我正在尝试为Net-Tools-1.60构建静态二进制文件,因此它们可以在任何系统上自行运行。我从SourceForge下载了净工具的来源,并应用了3个补丁。然后,我用make SHARED=0 CC='gcc -static'
成功编译。编译的二进制文件显示为"静态链接"和一些工作,但有些则获得了"分段故障"。主要是 ARP 和路由不起作用。我也尝试了LDFLAGS="--static" make -j 4
,但是由此产生的二进制文件仍显示"动态链接"。
这是在Ubuntu 16.04上使用4.4.0-64代内核。有什么想法如何工作?

更新因此,我刚刚在旧的Ubuntu 11.10 32位上构建了工具。由此产生的二进制文件在我的Ubuntu 16.04 64位上正常工作。我认为16.04中可能有一个错误。
编译的二进制文件显示为"静态链接"和一些工作,但有些则获得"分割故障"
这是预期结果(假设崩溃发生在系统以外的系统上发生)。
与普遍的信念相反, linux上的静态库比动态链接的便于便携。
您应该收到这样的链接时间警告:
warning: Using 'getgrnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
解释。
更新:
在构建程序的同一系统上,撞车事故不会被期望。此崩溃看起来像一个glibc错误。
最终结果是相同的:不要静态链接;没有好的会出来。
