Development / Re: Change to C++17?

I think plain c++20 should be okay as we do not use any gnu specific extensions.

Regarding squirrel warnings, looks like it is fixed upstream by casting : https://github.com/albertodemichelis/squirrel/commit/6ad6f6427157757c4431907dde0a1e5712a5cf67

Should we use gnu++20 or plain c++20?

I use wx2.3.8 and wx3.3.3 for CodeBlocks (all compiled at c++20) every day.

Hi Miguel,

I've been using c++20 for a long time without any issues in my custom branch's  autotools build on ubuntu. I think we can upgrade to c++20 directly.

For autotools, following change should be sufficient : https://github.com/josephch/codeblocks/commit/c56d5feaf0ce0c5d511263d1fba29e3713af68e2

Just to inform you that with my CodeBlocks_Windows.workspace, and setting my global variable cb_build.cpp_std to gnu++20, codeblocks compiles correctly as far as I have tested. Of course, this does not cover all build methods.

Have you tried to compile the full version with C++17

I have not tried, developers must agree on the change beforehand. Changing the CBP is easy, the problem may come later from autotools.

Errors in Squirrel can be fixed, but it uses tricky memory accesses that may be a headache.

Leap-15.6-64bits, wx-3.2.8;gtk3-u, gc-15.2
'r14003.cbp' ( no 'contrib' )
Here is the compilation log with 'C++17' :

Have you tried to compile the full version with C++17 (Win-xx, Linux-xx) ?
If so, what warnings have you obtained ?

There is an updated version of astyle library (3.6.18) that fixes some issues (see ticket 1643, but it uses the stupid C++17-only std::string_view and we currently are using C++11.

There is also some C++17-only code, like [fallthrough] in clangd_client, generating warnings.

Should we change to C++17?

General (but related to Code::Blocks) / Re: Faild to build C::B with github action with latest wxWidgets 3.3.3

« Last post by Pecan on September 09, 2026, 06:15:20 pm »

This is a reference to what might be another instance of this problem:

When working on builds for Fedora ([url]https://copr.fedorainfracloud.org/coprs/sharkcz/danny/build/10959184/[/url], details are in the builder-live.log files), I have noticed that libtool version 2.6.2 present in Rawhide fails the build of the codesnippets plugin after the tinyxml LIBADD was removed from its Makefile.am in revision 13996. System tinyxml library is used in the builds. I have confirmed that with libtool downgraded to 2.5.4 the build runs OK. AFAICT other plugins still use the LIBADD mechanism. Likely some change in libtool is causing this ...

Maybe something related to this discussion: [url=https://forums.codeblocks.org/index.php/topic,26338.msg179012.html#msg179012]Faild to build C::B with github action with latest wxWidgets 3.3.3[/url]

It is also related to the tinyxml library and the linker issue.

I worked all the way back to svn 13733 and found no changes in the Makefile.am file. So it has to be something that wasn't deleted, but needs to be added.

It's suggested to change Makefile.am for codesnippets to:

libcodesnippets_la_SOURCES = codesnippets.cpp \
       codesnippetstreectrl.cpp \
--- a/src/plugins/contrib/envvars/Makefile.am
+++ b/src/plugins/contrib/envvars/Makefile.am

Can anyone tell me what I need to run to test that this would not screw up anything else on linux or windows.
