The new prereq check is completely implemented in
POSIX shell in scripts/prereq.sh.
It combines the old features from Makefile, scan-tools.sh,
scan-pkgs.sh, reloc.sh and some wrappers for tools.
The big benefit is to have all portability stuff in one place.
Furthermore we can compile GNU make and bash on the fly, for
systems lacking the required tools.
All changes on the host are detected on the fly, no make
prereq required anymore.
The build process is separated in following three phases:
1. small wrapper Makefile is used for BSD make or GNU make
2. prereq.sh is called, doing all checking, calling Makefile.adk
3. old logic in Makefile.adk or mk/build.mk is used
Tested successfully on Linux, MacOS X, Cygwin, FreeBSD, OpenBSD
and NetBSD.
An old depmaker bug was fixed, only optional host tools are compiled.
For example, even when a host provides xz, a local xz was compiled
in the past, because other packages had a build dependency on it.

OpenADK can now build bare-metal toolchains.
Tested for ARM/MIPS. No runtime testing, yet.
|
|
Buildroot uses the two-stage mechanism since a while.
This reduces the build time a lot. Instead of three stages,
we just use the two-stage build. The benefit is that
the C library do not need to be rebuild and one gcc compile
is obsolete. Tested with embedded-test.sh.
There is one unresolved problem, tile toolchain
building is broken.

- Sync with Kernel upstream Kconfig
- use new feature visible
- add a patch for select on choices
https://lkml.org/lkml/2011/2/17/379
- rename ADK_LINUX -> ADK_TARGET_ARCH
- remove package collection feature
- add appliance feature to define a appliance
more complete

This helps to find any regressions made in uClibc-ng.
|
|
to avoid namespace collisions in some packages, rename TOPDIR.
Sorry you need to make cleandir && make prereq && make
|

establish an extra dir for toolchain. Better for preparing toolchain
for other projetcs without host tools only used by openadk.
Use /usr prefix. No symlink workarounds needed anymore.

know why this is required. the names are not unique between arch with different abi

* remove TCFLAGS/TLDFLAGS/TCPPFLAGS and only use
TARGET_CFLAGS/TARGET_LDFLAGS/TARGET_CPPFLAGS, ...
* activate GCC_HONOUR_COPTS and fix all packages to
honour CFLAGS
* use CC_FOR_BUILD, CFLAGS_FOR_BUILD, ... for all
build compilation, remove HOST* variants
* introduce KERNEL_MODULE_FLAGS for external kernel
modules
* mark rpm package as broken, mark syslinux for native builds
only, mark libhugetlb for eglibc/glibc only usage

- just use on sysroot directory for toolchain.
- add missing patches from previos commit. (rpath/cflags cleanup)
|
|
correct the wrong path and remove the correct files on clean.
Finetune more directory creation rules.
|
|
- gdb compilation can be disabled
- gcc languages (c++/java) can be enabled/disabled
- gcc stack smashing protection can be enabled/disabled
|
|
Make configuration of new targets cheap.
Just add a new file in target/arch/sys-enabled/foo.
See other files for syntax. While doing runtime tests
with the new infrastructure I've updated a lot of other
stuff:
- gcc 4.5.2
- uClibc 0.9.32-rc1 (NPTL)
- strongswan, php, miredo, parted, util-linux-ng, e2fsprogs
I promise, this is the last big fat commit this year ;)

all three libraries tested with qemu-x86

- $id$ substitution is not apropriate for git scm
