Help / Re: Why does the code editor window close after saving a file?
« Last post by Miguel Gimenez on April 17, 2026, 09:25:55 am »This issue has not been reported elsewhere before, and it is very strange. May the destination folder (or file) be write-protected?

Help / Code editor window closing after saving files (related to very large projects)
« Last post by Stratelier on April 17, 2026, 03:59:17 am »I'm trying this IDE for the first time (latest version, 25.03), but already I've hit a major problem: every time I save any code file I'm working on, the save is successful but then the editor window closes itself. Not just the tab for the file saved, but the entire code editor window (all tabs) -- see attachment for an example.
Is this adjustable? I've sifted through the settings once and didn't find anything obviously relevant. I also (temporarily) disabled ALL of the extensions, which confirmed only that it isn't extension related (the underlying issue still happens).
Sure, it is technically a "minor" issue but this is such an obvious UX breaker I simply can not negotiate. If it's a bug then fine, but in the meantime I am already continuing my search for a (different) code editor.

Using Code::Blocks / Re: OpenCV error in code::blocks
« Last post by stahta01 on April 14, 2026, 11:32:20 pm »Rereading your message implies that the error is during the wizard.
Right click on the wizard and you can edit it.
You need to state what are the names and path to the DLLs and DDL import libs:
I edited the wizard for me by removing [_T("\\libopencv_core") +].
But that was because the import library did not have the version in it.

Code
local test_release_lib_file = lib_nomacro + _T("\\libopencv_core") + VersionString + _T(".dll.a");
local test_debug_lib_file = lib_nomacro + _T("\\libopencv_core") + VersionString + _T("d.dll.a");

Using Code::Blocks / Re: OpenCV error in code::blocks
« Last post by stahta01 on April 14, 2026, 10:40:47 pm »Something to try is
Project -> Build Settings
Select the project in left hand window
Linker Settings
Then remove the version variable of "CV_VERSION" also remove the "$" sign and braces before and after.
I then got an error I did not understand.

Using Code::Blocks / OpenCV error in code::blocks
« Last post by jhongramaticus on April 14, 2026, 09:49:54 am »I'm trying to use OpenCV (version 4.12.0) in Code::Blocks (version 25.03). When installing OpenCV, I used CMake to generate the libraries in Code::Blocks and Mingw. Once I obtained openCV.cbp, I compiled it in Code::Blocks to generate the libraries. After that, I opened code::blocks<<file<<new<<project<<openCV project<< next<<next<<next<< and I got the following error:
I created the x86<<mingw folder so that cmake would generate the files in that location. Despite searching for help on Stack Overflow and other sites, I found no answers. I renamed the library libopencv_core4120.dll to libopencv_core121d.dll.a and it worked fine until yesterday. Now I've deleted code::blocks and OpenCV, regenerated the libraries, and when I try to use any program that has an OpenCV library, I get the message:
Before attempting to create code using OpenCV's Code::Blocks project, I added it only to Settings <<Compiler <<Linker Settings and the directory to Settings <<Compiler <<Search Directories. I've since removed everything, but I'm still getting the same errors, both when creating a project using OpenCV's code::blocks<<file<<new<<project<<openCV project<< next<<next<<next<< and when creating a regular file just mentioning the OpenCV libraries. Sometimes, even a simple "Hello World" code won't compile because of these OpenCV problems.

the lib path you entered seems invalid, can't find files C:\opencv\build\x86\mingw\lib\libopencv_core121.dll.a or C:\opencv\build\x86\mingw\lib\libopencv_core121d.dll.a I created the x86<<mingw folder so that cmake would generate the files in that location.
