Includes

[Altera_Forum]

Hello! 

 I include some headers in one c-file of a project. These headers are in other directories as the c-file.  I can't use absolute paths to include the header files, because the headers include files in there own directory.  So I open in system properties "C/C++ Inclde Paths & Symbols". Here I add via button "Add External Include Path..." the directory of the header-files and their includes. But when I compile again the compiler can't still find headers.  What is going wrong?  Bye, Lothar.

include "../../a.h" //as an example

Hi Mountain! 

 Sorry, I didn't mention that I don't want to use relative paths too. I'm searching for a possibility to set include paths for the compiler for a project in Nios II.   Bye, Lothar.

I ran into the same problem. The project properties setting doesn&#39;t seem to do anything with regards to the path settings.

Could you post your makefile?

Hi Mountain! 

 My makefile is: ifneq ($(KERNELRELEASE),)# kbuild part of makefile obj-m := hello.o else# Normal Makefile KERNEL_PLUGIN:= /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_1.4.0 KERNELDIR := $(KERNEL_PLUGIN)/linux-2.6.x BUILDDIR := /cygdrive/c/Entwicklung/NIOS/workspace3/hello_driver_linux all::     $(MAKE) -C $(KERNELDIR) M=`pwd` O=$(BUILDDIR) -o $@ endif  And it&#39;s making a lot of compiler errors, which caused by path problems.   Bye, Lothar.
