[SOLVED] wxWidgets

ZoLA · 2015-08-24 16:14:17

HI guys, i have installed wxwidgets using pacman 'sudo pacman -S wxgtk' and if i put simple program with wxPuts() just to print text using wx function i got to much errors in compile time. I try to compile with this: g++ main.cpp `wx-config --cxxflags --libs` -o main
wx-config --version : 3.0.2

Please, post the code you are trying to compile and the full compilation output with the error messages.

It compiled fine on my desktop, but it failed on my laptop with a similar error: wx-config tells the compiler to link the following libraries:

$ wx-config --libs
-pthread   -lwx_gtk2u_xrc-3.0 -lwx_gtk2u_webview-3.0 -lwx_gtk2u_html-3.0 -lwx_gtk2u_qa-3.0 -lwx_gtk2u_adv-3.0 -lwx_gtk2u_core-3.0 -lwx_baseu_xml-3.0 -lwx_baseu_net-3.0 -lwx_baseu-3.0

now the problem is that libwx_gtk2u_webview-3.0.so is linked to libwebkitgtk-1.0.so.0 which is provided by the package webkitgtk2. So, you have two options:

Use wx-config and Install the package webkitgtk2

Don't use wx-config and manually specify the libraries to link to, for example

 g++ main.cpp -o main -I/usr/lib/wx/include/gtk2-unicode-3.0 -I/usr/include/wx-3.0 -DWXUSINGDLL -D__WXGTK__ -pthread -lwx_gtk2u_core-3.0  -lwx_baseu_xml-3.0 -lwx_baseu_net-3.0 -lwx_baseu-3.0

--edit: typo

Well, 'tons of errors' is not helpful... they are the same errors you get before? If not post them. Which of the two options you used? Is your system fully updated? What is the output of the following commands?

$ uname -a
$ pacman -Qi wxgtk webkitgtk2 gtk2
$ wx-config --cxxflags --libs

However, let's try first using the option one: according to ldd, these are all the packages you need to install in order to compile the program using wx-config, make sure you have all of them installed:

$ ldd main | awk '{print $3}' | pacman -Qqo - | sort --unique
atk
bzip2
cairo
enchant
expat
fontconfig
freetype2
gcc-libs
gdk-pixbuf2
glib2
glibc
graphite
gst-plugins-base-libs
gstreamer
gtk2
harfbuzz
harfbuzz-icu
icu

libffi

From your last compilation log, it seems that the most of what you think are errors are just warnings and can be safely ignored (there is also a bug report for that, see https://bbs.archlinux.org/viewtopic.php?id=198385. It has been fixed recently so we probably have to wait until gcc 5.3 is out). The only error appears to be the following:

/usr/bin/ld: cannot find -lwx_gtk2u_wx-3.0
collect2: error: ld returned 1 exit status

I cannot find libwx_gtk2u_wx-3.0.so in any official package

$ pkgfile  /usr/lib/libwx_gtk2u_wx-3.0.so
$

and I don't understand why g++ tells ld to link that library since it is not in the options passed by wx-config... The output of wx-config is taken before or after you installed webkitgtk2? Can you please post the output of the following commad?

#  ldconfig -p | grep wx_gtk2u_

PS: Also, since you installed webkitgtk2 I assume you used only the first option, have you tried also the second option using the command I posted?

Everything seems alright there... Can you post the output of the compilation when using the --verbose options?

g++ --verbose main.cpp `wx-config --cxxflags --libs` -o main

Yeha, that looks good... maybe there was a typo in the command you used previously.

Indeed (read the link I posted in post #8), but as I previously said you can safely ignore them...
