Summary:                    bad compiler version discover in dependencies.sh
Description: 
Hello,
I don't know wheter or not $HOSTCC have to be defined before lauching
'make'.

Anyway, when not configured, the following test fails:
COMPILER=$(which $HOSTCC)

'which' gracefully respond with helps text....
that next $XSED is unable to understand ;)

file:
toolchain/dependencies/dependencies.sh; line
http://busybox.net/bugs/view.php?id=208#152


Bye

same for $HOSTCXX, next test.

Note also 'head' is used before testing presence by the script.

HOSTCC and HOSTCXX are optional.

Please post the exact error you are seeing.

I don't understand why you point to an unrelated comment? Please
elaborate.

Hello,

Just log all the make programs output to see details of the error.
Or ever simpler: go directly in dependencies subir and lauch
dependencies.sh.
It tests every needed support program presence (except for 'head')
and it completly fails the compiler test version
WHEN HOSTCC IS NOT SET (then HOSTCXX)
Can't be more clear than that, sorry.

Asking 'which something' returns pathto something
Asking 'which' returns which's syntax usage.

Guess what happens when HOSTSCC is empty....

I understand why you don't understand the comment...

The link-pointer was a real text entered by me and it is the mantis bug
tracking system that replaced it.

foo=$(which) does not print anything for me.

what version of which do you see this with?

i replaced the use of head with sed -e '1d', please svn up and let me know
if that's better now.

PS: If you don't provide a copy and paste of the error you are getting
from dependencies.sh with HOSTCC and HOSTCXX unset, then i'll blissfully
ignore this part of your report. Thanks for your understanding.

my which prog comes from 'gnu' repository.
It does not print anything too, from command line.

but inside the script, it is not the same !?

Also, another thing changed in my system and now, dependencies.sh finds
the rigth version of gcc. Previously, it was an error message with
something 'not numeric'.
