[Linphone-users] mediastreamer: unsafe library path used in cross-compilation

[Jörg Krause]

Hi,

when cross-compiling mediastreamer 2.15.1 an unsafe library path is
used when linking 'libmediastreamer_voip.la':

arm-linux-gcc: ERROR: unsafe header/library path used in cross-
compilation: '-L/usr/lib'
"""

The unsafe library path is set for "-rpath". Setting the rpath to a
path where host libraries are located is unsafe for cross-compilation
as the linker might link against the host, instead the target libraries
(located in a sysroot directory).
