just a minor cosmetic thing:
Code: Select all
make[1]: Entering directory 'src'
egrep: warning: egrep is obsolescent; using grep -E
grep: warning: stray \ before #
egrep: warning: egrep is obsolescent; using grep -E
grep: warning: stray \ before #
egrep: warning: egrep is obsolescent; using grep -E
grep: warning: stray \ before #
egrep: warning: egrep is obsolescent; using grep -E
grep: warning: stray \ before #
egrep: warning: egrep is obsolescent; using grep -E
grep: warning: stray \ before #
egrep: warning: egrep is obsolescent; using grep -E
grep: warning: stray \ before #
* it seems using
[font=monospace]egrep[/font] is depreciated and
[font=monospace]grep -E[/font] should be used instead. egrep is used quite often:
Code: Select all
$ grep -r egrep external/ChibiOS/* | wc
112 1257 17896
* the other warning is about an
unnecessary backslash before a hash. i used to see sthg like this

Hi,
I am not seeing any warning on Linux Mint or in Windows GNU utils from MinGW, replaced egrep anyway.
The \ fixes a syntax highlighting issue in Eclipse for makefiles, without that all the text is gray after the #.

It is the same version here, strange, maybe it is affected by some env var.
