Development / Re: build bot in the github, I see one nice project
« Last post by ollydbg on September 24, 2024, 03:46:57 pm »I want to remove the hack of the dll export hack in building wxsmith plugin.
So, I remove the hack above.
Now, I see the build error.
It looks like the dll export declaration is not defined.
But when I checked the build log, I see that:
You see, when building every plugin, the "-DDLL_EXPORT -DPIC" is defined.
But my question is: Where is the "DLL_EXPORT" get defined? I search all the C::B code git repo, and I can't find one.
When I check the cbp files, I see there is no "DLL_EXPORT" defined, instead, in the cbp file, another macro named "BUILDING_PLUGIN", this is core point, because in the
include\cbplugin.h, note this file is included in every cpp file when you need to build a plugin.
So, I think we need to solve this issue.
I even checked the configure.ac file or Makefile.am file, I don't find the DLL_EXPORT definition.
Is this value a predefined string?
Code
# Workaround from msys2: error: definition of static data member 'wxsArrayStringEditorDlg::sm_eventTable' of dllimport'd class
# grep -rl "PLUGIN_EXPORT " src/plugins/contrib/wxSmith | xargs -i sed -i "s/PLUGIN_EXPORT //g" {}
