AR# 31067 10.1 EDK - Using G++ (C++) for PowerPC 440 gives the error "undefined reference to `XCache_EnableICache(unsigned int)"

Description

Keywords: compile, C, C++, GCC, G++, Power, PC, 440

When I use the C++ compiler (G++) with the Standalone OS or Xilkernel, I receive undefined reference errors similar to the following:

"tmp/ccI8W9s5.o: In function `main':
/project/TestApp_Peripheral/src/TestApp_Peripheral.c:47: undefined reference to `XCache_EnableICache(unsigned int)'
/project/TestApp_Peripheral/src/TestApp_Peripheral.c:48: undefined reference to `XCache_EnableDCache(unsigned int)'
/project/TestApp_Peripheral/src/TestApp_Peripheral.c:58: undefined reference to `XCache_DisableDCache()'
/project/TestApp_Peripheral/src/TestApp_Peripheral.c:59: undefined reference to `XCache_DisableICache()'
collect2: ld returned 1 exit status
make: *** [TestApp_Peripheral/executable.elf] Error 1"

Solution

C++ guards were not added to certain key files. Below is a patch that will correct the problem:

1. Download the patch:
http://www.xilinx.com/txpatches/pub/swhelp/ise10_updates/ppc_440_c_plus_plus_patch.zip

2. Extract the patch into the $XILINX unified installation area (for example, $XILINX=C:\Xilinx\10.1) overwriting the existing files.

This problem has been fixed in the latest 10.1 Service Pack available at:
http://www.xilinx.com/support/download/
The first service pack containing the fix is 10.1 Service Pack 3.
