install failed

hello, i install pconsc4 on Python3.6 and tensorflow=1.10.0, but there are some problems:
error: Command "gcc -pthread -B /opt/conda/compiler_compat -Wl,--sysroot=/ -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -DENABLE_PYTHON_MODULE -D__PYTHRAN__=3 -DPYTHRAN_BLAS_BLAS -I

how to solve it? Thanks.

Hello,

I am also getting this error when trying to install. Please advise!

I am also getting the same error when trying to install. How to solve it?

Hi,

There is a problem in pythran 0.9.6, but if you revert back to 0.9.5 it should work.

I suspect some library is missing. Can you please show the full error?

Sorry for bother , but actually the problem is caused by something else.Downgrading binutils can solve it.
I deleted the reply after realized what happened, but somehow it was still visible for you.

The requirements of this porject should be more specific, after I tried lots of method to fix the compiling error. I found the solution
all requirements: gcc5, pythran==0.9.5, keras=2.2.4, tensorflow=1.14.0. More importantly, beniget==0.2.1, gast=0.3.3.
After all that, I recommend users of pip add the new feature 'pip install package --use-feature=2020-resolver'.

[PuYuQian]

gcc version 7.5.0 and pytorch=1.6 can also success.
More importantly, beniget==0.2.1, gast=0.3.3

Recently, i have also encountered this problem and solved it, now i want to share some experience.

1. When gcc < 5 the pyGaussDCA will not be installed successfully. If hard to update gcc, here i recommend installing a virtual environment by using devtoolset.
2. When tensorflow >= 2 the pconsc may be installed successfully, but it can not be used in python file. So the version of tensorflow must < 2.
3. As for python2 or python3, here i use the python3.7 and install the pconsc4 successfully, but it may occur some problems because of the conflict with the version of keras, but it will be solved eazily. I also test the python2.7, but i can not install pconsc4 and PYG under this condition, so finally i choose the version 3.7 of python. For pytorch, choosing anyone version that fit your os and the version of python you installed is ok.
4. So i recomend the following requirements: gcc7.5, pythran==0.9.5, keras=2.2.4, tensorflow=1.14.0, python3.7, and pytorch 1.7.
   Thanks for reading, and hoping these tips will help you!

I failed by gcc-4.8, and gcc-5.1 works.
beniget-0.2 and gast-0.3.3 are also important.

gcc version 7.5.0 and pytorch=1.6 can also success. More importantly, beniget==0.2.1, gast=0.3.3

非常感谢~ 解决问题，成功安装！
