Ubuntu 8.0.4 and Code::Blocks problem...

coder89 · Post by **coder89** » Sun Aug 10, 2008 10:56 am

Hello.
I have writting my program in Code::Blocks using the latest wxGTK release. I compiled them and it works. But suddenly when I want to rebuild my program I get few errors like below:

/home/coder89/Pulpit/Programy/CoderCat/globals/../CoderCatMain.h|13|error: wx/menu.h: No such file or directory

/home/coder89/Pulpit/Programy/CoderCat/globals/../CoderCatMain.h|14|error: wx/frame.h: No such file or directory

/home/coder89/Pulpit/Programy/CoderCat/globals/../CoderCatMain.h|15|error: wx/statusbr.h: No such file or directory

/home/coder89/Pulpit/Programy/CoderCat/globals/../include/MyClasses/../../globals/Libraries.h|11|error: wx/msgdlg.h: No such file or directory

/home/coder89/Pulpit/Programy/CoderCat/globals/../include/MyClasses/../../globals/Libraries.h|13|error: wx/event.h: No such file or directory

I don't know what is wrong becouse in linker settings I have write "`wx-config --version=2.8 --static=no --unicode=yes --debug=no --libs`" and it works good. I didn't do anything with wxwidgets libraries dir.

I looks like my wxGTK suddenly disappear ;|

(It's my second time! at first time i must create my new project and copy all lines of code into them but now i have more than 20,000 lines of code and I can't do this

)

try to delete configuration-specific compiler settings (from Debug and Release separately and add just call of `wx-config --cxxflags` to common compiler settings for all configurations.
the same thing for linker but with --libs switch

But how to avoid of them??

Post by **Auria** » Sun Aug 10, 2008 7:50 pm

Try using the -fno-strict-aliasing flag

FlyingIsFun1217 · Post by **FlyingIsFun1217** » Sun Aug 10, 2008 8:32 pm

Or since you're using C::B, just go into project build options, and set it to silence all warning messages.

If I add this `--fno-strict-aliasing` the compiler can't find wxGTK headers

erm, can you post the exact compiler output? i can't see how removing a warning could prevent it from finding files

If I add this `--fno-strict-aliasing`

That should be -fno-strict-aliasing, not --. And you probably shouldn't be using backticks there.

Unless the `--fno...` was interpreted as a non-existent config option, and configure gave up in disgust
