I've built standalone toolchian for imx6ul, and install it.
When I compiled openssh using the toolchain and running it on target board, then I got “Segmentation fault” error.
I think it caused by CFLAGS or LDFLAGS but I don't know how to modify it.
So should someone help me, thank you!
followed is my cross-compile flowchart:
$ git branch
* V_7_2
master
$ autoconf
$ autoheader
$ export CFLAGS="$CFLAGS -I/data/lib/openssl-1.0.2f/include/ -fPIC"
$ export LDFLAGS="-L/data/lib/openssl-1.0.2f/"
$ ./configure --with-ssl-dir=/data/modules/c0402.git/lib/openssl-1.0.2f --with-zlib=../zlib.git/ --host=arm-poky-linux-gnueabi

$ make
