如何覆盖dpkg-buildflags CFLAGS？ [英] How to override dpkg-buildflags CFLAGS?

问题描述

我有一个包：

$ apt-get source <pkg-name>

现在我正在尝试使用：

$ dpkg-buildpackage -uc -us -j8

在输出的开头，有：

dpkg-buildpackage: export CFLAGS from dpkg-buildflags (origin: vendor): -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security
dpkg-buildpackage: export CPPFLAGS from dpkg-buildflags (origin: vendor): -D_FORTIFY_SOURCE=2
dpkg-buildpackage: export CXXFLAGS from dpkg-buildflags (origin: vendor): -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security
dpkg-buildpackage: export FFLAGS from dpkg-buildflags (origin: vendor): -g -O2
dpkg-buildpackage: export LDFLAGS from dpkg-buildflags (origin: vendor): -Wl,-Bsymbolic-functions -Wl,-z,relro

我想覆盖这些CFLAGS（也是LDFLAGS）。我尝试导出CFLAGS envvar，与plain configure相同，无效。如何覆盖这些值？

I would like to override these CFLAGS (also, the LDFLAGS). I have tried exporting the CFLAGS envvar, the same way we do with plain configure, at no avail. How can I override these values?

推荐答案

您尝试重建的程序包，设置（读取：覆盖）* FLAGS与从 dpkg-buildflags 中检索到的强化特定标志。

the package you are trying to rebuild, sets (read: overrides) the *FLAGS with hardening-specifics flags retrieved from dpkg-buildflags.

如果您需要为了自己的目的覆盖这些标志，你应该告诉 dpkg-buildflags 提供你想要的标志，而不是（强化）默认值。
查看 man dpkg-buildflags ，您会发现有关环境变量的部分，尤其是。见 DEB_flag_SET 和 DEB_flag_APPEND

if you need to override those flags for your own purposes, you should tell dpkg-buildflags to provide the flags you want, rather than the (hardening) defaults. looking at man dpkg-buildflags, you find the section about environment variables, esp. see DEB_flag_SET and DEB_flag_APPEND

所以这应该做技巧（填写你自己的*标题）：

so this should do the trick (fill in your own *FLAGS):

$ DEB_CPPFLAGS_SET="-I/foo/bar/baz" DEB_CFLAGS_SET="-g -O6" DEB_LDFLAGS_SET="-L/fruzzel/frazzel/" dpkg-buildpackage -uc -us -j8 -rfakeroot
