Question

I built wxWidgets on Linux using this command:

../configure –enable-shared –disable-debug

It see results of this build:

/usr/local/lib/wx/config/gtk2-ansi-release-2.8

/usr/local/lib/wx/include/gtk2-ansi-release-2.8/wx/setup.h

wx-config output:

alex@alex-linux:~$ wx-config --list
    Default config is gtk2-ansi-release-2.8
  Default config will be used for output
  Alternate matches:
    gtk2-ansi-debug-2.8
    gtk2-ansi-debug-static-2.8
    gtk2-ansi-release-static-2.8
alex@alex-linux:~$ wx-config --cppflags --release
2.8
-I/usr/local/lib/wx/include/gtk2-ansi-release-2.8 -I/usr/local/include/wx-2.8 -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D__WXGTK__
alex@alex-linux:~$ wx-config --libs --release
2.8
-L/usr/local/lib -pthread   -lwx_gtk2_richtext-2.8 -lwx_gtk2_aui-2.8 -lwx_gtk2_xrc-2.8 -lwx_gtk2_qa-2.8 -lwx_gtk2_html-2.8 -lwx_gtk2_adv-2.8 -lwx_gtk2_core-2.8 -lwx_base_xml-2.8 -lwx_base_net-2.8 -lwx_base-2.8 

Now I am trying to build Hello wxWidgets program with Release version:

g++ -I/usr/local/lib/wx/include/gtk2-ansi-release-2.8 -I/usr/local/include/wx-2.8 -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D__WXGTK__ hello.cpp -o hello -L/usr/local/lib -pthread   -lwx_gtk2_richtext-2.8 -lwx_gtk2_aui-2.8 -lwx_gtk2_xrc-2.8 -lwx_gtk2_qa-2.8 -lwx_gtk2_html-2.8 -lwx_gtk2_adv-2.8 -lwx_gtk2_core-2.8 -lwx_base_xml-2.8 -lwx_base_net-2.8 -lwx_base-2.8

It compiles and runs successfully on my computer. Program dependencies:

ldd hello
 linux-gate.so.1 =>  (0x006ef000)
 libwx_gtk2_richtext-2.8.so.0 => /usr/local/lib/libwx_gtk2_richtext-2.8.so.0 (0x00253000)

 libwx_base-2.8.so.0 => /usr/local/lib/libwx_base-2.8.so.0 (0x006f0000)
    ...

Now I want to execute this program on another computer without wxWidgets installed. I copy the program and all shared libraries to another computer:

hello                        libwx_gtk2_core-2.8.so
libwx_base-2.8.so            libwx_gtk2_core-2.8.so.0
libwx_base-2.8.so.0          libwx_gtk2_core-2.8.so.0.6.0
libwx_base-2.8.so.0.6.0      libwx_gtk2_html-2.8.so
libwx_base_net-2.8.so        libwx_gtk2_html-2.8.so.0
libwx_base_net-2.8.so.0      libwx_gtk2_html-2.8.so.0.6.0
libwx_base_net-2.8.so.0.6.0  libwx_gtk2_qa-2.8.so
libwx_base_xml-2.8.so        libwx_gtk2_qa-2.8.so.0
libwx_base_xml-2.8.so.0      libwx_gtk2_qa-2.8.so.0.6.0
libwx_base_xml-2.8.so.0.6.0  libwx_gtk2_richtext-2.8.so
libwx_gtk2_adv-2.8.so        libwx_gtk2_richtext-2.8.so.0
libwx_gtk2_adv-2.8.so.0      libwx_gtk2_richtext-2.8.so.0.6.0
libwx_gtk2_adv-2.8.so.0.6.0  libwx_gtk2_xrc-2.8.so
libwx_gtk2_aui-2.8.so        libwx_gtk2_xrc-2.8.so.0
libwx_gtk2_aui-2.8.so.0      libwx_gtk2_xrc-2.8.so.0.6.0
libwx_gtk2_aui-2.8.so.0.6.0

And run it:
LD_LIBRARY_PATH=. ./hello

Result:

Fatal Error: Mismatch between the program and library build versions detected.
The library used 2.8 (debug,ANSI,compiler with C++ ABI 1002,wx containers,compatible with 2.6),
and your program used 2.8 (no debug,ANSI,compiler with C++ ABI 1002,wx containers,compatible with 2.6).
./run.sh: line 1:  1810 Aborted                 LD_LIBRARY_PATH=. ./hello

What is wrong?

Answer 1

You may need to check if none of your headers declares DEBUG macro this or that way. I ran into this problem once.

Apart from that, it may be better to perform static linking instead.
