[bitbake-devel] [PATCH 1/6] bitbake: utils: better_compile(): Fix line number when report errors

Fixed:
- Add an error line in base.bbclass, e.g.:
15
16 def oe_import(d):
17 import sys
18 Compile error
19 bbpath = d.getVar("BBPATH").split(":")
[snip]
Note the "Compile error" line, I added it for reporting errors.
$ bitbake -p
ERROR: Error in compiling python function in /buildarea1/lyang1/poky/meta/classes/base.bbclass, line 15:
The code lines resulting in this error were:
0014: import oe.data
0015: for toimport in oe.data.typed_value("OE_IMPORTS", d):
0016: imported = __import__(toimport)
0017: inject(toimport.split(".", 1)[0], imported)
*** 0018:
0019: return ""
0020:
SyntaxError: invalid syntax (base.bbclass, line 18)
There are 2 problems:
- The "line 15" is incorrect, it is a blank line, not the error line.
- The "*** 0018" points to incorrect position.
These two problems would mislead people a lot sometimes.
- Now fix it to:
$ bitbake -p
ERROR: Error in compiling python function in /buildarea1/lyang1/poky/meta/classes/base.bbclass, line 18:
The code lines resulting in this error were:
0001:def oe_import(d):
0002: import sys
*** 0003: Compile error
0004: bbpath = d.getVar("BBPATH").split(":")
[snip]
SyntaxError: invalid syntax (base.bbclass, line 18)
Please see comments in the code for more details on how it is fixed.
