It’s me again. I’m back with an all new project and an all new problem.
I am trying to implement something for Growl. Either using a static or shared library (both are provided). I included the necessary header and linked to the library. (2 ways actually, once through the project properties and the other through a pragma statement). However, im still receiving the following linker errors:
error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall Growl::Growl(enum Growl_Protocol,char const * const,char const * const,char const * * const,int)" (__imp_??0Growl@@QAE@W4Growl_Protocol@@QBD1QAPBDH@Z)
error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall Growl::~Growl(void)" (__imp_??1Growl@@QAE@XZ)
fatal error LNK1120: 2 unresolved externals
The line of code that is causing these linker errors is this line:
const char *n[2] = { "username" , "password" };
Growl *growl = new Growl(GROWL_TCP,NULL, "Appname", (const char **const)n,2);
The header file is being included at the top of the file and I am linking with the following line:
#include "..\\..\\..\\libs\\Growl\\growl++.hpp"
#pragma comment(lib, "..\\..\\..\\libs\\Growl\\libgrowl-static++.lib")
The header source can be found here:
https://github.com/psinnott/gntp-send/blob/master/headers/growl%2B%2B.hpp
I retrieved the pre-built binaries from the following page:
https://github.com/psinnott/gntp-send/wiki/Windows
Some extra info: I do have my Project Propeties character set to use Multi-Byte Character Set, im under the assumption this shouldn’t affect anything. This is also a Win32 Console application.
Where am I going wrong?
Update:
Found this via google:
http://groups.google.com/group/growl-for-windows/browse_thread/thread/6c48a62454d062f1
Followed the instructions:
Added the libgrowlstatic.lib (alongside libgrowlstatic++.lib)
Added the pre-processor definitions, GROWL_STATIC and GROWL_CPP_STATIC
Got lots of error including:
LINK : warning LNK4098: defaultlib 'MSVCRTD' conflicts with use of other libs; use /NODEFAULTLIB:library
LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other libs; use /NODEFAULTLIB:library
fatal error LNK1169: one or more multiply defined symbols found
So I added the following line to Project properties, Linker, Command Line:
/NODEFAULTLIB:MSVCRTD /NODEFAULTLIB:LIBCMT
Now im getting alot more errors including some of the following:
libgrowl-static.lib(tcp.obj) : error LNK2019: unresolved external symbol _atoi referenced in function _growl_tcp_parse_hostname
libgrowl-static.lib(tcp.obj) : error LNK2019: unresolved external symbol _strchr referenced in function _growl_tcp_parse_hostname
libgrowl-static.lib(growl-static.obj) : error LNK2019: unresolved external symbol _fseek referenced in function _growl_tcp_register
libgrowl-static.lib(growl-static.obj) : error LNK2019: unresolved external symbol _fopen referenced in function _growl_tcp_register
libgrowl-static.lib(growl-static.obj) : error LNK2019: unresolved external symbol _strcpy referenced in function _growl_udp_notify
Been at this for several hours and can’t seem to figure it out. 10+ views and no replies?
I swear im not being lazy. I looked into one of the answers provided about libraries but didn’t have much luck. Nothing explained why this is acting the way it is. Please help!
This is working for me. It assumes you want to use the static libraries and not the dll.
