Compiling boost with zlib on windows
boost, boost-iostreams, c++, zlib
Solution
The linker actually tells you that it cannot find the "basic_gzip_decompressor". The reason is because you have zlib not built into your boost libraries.
(This SO question claims to have a solution without having to build zlib into boost libs)
I agree that the documentation on this is a bit terse, but it is found here. If your normal build commandline is like this:
b2 -j15 --toolset=msvc --build-type=complete stage
add the ZLIB definitions to make it build with zlib
b2 -j15 --toolset=msvc --build-type=complete stage -s ZLIB_SOURCE="C:\zlib-1.2.8" -s ZLIB_INCLUDE="C:\zlib-1.2.8"
you can relatively quickly check whether it works (before compilation is complete) when you look for the configuration check output. There it should say something like:
- zlib : yes (cached)
Problem
Is there is good tutorial on how to compile boost with zlib on windows. I looked over boost reference, but it's vague and not enough. I did download zlib dll and source code and made reference in visual studio. I have link error on ``` gzip_decompressor(); ``` complete code: ``` using namespace boost::iostreams; using namespace std; std::ifstream file("hello.gz", std::ios_base::in | std::ios_base::binary); filtering_streambuf < input > in; in.push(gzip_decompressor()); in.push(file); boost::iostreams::copy(in, std::cout); ``` I am getting this error, Error 11 error LNK2019: unresolved external symbol "_declspec(dllimport) public: __thiscall boost::iostreams::detail::gzip_header::~gzip_header(void)" (__imp??1gzip_header@detail@iostreams@boost@@QAE@XZ) referenced in function "public: __thiscall boost::iostreams::basic_gzip_decompressor \>::~basic_gzip_decompressor >(void)" (??1?$basic_gzip_decompressor@V?$allocator@D@std@@@iostreams@boost@@QAE@XZ) –
