toolchain: rename external toolchain dir

2010-07-28T14:20:03Z

Rename the external toolchain directory. When new backends are here, it will be easier to sort them out if they are all prefixed the same way. Signed-off-by: Yann E. MORIN Signed-off-by: Peter Korsgaard

Simple glibc-based external toolchain support

2009-06-15T18:48:27Z

The current Buildroot works just well with sysrootable glibc toolchains, using the external toolchain feature. The only thing that needs to be customized is the set of libraries that must be compiled to the target. The following patch takes a simple approach to making it easier for users to use glibc toolchains. It just adds a uClibc/glibc choice in the external toolchain menu. Then, depending on that selection, the configuration system will choose a sane default value for the library files list. The other advantage of having a uClibc/glibc choice is that in the future, we'll be able to add checks verifying that the external toolchain configuration matches the features selected in Buildroot (in terms of IPv6, RPC, locales or large file support).

toolchain: use same gdb Config.in for internal/external toolchains

2008-12-15T15:28:48Z

We used to use different gdb configs for internal and external toolchains because mconf won't source the same file twice. This works, but is kind of sub optimal, as people forget to keep them in sync. Fix it to use the same file for both situations by shuffling around the config options a bit. Should work identical to before (except for the newer gdb versions available for ext).

External toolchain C++ cross-compiler fix

2008-11-03T10:37:27Z

External toolchain C++ cross-compiler fix package/Makefile.in resets CXX to "" in TARGET_CONFIGURE_OPTS if BR2_GCC_CROSS_CXX is not set to 'y'. However, when using an external toolchain, BR2_GCC_CROSS_CXX is not set even if the toolchain has a C++ cross-compiler. This patch adds a new BR2_GCC_CROSS_CXX option in the external toolchain configuration menu, so that just like BR2_INET_RPC, BR2_INET_IPV6 and the others, it can be set according to the external toolchain configuration.

External toolchain support improvements

2008-11-03T10:18:39Z

Improve external toolchain support * Do not put kernel-headers in the dependencies of BASE_TARGETS in the case where BR2_TOOLCHAIN_SOURCE is not y. The kernel headers are already supposed to be part of the external toolchain, so there's no need to download, extract and install them. * In the configuration system, don't display the kernel headers version selection list when an external toolchain is selected. This is implemented by moving the source "toolchain/kernel-headers/Config.in" inside the if BR2_TOOLCHAIN_SOURCE in toolchain/Config.in.2. * Change the description and help message of the BR2_LARGEFILE, BR2_INET_IPV6, BR2_INET_RPC, and BR2_SOFT_FLOAT option in toolchain/external-toolchain/Config.in. In the case of an external toolchain, the semantic of these options is not to enable large file support, IPV6 or RPC (since the toolchain is already compiled, it has been decided previously). Their semantic is to let Buildroot know about the characteristics of the external toolchain being used. As an improvement, we could guess these values automatically: - for BR2_LARGEFILE, look at the value of __UCLIBC_HAS_LFS__ in bits/uClibc_config.h in the libc headers directory. - for BR2_INET_RPC, look at the value of __UCLIBC_HAS_RPC__ in the same file - for BR2_INET_IPV6, look at the value of __UCLIBC_HAS_IPV6__ in the same file - for BR2_SOFT_FLOAT, look at the output of $(CC) -v 2>&1 | grep -- "--with-float=soft" But I'm not sure how this would be possible, since these values are used at configuration-time by other configuration options, not only at build time.

Kconfig: remove 'default n'

2008-07-17T20:01:44Z

'default n' is the default, so there's no need to say it explicitly.

toolchain: more sensible uclibc defaults for external toolchain

2008-06-16T12:22:45Z

- revert some bad checkins, fixup bad settings in atmel targets and move the gcc target abi back to a place where the other arch-specific settings live

2007-09-26T21:12:38Z

reinstate AVR32 toolchain

2007-09-26T05:36:11Z

- remove one invariant in toolchain type selection.
