[ECOS] I have a problem about ecos support "opendir" function or not? thank you~

Hi,

I was trying to run kvm (cldc 1.1) on ecos. And my host os is red hat9 running on VMware workstation 5. The target I choose when I install ecos is ˇ§i386-elfˇ¨.

I will test on linux, so I created a configuration ecos.ecc for linux (ecosconfig new linux) and make the kernel. (include and lib)

After making the ecos kernel, I was changing the cc to i386-elf-gcc of preverify tool in cldc 1.1

When making the file, there will have problem that ˇ§DIRˇ¨ is undeclared. As you can see below, the dirent.h in ecos kernel has extern ˇ§DIRˇ¨. However, there is no lib for DIR in ecos kernel.(there is no lib which declare the struct of DIR in ecos kernel)
 
So I want to ask is ecos support opendir operation? I was check on google, but it is hardly to find the same problem with me. I think is the problem happened because my ecos kernel has building in a wrong way. Or actually, ecos does not support the directory operation like opendir or readdir, etc.
Thank you ~

In /ecos/install/include/dirent.h
/* PROTOTYPES */
extern DIR *opendir( const char *dirname );
extern struct dirent *readdir( DIR *dirp );
extern int readdir_r( DIR *dirp, struct dirent *entry, struct dirent **result );

the code in cldc preverifier:
static void recurse_dir(char *dirname, char *pkgname)
{
    struct dirent *ent;
        char buf[MAXPACKAGENAME];
        char pkgbuf[MAXPACKAGENAME];
    DIR *dir = opendir(dirname);
                                                                                
    if (dir == NULL) {
        fprintf(stderr, "Can't open dir %s\n", dirname);
        exit(1);
    }
    for (ent = readdir(dir); ent; ent = readdir(dir)) {
        struct stat stat_buf;
        char *name = ent->d_name;
        int len;
                                                                                
        if (strcmp(name, ".") == 0 || strcmp(name, "..") == 0) {
            continue;
        }
