Linking errors while migrating code from VS 2003 to VS 2005

[ptc-3191571]

Hello,

I am having a working code of protk in VS 2003 I am now migrating it to VS 2005.I solved most of the errors but stuck up at "Error1error LNK2019: unresolved external symbol _errno referenced in function _ptc_exitprotk_dll.lib" this error message.I have done all the required project settings

Libs include-protk_dll.libprodev_dll.lib protoolkit.libprodevelop.lib wsock32.lib kernel32.lib user32.lib advapi32.lib winspool.lib mpr.lib psapi.lib
Code Generation - /MTd

I guess the solution is around this things only but not able to find the rite cord.

help needed

I am not sure of theissuebut I can pass along my lib filesthat I am using on working projects.

For wildfire5I am currently compiling in VS2008.

additionallib files with /MTdsetting are: protk_dllmd.lib wsock32.lib mpr.lib netapi32.lib psapi.lib ws2_32.lib

linker command line additional options :/force:multiple

If this is Wildfire 5 I believe you are missing the ws2_32.lib and you need to change to the pro****md.lib files.ws2_32.lib was a new lib file introduced with WF5. This is found under the summary of technical changes in the manual.

I would definitely switch

protk_dll.lib to protk_dllmd.lib

If you switched to cpp files instead of c files then you may experience an issue with needing to declare your hookfunctions as extern in order for the dlls to find the declarations.

extern "C" int user_initialize(int argc, char *argv[], char *szVersion, char *szBuild, wchar_t *wzErrBuf) {

}

extern "C" void user_terminate() {

}

Currently VS2003 is the supported compiler for wildfire 3.0 so you may be in some uncharted territory.
