Peter Stuge peter at stuge.seThe 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 of course bogus since we aren't building Linux applications. This patch optimizes for the CodeSourcery G++ Lite 2010.09 ARM EABI toolchain, and assumes that it was unpacked next to the old one. Download here: http://www.codesourcery.com/sgpp/lite/arm/portal/release1592 (I haven't gotten the Linux Installer to work, so I recommend the TAR.) And since CC is detected by configure when a valid host tuple is given and that toolchain is sane there's no need for us to hard-code the gnuarm.com compiler name in our Makefile. --- src/Makefile | 11 +++++++---- 1 files changed, 7 insertions(+), 4 deletions(-) diff --git a/src/Makefile b/src/Makefile index b3594c1..f2d935b 100644 --- a/src/Makefile +++ b/src/Makefile @@ -1,10 +1,13 @@ # this is not really used as we don't do 'make install'.
