cannot find -1C:\wxWidgets-3.1.3

[HairyHugh]

Hi
I am following the PB's Guide to starting with xwWidgets on Microsoft Windows with MinGW and Code::Blocks. I am using Windows10, on a 64 bit system. I have set WXWIN correctly (CMD.exe and cd %WXWIN" works OK).
I am using wxWidgets-3.1.3, Code::Blocks 20.03 and C:\mingw-w64\i686-8.1.0-posix-sjlj-rt_v6-rev0
I have gone through the whole process and successfully run the wxWidgets minimal sample prior to using Code:Blocks.
However when trying to compile and run the test app in Code::Blocks I get an error:
ld.exe cannot find -1C:\wxWidgets. I have double checked all of the options I can see and they all look OK. Also searched for this error message but not found it anywhere.
I assume I am missing some directive but am unable to find it.

You are using the digit '1' and it is an invalid option. This option should be added automatically by C::B, so you must be messing something in the project options.

Please post a full rebuild log:

Hi Miguel
Thanks for response. Not sure where the 1 comes from, I cannot see it anywhere in options. Full build log below

C::B uses a lower case 'L', probably you mistook it for a '1' when writing the subject.
The -l option specifies a file to link, you are supplying a folder instead. Look for C:\wxWidgets3.1.3 in Linker settings -> Link libraries and remove it.

[HairyHugh]

I have looked under projects\build options and setting\compiler and cannot find it anywhere there.

[stahta01]

Did you check the linker settings tab?

Both "Link Libraries" and "other linker options".

[Miguel Gimenez]

Each target has his own set of options, you must look in both Debug and Test nodes.

You can also attach the CBP file here, or open it with a text editor and search for C:\wxWidgets-3.1.3

[HairyHugh]

Hi Tim,
Not in either under debug or release.
Miguel
Did you mean to add a link for the CBP file or am I not understanding you

[Miguel Gimenez]

I mean attach the Test.CBP file (only) to your reply, using the "Attachments and other options" below. The extensions are restricted, so you must change it (from CBP to TXT, for example) or create a ZIP.

[HairyHugh]

OK I am with you now, file attached

[Miguel Gimenez]

It is not in the CBP, so it must be in the global compiler settings:

Settings  -> Compiler settings -> Linker settings -> Link libraries

Possibly it is disguised as $(#wx)

EDIT: select compiler "mingw-w64-i686-810-posix-sjlj" if it is not the default

[HairyHugh]

Many thanks, somehow I managed to get $(#wx.BASE) incorporated.
Working now, so now to build a real app
