Visual Studio 2010 include library???

Recommended Posts

CodeExplorer

Visual Studio 2010 include library:
So I once again have a question:
I need to include:
https://github.com/jmendeth/ccv15/tree/master/libs/poco
I found this info:  https://docs.microsoft.com/en-us/cpp/build/walkthrough-creating-and-using-a-dynamic-link-library-cpp?view=vs-2019

So the first thing I do is copy "include folder" to D:\BarsWF-master\Poco
and that thing seems to work just fine.
Now the compiler complains:
1>LINK : fatal error LNK1104: cannot open file 'PocoFoundationmtd.lib'

Already tried Project Properties -> Linker -> Additional Library Directories
No good result!

you have to compile the library into a "lib" file >> PocoFoundationmtd.lib

and then include it in the linker settings for the main project

Partially got it: I also have to add PocoFoundationmtd.lib to Linker -> Input Additional Dependencies

In the release build I get this:
3>msvcprt.lib(MSVCP100.dll) : error LNK2005: "void __cdecl std::_Xlength_error(char const *)" (?_Xlength_error@std@@YAXPBD@Z) already defined in libcpmt.lib(xthrow.obj)
...
3>LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library
3>D:\BarsWF-master\\out\Release-Win32\barswf_cpu.exe : fatal error LNK1169: one or more multiply defined symbols found
3>
3>Build FAILED.

In the debug build I get this:
3>PocoFoundationmt.lib(Message.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in console_stuff.obj

Those errors break my brain out: specially the msvcprt.lib error!

double check the linker includes for the debug and release configuration, you have to edit them for each configuration

C++ can be a pain in the ass at first but it's great when you get used to it

Make sure you add the libs in the linker settings, and the headers in the C++ directories settings, additional includes

I figure it out on what to do with libs files: I simply put them in the project directory!
This works like it should.

Now about the msvcrtd thing:
It has to do with Runtime library option.
Now the problem is the speed of execution: only 5MH/second! (MH = mega hashes)
very slow considering that this is just MD5!
It has bugs: doesn't find MD5(ABCD) = cb08ca4a7bb5f9683c19133a84872ca7

You need to make sure that you also included the lib in that same settings window under 'Additional Libraries'.

You can also include it within the source manually via a pragma like this:

#pragma comment(lib, "PocoFoundationmtd.lib")

Long as the path is set properly it should find it without issue. You can also give the pragma the full path to said lib.
