24 To use these scripts, you really need to understand how to build a gcc as a
eb230fa7d28e Prepare for migration to hg
lost
parents:
diff changeset
25 cross compiler. The basics are that you put the as, ld, and ar scripts
eb230fa7d28e Prepare for migration to hg
lost
parents:
diff changeset
26 whereever you plan to put your cross-development binaries. Then, when
eb230fa7d28e Prepare for migration to hg
lost
parents:
diff changeset
27 building the cross compiler, you tell it where the scripts are.
