# HG changeset patch # User "Yann E. MORIN" # Date 1238093254 0 # Node ID 5594b05bc2d82d34ee33b0ed1bf3dce76d7c3087 # Parent ca485f06bfa7798b9c37617ce0e4ae396ff1013b Add support for building toolchains with gcc-4.4 snapshots. Initial patch by Dmitry PLOTNIKOV: http://sourceware.org/ml/crossgcc/2009-03/msg00053.html It [the toolchain] uses current ct-ng (nightly snapshot 20090324, latest release 1.3.2 work also), glibc 2.9 (from CVS), binutils 2.19 and latest snapshot of GCC 4.4.0 (as of March 20, 2009). We have successfully built linux kernel 2.6.29 and a lot of other stuff with this toolchain. Here's the patch that adds GCC 4.4.0 to the ct-ng menu and enables it to download a 4.4.0 snapshot from ftp. Patch was adpated by me, mostly to better fit the configuration layout. /trunk/scripts/build/cc/gcc.sh | 34 22 12 0 ++++++++++++++++++++++------------ /trunk/config/cc/gcc.in | 35 30 5 0 ++++++++++++++++++++++++++++++----- 2 files changed, 52 insertions(+), 17 deletions(-) diff -r ca485f06bfa7 -r 5594b05bc2d8 config/cc/gcc.in --- a/config/cc/gcc.in Tue Mar 24 17:39:45 2009 +0000 +++ b/config/cc/gcc.in Thu Mar 26 18:47:34 2009 +0000 @@ -112,10 +112,39 @@ depends on EXPERIMENTAL select CC_GCC_4_3_or_later +config CC_V_4_4_0 + bool + prompt "4.4.0 snapshot" + depends on EXPERIMENTAL + select CC_GCC_4_3_or_later + select CC_GCC_4_4_snapshot + # CT_INSERT_VERSION_ABOVE # Don't remove above line! endchoice +config CC_GCC_4_3_or_later + bool + default n + select GMP_MPFR + +config CC_GCC_4_4_snapshot + bool + default n + +config CC_GCC_4_4_snapshot_date + string + prompt "Snapshot date" + depends on CC_GCC_4_4_snapshot + help + Enter the snapshot date in the form YYYYMMDD. + Snapshots are made every friday, at around 22:30 GMT+1, + so look at your calendar to find a suitable date. + + Also, know that crosstool-NG does *not* carry any patch + for the gcc-4.4 snapshots.
