IsShown - undefined Reference

[CktDesigner]

I'm attempting to upgrade wxWidgets from 3.0.2 to 3.0.4

I compiled and installed the 3.0.4 release, then attempted to re-compile a couple of applications.

Both compiles would not link due to an undefined reference to IsShown(). Here are the errors when trying to compile wxFormBuilder:

The other application uses files generated using wxFormBuilder, but has similar issues:

Since I don't see direct calls to IsShown() in my code (or wxFormBuilder), I'm not sure how to proceed in debugging. Both applications compiled/linked using 3.0.2.

Are there differences between 3.0.2 and 3.0.4 that could cause this?

Thanks!

Here is the command line for the linker (shows the libraries):

g++ -o bin/Debug/OrbInterface obj/Debug/wxFormBuilder_DerivedFiles/OrbInterface.o obj/Debug/wxFormBuilder_DerivedFiles/OrbPanel.o obj/Debug/OrbInterface/OrbConnected.o obj/Debug/OrbInterface/OrbInterfaceApp.o obj/Debug/OrbInterface/OrbInterfaceMain.o -pthread -lwx_gtk3u_xrc-3.0 -lwx_gtk3u_html-3.0 -lwx_gtk3u_qa-3.0 -lwx_gtk3u_adv-3.0 -lwx_gtk3u_core-3.0 -lwx_baseu_xml-3.0 -lwx_baseu_net-3.0 -lwx_baseu-3.0 /lib/libwx_gtk3u_adv-3.0.so

Doing "nm -D on /usr/lib/libwx_gtk3u_adv-3.0", it looks like "IsShown" is in this library??

Did one more test. I created a new wxWidgets project in CodeBlocks, then did a build. Here is the output:

I assume I did something wrong when I compiled/installed wxWidgets 3.0.4.

Suggestions are welcome!

Thanks!

Hi,

Two questions:
1) Where did you install wx3.0.4? Was it configured as a 'local' install with --prefix=$(pwd), or to prefix $SomewhereElse, or did you let it install to the default /usr/local/? And where is/was the wx3.0.2 build? I'm asking in case you have a linking conflict between two installed versions.

2) How are you trying to build? From within C::B, or in a terminal? If the former, look very carefully at your compiler and linker settings to make sure they are pointing at the same wx. If the latter, or indeed anyway, what is the relevant output of doing, in a terminal:
wx-config --version
wx-config --cxxflags
wx-config --libs

Oh, and I assume you are using the second two wx-config calls when you try to build, rather than pasting in their output by hand...

Regards,

David

Thanks for your response... I am building on CentOS 7 via a normal terminal window. Here is the output of the commands you requested:

[hepler@centos7 gtk-build]$ wx-config --version
3.0.4
[hepler@centos7 gtk-build]$ wx-config --cxxflags
-I/usr/lib/wx/include/gtk3-unicode-3.0 -I/usr/include/wx-3.0 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXGTK__ -pthread

-pthread -lwx_gtk3u_xrc-3.0 -lwx_gtk3u_html-3.0 -lwx_gtk3u_qa-3.0 -lwx_gtk3u_adv-3.0 -lwx_gtk3u_core-3.0 -lwx_baseu_xml-3.0 -lwx_baseu_net-3.0 -lwx_baseu-3.0
[hepler@centos7 gtk-build]$


I configured using:

../configure --with-gtk=3 --prefix=/usr --with-opengl --enable-mediactrl

After the configure, I performed make, then as super-user, performed make install and ldconfig

After trying to recompile a couple of applications (wxformbuilder and one of my own), I created a new wxwidgets project in C::B and simply compiled (no additions or changes) and got:

The linker option within C::B is set to call "wx-config --libs"

Thanks for your assistance...

Oops... Looks like the wxwidgets build put the results in /usr/lib (per the --prefix configuration) while C::B and the wxformbuilder must have been looking in /usr/lib64

I copied all of the /usr/lib/libwx_gtk3... files to /usr/lib64 and things seem to work!

Thanks!
