* gdb: properly pass the PATH when building gdb for the hostThomas Petazzoni2012-11-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | When building gdb for the host, we properly pass the PATH (through HOST_CONFIGURE_OPTS) during the configure step, but we forget to do so for the compilation step. The result of this is that when the Crosstool-NG backend is used, gawk is built and installed in $(HOST_DIR), as a dependency of the crosstool-ng package. Then, the host gdb configure script detects this gawk binary ($(HOST_DIR) is in the PATH), and assumes gawk is available. Unfortunately, during the compilation step, it fails to find the expected gawk binary, because $(HOST_DIR) is no longer in the PATH. This causes the following build failure: http://autobuild.buildroot.org/results/067d0c2ea01673ba98ec11de2426f1ab92dac800/build-end.log In order to fix this, we simply call the compilation step of gdb for the host with $(HOST_MAKE_ENV), as it should have been done from the beginning.

* xtensa: fix target gdb build and 64-bit host side gdbChris Zankel2012-11-212-0/+41
| | | | | | | | | | Fix build breakage, use the version of the ptrace header file in asm instead of sys. Also, fix GDB running on 64 bit hosts. GDB was using unsigned long for 32-bit registers, but unsigned long is 64 bit on 64-bit hosts. Signed-off-by: Chris Zankel <chris@zankel.net> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

| | | | | | | | | | | Except for architecture and processor names, buildroot uses capitalized configuration names, so change the macro names for xtensa to follow that standard.

* xtensa: support configurable processor configurationsChris Zankel2012-11-151-0/+4
| | | | | | | | | | | | | | | | | | | Xtensa is a configurable processor architecture, which allows to define additional instructions and registers. The required variant specific information for the toolchain is delivered in an 'overlay' file, which needs to be 'untarred' to the corresponding directories after the source is installed and patched. This patch provides support for binutils, gcc, and gdb with a very limited changes to the build scripts. These additions are only executed for the Xtensa architecture and have no effect on other architectures. [Thomas: rebased on top of the 'arch: improve definition of gcc mtune, mcpu, etc.' patch, and changed 'Target ABI' to 'Target Architecture Variant'].

* gdb: adjust behavior when thread debug is not availableThomas Petazzoni2012-11-031-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | When an external toolchain without thread debug is used, the gdb package can be selected, but no version can be choosen, since none match any of the requirements. This leads Buildroot to try to build gdb for the target without a version being defined, as in the following build log: http://autobuild.buildroot.org/results/84e8fd2df0cc22448052a572c2e9a6e03dd137eb/build-end.log To fix this, we adjust the dependencies of the BR2_PACKAGE_GDB option so that the package as a whole is not selectable when the required conditions are not met. Basically, we have the choice of: * Having a toolchain that supports thread debugging, which is needed for gdb >= 7.x * Having BR2_DEPRECATED enabled, which allows gdb 6.8 to be selected, which doesn't require thread debugging * Using bfin, since this architectures has a special old gdb version Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* Remove the Xtensa architectureThomas Petazzoni2012-09-201-6/+1
| | | | | | | | | | | | | | As stated in commit 555c2585bf28c3ef71f6d2dcdd983d17a19892af, the Xtensa architecture has been introduced in 2009 and never changed since its initial introduction. It requires some special handling that is a bit annoying, and despite our call to the initial developers, and the announcement of the deprecation of the architecture during the 2012.05, nothing has happened. Therefore, drop support for this architecture. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: me Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* gdb: fix target gdb build when host-gawk is built beforeThomas Petazzoni2012-05-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | When the crosstool-ng backend is used, host-gawk is built as a dependency of the crosstool-ng package, and therefore an host 'gawk' binary is installed in $(HOST_DIR). When the target gdb package is also selected, this unfortunately leads to a build failure, as reported on http://buildroot.humanoidz.org/results/f19c0499d08212d8b5100fa9434e1197092957db/build-end.log. The problem is that the ./configure of gdb detects gawk in the PATH, but at compile time, it fails to find gawk. This is due to the fact that the gdb compilation process is started without the correct path. This patch fixes this by passing $(TARGET_MAKE_ENV) in the environment of the gdb compilation process. A better fix would be to switch gdb to the AUTOTARGETS infrastructure in the future.

* debug: provide an option to copy the gdbserver to the targetThomas Petazzoni2012-03-151-0/+8
| | | | | | | | | | | | | | When an external toolchain is used, it is very likely that it contains a pre-built version of a gdbserver that has the same version as the cross-gdb included in the external toolchain. So, we now provide an option that allows to copy this pre-built gdbserver to the target. As the location of the gdbserver in the external toolchain is not standardized, we only support the CodeSourcery and Crosstool-NG layouts for the moment. Other locations can be added later.

* gdb: also force ELF support for gdbhostPeter Korsgaard2012-01-241-0/+2
| | | | | | | | | | | | | | | | Similar to how we do for target (ee39d53ce3ee (Fix GDB BFD test linking)). Gdb comes with an embedded copy of libiberty, but binutils also installs libiberty.a into HOST_DIR. The gdb configure script tries to link against this one rather than the gdb version when it checks for ELF support. This may fail if those versions are not compatible, leading to obscure error messages from gdb at runtime such as: I'm sorry, Dave, I can't do that. Symbol format `elf32-$ARCH' unknown. Fix it by forcing ELF support. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* gdb: fix kconfig dependency handling with !BR_TOOLCHAIN_BUILDROOTPeter Korsgaard2011-11-241-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer versions of GDB need pthread debugging support if threads are enabled, which is always the case for glibc but is a configure option for uClibc. We have solved this for internal toolchains by selecting the BR2_PTHREAD_DEBUG option from the GDB selection if needed, but as this option isn't available when ctng/external toolchains are used, mconf prints ugly warnings and the build may fail if an external uClibc toolchain without pthread debugging support is used. Fix it by introducing 2 more hidden config options: - BR2_TOOLCHAIN_HAS_THREADS_DEBUG - BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED The first tells us if the toolchain HAS pthreads debugging support, and is checked by check_uclibc_feature in helper.mk for external uClibc based toolchains. The second tells us if the toolchain is ABLE TO provide pthreads debugging support if threads are enabled, either because it's an internal toolchain where we can force enable it or an external glibc/eglibc toolchain or uClibc with the option enabled. Crosstool-ng forcibly enables this support, so those will always work. The preconfigured uClibc-based toolchains we have also all enable it. Finally, show a comment if this isn't the case so the (external toolchain) user knows why. This is placed outside the choice option, as menuconfig has a bug where it doesn't show choice selections which only contain comments. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* toolchain/gdb: fixup version stringsYann E. MORIN2011-10-055-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gdb tarballs have been re-released after a GPL compliance issue was found: http://sourceware.org/ml/gdb/2011-09/msg00030.html So all versions were re-packaged. In the process, an 'a' was appended to the version strings, and unlike the binutils people, the gdb folks are not inclined in providing legacy symlinks: http://sourceware.org/ml/gdb/2011-09/msg00036.html So, this patch fixes the issue by renaming version strings. It is to be noted that, although the versions got bumped to include an 'a' at the end, the directory contained in the tarball is still named after the version string without the 'a'. For example: - old version : 6.6 - new version : 6.6a - tarball name : gdb-6.6a.tar.bz2 - directory name : gdb-6.6/ In fact, it does not pose any problem for buildroot, as the extract process explicitly mkdirs the directory to extract into, *and* strips the first level of the tree extracted from the tarball.
