Erro ao executar make para construir o Sage no Ubuntu 16.04

Question

Eu estou tentando compilar o Sage no Ubuntu 16.04. Eu baixei os binários e instalei um pacote. Eu corro "make" no meu diretório Sage e é isso que eu recebo:

The following package(s) may have failed to build (not necessarily during this run of 'make all'):

The build directory may contain configuration files and other potentially helpful information. WARNING: if you now run 'make' again, the build directory will, by default, be deleted. Set the environment variable SAGE_KEEP_BUILT_SPKGS to 'yes' to prevent this.

Makefile:16: recipe for target 'all' failed make: *** [all] Error 1

Seguindo a sugestão na mensagem de erro, alterei minhas variáveis ambientais da seguinte forma (adicionei a segunda linha):

~/Desktop/SageMath$ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games" export SAGE_KEEP_BUILT_SPKGS=yes

Em seguida, seguindo uma sugestão aqui Eu executei o seguinte:

sudo apt-get install libstdc++6

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt-get update

sudo apt-get upgrade

Quando executo "make", ainda recebo os seguintes erros:

> [sagelib-7.3]  [sagelib-7.3] real 0m4.203s [sagelib-7.3] user 0m3.516s

Alguém pode, por favor, avisar? Qualquer sugestão seria muito apreciada. Obrigado!

    

Answer 1

1. Verifique se sua libstdc ++ atual tem GLIBCXX_3.4.21 :

   strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX_3.4.21
   

2. Crie um link simbólico da seguinte forma:

   ln -sf /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.21 /home/davidk/Desktop/SageMath/local/lib/libstdc++.so.6
   

3. make
