The https://sourceforge.net/p/codeblocks/code/HEAD/tree/trunk/src/CodeBlocks_wx31_64.workspace (https://sourceforge.net/p/codeblocks/code/HEAD/tree/trunk/src/CodeBlocks_wx31_64.workspace) file has the CodeBlocks_wx31_64.cbp as the first entry:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<CodeBlocks_workspace_file>
<Workspace title="CodeBlocks Workspace wx3.1.x (64 bit)">
<Project filename="CodeBlocks_wx31_64.cbp" active="1" />
<Project filename="tools/Addr2LineUI/Addr2LineUI_wx31_64.cbp" />
Probably you are looking at the dependency of the last project:
<Project filename="plugins/contrib/ToolsPlus/ToolsPlus_wx31.cbp">
<Depends filename="CodeBlocks_wx31.cbp" />
</Project>
</Workspace>
</CodeBlocks_workspace_file>
Here is mine :
<Project filename="plugins/contrib/symtab/symtab_wx31_64.cbp" />
<Project filename="plugins/contrib/ThreadSearch/ThreadSearch_wx31_64.cbp">
<Depends filename="plugins/contrib/wxContribItems/wxContribItems_wx31_64.cbp" />
</Project>
<Project filename="plugins/contrib/ToolsPlus/ToolsPlus_wx31_64.cbp" />
<Project filename="CodeBlocks_wx31_64.cbp" />
</Workspace>
</CodeBlocks_workspace_file>
I don't know where this anomaly comes from, I just checked with 'cb-12814' : it is correct.
