chdir is just not what you want to do, it changes the working Directory
of the running Process. However, you can use a recusive lookup with
cxxtools::Directory, consider the following example (Remember, care for
exceptions, some subdirs might not be readable).

#include <string>
#include <vector>
#include <iostream>
#include <cxxtools/fileinfo.h>
#include <cxxtools/directory.h>
void recusive_filelist(std::vector<std::string>& _vec,
cxxtools::FileInfo& _fi)
{
cxxtools::Directory dir(_fi);
for (cxxtools::DirectoryIterator it = dir.begin(); it !=
dir.end(); ++it)
{
cxxtools::FileInfo path(it.path());
if(path.type() == cxxtools::FileInfo::Directory)
{
if(path.name() != "." && path.name() != "..")
recusive_filelist(_vec, path);
}
else
_vec.push_back(path.path());
}
}
int main(void)
{
std::vector<std::string> vec;
cxxtools::FileInfo startdir("/opt");
recusive_filelist(vec, startdir);
for(std::vector<std::string>::const_iterator it = vec.begin();
it != vec.end(); it++)
std::cout << "name: " << *it << "\n";
return 0;
}
