* Drop /boot/common header paths
I don't think pre-pm haiku will build anyway
without using an older buildtools.
* Add secondary arch os header directories.
Anything secondary arch that provides os
headers will break without the proper search
paths in gcc.
* Fixes secondary packages that depend on the
OpenGL kit
Looks like it wasn't enough yet after the PM merge.
However we still have an issue with a silently failed Link action
which actually is smaller than the max line size...
Due to the use of STARTFILE_PREFIX_SPEC the path containing the
libraries gcc provides (libstdc++ and friends) was missing. So
revert to the previously used STANDARD_STARTFILE_PREFIX_{1,2},
MD_STARTFILE_PREFIX method.
* Rename to --with-hybrid-secondary and require as parameter the name of
the secondary packaging architecture. The value is used for
constructing the respective default header and library search paths.
* Add /boot/system/develop/headers/<arch> to header search paths.
* The build host's math library is needed, not the host's. Makes a
difference when build host != host, e.g. when cross-compiling a native
Haiku compiler on Linux.
* Rename the variable math_library -> build_math_library for clarity.
This is already done on x86 using the --enable-frame-pointer option
to GCC's configure script, but that option only works for 32-bit x86.
Added an option to haiku64.h that forces it off by default for 64-bit.
For its input files jam uses a buffer of 512 chars for fgets(). Lines
would therefore be split silently after that length, which could lead to
"interesting" issues. Now we fail to prevent the situation from going
unnoticed.
When reading the cache file failed we have to assume it is corrupt and
we should use any entries read from it. So now we remove the ones we
read again.
Checking for $(SYSTEM_HEADER_DIR)/limits.h doesn't work when
cross-compiling a native compiler, since that refers to the location of
the header on the target platform.
* add new configure-option '--enable-hybrid-secondary'
* pick alternative include- and library-paths, if in hybrid-secondary
mode
* switch to 'STARTFILE_PREFIX_SPEC', as that allows more obvious
specification of the search order
* unify INCLUDE_DEFAULTS for native and cross compiler, as we now
configure a sysroot and gcc will prepend the sysroot folder when
needed
* update flags in INCLUDE_DEFAULTS according to "documentation" in
cppdefaults.h
* configure.ac (mpfr-dir): When using in-tree MPFR sources
allow for the fact that from release v3.1.0 of MPFR the source
files were moved into a src sub-directory.
* configure: Regenerate.
* For /boot/common[/non-packaged] the standard include paths should be
develop/headers/ as well instead of include/.
* Build the standard library search paths (the system and common ones)
into the compiler as well. This makes setting the BELIBRARIES
environment variable superfluous.
* The obsolete search paths (/boot/common[/non-packaged]/include/ and
/boot/common/lib/ respectively) are still built in as well. They will
be removed after a grace period, when all packages have been adjusted
accordingly.
