33For developers using the git tree:
34
35This source tree is based on the autotools suite from GNU to simplify
36portability. Here are some things you should have on your system in order to
37compile the git repository tree :
38
39- GNU autotools (automake >=1.10, autoconf >=2.50, autoheader >=2.50)
40 (make sure your system wide "automake" points to a recent version!)
41- GNU Libtool >=2.2
42 (for more information, go to http://www.gnu.org/software/autoconf/)
5c73c59b
DG
43- GNU Gold >= 2.22
44 (Before this version we hit a known bug documented at:
45 http://sourceware.org/bugzilla/show_bug.cgi?id=11317)

47If you get the tree from the repository, you will need to use the "bootstrap"
48script in the root of the tree. It calls all the GNU tools needed to prepare the
49tree configuration.
