Revision 1.1, Fri Feb 1 05:27:38 2019 UTC (5 years, 4 months ago) by jsg
add libelf from elftoolchain r3669 A 2 clause BSD licensed implementation of the SVR4 ELF API also implemented by mr511.de libelf (devel/libelf in ports) and elfutils. It is being added to base to allow Mesa to use it in future. shlib major is higher than devel/libelf and pkg-config version is 0.8.2 to pass a glib2 configure test so this can replace the use of devel/libelf in ports. |
