lafilefixer (C) 2009 Peter Alfredsen <loki_val@gentoo.org> | |
Released under the MIT/X11 license. | |
Usage: lafilefixer [OPTION] [FILE|DIR]... | |
Fix .la libtool archives to list libraries, not .la files in dependency_libs and | |
do some minor fixups, moving -pthread to inherited_linker_flags if available and | |
eliminating duplicate library listings. | |
By default, lafilefixer is recursive, fixing all .la files in all subdirectories | |
so if you want to fix only a single file, it must be specified in full. | |
Options: | |
-h, --help Display this text and exit. | |
--justfixit Choose some reasonable dirs, such as /usr/lib*, etc. , | |
find all .la files and fix them to not use .la files | |
for linking | |
--license Display the license and exit. | |
