Hi,
If you are going to implement the 'no-mmu' version of Linux Kernel (=uClinux), it is impossible to use shared libraries because each task is loaded into each (different) address.
So you must give up to compile the library 'lzo'.
Kernel/Library/Defaluts Selection --->
Customize Application/Library Settings
Exit
Exit
Library Configuration --->
Build liblzo <=== Do not select
If you want to use shared libraries, please change the kernel to mmu version. But you must also change the build tool to 'toolchain-mmu'.

Thank you so much for making it clear. Now I changed the path to only the mmu toolchain. I can perform a build but when I load it to the FPGA nothing displays. What can it be?
$ nios2-download -g newzImage Using cable "USB-Blaster ", device 1, instance 0x00
Pausing target processor: OK
Initializing CPU cache (if present)
OK
Downloaded 5709KB in 29.2s (195.5KB/s)
Verified OK
Starting processor at address 0xC1000000
developer@1604:/opt/intelFPGA_lite/16.1/nios2eds$ nios2-terminal
nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "USB-Blaster ", device 1, instance 0
nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate
I had to make these changes to make it build:
To build this thing on 64-bit ubuntu I had to do the following:
$ LIBRARY_PATH=/usr/lib/x86_64-linux-gnu
append the toolchain-mmu to your path
$ PATH=$PATH:/home/developer/altera/nios2-linux/toolchain-mmu/x86-linux2/bin
edit line 373 in /home/developer/altera/nios2-linux/linux-2.6/kernel/
timeconst.pl and remove the define so that the conditions looks like:
if (!@val)
comment out line 2
//#define _POSIX_C_SOURCE 199309
in the file /home/developer/altera/nios2-linux/uClinux-dist/user/mtd-utils/36d8de81049c9c908740b690c664b5bd3703ccd6/serve_image.c
edit the file /home/developer/altera/nios2-linux/uClinux-dist/vendors/Altera/nios2/Makefile
and remove the references to syslog.conf and sc.cfg on line 12
Now the thing builds.
