Title: Linker Error!!!
Post by: pabon on July 06, 2011, 09:18:42 pm

Platform: Windows7 32bit
Compiler Visual Studio 2010/Windows SDK
Codeblocks version 10.5
wxWidgets-2.8.12

I recently installed/setup C::B to use VS2010 as my compilier/linker. I can sucessfully create/run a win32 console app. I can also create/run a win32GUI app,but when I try to create a basic wxWidget app(creating the wxsmith tutorial app). I get the following linker error:

LINK : fatal error LNK1146: no argument specified with option '/LIBPATH:'

I have setup my wx global variable to point to my installation of wxWidgets - C:\wxWidgets-2.8.12 and I've also setup the wx/Lib to point to C:\wxWidgets-2.8.12\lib\vc_lib. My linker is also set up to point to that library location.
The following is the contents of my build log. Any assistance is greatly appreciated.

If you look the first line of the Linker output the first /LIBPATH directive has no argruments. I don't know where that is comming from. Please help. Thanks in advance.

Check Compiler and Debug Settings for bad or empty lines in
"search directories" -> "linker"

Check Project Build Options for the same under all the targets
"search directories" -> "linker"

Checked all search directories, no blank or empty lines.

Thanks for your help..

Under Project Build Options
under linker settings
Check other linker options for /LIBPATH

Also check the same under Compiler and Debugger Settings

the string '/LIBPATH' is not included in any of the linkers options setting for any build.

Thanks again Tim

NOTE: Confirm you set the wx global variable correctly under Global Variables.
Confirm you used it right also.

The following is NOT normally the correct thing to do.

Quote

I've also setup the wx/Lib to point to C:\wxWidgets-2.8.12\lib\vc_lib.

IF Global Variable is right your config is likely wrong.

I suggest renaming your code::blocks config file and trying to setup Code::Blocks again to use MSVS.

Under %APPDATA%\codeblocks standard name is default.conf
Must NOT be Running Code::Blocks when renaming or deleting config file.

My intial global variable was set at: wx base = c:\wxWidgets-2.8.12. I only included the 'include' directory as one of my many steps to troubleshoot the link /LIBPATH error. I figured out why I'm getting the link /LIBPATH error. It has to do with my project build option linker-libraries setting that are being entered automatically by C::B. I'm using a unicode build of wxWigets. C::B had the link libraries setting like so:

link libraries
are should be
wxmswd wxmsw28ud
wxbased wxbase28ud
etc.. etc..

I am now getting alot of:
TutorialMain.obj||error LNK2019: unresolved external symbol "void __cdecl wxOnAssert(char const *,int,char const *,char const *,char const *)" (?wxOnAssert@@YAXPBDH000@Z) referenced in function "public: __thiscall wxStringBase::wxStringBase(class wxStringBase const &)" (??0wxStringBase@@QAE@ABV0@@Z)|
errors. I'm going to follow your suggestion and rename my default.conf file and see if I can reconfigure c::b.

Thanks for your help Tim.

SUCCESS!! Finally.

For whatever reason, on my first attempt to set the wx global variable, C::B would not accept my location for wxwidgets (which was valid). And the wizard would prompt me to enter it again. In both cases I used the browse button in the project wizard to set the variable. On the second attempt in would accept it, but would put the literal directory string in the wizards wx variable text block, as opposed to referring to $(#wx).

And for some reason with the literal directory set for the wx variable, the project wizard would not display the configuration page that allows for the setting of the wxwidgets build configuration e.g. static, monolithic, unicode, etc. Once I had the ability to make those setting everthing worked. After changing the literal directory location with the $(#wx) variable string.

Thank you Tim.S for all your assistance.
