2009-01-30Extend External Toolchain options (match buildroot built toolchain): Daniel Laird
Have added options that mean you can set the same BR2_XXXX variables for external toolchain and internal (buildroot built) toolchain. This means the same set of packages can be built now me as for you..... Signed-off-by: Daniel Laird <daniel.j.laird@nxp.com>
2009-01-18The liboil Makefile will use "-mcpu=vfp" when building for ARM.Ulf Samuelsson
The VFP is only available for a few ARM CPUs at the moment, so this breaks the liboil build. A patch is available upstream which only enables "-mfpu=vfp" if "--enable-vfp" is given to "configure". Autotools needs to be run for liboil for this to take effect. A new configuration BR2_VFP_FLOAT is added to allow enabling vfp. If this is "yes", then "-mfpu=vfp" is added to CFLAGS.
2008-12-15toolchain: use same gdb Config.in for internal/external toolchainsPeter Korsgaard
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).
2008-11-03External toolchain support improvementsPeter Korsgaard
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.

2008-07-17Kconfig: remove 'default n'Peter Korsgaard
'default n' is the default, so there's no need to say it explicitly.

2008-06-13toolchain: also setup kernel headers when ext toolchain is usedPeter Korsgaard
Provide kernel headers when ext toolchain is used, so we can compile packages which need them.
