Platform support is determined by _OPSYS_SUPPORTS_CTF from mk/platform, the
user enables support by setting PKGSRC_USE_CTF=yes, and packages can
explicitly disable support with CTF_SUPPORTED=no or skip certain files with
CTF_FILES_SKIP.
The path to ctfconvert is configured via TOOLS_PLATFORM.ctfconvert.
If all of the requisite variables are enabled, a compiler-specific debug flag
is passed via the wrappers to ensure we have DWARF information to convert,
_INSTALL_UNSTRIPPED is explicitly defined to avoid binaries being stripped
prior to conversion, and the conversion is performed during the install stage.
It is recommended that users who enable the feature also set STRIP_DEBUG=yes
to reduce the final binary size once the conversion has been performed.
This has been used for the past year in Joyent SmartOS builds. FreeBSD is
marked as supported but is untested.
OS X has been upgraded and Xcode hasn't been -- try again without
specifying the version. This (1) works better and (2) gives a better
error message when it doesn't. From Markus Mayer in PR pkg/50317.
If not, set _OPSYS_SUPPORTS_SSP=no during bootstrap and in mk.conf.
Do SSP detection on "SunOS", and let mk/platform/SunOS.mk's default
"yes" be overridden in mk.conf.
No change to generated mk.conf on NetBSD 8 or CentOS 6. Fixes bootstrap
on Tribblix.
Third-party (i.e. non-pkgsrc) C toolchains (I am using chromebrew)
install to /usr/local, as that is where you can have write access.
With this, a bootstrap on ChromeOS finishes successfully.
It currently tackles two problems:
- gcc(1) hard-coding full paths in debugging information (with one
caveat at the moment)
- ar(1) hard-coding user IDs in archive headers
This allows packages built from the same tree and options to produce
identical results bit by bit. This option should be combined with ASLR
and PKGSRC_MKPIE to avoid predictable address offsets for attackers
attempting to exploit security vulnerabilities.
This is still disabled by default, and only supports NetBSD so far.
As discussed on tech-pkg@
The currently implementation of SSP checks simply look for a DT_NEEDED
dependency on libssp, and doesn't yet have a way to check for it being
enabled when it is done via libc.
This appears to be causing issues with pkgsrc GCC attempting to insert
builtins it does not have, because we don't build libssp. unbreaks icu build.
there may be more problems from this issue in the future, but netbsd-7 is
better tested now.
This is only performed if PKG_DEVELOPER and RELRO are in use.
After a suggestion during my talk at BSDCan 2017; thanks!
Also, submitted on tech-pkg@ for review mid-June.
As a next step, it seems this can be extended to libraries, just like the
check for SHLIBS does (from which this is inspired).
Only four platforms, all BSDs, need to resolve "ELF/a.out" into
either ELF or a.out. Calculate it directly in the platform file
and return the value in ${_OPSYS_SHLIB_TYPE} and export that value
in bsd.prefs.mk as ${SHLIB_TYPE}.
Instead of requiring the file(1) tool, we can expect the base
system of those BSDs to have /usr/bin/file, so make use of it
directly.
while ago, but since then any packages that included both curses and
terminfo ended up with conflicting BUILDLINK_TRANSFORM entries, leaving it
to include ordering to determine whether the builtin or pkgsrc curses was
used. This keeps them in sync, at least by default, though ideally we'd
ensure that at an infrastructure level.
to "auto", which will enable cwrappers if the _OPSYS_SUPPORTS_CWRAPPERS
platform variable is set to "yes".
Switch over to cwrappers by default for Darwin, Linux, and SunOS (except when
using the sunpro compiler).
It's going on 10 years since gcc 3.4 and gcc 4.1 were part of DragonFly.
DF Release 4.4 is the earliest with any kind of support and the earliest
possible GCC version is 4.7 there.
simplifies _OPSYS_SYSTEM_RPATH and _OPSYS_LIB_DIRS
permitting lots of stuff using LIBABISUFFIX to work now.
TODO: probably similar for the armv7 platforms as
the pattern '${MACHINE_ARCH}-${LOWER_OPSYS}-gnu${APPEND_ABI}'
seems like it should work for both.
