Hello,
I'm relatively new to autoconf, and I'm having trouble getting the
configure file to generate properly on another person's computer. It
appears that when he uses the AC_ERLANG_CHECK_LIB macro, the configure
file that's generated has an AC_ECHO still embedded in one of the
strings to be called. To recreate the problem, we made a skeleton
configure.ac containing only:
AC_INIT
AC_ERLANG_CHECK_LIB(erl_interface)
When my friend runs autoconf on the file, the relevant section (at
least, I think this is where the problem lies) reads:
{ $as_echo "$as_me:$LINENO: checking for Erlang/OTP 'erl_interface'
library subdirectory" >&5
$as_echo_n "checking for Erlang/OTP 'erl_interface' library
subdirectory... " >&6; }
if test "${erlang_cv_lib_dir_erl_interface+set}" = set; then
$as_echo_n "(cached) " >&6
else
ac_ext=erl
ac_compile='$ERLC $ERLCFLAGS -b beam conftest.$ac_ext >&5'
ac_link='$ERLC $ERLCFLAGS -b beam conftest.$ac_ext >&5 ; echo "#!/bin/
sh" > conftest$ac_exeext ; AS_ECHO(["\"$ERL\" -run conftest start -run
init stop -noshell"]) >> conftest$ac_exeext ; chmod +x conftest
$ac_exeext'
if test "$cross_compiling" = yes; then
{ { $as_echo "$as_me:$LINENO: error: cannot run test program while
cross compiling
See \`config.log' for more details." >&5
$as_echo "$as_me: error: cannot run test program while cross compiling
See \`config.log' for more details." >&2;}
{ (exit 1); exit 1; }; }
else
And when I run it, it reads:
{ echo "$as_me:$LINENO: checking for Erlang/OTP 'erl_interface'
library subdirectory" >&5
echo $ECHO_N "checking for Erlang/OTP 'erl_interface' library
subdirectory... $ECHO_C" >&6; }
if test "${erlang_cv_lib_dir_erl_interface+set}" = set; then
echo $ECHO_N "(cached) $ECHO_C" >&6
else
ac_ext=erl
ac_compile='$ERLC $ERLCFLAGS -b beam conftest.$ac_ext >&5'
ac_link='$ERLC $ERLCFLAGS -b beam conftest.$ac_ext >&5 ; echo "#!/bin/
sh" > conftest$ac_exeext ; echo "\"$ERL\" -run conftest start -run
init stop -noshell" >> conftest$ac_exeext ; chmod +x conftest$ac_exeext'
if test "$cross_compiling" = yes; then
{ { echo "$as_me:$LINENO: error: cannot run test program while
cross compiling
See \`config.log' for more details." >&5
echo "$as_me: error: cannot run test program while cross compiling
See \`config.log' for more details." >&2;}
{ (exit 1); exit 1; }; }
else
Now, I did note that his has $as_echo wherever mine had just echo, and
I don't know why that is, and don't know why google couldn't provide
any useful links on the matter. The real problem appears to be that
his "ac_link" variable has AS_ECHO in it instead of echo, which seems
like it would cause problems to me. This is where he gets an error
when running ./configure:
./configure: eval: line 1: syntax error near unexpected token `["\"$ERL
\" -run conftest start -run init stop -noshell"]'
./configure: eval: line 1: `$ERLC $ERLCFLAGS -b beam conftest.$ac_ext
>&5 ; echo "#!/bin/sh" > conftest$ac_exeext ; AS_ECHO(["\"$ERL\" -run
conftest start -run init stop -noshell"]) >> conftest$ac_exeext ;
chmod +x conftest$ac_exeext'
For the record, I am using autoconf 2.60 and M4 version 1.4.5, and he
is using autoconf 2.62 and M4 version 1.4.11. My platform is Mac OS X
10.5 running fink versions of these tools and he is using Mac OS X
10.4 running the darwinports version, if that makes any difference.
Do any of you know what might be happening here, and what my next
troubleshooting steps should be?
Thanks.
