Newbie problem
« on: February 12, 2010, 06:45:52 pm »
Hi all,

  I have a problem, (i'm newbie). I installed WxWidgets 2.8.8, and Code::Blocks 8.02 (from Vector Linux 6 repo), and made the hello example (like in the wiki), but i have compile errors, and i think i have to set something else that i didn't. I made 4 try with WxSmith (Frame Based):

1- WxWidgets Lib / advanced options /use unicode build

I'm sure i made i mistake, but don't understand which is, wrong WxWidgets install? wrong Code::Blocks install? wrong settings?

Hope someone knows it.

Thanks, Bye all

Do you have wxWidgets development package installed ?

I don't know how it is called on vector linux, but should be something like libwx*-dev or wxgtk-devel .

Hello Jens,

  Thanks for the reply. Anyway i think i din't understand something: the error in my post happen when i create a "Release" configuration, but if i create a "Debug" configuration, with standard WxWidgets library set in the WxSmith dialog at project creation, it works, and  compile without errors, instead if i create a "Debug" configuration, with dynamic WxWidgets library it gives the same errors. Is there any difference between "Debug" and "Release" configuration related to the Wx library link?
Anyway i think i'll install WxWidgets 2.8.10 full from their site, cause apart the difference regarding Debug & Release configuration (that i don't know), i think that the library from VectorLinux repo should be incomplete (at least lookin inside the archive).

Thanks Again, Regards

I know this is an old thread, but I recently had a similar problem, and I stumbled upon this thread in looking for a solution.  I ended up having to figure it out myself, so I thought I'd post the resolution here.  I'm using code::blocks 8.02 on Ubuntu 10.04.  When I started a new wxWidgets project and checked the "Use Advanced Options" box during initial setup, the skeleton code would fail to compile, giving "./wx_pch.h:14:23: error: wx/wxprec.h: No such file or directory".  If I unchecked the Advanced Option, it worked.  If found that under "Project->Build options->Compiler settings->Other options", `wx-config --cflags` was listed when it compiled, but it was not listed when it didn't compile.  Likewise, `wx-config --libs` needed to be present under "Project->Build options->Linker settings->Other linker options" for it to link properly.

If you use advanced options, there is a difference between releas and debug target, so the wx-config lines are on target and not on project level.

The second point is, that you should know what you do, if you use advanced options: be sure you have an appropriate wx installation, e.g. non-unicode (ansi) and probably static build (no dynamic libs), otherwise the build fails (of course).
