Question

OS : windows 10 64 bit
IDE : codeblocks 17.12
Compiler : gcc 7.3
with
wxWidget 3.1.2
i build wxWidget 3.1.2 according to the official guide without changing any defaults
make -f makefile.gcc (make v4.2)
i am using codeblocks wxwidget start script 3.1.X
i have choosen correct option according to the wxWidget build
(Monolithic unicode and debug)
The codeblock generated sample problem is not linking properly
( gives build fail with 0 error 0 warning )

This post assumes you have compiled wxWidgets 3.1.3 and are successful in compiling the executable samples via make and makefile.gcc that is included and are using gcc.
It also assumes you have already applied your environment vars in windows, applied your compiler flags wx-config --cxxflags and linker flag wx-config --libs.
It seems everyone else has dugout the makefile library order and has fixed it inside of codeblocks. I wanted to build small all in one apps so I decided on a MONOLITHIC with SHARED=0 UNICODE build.
It seems the easiest fix is thus.
CodeBlocks arranges the linker library order in a different order than the makefile does and jams up the linker, in my case varying from "theme" something or other to scrollbar issues.
So the quickest work around I've found is to delete all the entries in the codeblocks build options lists and enter only into the "Other Linker Options" for Debug and Release and this does work.
So from the console listing the makefile shows copy those linker settings in the order that makefile settings list. So until someone makes a header fixup entry for something higher than 2.8.8 there is this cumbersome workaround.
In my case the working order is as follows:
-mwindows
-lwxmsw31ud
-lwxmsw31ud_gl
-lwxscintillad
-lwxtiffd
-lwxjpegd
-lwxpngd
-lwxzlibd
-lwxregexud
-lwxexpatd
-lkernel32
-luser32
-lgdi32
-lcomdlg32
-lwinspool
-lwinmm
-lshell32
-lshlwapi
-lcomctl32
-lole32
-loleaut32
-luuid
-lrpcrt4
-ladvapi32
-lversion
-lwsock32
-lwininet
-loleacc
-luxtheme
In Release it is the same less the "d" which designates the debug file i.e.:
-lwxmsw31u_gl instead of -lwxmsw31ud_gl,
-lwxtiff in place of -lwxtiffd etc...
