1148866 - config.mk doesn't find autoconf correctly

Status: NEW

(Firefox Build System :: General, defect)

Description

[Richard Newman [:rnewman]]

Brand new Mac, 10.10. Data, including checkouts, migrated from old machine. HomeBrew starting over from scratch.


Installed autoconf following instructions here:

https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Mac_OS_X_Prerequisites



$ ./mach configure
 0:00.22 /usr/bin/make -f client.mk -s MOZ_PARALLEL_BUILD=8 -s configure
 0:00.86 client.mk:304: *** Could not find autoconf 2.13.  Stop.


It should be doing this:

# try to find autoconf 2.13 - discard errors from 'which'
# MacOS X 10.4 sends "no autoconf*" errors to stdout, discard those via grep
AUTOCONF ?= $(shell which autoconf-2.13 autoconf2.13 autoconf213 2>/dev/null | grep -v '^no autoconf' | head -1)



On 10.10, running that multi-arg which variant:

$ which autoconf-2.13 autoconf213
autoconf-2.13 not found
/usr/local/bin/autoconf213

$ which autoconf213
/usr/local/bin/autoconf213


If I add 

mk_add_options AUTOCONF=/usr/local/bin/autoconf213

to my .mozconfig, ./mach configure completes successfully.
