[PATCH 2/2] configure.ac: Move link only flags out of CFLAGS and into LDFLAGS.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On the ARM gcc 4.2.2 many
"--as-needed: linker input file unused because linking not done"
style warnings appear when libtool is using compile mode.

In order to silence these warnings and be "correct", the flags that
only make sense for linking are moved into LDFLAGS.
