I have to make a project which asks me to create a program that will compile a C project by recursively descending into directories and launching processes which compile a file of code by calling GCC and look through directories and launch a new process for every “.c” file in the current directory that process will call gcc on the .c file making a .o file.
I have written this code so far to list the directories first
I am having trouble checking what files are .c and how to convert them to .o
can someone help me with some relevant information/links that I can refer to?
void listdir(const char *name, int indent)
{
DIR *dir;
struct dirent *entry;
if (!(dir = opendir(name)))
return;
while ((entry = readdir(dir)) != NULL) {
if (entry->d_type == DT_DIR) {
char path[1024];
if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0)
continue;
snprintf(path, sizeof(path), "%s/%s", name, entry->d_name);
printf("%*s[%s]n", indent, "", entry->d_name);
listdir(path, indent + 2);
} else {
printf("%*s- %sn", indent, "", entry->d_name);
}
}
closedir(dir);
}
int main(void) {
listdir(".", 0);
return 0;
}
