wxWidgets Discussion Forum

Hello,

i use CodeBlocks 17.12 @ win10 and MinGW - currently with wx 3.1.2. Now i want to compile with wx 3.1.3.

What i did:
I downloaded and unpacked the 7z-file, so that i have two wxWidgets-folders now: "wxWidgets-3.1.2" and "wxWidgets-3.1.3".
I changed all haeader-, library-, and resource-search-paths to the new folder.
I tried to rebuild all.

The result is: It seems, that i forgot to change a parameter or a path. Any idea wht this might be?

Thank you,
Frank

There is a "master" copy of setup.h in <wxdir>/include/wx/msw/

If you build wxWidgets with a specific configuration, this will be copied to e.g. <wxdir>/lib/vc_lib/mswu/wx/
(The parts "vc_lib" and "mswu" are compiler/config specific).

This path must also be added to your include paths.

Okay, but i'm a little bit confused now.

I added <wxDir>/include/wx/msw/ to the incluse-search-paths, but shurely this is not what you ment.
The problem occurs at the line... ...but there is no /wx-subfolder in <wxDir>/include/wx/msw/

I also tried to copy <wxDir>/include/wx/msw/steup.h to <wxDir>/include/wx/setup.h manually. Doing this, the compiler reports several of the following errors: Was it the wrong file, that i copied?

Thank you,
Frank

Oh, i see that the dde-error occurs in wrong wxDir. I'll try to find, what i forgot...

Do not copy setup.h anywhere (unless you are using GIT version). The setup.h in the build-specific folder gets created by the wxWidgets build process or is available with the pre-built binaries (in a file such as e.g. wxMSW-3.1.3_gcc730_Dev.7z).

Did you actually build the wxWidgets libraries after switching to 3.1.3? If yes, with command line(s) did you use?

I cleaned up everything and restarted it. I also found the missing binaries wxMSW-3.1.3_gcc730_Dev.7z etc.

After unpacking everything, i had several linker-errors. When i was looking for the reason, i found out, that .a-files in the wx 3.1.2-setup are located in <wxDir>/lib/gcc_lib, but wxMSW-3.1.3_gcc730_Dev.7z extacts them into the dll-subfolder <wxDir>/lib/gcc730_dll.

In order to keep the folder-structure the same as wx 3.1.2 i created the folder gcc_lib manually and moved all the .a-files. This was mostly succesfully, but obviously one .a-file is missing in wxMSW-3.1.3_gcc730_Dev.7z: libwxmsw31u.a is not contained in the archive.

I don't know, where to find it or how to build it myself (tried to look for a source, but i could not find it). Any idea what to do?

Thanks for your help,
Frank

No, i never did it myself. I just downloded the binaries (see post before).

Your Code::Blocks project seems to be setup for static (gcc_lib = static, gcc_dll = dynamic) monolithic (libwxmsw31u.a) build. The prebuilt binaries are available only as dynamic multilib builds.

If you are for some reason unfamiliar with the terminology used above I recommend reading the basic wxWidgets install guide:
https://docs.wxwidgets.org/trunk/plat_msw_install.html

I already tried to change this for a short while, but i could not find the correct flags and as i was not shure if this is the reason, i've stopped it.

Currently i do some other things. I'll try later it again...

I'll mark this thread as solved if i'm successfull. Otherwise i'll continue it probably.

Thank you so far.

There are build instructions for MinGW in <wxdir>/docs/msw/install.md

And here are some extensive instructions for CB/MinGW: viewtopic.php?f=19&t=46125

Hello,

i've red a bit in your links, but for the moment, this is too complicated for me. I've not enough time to learn all of this - not at least because I'm not a native english-speaker.

I've a provisoric solution, that i can use for my application until i find the time to lean this...


Thank you anyway....

Best,
Frank

Hi,
What language do you speak?
Maybe there is an instruction about C::B in your native tongue already exists?

Thank you.

I'm from germany.

I think, my' problem' is not C::B. It's almost the opposite: I never worked without IDE. I never wrote a makefile etc. So, i don't know how all of this is working together. Years ago i downloaded an old wxDevC++-setup as a package, that worked immideately after installing. This i used for some windows-experience (i lerned c-basics in 1990th (ANSI-standard) - but also that time i used an IDE. Last year i've changed to C::B and wx312 and i'm quiet happy that it works, but i still did not comile wx myself.
Also some years ago, i was intersted in if i can do some graphic-things, but never would have expected to write a complete application on my own, but this is what i somehow did step by step. So this is the point, where i am: having a working application that i use myself, to produce live-visual-arts, but no experience in all this backgrounds...
