Hi,
Though i am not expert in compiling LTP, but i am trying to cross compile
current LTP for arm. Here is how i am configuring
Go to root folder of ltp and execute
./configure AR=arm-linux-gnueabi-ar CC=arm-linux-gnueabi-gcc
RANLIB=arm-linux-gnueabi-gcc-ranlib-4.7 STRIP=arm-linux-gnueabi-strip
--host=arm-linux --target=arm-linux CFLAGS="-static" LDFLAGS="-static
-pthread"
Failing at
configure: error: cannot run /bin/sh ./config.sub
configure: error: ./configure failed for utils/ffsb-6.0-rc2
But still i ignored these messages and tried building some specific tests.
Ex: realtime tests
Go to testcases/realtime/func/sched_football and run make. Here make failed
due to `ld: cannot find -lrealtime`
arm-linux-gnueabi-gcc -static -g -O2 -fno-strict-aliasing -pipe -Wall -W
-static -Wold-style-definition -D_GNU_SOURCE
-I/local/mnt/workspace/Srikanth/ltp-full-20140828/testcases/realtime/include
-I/local/mnt/workspace/Srikanth/ltp-full-20140828/testcases/realtime/include
-I../../../../include -I../../../../include -static -pthread
-L/local/mnt/workspace/Srikanth/ltp-full-20140828/testcases/realtime/lib
-L../../../../lib sched_football.c -lrealtime -lpthread -lrt -lm -o
sched_football

Pointers from anyone who tried cross compiling ltp for arm would really
helpful.
TIA.
