During ./configure of flex-2.5.37 on the raspberrypi I get an error:

 

“M4 that supports –P”

 

 

M4 (latest) is built with success…

Any tip/hint?

 $ export M4=`which gm4`

 $ if test -z "$M4" || test -z "`$M4 --help 2>&1 |grep prefix-builtins 2>/dev/null`"; then M4=`which m4`; fi

 $ $M4 --help |grep prefix-builtins

If the last command above is a string containing prefix-builtins, they building flex with M4 set like that. Otherwise download ftp://ftp.gnu.org/gnu/m4/m4-1.4.16.tar.gz, unpack it, configure with:

 $ ./configure --prefix=$HOME --program-transform-name='s|^|g|'

 $ make all install

 $ export M4=$HOME/bin/gm4

And try building flex again.
