Title: linux and pch
Post by: frithjofh on December 20, 2007, 09:06:46 pm
hi everybody,

i'm a bit ashamed, but i surrender: I'm using c::b 4707 on a suse 10.3 x86_64 installation and i can set up and compile and run a simple wxwidgets project generated with the wizard. but when i generate the same project, all settings identical, only changing to use precompiled headers i get the error:

./wx_pch.h         line 14      error: wx/wxprec.h: file not found

the file does exist, it is in a directory supposedly included by the wx-config --cflags

i searched through the forum and found many related topics, but i don't seem to be able to mine the necessary information from it  :(

please help me somebody

regards

With regards, Morten.

hi and thanks for the reply,

allready felt a bit deserted ...  :D

the output of wx-config --cflags is this:

-I/usr/lib64/wx/include/gtk2-unicode-release-2.8 -I/usr/include/wx-2.8 -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D__WXGTK__ -pthread

so far a standard wxwidgets project without pch enabled works fine as stated above...

greetings from asturias y feliz navidad

The file "/usr/include/wx-2.8/wx/wxprec.h" definitely exists?

Can you post the full command-line from the build log?

You might have to turn full command line logging on in "Settings -> Compiler and debugger ... -> Global compiler settings -> Other settings -> Compiler logging".
"Other setings" is the rightmost tab in "Global compiler settings".

hi everybody,

i have to apologize: aparently the problem was not the pch function, but the checkbox advanced options in the  scripted wizard. i'm working under suse x86_64 on an amd 64 x2 4200 with the revision 4716. i made a test suite of the posible combinations and the variant with the pch enabled definitivly works same as with pch disabled... :oops: :oops: :oops: really ashamed. i opened a project from my windows box to try how it might be working on linux only and it must have happend somewhere around then, just slipped my mind...

still strange: it seems that this advanced options checkbox does only harm on linux even if i don't choose any suboption of that part of the wizzard (there are: use shared library and use unicode build if i remember ...). the project then just does not compile. the only differences in the projects build options are that instead of having the sole `wx-config --cflags` and `wx-config --libs` under its correct place in the respective tabs of the project, they are moved to the build targets and somewhat extended: `wx-config --version=2.8 --static=yes --unicode=yes --debug=yes --cflags` and `wx-config --version=2.8 --static=yes --unicode=yes --debug=yes --libs` in the case of debug target and build target respectively.

so, sorry again for all the panic ... and: whats wrong with that advanced options in the wizzard under linux ????

regards

Have you run the second "wx-config "-line on console ?
I think you don't have a statically linked debug versin of wxWidgets and then the appropriate directory to include is not on disk.
Here is what happened when I run it in a console ( I have the debug-version installed, but to get a statically linked version I would have to compile it myself, but statically linked wx-Widgets is quite large):
Code
jens@debian-inspiron:~$ wx-config --version=2.8 --static=yes --unicode=yes --debug=yes --cflags

  Warning: No config found to match: /usr/bin/wx-config --version=2.8 --static=yes --unicode=yes --debug=yes --cflags
           in /usr/lib/wx/config
  If you require this configuration, please install the desired
  library build.  If this is part of an automated configuration
  test and no other errors occur, you may safely ignore it.
  You may use wx-config --list to see all configs available in
  the default prefix.

As Jens have posted the solution, I'm not repeating it.

Unfortunately wx wizard doesn't check for missing configuration as it does on Windows. There are some reasons for not doing so. That was the reason of not checking the Advanced option by default in the wizard. When you are using the Advanced option on Linux or Mac, you must make sure that the configuration you want to use exists on your system. :)
