Sourcing a shell script within a bbclass
|
Elvis Dowson
Hi, How can I source a shell script within a bbclass? For example, in meta-xilinx/classes/xilinx-boot.bbclass, I need to source a script file called settings64.sh, which setups the environment variables for the Xilinx ISE 14.1 design tools, in order to generate a system ace image file. For the following code snippet: if [ "${XILINX_VER}" \> "14" ]; then bbnote "XILINX_VER ${XILINX_VER}, script location ${XILINX_LOC}/${EDK_SCRIPT}" source ${XILINX_LOC}/${EDK_SCRIPT} ${XILINX_LOC} fi I get the following error: DEBUG: Executing python function sstate_task_prefunc DEBUG: Python function sstate_task_prefunc finished DEBUG: Executing shell function do_deploy ERROR: Function failed: do_deploy (see /tool/yocto/poky/build/tmp/work/ppc440-poky-linux/u-boot-xilinx-v2012.04.01-r16/temp/log.do_deploy.15616 for further information) NOTE: Deploying uboot elf image to /project/xilinx-ml507 NOTE: Xilinx design tools installed in /tool/xilinx/14.1/ISE_DS NOTE: Generate system ace image NOTE: EDK_SCRIPT settings64.sh NOTE: XILINX_VER 14.1, script location /tool/xilinx/14.1/ISE_DS/settings64.sh /tool/yocto/poky/build/tmp/work/ppc440-poky-linux/u-boot-xilinx-v2012.04.01-r16/temp/run.do_deploy.15616: 129: /tool/yocto/poky/build/tmp/work/ppc440-poky-linux/u-boot-xilinx-v2012.04.01-r16/temp/run.do_deploy.15616: source: not found if I replace the source keyword with a . (dot) if [ "${XILINX_VER}" \> "14" ]; then bbnote "XILINX_VER ${XILINX_VER}, script location ${XILINX_LOC}/${EDK_SCRIPT}" . ${XILINX_LOC}/${EDK_SCRIPT} ${XILINX_LOC} fi it executes the scripts but gives the following error: NOTE: XILINX_VER 14.1, script location /tool/xilinx/14.1/ISE_DS/settings64.sh /tool/yocto/poky/build/tmp/work/ppc440-poky-linux/u-boot-xilinx-v2012.04.01-r16/temp/run.do_deploy.7879: 12: [: /tool/yocto/poky/build/tmp/work/ppc440-poky-linux/u-boot-xilinx-v2012.04.01-r16/temp/run.do_deploy.7879: unexpected operator . /tool/xilinx/14.1/ISE_DS/common/.settings64.sh /tool/xilinx/14.1/ISE_DS/common . /tool/xilinx/14.1/ISE_DS/EDK/.settings64.sh /tool/xilinx/14.1/ISE_DS/EDK . /tool/xilinx/14.1/ISE_DS/common/CodeSourcery/.settings64.sh /tool/xilinx/14.1/ISE_DS/common/CodeSourcery . /tool/xilinx/14.1/ISE_DS/PlanAhead/.settings64.sh /tool/xilinx/14.1/ISE_DS/PlanAhead . /tool/xilinx/14.1/ISE_DS/../../Vivado/2012.1/.settings64.sh /tool/xilinx/14.1/ISE_DS/../../Vivado/2012.1 . /tool/xilinx/14.1/ISE_DS/ISE/.settings64.sh /tool/xilinx/14.1/ISE_DS/ISE . /tool/xilinx/14.1/ISE_DS/SysGen/.settings64.sh /tool/xilinx/14.1/ISE_DS/SysGen What should I do to source the settings64.sh file properly within the bbclass? Best regards, Elvis Dowson |

The problem was because of Ubuntu 12.04 shell being configured by default to use dash, instead of bash. After I reconfigured the shell to use bash using the command: $ sudo dpkg-reconfigure dash everything works fine. However, Yocto 1.2 defaults or assumes that the user will use dash. Is there anyway I can fix this issue, so that the bbclass works for both dash and bash. Using the . (dot) to source the script doesn't seem to work, so I was wondering if there are any other workarounds that I can use to emulate bash's sourcing behaviour in dash. Best regards, Elvis Dowson |

The settings64.sh script from Xilinx, when run stand-alone runs perfectly fine in Dash, so I don't think there is any bashism there. The problem is with the yocto build system I think, because it gives a unexpected error message as show above.ubuntu likes the . operator Best regards, Elvis Dowson |
