[issues] [Configure eglibc] No acceptable grep could be found

[Olivier Antheaume <olivier.antheaume@xxxxxxxxx>]

Hello,

when I configure eglibc, I have the following error:

running configure fragment for ports/sysdeps/unix/sysv/linux/mips

running configure fragment for nptl/sysdeps/pthread

running configure fragment for sysdeps/pthread

running configure fragment for sysdeps/unix/sysv/linux

checking for grep that handles long lines and -e... Usage: /bin/grep [OPTION]... PATTERN [FILE]...

Try `/bin/grep --help' for more information.

configure: error: no acceptable grep could be found in /usr/local/bin:/usr/bin:/bin:/usr/games:/usr/xpg4/bin

I have grep-2.5.4 installed on my computer.
As it is the last version, I think that it should support long lines.

I have found that the error was generated in the libc/sysdeps/unix/sysv/linux/configure file.

To validate this hypothesis, I have commented the following bloc of code in this file:

{ echo "$as_me:$LINENO: checking for grep that handles long lines and -e" >&5

echo $ECHO_N "checking for grep that handles long lines and -e... $ECHO_C" >&6; }

if test "${ac_cv_path_GREP+set}" = set; then

echo $ECHO_N "(cached) $ECHO_C" >&6

else

# Extract the first word of "grep ggrep" to use in msg output

if test -z "$GREP"; then

set dummy grep ggrep; ac_prog_name=$2

if test "${ac_cv_path_GREP+set}" = set; then

echo $ECHO_N "(cached) $ECHO_C" >&6

Without this code, I haven't the error message, and I can install eglibc-headers.

So have you a more precise idea of the problem ?
A cleaner patch ?

According to the error message, I think that a command in this part of the configuration file is incorrect. But I don't know which one.
