static-libraries - 没有可用的包 glibc-static

Question

我试图在编译 C++ 程序时静态链接库。
g++ (GCC) 4.8.5 20150623(红帽 4.8.5-4)

$ g++ -std=c++11 -I/home/jerry/Desktop/tiny-dnn -m32 -pthread -static train.cpp -o train
/usr/bin/ld: cannot find -lstdc++
/usr/bin/ld: cannot find -lm
/usr/bin/ld: cannot find -lpthread
/usr/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status

我找到了这个帖子
( /usr/bin/ld: cannot find -lc while compiling with makefile ) 表示要安装 glibc-static。

bash-4.2# sudo yum install glibc-static

如何安装 glibc-static？请帮忙。

谢谢。

Answer 1

glibc-static仅在可选 channel 中可用。可选 channel 中的 RPM 包是官方不支持的，这就是默认情况下不启用这些 channel 的原因。

启用可选 channel 的确切命令取决于产品变体。就像是

subscription-manager repos --enable=rhel-7-server-optional-rpms

可以工作，但细节取决于您的环境(此时它更像是系统管理员而不是编程问题)。

注: Red Hat 不支持静态链接的原因有很多。你真的应该避免它。
