Hi
I want to cross compile ltp for arm platform also my entire executable
should be statically linked:
My ARM tool chain is installed in "/usr/local/arm/arm-2009q3/"
My LTP source is in "/home/user/test_apps/ltp/arm/ltp-full-20130904/".
I followed the below steps,
------------------------------------------------------------------------------------------------------------------------------
export ARCH=arm
export CROSS_COMPILER=/usr/local/arm/arm-2009q3/bin/arm-none-linux-gnueabi
export CC=$CROSS_COMPILER-gcc
export LD=$CROSS_COMPILER-ld
export AR=$CROSS_COMPILER-ar
export STRIP=$CROSS_COMPILER-strip
export RANLIB=$CROSS_COMPILER-ranlib
./configure --host=arm-linux
--prefix=/home/user/test_apps/ltp/arm/ltp-full-20130904/install
--exec-prefix=/home/user/test_apps/ltp/arm/ltp-full-20130904/install
LDFLAGS="-static"
make
-------------------------------------------------------------------------------------------------------------------------------
My Make fails as follows,
(I get "undefined reference to" all pthread calls in
"/testcases/kernel/syscalls/mq_notify".)
/usr/local/arm/arm-2009q3/bin/arm-none-linux-gnueabi-gcc -g -O2 -g -O2
-fno-strict-aliasing -pipe -Wall -D_FORTIFY_SOURCE=2
-I/home/user/test_apps/ltp/arm/ltp-full-20130904/testcases/kernel/include
-I../../../../include -I../../../../include -static -L../../../../lib
mq_notify01.c -lltp -lpthread -lrt -o mq_notify01
/usr/local/arm/arm-2009q3/bin/../arm-none-linux-gnueabi/libc/usr/lib/librt.a(mq_notify.o):
In function `mq_notify':
mq_notify.c:(.text+0x68): undefined reference to `pthread_once'
I don’t get this error if I don't put LDFLAGS="-static" in configure
command,
if I go to "testcases/kernel/syscalls/mq_notify" and try to build using the
command whatever the make is trying to do as follows,
------------------------------------------------------------------------------------------------------------------
/usr/local/arm/arm-2009q3/bin/arm-none-linux-gnueabi-gcc -g -O2 -g -O2
-fno-strict-aliasing -pipe -Wall -D_FORTIFY_SOURCE=2
-I/home/user/test_apps/ltp/arm/ltp-full-20130904/testcases/kernel/include
-I../../../../include -I../../../../include -static -L../../../../lib
mq_notify01.c -lltp -lpthread -lrt -o mq_notify01
----------------------------------------------------------------------------------------------------------------
obviously I get the same error, but if I rearrange the pthread linker flag
at the last as follows
-----------------------------------------------------------------------------------------------------------------
/usr/local/arm/arm-2009q3/bin/arm-none-linux-gnueabi-gcc -g -O2 -g -O2
-fno-strict-aliasing -pipe -Wall -D_FORTIFY_SOURCE=2
-I/home/user/test_apps/ltp/arm/ltp-full-20130904/testcases/kernel/include
-I../../../../include -I../../../../include -static -L../../../../lib
mq_notify01.c -lltp -lrt -o mq_notify01 -lpthread
---------------------------------------------------------------------------------------------------------------
The compilation succeeds now
Can someone help me how to cross compile ltp for arm with statically
linking?
