How to use manage system library project?

Hi All,

Few days back i wrote one thread about software code protection.After studying some more depth in NIOS IDE i am getting

1) managed system library

2) system library project.

Now the first project just build the library.It will never ask for the *.ptf file.Means it is totaly independent from target hardware. I created that one.

Now the issue is that i developed a code and that i want to protect from out side.Now this code also contain some use of NIOS HAL.ok. To build this library i assign the path of that NIOS HAL and get successfully build of my library. Now,my library contain *c and *.h file and it also use some NIOS HAL,that i already mentioned above.

Now i made simple C/C++ application in another workspace and give the path in linker option for created library.

Now when i build the programe NIOS IDE auto generate alt_sys_init.c file and that contain INSTANCE and INIT function of our device HAL driver.OK.Now i get the entry of my HAL driver in that.So it means thats perfectly work.But now waht happen the function inside my library(HAL driver function) will not call from this c/c++ application project.and give the error that the functions are undefined.

If any one having any idea about that then help me ASAP.

Best Regards,

slsnios.....

    did you checked if in the application project you have the library listed in the linker command? --> try remove the "-s" parameter from the make command (e.g., you can run it from the Nios II SDK shell) to get the output of the commands run.

    Hi paolo.gai

    I really thanx to you.U are giving me every time reply related on Library. I managed for that C++ library but for my HAL i coudnt manage that thing. I already include *.h file of HAL in my C/C++ application and import the library through linker option that gave by NIOS IDE.ok

    But as u know when i build the project it will generate alt_sys_init.c file and in that it will make entry of all device driver with its INSTANCE and INIT. right. So i already got my INSTANCE and INIT in that but as u knw our INSTANCE and INIT contain some function and that i couldnt get in my project.

    Paolo ifyou are not getting me then plz ask me that thing becoz from last some days i m not getting to solve this thing and want to over it.I hope u will give me good support as like befor. Really thankfull to you.

    Best Regards,

    Hi...

    sorry for the delay, I was out of town last week...

    - the "-s" parameter is used automatically by the IDE to remove the command lines of the command it executes... I was saying that because in that way you get the commands executed to compile the system and you can understand what&#39;s is going on.

    - the reason why I&#39;m always giving you replies on libraries is because we implemented it that way for ERIKA Enterprise. Did you take a look at the Demo version of ERIKA Enterprise? we distribute our kernel with a binary library...

    - as an alternative, you can compile your code, and ask your customers to put the .o/.h files inside the project, and then to add the right commands inside the project properties...

    bye
