CCS/CCSTUDIO-SAFETY: Post-build failing due to path length?

Jeremy Henderson

Part Number: CCSTUDIO-SAFETY

Tool/software: Code Composer Studio

My post-build command is set to the following:

${PROJECT_LOC}\..\..\..\..\..\..\..\..\ECP_Targets\TMS570LC4357\ECP_HAL_TMS570LC4357\data\trunk\Tools\CRC_Post_Process\postprocess.bat ${ProjName}.out ${ProjName}.map

The post build command fails with the following message:

C:/_HendersonSync/Workspaces/workspace_ECP_ALM_svn/Embedded_Controller_Platform/ECP/ECP_Modules/ECP_Data_Concentrator_Variants/ECP_DC_TMS570LC4357/data/trunk/Source/build/dc_bsp/../../../../../../../..\ECP_Targets\TMS570LC4357\ECP_HAL_TMS570LC4357\data\trunk\Tools\CRC_Post_Process\postprocess.bat dc_bsp.out dc_bsp.map

gmake[2]: [post-build] Error 2 (ignored)

Note: the above command works in the command line when run from the Debug build folder of the project.

When I hard code the path in the post-build steps, it works with no error.

Is there some limitation on the path length in CreateProcess or something?

My understanding is that the command line length for CreateProcess function is 32767 characters. However in this case, CreateProcess might be reached through cmd.exe, in which case the 8192 character command line length might apply. Does the length of your command exceed that?

No, the command length is 784 in this case. The command works fine from the command line when I run it from the project/build directory. I only get the error in the post-build step of CCS.

Could you attach the following files for us to look at:

- makefile generated by CCS for this project
- complete build log for the project (saved to a text file as described here)
- screen capture of the output when run from command line

Here is the information requested:

Post build section of makefile:
