How to #include a driver from a IP component to my construction, in Nios II?

Hi. I have a difficult problem (task), that is for me important to solve for finishing my construktion.

I have search for any solution on the net for several months, and I need some expert help.

The most of it is already finished and tested. But the customer really needs the VGA-driver for the construction, to be saved inside his IP-component, instead of inside the project map.

When I tries to include the driver, #include <VGA_driver.h> , in the top of the main .c file (Hello world), I got the error message: hello_world.c:37:24: fatal error: VGA_driver.h: No such file or directory. When I writes the link in the .tcl file (or c-file), to the VGA driver, it expects it to be in the project folder (in the inc folder with the other .h files).

I have tried to add the link address into the makefile (but the error remains the same).

I have also included the driver in the project as a file and as a link, (but the error remains the same).

How do I solve this matter?

The project folder is:

The customer wants the driver in this directory instead:

VGA_driver_sw.tcl below:

create_driver VGA_driver_sw
set_sw_property hw_class_name VGA_driver
set_sw_property version 1
set_sw_property min_compatible_hw_version 1.0
add_sw_property bsp_subdirectory drivers
add_sw_property c_source <d://AGSTU/Kurs_C/C_engineering_job/IP/DE10_Lite_VGA_IP/HAL/src/VGA_driver.c #Alt 3. Doesn't work.
add_sw_property c_source <d://AGSTU/Kurs_C/C_engineering_job/IP/DE10_Lite_VGA_IP/HAL/src/draw_vga.c #Alt 3. Doesn't work.
# add_sw_property c_source IP/DE10_Lite_VGA_IP/HAL/src/VGA_driver.c #Alt 2. Doesn't work.

# add_sw_property include_source IP/DE10_Lite_VGA_IP/HAL/inc/VGA_driver.h #Alt 2. Doesn't work.

    I think I got the construction to work now. The errormessage has disappeared. The file seems to be found.

    Thanks for all help. Hareesh, you are a hero. I have asked others about this matter. You are the one that have guided me to an solution.

    No I haven't add it. I uses my own VGA function instead of the customers IP component.

    Mayby I have to add it to make it work.

    I attach my construction in this message.

      Hi @Hakan_H,

      first have to add VGA IP in platform design then only you use those drivers.

      thanks,

    OK, many thanks for your help. It's very valuble for me. The idea isn't to use the drivers of the VGA IP. I gonna use my own drivers for the construction instead (that I know works perfectly). But for some reason (that I don't understand), the customer wants (demands), me to use his VGA IP to store my drivers in.

    But the customer gets what the customer wants. I hope he likes the invoice I am gonna send him for the work.

    I thougt it was an easy job just to link to his IP component from my construction thru an .tcl file.

    The construction is almost finished and working, exept for the linking part. So I will not inplement his cunstrucktion (IP component), into mine in this stage. Becauce it will take me much more time (that I don't have at the moment).

    But I will follow your tip to add his VGA IP and link to it from there. I will also com back to you with the result.

    Best regards. Håkan.
