I was able to compilethe toolchain for ppc860, NPTL and gcc4.0.1-libc-2.3.5with the following patch to crosstool-0.38.It's basically the NPTL-patch rediffed against 0.38 with anadded patch for libiberty path issues in patches/gcc-4.0.1.In addition see the if-condition in line 864 of the patch, herei added configuration & build of libcpp.Beware: I haven't tested the toolchain yet!Best regards, Peterdiff -urN crosstool-0.38.orig/crosstool.sh crosstool-0.38/crosstool.sh--- crosstool-0.38.orig/crosstool.sh	2005-07-21 19:58:19.000000000 +0200+++ crosstool-0.38/crosstool.sh	2005-08-07 11:34:34.551302360 +0200@@ -70,23 +70,28 @@ test -z "$BUILD" && abort "bug: BUILD not set?!"  if test -z "${GLIBC_ADDON_OPTIONS}"; then-   echo "GLIBC_ADDON_OPTIONS not set, so guessing addons from GLIBCTHREADS_FILENAME and GLIBCCRYPT_FILENAME"-   # this is lame, need to fix this for nptl later?-   # (nptl is an addon, but it's shipped in the main tarball)+   echo "GLIBC_ADDON_OPTIONS not set"    GLIBC_ADDON_OPTIONS="="-   case "${GLIBCTHREADS_FILENAME}" in-     *linuxthreads*) GLIBC_ADDON_OPTIONS="${GLIBC_ADDON_OPTIONS}linuxthreads," ;;-   esac+   if test '!' -z ${GLIBC_ADDON_LINUXTHREADS}; then+       GLIBC_ADDON_OPTIONS="${GLIBC_ADDON_OPTIONS}linuxthreads,"+   elif test '!' -z ${GLIBC_ADDON_NPTL}; then+       GLIBC_ADDON_OPTIONS="${GLIBC_ADDON_OPTIONS}nptl,"+   fi    # crypt is only an addon for glibc-2.1.x    test -z "${GLIBCCRYPT_FILENAME}"   || GLIBC_ADDON_OPTIONS="${GLIBC_ADDON_OPTIONS}crypt," fi +if test '!' -z "${GLIBC_ADDON_NPTL}"; then+    GLIBC_EXTRA_CONFIG="--with-tls --with-__thread ${GLIBC_EXTRA_CONFIG}"+    GLIBC_MIN_KERNEL=2.6.4+else+    GLIBC_EXTRA_CONFIG="--without-tls --without-__thread ${GLIBC_EXTRA_CONFIG}"+    GLIBC_MIN_KERNEL=2.4.3+fi+ # One is forbidden test -z "${LD_LIBRARY_PATH}" || abort  "glibc refuses to build if LD_LIBRARY_PATH is set.
