But I hope to finish the 'msgrcv08' test by LTP automatically. To recompile the whole LTP-Lib in 32-bit only for this one case is not my expected. I tend to give up the testcase if we don't have any other way. :( though it works well on 64-bit system: --------------------------------------------------- # ./configure CFLAGS=-m32 # cd testcases/kernel/syscalls/ipc/msgrcv/ # make make -C ../lib -f "/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib/Makefile" all make[1]: Entering directory `/root/ltp-test/testcases/kernel/syscalls/ipc/lib' make[1]: Nothing to be done for `all'. make[1]: Leaving directory `/root/ltp-test/testcases/kernel/syscalls/ipc/lib' gcc -m32 -g -O2 -fno-strict-aliasing -pipe -Wall -W -m32 -Wold-style-definition -I/root/ltp-test/testcases/kernel/include -I/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -I../../../../../include -I../../../../../include -L/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -L../../../../../lib msgrcv01.c -lltp -lipc -o msgrcv01 gcc -m32 -g -O2 -fno-strict-aliasing -pipe -Wall -W -m32 -Wold-style-definition -I/root/ltp-test/testcases/kernel/include -I/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -I../../../../../include -I../../../../../include -L/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -L../../../../../lib msgrcv05.c -lltp -lipc -o msgrcv05 gcc -m32 -g -O2 -fno-strict-aliasing -pipe -Wall -W -m32 -Wold-style-definition -I/root/ltp-test/testcases/kernel/include -I/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -I../../../../../include -I../../../../../include -L/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -L../../../../../lib msgrcv06.c -lltp -lipc -o msgrcv06 gcc -m32 -g -O2 -fno-strict-aliasing -pipe -Wall -W -m32 -Wold-style-definition -I/root/ltp-test/testcases/kernel/include -I/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -I../../../../../include -I../../../../../include -L/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -L../../../../../lib msgrcv08.c -lltp -lipc -o msgrcv08 gcc -m32 -g -O2 -fno-strict-aliasing -pipe -Wall -W -m32 -Wold-style-definition -I/root/ltp-test/testcases/kernel/include -I/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -I../../../../../include -I../../../../../include -L/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -L../../../../../lib msgrcv04.c -lltp -lipc -o msgrcv04 gcc -m32 -g -O2 -fno-strict-aliasing -pipe -Wall -W -m32 -Wold-style-definition -I/root/ltp-test/testcases/kernel/include -I/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -I../../../../../include -I../../../../../include -L/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -L../../../../../lib msgrcv02.c -lltp -lipc -o msgrcv02 gcc -m32 -g -O2 -fno-strict-aliasing -pipe -Wall -W -m32 -Wold-style-definition -I/root/ltp-test/testcases/kernel/include -I/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -I../../../../../include -I../../../../../include -L/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -L../../../../../lib msgrcv07.c -lltp -lipc -o msgrcv07 gcc -m32 -g -O2 -fno-strict-aliasing -pipe -Wall -W -m32 -Wold-style-definition -I/root/ltp-test/testcases/kernel/include -I/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -I../../../../../include -I../../../../../include -L/root/ltp-test/testcases/kernel/syscalls/ipc/msgrcv/../lib -L../../../../../lib msgrcv03.c -lltp -lipc -o msgrcv03 [root@hp-dl388g8-23 msgrcv]# ./msgrcv08 msgrcv08 1 TFAIL : msgrcv08.c:45: Bug: No message of desired type.
