code::blocks hangs at startup

[Miguel Gimenez]

Thanks for testing. If this works then I will leave wxsresourcetree as is, because the change would be complex.

Probably works because wxsresourcetree uses cbLoadBitmap(), which calls wxImage::LoadFile() instead of wxBitmap::LoadFile().

@ChrisK , @blauzahn, @Lufex, @cet_ivan, @JorgenBest : would you be able to verify, if with the latest state of the code the problem is also gone on your side ?

[JorgenBest]

The 25-03-2 version that I have still has this problem, but that's the regular version and not a nightly build or so.

I have difficulties installing all kinds of sources. I think I need something that is not yet out and I'm not to trusted with finding the right sources, dependencies and compilation myself. I use Arch Linux as rolling release platform (version 25-03-2), but there are no updates that yet worked to solve this problem. Also on aur nothing is yet more recent available.

So you help me I gladly test something if I can install and reverse it easily on my system.

cb still hangs at startup on arch Linux, cb-trunk build with the distributed wx-3.2.9. In my Makefile, wxSmith plugins are disabled at configure:

Code

  (cd $(build) && \
	  LT_SYS_LIBRARY_PATH=$(WX_PREFIX)/lib \
	  CC=${CC} CXX=${CXX} ../$(trunk)/configure \
	  --enable-debug=yes \
	  --enable-pch=no \
	  --prefix=$(PREFIX) \
	  --with-wx-config=$(WX_PREFIX)/bin/wx-config --with-wx-prefix=$(WX_PREFIX) \
	  --with-contrib-plugins=all,\
         -wxsmith,-wxsmithaui,-wxsmithcontrib,\
         -NassiShneiderman,-codesnippets,-dragscroll)

Console output at startup is:

Please note the assert. I have seen this a few times over the years. I use an out of tree build. The installation directories of cb are pristine and without stale files. I verified this, recompiled, reinstalled but the assert remains.

My wxWidgets has been configured for years this way:

Code

  mkdir -p $(BUILD)
  (cd $(BUILD) && ../$(TRUNK)/configure --prefix=$(WX_PREFIX) --with-cxx=17 --with-gtk --without-libtiff --enable-debug)

Please note: wx installed in /opt/wx requires ld to find it when linking cb:

Code

echo $(WX_PREFIX)/lib >/etc/ld.so.conf.d/wxwidgets.conf
