[bitbake-devel] [PATCH 4/6] bitbake: data_smart: fix filename for compile()

[Robert Yang]

Fixed:
Add the following two lines to conf/local.conf:
FOO = "${@foo = 5}"
HOSTTOOLS += "${FOO}"

* Before the patch
  $ bitbake -p
  Check the first lines of bitbake bitbake-cookerdaemon.log
  [snip]
  File "/buildarea1/lyang1/poky/bitbake/lib/bb/data_smart.py", line 125, in python_sub
    codeobj = compile(code.strip(), self.varname or "<expansion>", "eval")
  File "FOO", line 1
  [snip]

  There isn't a file named 'FOO', but a variable name.

* After the patch
  $ bitbake -p
  [snip]
  File "/buildarea1/lyang1/poky/bitbake/lib/bb/data_smart.py", line 129, in python_sub
    codeobj = compile(code.strip(), varname, "eval")
  File "Var <FOO>", line 1
    foo = 5
