解決"dereferencing pointer to incomplete type struct ucontext"問題
參考資訊：
1. qemu-devel
問題如下：
qemu/user-exec.c: In function ‘cpu_resume_from_signal’:
qemu/user-exec.c:70:55: error: dereferencing pointer to incomplete type ‘struct ucontext’
sigprocmask(SIG_SETMASK, (struct ucontext*)&uc->uc_sigmask, NULL);
^~
qemu/user-exec.c: In function ‘cpu_x86_signal_handler’:
qemu/user-exec.c:211:41: error: dereferencing pointer to incomplete type ‘struct ucontext’
#define PC_sig(context) ((context)->uc_mcontext.gregs[REG_RIP])
^~
qemu/user-exec.c:230:10: note: in expansion of macro ‘PC_sig’
pc = PC_sig(uc);
^~~~~~
qemu/user-exec.c:235:1: warning: control reaches end of non-void function [-Wreturn-type]
}
^
make[1]: *** [qemu/rules.mak:18: user-exec.o] Error 1
make: *** [Makefile:84: subdir-i386-linux-user] Error 2
P.S. 解法：把struct ucontext都替換成ucontext_t即可
