Can't find #include files

[simonl]

I've just installed C::B and tried to transfer some existing code to it.  I split it into two projects:

lib      - builds a library which is used by ...

tests  which consists of s set of separate, single file programs which test various aspects of the lib and which depends upon it.


The lib build worked fine first time (congrats to C::B team - a very professional product).  The tests project dependency works fine.

The test programs use the same headers as the lib project so I added the header directory to project tests Properties ... -> c/c++ parser options as an additional search path.  Just to be doubly sure I added it to the Build options... ->search directories->compiler  tab (I'm not yet sure what the difference is between the two places).  But it doesn't find the include files.  

I turned full logging on and the g++ command for the first test is:

mingw32-g++.exe   -c P:\eacp\test\polydomaintest.cpp -o \polydomaintest.o

I'd expect it to also have:   -Ip:\eacp\include 

Also what's with -o \polydomaintest.o ... shouldn't it be -o .\polydomaintest.o or just -o polydomaintest.o

Any ideas what I'm doing wrong?

Thanks

Simon

Please post your project file and we most likely can tell.

Thanks for the quick reply.  Here's the "test" project file.

Change projects "Properties... -> Build targets -> Debug -> Type" to "Console application" or whatever type it should be. Don't use "Commands only" !!

Btw. the "Release" build target seems to be correct.

[simonl]

Thanks.  The project contains lots of separate programs - I'd guessed (wrongly) that "Commands Only" wouldn't try and link everything together.  Is it easier to just provide a make file to produce lots of exe files in one directory? Before trying C::B I tended to use ad hoc make files but thought maybe I wouldn't need then any more.

I have the same problem, although my are already set to Console application.. I am migrating from Xcode to Code::Blocks for Windows users but when I try to compile the file I'm getting the following error:

Code

ofxCvHaarFinder.h: No such file or directory

CBP-file in which the file in the path to ofxCvHaarFinder.h is present..

Thanks for your help in advance

CBP-file in which the file in the path to ofxCvHaarFinder.h is present..

It is not. You need to pass the path to the header file to the compiler using the compiler include path in the project's build options. It's not enough to "tell" C::B only where the header file is. The compiler needs to know, too.

[Jenna]

It seems you have many files added twice to your project, one time in a directoy below your projects root dir (e.g. "src\ofxCvHaarFinder\ofxCvHaarFinder.h") and once in a directory outside your projects directory-structure (e.g. "..\..\..\addons\ofxCvHaarFinder\ofxCvHaarFinder.h").

Which one is the right ?

None of your search dirs points to a directory inside your project.

The first thing would be to clean up your project, so that you only use files belonging to it, remove all others, the set up your search dirs correctly to the paths you use, e.g. " src\ofxCvHaarFinder\" if you use "#include ofxCvHaarFinder.h", or just "src" if you use "#include ofxCvHaarFinder\ofxCvHaarFinder.h". If header and source file are in the same directory no search path is needed.

If you need to have files with the same name inside your project, it's not so easy to set it up correctly, so that cpp-files always find the correct headers.

[Veremos]

Setting the search dir, and some cleaning work indeed, did the job. Thanks a LOT for your quick reply!
