Kintex-7 FPGA Embedded Kit - Compiling webserver application cannot find “lmfsimage”

Description

The Kintex-7 FPGA Embedded Kit design files compile "out of the box". However, when I attempt to rebuild the Webserver application for KC705 Embedded Kit, the following error occurs:
 
"Building target: board_test_app_Webserver.elf

 collect2: ld returned 1 exit status
 make: *** [board_test_app_Webserver.elf] Error 1" 

How can I resolve this issue?

Solution

If this error is seen when recompiling, the library search path is not set to the memfs folder. To resolve this, follow these steps in SDK:

  1. Right-click over the board_test_app_Webserver project > Project settings.
  2. Go to Settings -> Microblaze gcc linker -> Libraries.
  3. The -l switch should point to "mfsimage".
  4. The -L switch should point to the memfs folder location.
  5. Click OK. This will compile the webserver application without any errors.
