are handled. The idea now is to simply remove the paths in the values
of these variables, leaving behind only the basename plus any arguments,
e.g.:
CC= /usr/local/bin/gcc becomes CC= gcc
CPP= /usr/local/bin/gcc -E becomes CPP= gcc -E
The wrapper scripts are generated for every unique executable mentioned
by the toolchain variables, so for the example above, only a "gcc"
wrapper script is generated for ${CC} and ${CPP}. PKG_{CC,CPP,CXX,etc.}
are the paths to the executables wrapped by the wrapper scripts.
Note that it's now possible to set "CC" to something more than just the
path to the compiler, e.g.
CC= cc -ffast-math -funroll-loops -fomit-frame-pointer
and the full value of ${CC} will be passed through via CONFIGURE_ENV
and MAKE_ENV.
for it from compiler.mk.
Move the variable of the same name used by compiler/gcc.mk and
the gcc* buildlink3 files into private namespace (_USE_GCC_SHLIB).
PKGSRC_COMPILER requested it, assume that it's available, so that
compilation will (properly) fail if the hook program is somehow not
correctly installed.
6.0 on Mac OS X 10.3.5.
to use XL C, set PKGSRC_COMPILER=xlc in mk.conf. XLCBASE defaults to
/opt/ibmcmp/vacpp/6.0 (the default installation location on OS X),
this can be overridden in mk.conf too.
this is a work in progress - some simple packages can be built, but
there are still lots of issues that need to be worked through.
the non-buildlink-related code and moves it out of mk/buildlink3 into
mk/wrapper. The buildlink3 code is modified to simply hook its
transformations into the wrapper script framework.
The wrapper script framework has some new features:
* Support automatically passing "ABI" flags to the compiler and linker
depending on the value of ${ABI}. Currently supports the SunPro
compiler with ${ABI} == 64 and the MIPSPro compiler with ${ABI} as
any of 32, n32, o32, and 64.
* making UnixWare GCC accept -rpath options and silently converting
them into an appropriate LD_RUN_PATH
* Add cmd-sink-interix-gcc and cmd-sink-interix-ld that errors out
when it sees -fpic/-fPIC and -shared/-Bshareable, respectively
(requested by <tv>).
* Much improved debugging output. It's possible to output the wrapper
work log in-line with normal output by setting WRAPPER_LOG to
"stderr".
Important differences in behaviour from the old buildlink3 code include:
* Only move the -l options to the end of the command line, leaving the
-L options in-place.
* Extend the autodetection of the libtool mode to detect "compile" and
"uninstall".
* Fix problem noted in both PR pkg/24760 and PR pkg/25500, where
-L/usr/lib/* was being mangled improperly.
* Remove the top-level "buildlink" target; instead, make buildlinking
occur as part of the "wrapper" target.
* mangle and sub-mangle are only meant to transform directories in
-I, -L, and rpath options, so remove the lines in
buildlink3/gen-transform.sh that transformed bare directories.
* Add the ability for the libtool wrapper to be called just to unwrap
an existing libtool archive by running:
libtool --mode=unwrap -o libfoo.la
The old --fix-la syntax no longer works.

========
* Initial release of a new wrapper script framework that encapsulates
the non-buildlink-related code and moves it out of mk/buildlink3.
These features include:
* making MIPSpro accept GCC options
* making MIPSpro "ucode" accept GCC options
* making SunPro accept GCC options
* making "ld" accept -Wl,* options and silently removing the "-Wl,"
* (NEW) making UnixWare GCC accept -rpath options and silently
converting them into an appropriate LD_RUN_PATH
One major benefit of this is that the buildlink3 code is now much
tighter and easier to understand since it concerns itself solely
with buildlink-related details. I haven't yet optimized the wrapper
cache, so the new wrapper scripts may take slightly longer to execute
than the old buildlink3 wrapper scripts, but I'll be improving this
over time.
20040821
========
* Move the inclusion of $cmd_sink outside of the main loop in wrapper.sh
so that the $cmd_sink script can be used to globally scan and process
the arguments. Move the LD_RUN_PATH code to a cmd-sink-unixware-gcc
script. Garbage-collect the now unused export_vars-related code.
* Add cmd-sink-aix-xlc for AIX xlc that munges -Wl,-R* into an
appropriate -blibpath option.
* Add cmd-sink-interix-gcc and cmd-sink-interix-ld that errors out
when it sees -fpic/-fPIC and -shared/-Bshareable, respectively
(requested by <tv>).
* Move the code that converts full paths to shared libraries into the
"-Ldir -llib" equivalents from the buildlink3 code into wrapper/logic.
Remove the same from bsd.buildlink3.mk and gen-transform.sh.
* Move the code that checks for absolute rpaths from the buildlink3
code into wrapper/arg-source. Remove the same from bsd.buildlink3.mk
and gen-transform.sh.
* Only move the -l options to the end of the command line, leaving the
-L options in-place.
* Add more debugging code.
20040824
========
* Fix quoting problems after arguments are transformed. Remove the
hack that was inserted that magically made almost everything work
because we do it the right way now.
* Move the inclusion of $logic outside of the main loop in wrapper.sh
so that the $logic script doesn't have to worry about underflowing
the argument buffer.
* Encapsulate the loop in wrapper.sh that fills the argument buffer
entirely within the arg-source script.
* Move from the logic script into the arg-source script the
transformations that merge or split arguments.
* Fix bug where skipargs was effectively being ignored if it was more
than 1.
* Handle the whitespace in transformations in the logic script that
turn one library option into multiple library options, e.g.
"-lreadline" -> "-ledit -ltermcap".
* Allow you to specify an environment variable WRAPPER_SKIP_TRANSFORM
for whether you wish to skip the transformation step in the logic
script. This is intended for testing purposes.
* Added check_prog() and init_lib() functions to the shell code library
to make it more reusable outside of the wrapper framework.
* Allow the msg_log() function to output to "stdout" or "stderr". If
you want to have all of the logging appear on the screen, then you
can now set WRAPPER_LOG=stderr.
* Make some of the script components not overridable on a per-wrapper
basis.
* Add a gen-transform.sh script that generates transformation sedfiles.
The "transform" script is used to transform arguments, while the
"untransform" script is used to unwrap files. Move the no-rpath
logic from buildlink3/gen-transform.sh into wrapper/gen-transform.sh
since it's not buildlink3-specific.
* Check for a non-empty blibpath before adding the option in
cmd-sink-aix-xlc.
* Extend the autodetection of the libtool mode to detect "compile" and
"uninstall".
* Add a cmd-sink-libtool script that doesn't pass linker options to
libtool unless we're in "link" mode.
* Set _USE_RPATH to "yes" for UnixWare so that the wrappers will see the
rpath options and convert them to a LD_RUN_PATH definition.
* Add more debugging code.
20040826
========
* Rewrite buildlink3/gen-transform.sh to produce more precise sed commands.
Drop some unused commands from the mini-language, and add a few more
that are more restrictive in their scope.
* Fix problem where repeated options weren't properly handled by some
of sed commands. It's not enough that they're "global replace",
since some patterns match separator characters before and after each
option. We must repeat those patterns twice to catch all instances
correctly.
* Fix problem noted in both PR pkg/24760 and PR pkg/25500, where
-L/usr/lib/* was being mangled improperly.
* Remove the top-level "buildlink" target; instead, make buildlinking
occur as part of the "wrapper" target.
* Add more debugging code.
20040828
========
* Added a head_queue function to shell-lib that returns the head of the
named queue without popping it off the front of the queue.
* Strip consecutive, repeated library options from the command line when
we read it in the logic script.
* Be more careful about not underflowing the argument buffer.
20040906
========
* shell-lib was moved into pkgsrc/mk/scripts; correct references to that
file in the wrapper code.
* Use opt-sub instead of sub-mangle when protecting -I/usr/include/*
and -L/usr/lib/* from buildlink transformations. This avoids adding
lines that look like "-I-I..." in the transformation sedfiles.
* mangle and sub-mangle are only meant to transform directories in
-I, -L, and rpath options, so remove the lines in
buildlink3/gen-transform.sh that transformed bare directories.
* Fix bug in strip-slashdot where the "." wasn't backquoted and thus
matched all characters instead of only the "." character.
* Change the libtool wrapper to use a modified buildcmd script that
doesn't rearrange any of the arguments. This should fix spurious
problems where libtool doesn't understand how to parse the command
line when the -l options are moved to the end of the argument list.
* Fix bug in the logic script where the $cachearg and $cachedarg
weren't being properly set at all times, which caused the cache to
contain the wrong transformed argument.
20040907
========
* Support automatically passing "ABI" flags to the compiler and linker
depending on the value of ${ABI}. Currently supports the SunPro
compiler with ${ABI} == 64 and the MIPSPro compiler with ${ABI} as
any of 32, n32, o32, and 64.
* Move back the code that splits absolute paths to shared libraries
from arg-source back into logic. This allows us to correctly skip
splitting those paths based on the previous option. Also add a
sanity check that the library name in the split argument doesn't
contain a "/" since shell globs are not as precise as REs.
* Don't transform the path given after --dynamic-linker (used by GNU
ld for ELF linkage).
* Add the ability for the libtool wrapper to be called just to unwrap
an existing libtool archive by running:
libtool --mode=unwrap -o libfoo.la
20040914
========
* Add a loop in libtool-fix-la to ensure that all of the options listed
in the dependency_libs lines of *.lai files are processed. This fixes
a buildlink3 leakage bug.
* Merge the gen-transform.sh scripts between buildlink3 and wrapper and
place them all in wrapper. This makes sense since the commands simply
allow for many types of transformations, which buildlink3 takes
advantage of, but there is nothing inherently buildlink-ish about
those commands.
* Don't directly manipulate SUBST_SED.unwrap. Instead, create the
value of SUBST_SED.unwrap by combining several other variables
(currently just _UNWRAP_SED) to ensure that the correct ordering is
preserved.
* Correct some confusing debugging messages.
which are the full option names used to set rpath directives for the
linker and the compiler, respectively. In places were we are invoking
the linker, use "${LINKER_RPATH_FLAG} <path>", where the space is
inserted in case the flag is a word, e.g. -rpath. The default values
of *_RPATH_FLAG are set by the compiler/*.mk files, depending on the
compiler that you use. They may be overridden on a ${OPSYS}-specific
basis by setting _OPSYS_LINKER_RPATH_FLAG and _OPSYS_COMPILER_RPATH_FLAG,
respectively. Garbage-collect _OPSYS_RPATH_NAME and _COMPILER_LD_FLAG.
some packages (for example ntp4) have configure scripts that try to be
clever and insert their own if they don't find any. This would be wrong
on a system that relies on /etc/compiler.defaults to choose the correct
ABI.
(Not having this set caused various rpath related problems, as the compiler
was passed ' -rpath,/path' instead of '-Wl,-rpath,/path', leading to
a rpath of ",path", which of course wouldn't work.)
-traditional flag; you need to use "gcc -E" to get sane behavior.
Override sys.mk's definition of CPP in defs.Darwin.mk, and don't
re-override CPP in gcc.mk if ${OPSYS} == Darwin.
banner the use of "#include" over "#import" when including headers.
This generates a _huge_ number of warnings when building practically all
Objective-C code where it is convention to use "#import". Suppress
the warning if we're building Objective-C code using GCC by passing
-Wno-import to the compiler.

lists, then just assume that we need gcc3. The rest of the code in the
file assumes that we either need gcc2 or gcc3, so this provides a
fall-through, default value.
Package Makefiles may now directly include compiler.mk.
* Don't include compiler.mk within bsd.prefs.mk any longer. It was only
included for the purposes of defining CC_VERSION. Packages that want
to test the value of CC_VERSION should now first include
"../../mk/compiler.mk". Any GCC_REQD statements in package Makefiles
should be set before compiler.mk is included.
* Simpllfy pkgsrc/mk/compiler/*.mk files as a result of not needing to
be included indirectly by bsd.prefs.mk. We remove the special handling
associated with detecting whether the file was included from within
bsd.prefs.mk. These files are now much more straightforward to write
and understand.
* G/C the BSD_PREFS_MK stack mechanism as the only users (compiler/*)
no longer need it.
* Ensure that directories are prepended to the PATH only from within
bsd.pkg.mk.
compiler set. This will cause the libtool configuration found in several
packages to use the correct C++ compiler even though the package doesn't
use C++. This was causing bugs when CXXFLAGS contained flags not
understood by the system gcc-2.95.3.
