DNS resolv problem with glibc

2009-09-15T06:50:12Z

Fix problem with dns resolv, by copying the libnss_dns.so to the rootfs. Using glibc from external toolchain, name resolving does not work, unless libnss_dns.so is available on the target. Signed-off-by: Anders Darander Signed-off-by: Peter Korsgaard

Fix PROGRAM_INVOCATION handling with external toolchains

2009-07-31T09:40:34Z

BR2_UCLIBC_PROGRAM_INVOCATION is a toolchain configuration option, like BR2_INET_IPV6, BR2_INET_RPC, on which some packages depend. Therefore, it should be handled like BR2_INET_IPV6 and BR2_INET_RPC in order to work properly with external toolchains. Since we move it out of toolchain/uClibc/Config.in into toolchain/Config.in.2, we rename the option to BR2_PROGRAM_INVOCATION (since BR2_INET_RPC and others don't have UCLIBC in their name).

external toolchain: check cross-compiler existence

2009-07-17T06:53:55Z

As a minimal test to the external toolchain, check that $(TARGET_CC) is actually an existing executable file. That way, if the user misconfigures the toolchain path and/or prefix, a meaningful error message will be shown. Signed-off-by: Thomas Petazzoni

external toolchain: respect $(Q)

2009-07-17T06:48:35Z

Use $(Q) in external toolchain support so that the user can get the full output by passing V=1 to make, and still get a nice and clean output by default. Signed-off-by: Thomas Petazzoni

external toolchain: copy the C++ standard library if needed

2009-07-17T06:46:51Z

Obey the BR2_INSTALL_LIBSTDCPP configuration option to copy the C++ standard library to the target. Suggested by Lionel Landwerlin . Signed-off-by: Thomas Petazzoni

external toolchain: do not copy useless symbolic links

2009-07-17T06:46:43Z

Do not copy .so symbolic links to target when not needed. Only copy .so.X symbolic links and the library itself. Signed-off-by: Thomas Petazzoni

external toolchain: more documentation about the principles

external toolchain: use LANG=C when calling gcc -v

2009-07-16T22:10:46Z

Lionel Landwerlin reported that using the external toolchain support when LANG=fr_FR.UTF-8 doesn't work, since the messages printed by gcc -v are translated in another language, defeating the grep ^Configured test. Therefore, as per Lionel suggestion, we force LANG=C when calling $(TARGET_CC) -v. Signed-off-by: Thomas Petazzoni

external-toolchain: better documentation, cleanup, sysroot check

2009-07-16T22:10:33Z

* Introduce documentation for each function of ext-tool.mk, and document all parameters of the functions. * Pass SYSROOT_DIR as argument to all functions that require it, instead of computing it manually everywhere * Use $(shell) instead of backquotes * Check that the SYSROOT_DIR variable is not empty, which means that the external toolchain doesn't support --sysroot. In that case, bail out with a nice error message. Signed-off-by: Thomas Petazzoni

external toolchain: fix libraries copy and add ARM ABI check

2009-07-16T19:45:00Z

Instead of hardcoding the C library versions, just copy the version available in $SYSROOT_DIR/lib. Add a check on the ARM ABI configured in Buildroot with regard to the ABI of the external toolchain provided. Signed-off-by: Thomas Petazzoni
