我需要在Debian打包过程中短路一些安全功能。我在这里解释原因，知道你的第一反应可能是“不要禁用安全功能”和“更新程序以使用新的gcc进行编译。”

我必须使用gcc-4.6来编译一些库（http://pj.freefaculty.org/Swarm），因为这是提供传统Objective-C API的gcc的最后一个版本。之后，gcc删除了传统的标题。因此，“升级你的gcc”是不可接受的，因为我们使用传统的Objective-C有一个非常大的代码库。

在Ubuntu 17.04中，gcc-4.6不再可用，但我发现我可以通过从Ubuntu“可靠”中提取旧版本来安装它。它运行正常。我可以编译程序并以旧式Wed Nov 08 20:08:06 EET 2017 WARN: Establishing SSL connection without server's identity verification is not recommended.

但是，在构建Debian软件包时遇到了问题。当我运行make install时，正如我通常做的那样构建一个包，我遇到了失败，因为Debian打包系统插入了在gcc-4.6中不合法的CFLAGS。特别是，命令行包括dpkg-buildpackage -rfakeroot和-Wdate-time，两者都与gcc-4.6不兼容。

这是config.log的一部分。

-fstack-protector-strong

我用包查看了debian目录，我看到那些标志没有手动插入那里。据我所知，它们伴随着configure:3878: checking whether the C compiler works configure:3900: gcc -g -O2 -fdebug-prefix-map=/home/pauljohn/LinuxDownloads/Debian/sources/amd64/swarm-Ubuntu17.04/swarm-2.4.1=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -Wl,-Bsymbolic-functions -Wl,-z,relro conftest.c >&5 cc1: error: unrecognized command line option '-Wdate-time' cc1: error: unrecognized command line option '-fstack-protector-strong 。

我正在尝试编译的这个库是一个旧程序。它是我们在大约15 - 20年前与Santa Fe Institute合作的工作。重写这个旧代码以使用新的Objective-C接口是不合理的，因此在gcc-4.6的限制范围内生活是很重要的。

到目前为止，我收到的最有用的建议是放弃Debian / Ubuntu架构并转移到基于RedHat的架构，更容易容忍旧的gcc。事实上，在RedHat 6上，gcc-4.6会比往常有所提升，而我仍然可以在RedHat 7上安装gcc-4.6，据我所知。但是，我宁愿不排除Ubuntu用户。

有关如何导航的任何其他想法将不胜感激。

答案 0 :(得分：1)

相关文档为man 1 dpkg-buildflags

您基本上有两个选择：

  1. 覆盖dpkg构建过程的特定构建功能 ，希望删除正确的标记

    export DEB_BUILD_OPTIONS="hardening=-stackprotectorstrong reproducible=-timeless"
dpkg-buildpackage -rfakeroot

  2. 从特定构建变量中删除特定的构建标记 

    export DEB_CPPFLAGS_STRIP="-Wdate-time"
export DEB_CFLAGS_STRIP="-fstack-protector-string"
export DEB_CXXFLAGS_STRIP="-fstack-protector-string"
dpkg-buildpackage -rfakeroot

    3. 您还可以通过配置文件使这两种方式持久化。
