codeblocks cbp projects for wx samples
ollydbg:
Hi, I have some friends who are willing to learn wx by wxWidgets' samples.
I can ask them to use Code::Blocks, while, I think the best way to learn is using wx samples from the official wx git repo (This is not only for beginner, also for testing some wx features):
https://github.com/wxWidgets/wxWidgets/tree/master/samples
My idea is we can supply some C::B cbp files for the samples, I see tim has some contribution:
stahta01/msys2_wxwidgets_cb_projects: CB wxWidgets projects using msys2
This repo contains about 10 samples, but not the full wx samples.
I think either using msys2's pre-build library or self build wx library is OK, so are there any suggestions?
Thanks.
EDIT
I found an old reop which is also by tim
stahta01/cb_projects_for_wxWidgets: Code::Blocks projects for building wxWidgets sample code
It was several years ago, and it use the wx-config.exe.
EDIT2
It looks like wx has cmake support, see this document: wxWidgets: CMake Overview
So, maybe we can use official cmake to generate the codeblocks cbp for each samples?
EDIT3
As 2022-09-17, I create a git repo: asmwarrior/cb_projects_for_wxWidgets: Code::Blocks projects for building wxWidgets sample code, which supples Code::Blocks project files(cbp) for each wx sample (wxWidgets 3.2.1), and with the help of wx-config-msys2.exe (from eranif/wx-config-msys2: wx-config tool for MSYS2 based installation of wxWidgets using the mingw64 repository), it can build wx samples under Code::Blocks and link to the prebuild wx library(wxWidgets 3.2) in msys2.
EDIT4
As 2022-10-09
You can tweak the wx-config variable in your C::B, which can use either the wx library supplied by msys2, or you can using the wx library built by yourself by the "makefile.gcc", see this reply for details.

I spent about one hour trying that; but, I gave up the cmake support files needed was too old in the MSys2 cmake I had.
I might try again; but, right now I am working on building MINGW64 GCC variants and failing.
I do think it is a best long term way to proceed; but, I need to learn the new wxWidgets cmake way and find the correct cmake support files.

--- Quote ---Recommendations
While CMake in wxWidgets aims to support most generators available in CMake the following generators are recommended:
Windows: Visual Studio (any supported version)
macOS: Xcode
Linux: Ninja or Makefiles
CMake 3.10 or newer is recommended. The minimum version required is 2.8.12.

I was not using one of the recommended way; I might try Ninja on my next attempt.

Last time i checked (2 or 3 months ago) the CMake way produced a quite ugly result regarding the samples, at least using Visual Studio and Ninja, every sample got placed into one common directory.

Hi, thanks for the time and help.
I would like to find a simple way, here is my try steps:
I try to create a cbp file which use the makefile.gcc under the sample/minimal folder.
I add the line
--- Code: ---makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=1 VENDOR=cb
--- End code ---
Because I built wx library with the command:
--- Code: ---mingw32-make -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=1 VENDOR=cb
--- End code ---
Now, I have a "all" build target of the cbp file.
When I click the "build" button, I got this:
--- Code: ----------------- Build: all in minimal (compiler: GNU GCC Compiler)---------------
[100.0%] Checking if target is up-to-date: mingw32-make.exe -q -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=1 VENDOR=cb all
Running command: mingw32-make.exe -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=1 VENDOR=cb all

--- End code ---
The Chinese text means "access deny".
When I look at the makefile.gcc, I see this line:
--- Code: ---$(OBJS):
-if not exist $(OBJS) mkdir $(OBJS)
--- End code ---
This means the makefile does not work correctly under C::B, while I see it works correctly under Windows cmd.
Here is the log under Windows CMD
--- Code: ---F:\code\wxWidgets-3.2.1\samples\minimal>mingw32-make -f makefile.gcc SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=1 VENDOR=cb all

--- End code ---
So, it looks like a wrong shell is called? or any solutions?
Thanks.
EDIT: problem solved!
The problem is that I have a path:
--- Code: ---$(TARGET_COMPILER_DIR)../usr/bin
--- End code ---
In the compiler's extra path. I just remove this line, and restart C::B, and it is OK now.
EDIT2:
I think this issue has already mentioned by AndrewCot, because I have put the msys' shell path usr/bin to the mingw64/bin path. Though I can use the sh.exe to call the wx-config script, but this also cause this issue.
ollydbg:
I think creating makefile based cbp is simple. but there is one drawback when using makefile based cbps. :(
That is: code completion plugin/clangd_client plugin doesn't know the include search paths, so no code navigation/code completion.
