After 12 or 13 tries, I found a buildable configuration using newer versions than my old 1.12 setup (except for binutils -- had to go back a version on that one): CT_ARCH_ARM_EABI=y CT_BINUTILS_VERSION="2.20.1a" CT_CC_VERSION="4.6.3" CT_LIBC_VERSION="0.9.33.2" CT_GDB_VERSION="7.4.1" CT_GMP_VERSION="5.0.2" CT_MPFR_VERSION="3.1.0" CT_PPL_VERSION="0.11.2" CT_CLOOG_VERSION="0.15.11" CT_MPC_VERSION="0.9" CT_LIBC_SUPPORT_NPTL=y CT_THREADS_NPTL=y A few notes: * It's a bad idea to use relative paths for configuration values. Instead, anchor them to the top directory: CT_KERNEL_LINUX_CUSTOM_LOCATION="${CT_TOP_DIR}/../linux-2.6.33.7-custom.tar.bz2 CT_LIBC_UCLIBC_CONFIG_FILE="${CT_TOP_DIR}/../uClibc.config" [I think this is the second time I've had to learn that lesson.] * Older versions of PPL are incompatible with gcc. * Newer versions of binutils are incompatible with uClibc. * uClibc configuration: * Large file support is required -- I couldn't get a build to work without it. * SUSV4 legacy support is required by libstdc++ * No clue what caused the "missing pthread.h" failure or what fixed it. Don't know yet if the resulting toolchain will build a working kernel or root filesystem. -- For unsubscribe information see http://sourceware.org/lists.html#faq
