configure error line 2433: syntax error near unexpected token `m4'

After autogen.sh without any warning or error,

fsw# ./configure
./configure: line 2433: syntax error near unexpected token `m4'
./configure: line 2433: `AC_CONFIG_MACRO_DIRS(m4)'

@muyinliu, are you sure:

• You executed autogen.sh and it exited with no error.
• autogen.sh created configure.
• You are really executing configure.

With no further clues, I guess you're trying to execute configure.ac, which is not an executable file. The AC_CONFIG_MACRO_DIRS macro is contained in configure.ac and it's expanded when configure is created: that is, configure will never contain it literally.

Cheers, -- Enrico

That's weird indeed, @muyinliu. Can you send me the configure file?

Prefer a ksh shell builtin over an external printf program on Solaris,

but without wasting forks for bash or zsh.

IFS

We need space, tab and new line, in precisely that order. Quoting is

there to prevent editors from complaining about space-tab.

(If _AS_PATH_WALK were called with IFS unset, it would disable word

splitting by setting IFS to empty value.)

IFS=" "" $as_nl"

Find who we are. Look in the path if we contain no directory separator.

esac

We did not find ourselves, most probably we were run as `sh COMMAND'

in which case we are not to be found in the path.

Unset variables that we do not need and which cause bugs (e.g. in

pre-3.0 UWIN ksh). But do not cause bugs in bash 2.01; the "|| exit 1"

suppresses any "Segmentation fault" message there. '((' could

trigger a bug in pdksh 5.2.14.

---------------------

M4sh Shell Functions.

---------------------

as_fn_unset VAR

---------------

Portably unset VAR.

as_fn_unset () { { eval $1=; unset $1;} } as_unset=as_fn_unset

as_fn_set_status STATUS

-----------------------

Set $? to STATUS, without forking.

as_fn_set_status () { return $1 } # as_fn_set_status

as_fn_exit STATUS

-----------------

Exit the shell with STATUS, even in a "trap 0" or "set -e" context.

as_fn_exit () { set +e as_fn_set_status $1 exit $1 } # as_fn_exit

as_fn_mkdir_p

-------------

Create "$as_dir" as a directory, including parents if necessary.

as_fn_mkdir_p () {

case $asdir in #( -) as_dir=./$as_dir;; esac test -d "$as_dir" || eval $as_mkdir_p || { as_dirs= while :; do case $asdir in #( *\') as_qdir=$as_echo "$as_dir" | sed "s/'/'\\\\\\\\''/g";; #'( _) as_qdir=$as_dir;; esac as_dirs="'$as_qdir' $as_dirs" as_dir=$as_dirname -- "$as_dir" || $as_expr X"$as_dir" : 'X(._[^/])//_[^/][^/]_/_$' | \ X"$as_dir" : 'X(//)[^/]' | \ X"$as_dir" : 'X(//)$' | \ X"$as_dir" : 'X(/)' | . 2>/dev/null || $as_echo X"$as_dir" | sed '/^X(._[^/])\/\/_[^/][^/]_\/_$/{ s//\1/ q } /^X(\/\/)[^/]._/{ s//\1/ q } /^X(\/\/)$/{ s//\1/ q } /^X(\/)._/{ s//\1/ q } s/._/./; q' test -d "$as_dir" && break done test -z "$as_dirs" || eval "mkdir $as_dirs" } || test -d "$as_dir" || as_fn_error $? "cannot create directory $as_dir"

} # as_fn_mkdir_p

as_fn_executable_p FILE

-----------------------

Test if FILE is an executable regular file.

as_fn_executable_p () { test -f "$1" && test -x "$1" } # as_fn_executable_p

as_fn_append VAR VALUE

----------------------

Append the text in VALUE to the end of the definition contained in VAR. Take

advantage of any shell optimizations that allow amortized linear growth over

repeated appends, instead of the typical quadratic growth present in naive

implementations.

if (eval "as_var=1; as_var+=2; test x\$as_var = x12") 2>/dev/null; then : eval 'as_fn_append () { eval $1+=\$2 }' else as_fn_append () { eval $1=\$$1\$2 } fi # as_fn_append

as_fn_arith ARG...

------------------

Perform arithmetic evaluation on the ARGs, and store the result in the

global $as_val. Take advantage of shells that can avoid forks. The arguments

must be portable across $(()) and expr.

if (eval "test \$(( 1 + 1 )) = 2") 2>/dev/null; then : eval 'as_fn_arith () { as_val=$(( $* )) }' else as_fn_arith () { as_val=expr "$@" || test $? -eq 1 } fi # as_fn_arith

as_fn_error STATUS ERROR [LINENO LOG_FD]

----------------------------------------

Output "basename $0: error: ERROR" to stderr. If LINENO and LOG_FD are

provided, also output the error to LOG_FD, referencing LINENO. Then exit the

script with STATUS, using 1 if that was 0.

as_fn_error () { as_status=$1; test $as_status -eq 0 && as_status=1 if test "$4"; then as_lineno=${as_lineno-"$3"} as_lineno_stack=as_lineno_stack=$as_lineno_stack $as_echo "$as_me:${as_lineno-$LINENO}: error: $2" >&$4 fi $as_echo "$as_me: error: $2" >&2 as_fn_exit $as_status } # as_fn_error

if expr a : '(a)' >/dev/null 2>&1 && test "Xexpr 00001 : '.*\(...\)'" = X001; then as_expr=expr else as_expr=false fi

if (basename -- /) >/dev/null 2>&1 && test "Xbasename -- / 2>&1" = "X/"; then as_basename=basename else as_basename=false fi

if (as_dir=dirname -- / && test "X$as_dir" = X/) >/dev/null 2>&1; then as_dirname=dirname else as_dirname=false fi

as_me=$as_basename -- "$0" || $as_expr X/"$0" : '.*/\([^/][^/]*\)/*$' \| \ X"$0" : 'X\(//\)$' \| \ X"$0" : 'X\(/\)' \| . 2>/dev/null || $as_echo X/"$0" | sed '/^.*\/\([^/][^/]*\)\/*$/{ s//\1/ q } /^X\/\(\/\/\)$/{ s//\1/ q } /^X\/\(\/\).*/{ s//\1/ q } s/.*/./; q'

Avoid depending upon Character Ranges.

as_cr_letters='abcdefghijklmnopqrstuvwxyz' as_cr_LETTERS='ABCDEFGHIJKLMNOPQRSTUVWXYZ' as_cr_Letters=$as_cr_letters$as_cr_LETTERS as_cr_digits='0123456789' as_cr_alnum=$as_cr_Letters$as_cr_digits

as_lineno_1=$LINENO as_lineno_1a=$LINENO as_lineno_2=$LINENO as_lineno_2a=$LINENO eval 'test "x$as_lineno_1'$as_run'" != "x$as_lineno_2'$as_run'" && test "xexpr $as_lineno_1'$as_run' + 1" = "x$as_lineno_2'$as_run'"' || {

Blame Lee E. McMahon (1931-1989) for sed's syntax. :-)

sed -n ' p /[$]LINENO/= ' <$asmyself | sed ' s/[$]LINENO./&-/ t lineno b :lineno N :loop s/[$]LINENO([^'$as_cralnum'].\n)(.)/\2\1\2/ t loop s/-\n._// ' >$as_me.lineno && chmod +x "$as_me.lineno" || { $as_echo "$as_me: error: cannot create $as_me.lineno; rerun with a POSIX shell" >&2; as_fn_exit 1; }

If we had to re-execute with $CONFIG_SHELL, we're ensured to have

already done that, so ensure we don't try to do so again and fall

in an infinite loop. This has already happened in practice.

_as_can_reexec=no; export _as_can_reexec

Don't try to exec as it changes $[0], causing all sort of problems

(the dirname of $[0] is not the place where we might find the

original and so on. Autoconf is especially sensitive to this).

@muyinliu, I believe your fsw source and build directory is broken somehow. I guess you did it, but could you please clone the repository again and start from fresh? I can't reproduce this issue.

[muyinliu]

OK. I clone again, and something new appear: fsw# ./autogen.sh configure.ac:11: error: possibly undefined macro: AC_CONFIG_MACRO_DIRS If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. autoreconf: /usr/local/bin/autoconf failed with exit status: 1

[emcrisostomo]

Cool, that confirms that you're missing the AC_CONFIG_MACRO_DIRS macro, which was added by automake in version 1.13, IIRC. Can you please confirm your automake installation is older?

If it is, you could either:

• Upgrade automake.
• Check whether changing AC_CONFIG_MACRO_DIRS to AC_CONFIG_MACRO_DIR in configure.ac fixes the problem. After changing configure.ac you'll have to run autogen.sh again.

AC_CONFIG_MACRO_DIR is provided by autoconf, but it's a configuration I haven't tried so I don't know whether it will configure fine or not.

Upgrading automake is very easy: if you don't want to change the system-wide automake version, you can just install an upgraded one into your home directory and set your PATH accordingly when building fsw.

Cheers, -- Enrico

[muyinliu]

After upgrade automaker from 1.9.6 to 1.14.1, ./autogen.sh without any error or warning. But ./configure, it says: configure: error: *** A compiler with support for C++11 language features is required. It's that means my gcc 4.1.2 20080704 (Red Hat 4.1.2-54) is too old? Here is part of the messages while ./configure: checking dependency style of g++... gcc3 checking whether g++ supports C++11 features by default... no checking whether g++ supports C++11 features with -std=c++11... no checking whether g++ supports C++11 features with -std=c++0x... no configure: error: *\ A compiler with support for C++11 language features is required.

[emcrisostomo]

Yes @muyinliu, it means you need a recent C++ compiler. You can install the latest GCC or CLang compiler using the package manager of your distribution.
