Issue in adding syscalls in Android libc

Question

Please help. I'm working with Android marshmallow (6.0) source code and I need a linux message queue and shared memory related system call support for an application to port. Formerly I was using Kitkat source code and in that it was working.

The steps I did for that is:

1. Added syscalls in /BSP/Bionic/libc/SYSCALLS.TXT
2. Generated asm stubs using gensyscalls.py script.
3. Compiled without error libc but the libc.so generated is not containing the added symbols.

Thanks in advance.

Syscalls added in /BSP/Bionic/libc/SYSCALLS.TXT:

• int semctl(int semid, int semnum, int cmd, ...) all
• int semget(key_t key, int nsems, int semflg) all
• int semop(int semid, struct sembuf* sops, size_t nsops) all
• void* shmat(int shmid, const void* shmaddr, int shmflg) all
• int shmctl(int shmid, int cmd, struct shmid_ds* buf) all
• int shmdt(const void* shmaddr) all
• int shmget(key_t key, size_t size, int shmflg) all
• int msgctl(int msqid, int cmd, struct msqid_ds *buf) all
• int msgget(key_t key, int msgflg) all
• int msgrcv(int msqid, void* msgp, size_t msgsz, long int msgtyp, int msgflg) all
• int msgsnd(int msqid, const void* msgp, size_t msgsz, int msgflg) all
