求助，linux下c程序的简单问题

hai3qing

我在linux下编译以前同事留下来的C程序，他写好了Makefile,我直接make,但出现很多错误，我发现都是c程序在函数中定义变量产生的，比如：
程序（部分）
void* ReadThread(void* argList)
{
        struct log_device* log;
        int returnAction;
        int bStopThread = 1;//这前面定义的变量不出现错误
        log = (struct log_device*)argList;
        //int bStopThread = 1;
        while(bStopThread){
                log_message(log,"[thread]:","******************thread thread**********************");
                char * ctrlMsg;//但在这儿定义的变量就提示出错，这是怎么回事啊？急死我了
                ctrlMsg = calloc(40,sizeof(char *));
                char subCode[5];
}
}       
错误（部分）：
gcc -c  -Wall -g -I./log/include -I./db/include -I./manager/include -I./action/include  manager/src/manager.c  -o manager/obj/manager.o
manager/src/manager.c: In function `ReadThread':
manager/src/manager.c:13: parse error before `char'
manager/src/manager.c:14: `ctrlMsg' undeclared (first use in this function)
manager/src/manager.c:14: (Each undeclared identifier is reported only once
manager/src/manager.c:14: for each function it appears in.)
manager/src/manager.c:15: parse error before `char'
manager/src/manager.c:20: `sendStr' undeclared (first use in this function)
manager/src/manager.c:21: `actionNumStr' undeclared (first use in this function)
manager/src/manager.c:23: `cpContent' undeclared (first use in this function)
manager/src/manager.c:24: parse error before `int'
不知道哪儿不对，linux刚用，谢谢大家啊。

变量定义(声明) 的位置应在开始部分吧,对C来说.C++就不需这样
