我正在使用该代码创建一个进程:

CreateProcess(NULL, "process.exe", NULL, NULL, TRUE, 0, NULL, NULL, %ini_processo, %processo_info);

我需要我的代码在恢复之前等待我的进程完成.使用C++的方法是什么？

我在FirstApp.java中保存了这段代码:

class FirstApp {
    public static void main (String[] args) {
        System.out.println("Hello World");
    }
}

这是我在尝试编译和运行时得到的:

$ javac FirstApp.java
$ java FirstApp
Exception in thread "main" java.lang.UnsupportedClassVersionError: FirstApp : Unsupported major.minor version 51.0

我做错了什么？

我想知道在与Sourcery工具链进行ARM交叉编译时是否有可能将我的应用程序链接到libssh。我的主机系统是Ubuntu x86_64

:~/c/ssh$ arm-none-linux-gnueabi-gcc ssh.c -o arm `pkg-config --cflags --libs libssh`
cc1: warning: include location "/usr/local/include" is unsafe for cross-compilation [-Wpoison-system-directories]
/home/user/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_GNU_Linux/bin/../lib/gcc/arm-none-linux-gnueabi/4.6.1/../../../../arm-none-linux-gnueabi/bin/ld: warning: library search path "/usr/local/lib" is unsafe for cross-compilation
/usr/local/lib/libssh.so: file not recognized: File format not recognized
collect2: ld returned 1 exit status

我的应用使用gcc使用以下命令可以正常编译：

gcc ssh.c -o ssh -lssh

交叉编译时添加相同的-lssh标志会导致以下错误：

:~/c/ssh$ arm-none-linux-gnueabi-gcc ssh.c -o arm -lssh
ssh.c:2:49: fatal error: libssh/libssh.h: No such file or directory
compilation terminated.
