Question

I installed wxWidgets-2.8.10 following instructions from this page:
http://wiki.wxwidgets.org/Compiling_and_getting_started

Libraries directory:

alex@alex-linux:/usr/local/lib$ ls | grep wx
libwx_base-2.8.a
libwx_base_net-2.8.a
libwx_base_xml-2.8.a
libwx_gtk2_adv-2.8.a
libwx_gtk2_aui-2.8.a
libwx_gtk2_core-2.8.a
libwx_gtk2_html-2.8.a
libwx_gtk2_qa-2.8.a
libwx_gtk2_richtext-2.8.a
libwx_gtk2_xrc-2.8.a
libwxtiff-2.8.a
wx

Then I created file widgetTest.cpp and filled it with this code:
http://www.wxwidgets.org/docs/tutorials/hworld.txt

Trying to build it, I have a lot of linker errors:

alex@alex-linux:~$ cd /home/alex/Tmp
alex@alex-linux:~/Tmp$ g++ `wx-config --cppflags` `wx-config --libs` widgetTest.cpp
/tmp/ccnPCAw5.o: In function `wxCreateApp()':

widgetTest.cpp:(.text._ZN20wxThreadHelperThreadD0Ev[wxThreadHelperThread::~wxThreadHelperThread()]+0x16): undefined reference to `wxThread::~wxThread()'
collect2: ld returned 1 exit status

Additional information:

What is wrong?

Answer 1

Does this help?

g++ `wx-config --cppflags` widgetTest.cpp `wx-config --libs`

Sometimes putting the libraries after the sources is required.
