Detailed analysis of ACE program porting in Embedded Linux

Article Title: detailed analysis of ACE program porting in embedded Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

1. Install the cross compiler on a PC with a Linux operating system. I use Moxa tool chain for DA66x (the same is true for other embedded Linux systems ), you can download it from the Moxa Website:

Linux/V1.0/Linux_tool-chain_1.0.zip "> http://www.moxa.com/drivers/UC/DA_66X_LX/tool_chain/linux/V1.0/Linux_tool-chain_1.0.zip

2. Download the ACE package to a Linux PC and decompress it.

3. Set environment variables:

A. PATH of the Cross-compilation tool: export PATH = "/usr/local/xscale_be/bin: $ PATH"

B. ACE_ROOT: export ACE_ROOT = "/home/jun/ACE_wrappers" (set according to the actual path)

4. Copy $ ACE_ROOT/ace/config-linux.h to $ ACE_ROOT/ace/config. h

Cp $ ACE_ROOT/ace/config-linux.h $ ACE_ROOT/ace/config. h

5. Copy $ ACE_ROOT/include/makeinclude/platform_linux.GNU

$ ACE_ROOT/include/makeinclude/platform_macros.GNU and modify

$ ACE_ROOT/include/makeinclude/platform_macros.GNU file:

Add:

CC = xscale_be-gcc

CXX = xscale_be-g ++

Delete:

insure ?= 0ifeq ($(insure),1) CC = insure CXX = insureelse CC ?= gcc CXX ?= g++endif

6. Modify the $ ACE_ROOT/include/makeinclude/platform_g ++ _ common. GNU file, and comment the 90th rows: LDFLAGS + =-Wl,-E

7. Enter $ ACE_ROOT and directly enter make

8. Convert the generated libACE. copy so.5.5.6 to the cfcard/mnt/had/lib of DA66x, edit/etc/profile of DA662, and add export LD_LIBRARY_PATH = "/mnt/hda/lib to the file: $ LD_LIBRARY_PATH"

9. In addition, the test programs under the gperf directory cannot be compiled because they must pass.

$ (ACE_ROOT)/apps/gperf/src/The gperf program generated by the relevant source code in the directory to complete the next action, which is generated by the cross compiler, cannot run on PC. Therefore, after all: In GNUmakefile, We need to delete the target objects cppinset adainset cinset iinset iinset2 m3inset pinset preinset taoinset tinset.

10. The entire compilation process takes about 30 minutes, depending on the machine performance.

Episode: At first I used platform_macosx.GNU. I made appropriate adjustments to this file and named it platform_macros.GNU, because they are similar. The compilation was quite smooth at the beginning, but soon (when ACEXML was compiled) It couldn't be compiled, and it was dizzy! The generated libACE. so library is also faulty! Later, I saw other netizens compile ACE in Linux on the Internet. I was inspired to switch to platform_linux.GNU and directly

Add:

CC = xscale_be-gcc

CXX = xscale_be-g ++
