Bug in autoconf 2.53

[Jens Krüger]

Hi,

it takes me a long time to find the following bug. I used the following 
configure.in:

AC_INIT(TestFilterClass, 0.0.0, address@hidden)
AC_PREREQ(2.52)
AC_COPYRIGHT([(c) Jens Krüger])
AC_CONFIG_SRCDIR(main.cpp)
AC_CONFIG_AUX_DIR(config)
AM_INIT_AUTOMAKE([1.6])

AM_PROG_LIBTOOL
AC_PROG_CXX
AC_ISC_POSIX

AM_CONFIG_HEADER(config.h)

AM_PROG_LIBTOOL
AC_STDC_HEADERS

AC_PROG_MAKE_SET

CXXFLAGS="$CXX_FLAGS -g -Wall -D_REENTRANT -D_GNU_SOURCE"
AC_SUBST(CFLAGS)

QTDIR=${QTDIR-/usr/local/qt}
AC_SUBST(QTDIR)
MOC=${QTDIR}/bin/moc
AC_SUBST(MOC)

UIC=${QTDIR)/bin/uic
AC_SUBST(UIC)

AC_PREFIX_DEFAULT(${DAVEROOT-/usr/local})

NEXUSROOT=${NEXUSROOT-/usr/local/NeXus}
AC_SUBST(NEXUSROOT)

HDFROOT=${HDFROOT-/usr/local/hdf}
AC_SUBST(HDFROOT)

imagedir=${DAVEROOT-/usr/local}"/share/openDaVE"
AC_SUBST(imagedir)

AC_ARG_ENABLE(debug, [  --enable-debug        enable debug output of the 
modules default=no],
                [CXXFLAGS="$CXXFLAGS -D_DEBUG"], [])

AC_CONFIG_FILES(Makefile)
AC_OUTPUT

running the following commands:

touch ChangeLog
touch NEWS
aclocal -I config
autoheader
libtoolize --force --copy --automake
automake --add-missing --copy --include-deps 
autoconf

running configure I got the following output:

./configure: line 8039: `     s/^\([^=]*\)=\(.*[{}].*\)$/test "${\1+set}" = 
set || &/'

I could not understand what's the reason for this mysterious message. After a 
lot of hours I found the reason:

Instead of 

UIC=${QTDIR}/bin/uic

I wrote

UIC=${QTDIR)/bin/uic

I guess this bug is very difficult to find and occur rarly, but it should be 
fixed in one of the next releases.

Jens
