mistakes:

src/wrapper.cpp: In function ‘void pybind11_init_seal(pybind11::module_&)’:
src/wrapper.cpp:409:107: error: no match for call to ‘(const pybind11::detail::overload_cast_impl<seal::Plaintext&>) (<unresolved overloaded function type>)’
  409 | load_cast<Plaintext &>(&Evaluator::mod_switch_to_next_inplace))
      |

src/wrapper.cpp:423:112: error: no match for call to ‘(const pybind11::detail::overload_cast_impl<seal::Plaintext&, std::array<long unsigned int, 4> >) (<unresolved overloaded function type>)’
  423 | Plaintext &, parms_id_type>(&Evaluator::mod_switch_to_inplace))
      |

the old problems still exist error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

It's working fine in my workspace, which is similar to yours. The problem is probably caused by the pybind11 module, attention to git submodule update --remote, it's optional. So I suggest delete the pybind11 folder and reinit it.
