I am using the header zip.hpp (can be found here https://markand.bitbucket.io/libzip/index.html or here http://hg.markand.fr/libzip/file) to zip some files.
To remove the raw files afterwards, I use remove("myfile.txt").
Apparently, zip.hpp zips the files at the end of runtime, thus it cannot find the file and doesnt create a zip-folder. If I leave out remove("myfile.txt"), everything works fine, except for that I have a couple of files flying around that I only want to have in their zipped form.
Do you have any idea on how to force libzip to write the zip-files?
I would expect if I delete the archive-instance, it should force the creation, but apparently the libzip::Archive-class doesn't have a destructor (at least I can't find one and delete archive throws many errors)
My basic code looks like this:
#include <fstream>
#include <zip.h>
#include "lib/zip.hpp"
int main () {
libzip::Archive archive("output.zip", ZIP_CREATE);
std::ofstream outfile ("myfile.txt");
outfile << "Hello World\n";
outfile.close();
archive.add(libzip::source::file("myfile.txt"), "myfile2.txt");
// delete archive; // throws an error...
// remove("myfile.txt");
// if left out, output.zip gets created otherwise nothing is created
return 0;
}
The libzip::Archive will write its contents when it goes out of scope. So all you need to do is introduce an aditional scope before removing the file.
#include <fstream>
#include <zip.h>
#include "lib/zip.hpp"
int main () {
{ // Additional scope
libzip::Archive archive("output.zip", ZIP_CREATE);
std::ofstream outfile ("myfile.txt");
outfile << "Hello World\n";
outfile.close();
archive.add(libzip::source::file("myfile.txt"), "myfile2.txt");
} // Archive is written now.
remove("myfile.txt");
return 0;
}
