c++ - 使用 gcc 静态编译一些包时出现关于 libprocps.a 的错误

Question

# g++ -v

好吧，我正在尝试使用 gcc 静态编译我的代码:

g++ build/test.o -o build/test -std=c++11 -DCURVE_MNT4 -DNO_PROCPS -I ./src/ -static -lm -lff -lstdc++ -lgmpxx -lgmp -lprocps

如果你只是在没有“-static”标志的情况下运行相同的命令，那段代码工作得很好，但由于项目需要，我们必须静态编译这段代码，所以我们必须使用“-static”标志，这里是一些日志:

# g++ build/test.o -o build/test -std=c++11 -DCURVE_MNT4 -DNO_PROCPS -I ./src/ -static -lm -lsnark -lff -lstdc++ -lgmpxx -lgmp -lprocps

有什么想法吗？我希望有办法解决这个问题，“gcc”方式或“ar -r”方式或“libprocps.a”的替代方案对我来说很好，我只是想知道如何使用 flag 成功编译“-静态”，谢谢大家

重新编译 libprocps没有 systemd 支持 (--with-systemd=no) 摆脱了 systemd 依赖并允许@Will_Z 创建一个完全静态链接的二进制文件。
