我在安装需要在centos 6.8上进行编译的nodejs库时遇到问题。看起来应该使用较新版本的gcc-c ++编译节点v4依赖项。 我按照许多帖子的建议安装了devtoolset v3，以便能够使用gcc-4.9。但它仍然失败，同样的错误消息表明我还在使用不支持c ++ 11的编译器。 我做了strace，看起来devtools没有提供libgcc安装过程期望找到它，所以它最终采取常规的，这是gcc-4.4
设置：
[vagrant@localhost sflow]$ cat /etc/centos-release
CentOS release 6.8 (Final)
[vagrant@localhost sflow]$ node -v
v4.4.7
[vagrant@localhost sflow]$ npm -v
2.15.8
没有devtoolset：
[vagrant@localhost sflow]$ g++ -v

所以，问题是 - 在使用devtoolset在centos6上使用gcc-4.9时我缺少什么？ 还是有另一种方法在centos6上节点v4和pcap2？
答案 0 :(得分：1)
需要兼容C ++ 11的编译器（例如gcc 4.8或更高版本）。在帖子末尾的node-gyp rebuild输出中，它仍然看起来像你的4.9.2安装没有被选中。您可以使用env CC=/path/to/gcc CXX=/path/to/g++ LINKXX=/path/to/g++ LINK=/path/to/gcc node-gyp rebuild设置显式路径到正确的gcc / g ++二进制文件。
