Ok, here's my entire script. As mentioned in the comments it works fine if size=5e5. It also runs fine if size=5e6, but then the resulting file is corrupt (i.e. cannot be gunzipped with the gzip utility). Try it out. I'm using Visual Studio 2008 in a Windows XP machine.
#include
#include #include using namespace std; namespace io = boost::iostreams;
int main() { //Set filename string outfile = "c:/outfile.bin.gz";
//Set filesize int size = int(5e6); // <- If I change this to '5e5' instead of '5e6', everything works just fine.
//Declare memory block to be compressed to file char* memblock = new char [size];
//Create a filtering_ostream out io::filtering_ostream out;
//Assigns the gzip_compressor to out out.push(io::gzip_compressor());
//Assigns out as a file sink out.push(io::file_sink(outfile));
//Write memblock to out out.write(memblock, size);
//Clean up delete[] memblock; io::close(out); //Note, also tried 'out.close();', 'io::close(out, ios_base::out);' and 'close(out);'. Same result.
return 0; }
Works just fine on linux gcc 4.3.2 boost 1.45. with 5e5, 5e6 and 5e7 size. As a guess, I'd delete memblock after closing the out to be on a safe side, maybe it helps. -- Slava
