C::B svn 11029 compiles but not 11030

[gd_on]

My last svn compilation was OK (svn 11029) but when I tried to update to 11033 I had problems. After some tests, it looks that the problem comes with svn 11030.
The problem appears when compiling codeblocks.exe.

I'm on Windows 10. I compile with tdm mingw 4.9.2 (32 bits and also some tests in 64 bits). I use wxwidgets 2.8.12 compiled with the same compiler.
Apparently, something has changed and need wxString_wxPG_LABEL which was not used (?) before.

Is it a problem with my compiler version (I don't use tdm 5.1 because I have problems with gfortran 5.1) , my wxwidgets version ?
I reverted to 11029, recompiled totally to be sure, and it's OK with this version

Is this error happening after a full rebuild?

[Miguel Gimenez]

Yes, and also happens with TDM5.1

Does nm work on windows? Can you run it on the wxpropgrid dll?
See the output for me on linux:

Code Select Expand


> nm libwxpropgrid.so | grep LABEL
00000000002c3e2c B wxEVT_PG_LABEL_EDIT_BEGIN
00000000002c3e28 B wxEVT_PG_LABEL_EDIT_ENDING
00000000002c46b0 B wxString_wxPG_LABEL


If nm doesn't work can you try dependency walker tool and see if there is this symbol in dll?

[Miguel Gimenez]

It appears with a leading underscore

C:\trunk\src\devel>nm wxpropgrid.dll | grep LABEL

6e4e651c B _wxString_wxPG_LABEL

Possible patch that needs tested on Linux and Windows using wxWidgets 2.8.12.

wxpropgrid: Backported "wxPGProperty::sm_wxPG_LABEL" from wxWidgets git master.

Too tired to test; it fixed the link error on Windows.

NOTE: I am a good C Programmer;but, still learning C++. So, needs checked for stupid C++ mistakes.

Deleted patch file.

I was away yesterday so could not answer directly, but I agree with answers given by mgimenez.

Gives redefinition error:

[oBFusCATed]

Should be fixed in trunk/master.

[stahta01]

Should be fixed in trunk/master.

Code::Blocks core project built using MinGW64 gcc 5.3.0 and wxWidgets 2.8.12.

It ran, but, I did no testing just openned and closed code::blocks.

It looks OK, at least on Windows.
Thanks all
