The CentOS bug tracker is open for suggestions from all
The RHEL buildsystem flags used are not published
systematically by Red Hat, in any venue that I am that I am
aware of. Obviously command line 'defines' and build
environment cause certain conditionals in a .spec file to be
triggered, one way or the other. Also the presence of -devel
type packages in a build chroot, not explicitly enumerated
through BuildRequires cause the auto-tools to add options
conditionally. Tool versions not publically released
sometimes are used to build packages [there were 'header
marks' from a gcc [and implied toolchain], that was never
externally released by Red Hat in the early 6 series, as I
recall]. And so on. The complexity explodes combinatorially
... and so a SRPM rebuild effort [of which CentOS is one]
builds, and tests, sometimes with ldd, and sometimes in other
ways, to see that a 'close enough' reproduction of the
binaries issued by Red Hat, are achieved
Out of curiousity, _what_ build environment 'flags' do you
all, participating in this thread, refer to? -- the thread
does not enumerate them explicitly, and one cannot expect to
hit by 'indirect fire', a target not exposed
With best regards, this New Year's eve
