need help using boost bzip2 filter on Windows (or zlib filter)
Hello all, I have the following code simple code to compress/uncompress a string: #include <iostream> #include <boost/iostreams/copy.hpp> #include <boost/iostreams/device/back_inserter.hpp> #include <boost/iostreams/filter/bzip2.hpp> #include <boost/iostreams/filtering_stream.hpp> using namespace std; int main() { string message = "this is a test message!"; cout << "message: " << message << endl; string compressed; boost::iostreams::filtering_streambuf<boost::iostreams::output> out; out.push(boost::iostreams::zlib_compressor()); out.push(boost::iostreams::back_inserter(compressed)); boost::iostreams::copy(boost::make_iterator_range(message), out); cout << "compressed message: " << compressed << endl; boost::iostreams::filtering_streambuf<boost::iostreams::input> in; in.push(boost::iostreams::zlib_decompressor()); in.push(boost::make_iterator_range(compressed)); string decompressed; boost::iostreams::copy(in, boost::iostreams::back_inserter(decompressed)); cout << "decompressed message: " << decompressed << endl; } but I get the following linking error: 1>------ Build started: Project: bzip2_compression_test, Configuration: Debug Win32 ------ 1>Compiling... 1>bzip2_test.cpp 1>Linking... 1>LINK : fatal error LNK1104: cannot open file 'libboost_bzip2-vc90-mt-gd-1_39.lib' 1>Build log was saved at "file://d:\compression\BoostCompression2\Debug\BuildLog.htm" 1>bzip2_compression_test - 1 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== I tried following the instructions on this page: http://www.boost.org/doc/libs/1_40_0/libs/iostreams/doc/installation.html so I defined these environment variables: BZIP2_BINARY = libbz2.lib BZIP2_INCLUDE = D:\bzip2-1.0.5 BZIP2_LIBPATH = D:\bzip2-1.0.5\Debug BZIP2_SOURCE = D:\bzip2-1.0.5 I also tried a similair example with zlib and I get the same error: 1>------ Build started: Project: libz_compression_test, Configuration: Debug Win32 ------ 1>Compiling... 1>zlib_test.cpp 1>Linking... 1>LINK : D:\Debug\libz_compression_test.exe not found or not built by the last incremental link; performing full link 1>LINK : fatal error LNK1104: cannot open file 'libboost_zlib-vc90-mt-gd-1_39.lib' 1>Build log was saved at "file://d:\\compression\libz_compression_test\Debug\BuildLog.htm" 1>libz_compression_test - 1 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== Any ideas how I can fix this?

Does the file libboost_bzip2-vc90-mt-gd-1_39.lib exist? Have you set the library path in the IDE? In Christ, Steven Watanabe
Hello Steven, No that file does not exist. I thought I could just link to my normal bzip2 or zlib library I built myself? I tried setting BOOST_ALL_NO_LIB to 1 so it would not autolink, but now I get these errors on my zlib test program: 1>------ Build started: Project: libz_compression_test, Configuration: Debug Win32 ------ 1>Linking... 1>zlib_test.obj : error LNK2001: unresolved external symbol "int const boost::iostreams::zlib::default_compression" (?default_compression@zlib@iostreams@boost@@3HB) 1>zlib_test.obj : error LNK2001: unresolved external symbol "int const boost::iostreams::zlib::deflated" (?deflated@zlib@iostreams@boost@@3HB) 1>zlib_test.obj : error LNK2001: unresolved external symbol "int const boost::iostreams::zlib::default_strategy" (?default_strategy@zlib@iostreams@boost@@3HB) 1>zlib_test.obj : error LNK2019: unresolved external symbol "protected: __thiscall boost::iostreams::detail::zlib_base::~zlib_base(void)" (??1zlib_base@detail@iostreams@boost@@IAE@XZ) referenced in function __unwindfunclet$??0?$zlib_compressor_impl@V?$allocator@D@std@@@detail@iostreams@boost@@QAE@ABUzlib_params@23@@Z$0 1>zlib_test.obj : error LNK2019: unresolved external symbol "protected: __thiscall boost::iostreams::detail::zlib_base::zlib_base(void)" (??0zlib_base@detail@iostreams@boost@@IAE@XZ) referenced in function "public: __thiscall boost::iostreams::detail::zlib_compressor_impl<class std::allocator<char> >::zlib_compressor_impl<class std::allocator<char>

Does the file libboost_bzip2-vc90-mt-gd-1_39.lib exist? Have you set the library path in the IDE?

I tried following the instructions on this page:

so I defined these environment variables:
BZIP2_BINARY = libbz2.lib BZIP2_INCLUDE = D:\bzip2-1.0.5 BZIP2_LIBPATH = D:\bzip2-1.0.5\Debug BZIP2_SOURCE = D:\bzip2-1.0.5
I was also perplexed by those instructions; The variables are boost.build variables, not environmental variables. Please use bjam .... -sBZIP2_SOURCE=D:\bzip2-1.0.5 -sZLIB_SOURCE=... in order to get libboost_bzip2 and libboost_zlib compiled. Cheers, Mikko

Actually, environment variables should work fine. It's not clear from the above report whether the variables were defined when building Boost itself, and whether the libboost_bzip2... library was produced. - Volodya
I actually installed Boost with the BoostPro package. Maybe that doesnt allow me to build those libraries? I did not have those environment variables set at the time however. Thanks, Christina Vladimir Prus-3 wrote:

Is libboost_bzip2-vc90-mt-gd-1_39.lib present in whatever directory you have installed to? If not, then: - BoostPro packages do not include those libs, and - setting any environment variables will not help. You probably need to get sources, and build it. - Volodya
