Include Library in project

i think u have to include ur library by hand in the makefile of your project.

# List of include directories for -I compiler option (-I added when used).

# Includes the BSP.

ALT_INCLUDE_DIRS := "." "./src/include" "./src/include/ipv4"

# List of library directories for -L linker option (-L added when used).

# Includes the BSP.

ALT_LIBRARY_DIRS :=

Hi,

thanks for your answer, but the problem is still the same.

Here's the output from my console:

/cygdrive/c/altera/91sp2/nios2eds/bin/nios2-gnutools/H-i686-pc-cygwin/bin/../lib/gcc/nios2-elf/3.4.6/../../../../nios2-elf/bin/ld: cannot find -ltestLib.a

I had these makefile changes before in APP_LIBRARY_DIRS and APP_LIBRARY_NAMES.

Any other suggestions?

Could it be a problem, that my nios stuff, like the compiler and so on is located on another partition than my project?

Hi,

so I have an update on my problem. For now i found a workaround which isn't nice but seems to work.

I created the lib, name it libA, as described in the documentation, then created another library, named libB, without any c-code in it and copied the libA in. Afterwards I renamed libA to libB.

Now i can include libB as a library project to my original project. I'm going to try to use this approach on another pc, where the original code for the lib isn't present.

I'll report on any progress

I'm trying to pack parts of my NIOS-Code as a library

All I have to do is described on Page 25.

The creating part of the library is working very well,/QUOTE]

I too wish to pack some of my c functions as a library.

I have tried various approaches, based on p 2-25, and get empty archives (using V12.0sp2)

It does not seem to be compiling the c to .o .....

Any suggestions ?

I have created a library by hand editing a makefile,

and now of course want to link it to a small function.

All my attempts to get DE1 runnable code have failed - any suggestions ?

cheers,

Beau

OK,

The secret seems to be as follows :

1) Use Eclipse to edit the Makefile - that way you will get the right copy.

2) create a directory lib and put the library libaplc.a into it, then

set : ALT_LIBRARY_DIRS := lib

3) set : ALT_LIBRARY_NAMES := aplc

4) set : ALT_LDDEPS := D:\home\jbww\Design\Altera\Eclipse_v12\NiosProjects\aplc_matrix\lib\libaplc.a

I have had to simplify the I/O for the moment, but I can now translate Apl to c using aplc., and have it compile and run on the DE1 board :

The same partially gutted library source compiles OK on the Altera NiosII.

Here is a simple set of matrix operations in a function "matrix":

Source in AplX:

'C: inner product:'

C ← A ∘.× B

'T: transpose:'

T ← ⍉ C

'O: outer product (matrix multiply):'

O ← C +.× T

' '

'S: solve matrix:'

S ← C ⌹ A
