C ++ POCO lib Binding Error while trying to static link VS9 express

Preview: binding error while trying to static link VS9 express

I am trying to compile a simple application in visual studio 2008 express based on Poco::Process . But I get communication errors.

Here is my simple code configured as a console application:

 #include "Poco/Foundation.h" #include "Poco/Process.h" #include "Poco/Pipe.h" #include "Poco/PipeStream.h" using Poco::Process; using Poco::ProcessHandle; using Poco::Pipe; using Poco::PipeInputStream; using Poco::PipeOutputStream; int main(int argc, char** argv) { std::string cmd = "hostname"; std::vector<std::string> args; args.push_back("--help"); ProcessHandle ph = Process::launch(cmd, args); int rc = ph.wait(); return 0; }

I added preprocess flags:

 Foundation_EXPORTS POCO_STATIC PCRE_STATIC

And I am contacting:

 PocoFoundationmt.lib

with multi-threaded Debug DLL (/ MDd), but I get this binding error:

The library "PocoFoundationmt.lib" that you use is built with the "release static" mode. From the project you are running, it looks as if you need a debug version of the library, which should be "PocoFoundationmtd.lib".

As you can see from the error log, there is a conflict when linking. That is, you said that the executable is MDd, but you are linking to the release version library. Make sure that in ProjectProperties-> Linker you do not link to other libraries and make a link to "PocoFoundationmtd.lib" . Be sure to select "Debug" instead of "Release" at the top (start button) of your project. Also specify POCO_STATIC .

Make sure you create both the Poco libraries and your project in the same C runtime (static / dynamic, debug / release, multi-threaded).

I just did it, as Chadwick said, you don’t need the Foundation_EXPORTS preprocessor flag.

Also, if you installed the additional lib directory in poco lib, you do not need to specify the type dll ie MT, Debug, etc.

You only need POCO_STATIC as a preprocessor flag.
