The gnuarm.com toolchain works fine but is very old. And although it is based on newlib, the tuple that we used to configure for was arm-elf-linux, which is bogus since we aren't building for Linux. This patch optimizes for the CodeSourcery G++ Lite 2010.09 ARM EABI toolchain instead, and for libosmocore installation it assumes that the new toolchain was unpacked next to the old one. Download it here: http://www.codesourcery.com/sgpp/lite/arm/portal/release1592 (The Linux Installer seems not to work reliably so I recommend the TAR.) Since CC is detected by configure when the host tuple points to a sane toolchain we shouldn't hard-code the gnuarm.com compiler. The patch autodetects arm-elf-gcc installed in PATH, and uses arm-elf as prefix if it is found. Otherwise, it defaults to arm-none-eabi. make CROSS_HOST=arm-xyzzy can be used to override on the command line. --- src/Makefile | 11 +++++++---- 1 files changed, 7 insertions(+), 4 deletions(-) diff --git a/src/Makefile b/src/Makefile index b3594c1..402f28a 100644 --- a/src/Makefile +++ b/src/Makefile @@ -1,10 +1,13 @@ # this is not really used as we don't do 'make install'.
