When cross-compiling with toolchains that validate things like headers and libraries paths, we were getting errors like: sh-linux-gnu-gcc: ERROR: unsafe header/library path used in cross-compilation: '/lib' That's because there was an error in the configure script that was not generating ldflags correctly, and the generated Makefile was trying to link with -L/lib. Also, it is necessary to pass a prefix when compiling with libjpeg and libtiff support. A patch has already been sent upstream.

Subject: [PATCH 1/1] Fix compile error when cross-compiling.
|
|
|
|
When cross-compiling with libjpeg enabled, we can get errors like the
|
|
following when linking:
|
|
|
|
sh-linux-gnu-gcc: ERROR: unsafe header/library path used in
|
|
cross-compilation: '/lib'
|
|
|
|
That's because there is an error in the configure script that are not
|
|
generating ldflags correctly, and are trying to link with -L/lib.
