how do I fix it? I am working on wrapping a large number of .h and .lib files from native C++ to Managed C++ for eventual use as a referenced .dll in C#. I have the .lib files linked in and everything has been going smoothly so far. Upon wrapping the latest .h file, I hit a snag when 2 functions came back with the link error: error LNK2019: unresolved external symbol __imp__htonl@4 referenced error lnk2019 unresolved external symbol visual studio 2010 in function "public: void __thiscall Field::setCharacter(unsigned char,int)" (?setCharacter@Field@@QAEXEH@Z) myutils.lib I have referenced myutils.lib in the linker options, so that shouldn't be the issue. What's strange is that I have about 20 functions in this particular .h file and all of the rest are linking just fine except for 3 functions. Any ideas? c++ linker unresolved-external share|improve this question edited Apr 25 at 21:05 jww 35.4k21112222 asked Jul 20 '09 at 14:21 TomO 183617 marked as duplicate by Roddy, Jonathan Leffler, brenjt, MartinStettner, HaskellElephant Oct 22 '12 at 0:11 This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question. Could you post the code of the functions that aren't linking (and maybe of one of the ones that are for comparison)? –Sean Jul 20 '09 at 14:27 "... so that shouldn't be the issue." -> "Should" is a mighty dangerous word in most cases ;) –Chris Tonkinson May 20 '10 at 15:07 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote accepted The missing symbol is __imp__htonl@4, which is a C++ mangled name for htonl, which is a function that converts a long value from host to network order. The @4 is used to mangle the input paramete

My project has lib's that http://stackoverflow.com/questions/1153900/unresolved-external-symbol I didn't write (I am putting together a ui wrapper for a console application.) How do I figure out what symbols are not being resolved? And how to fix this? Thank you guys sooo much! Frice2014 Oct 17, 2011 at 1:27am UTC webJose (2948) You don't need to figure out which http://www.cplusplus.com/forum/windows/52669/ symbols are unresolved: The errors are telling you exactly which ones are: _ntohs, _ntohl and _htonl, and the message even tells you which functions contain them. What you need to do is configure the linker to use the lib files given to you. You can use that with #pragma comment(lib, "thelibgoeshere"), or you can configure the additional libs using the project's properties. Personally, I would use the #pragma option. Oct 17, 2011 at 6:18am UTC modoran (2060) I myself prefer #pragma statement too, don't care if is only supported by Visual Studio. Why ? Because it is much easier than messing with project settings in debug/release x86/x64 builds every time. @OP: The library you need is winsock2, Ws2_32.lib Topic archived. No new replies allowed.
