Hi,
I have a problem with the combination of
- GNU bash, version 2.05.0(6)-release (i686-pc-cygwin)
- autoconf (GNU Autoconf) 2.52
on W2K.
DOS CR/LF line ends in the parameter passed to AC_OUTPUT cause
config.status to fail.
We have a macro AC_FINISH which internally uses AC_OUTPUT:
dnl --------------------------------------------------------------------
--
dnl Restore CFLAGS, filter duplicate entries from LIBS
dnl --------------------------------------------------------------------
--
AC_DEFUN([AC_FINISH],
[CFLAGS="$CFLAGS_SAVE"
LIB_LIST="" && for i in $LIBS; do case "$LIB_LIST" in *"$i") ;; *"$i "*)
;; *) LIB_LIST="$LIB_LIST $i"; ;; esac; done
LIBS=$LIB_LIST]
[AC_OUTPUT($1)]
)
A typical use case in 'configure.in' is:
AC_FINISH(config/Make.rules:config/Make.rules.in:../config/Make.rules.in
Makefile \
include/Makefile \
include/JTCC/Makefile \
src/Makefile test/Makefile \
demo/Makefile)
If a parameter passed to AC_OUTPUT contains DOS CR/LF line endings in a
'configure.in' file (e.g. at places (1) then the output generated in
'config.status' "preserves" the line endings as '^M' which makes the
approriate run fail.
If a '\' is followed by a CR/LF, then this '\' arrives unmodified in
'config.status'.
AC_FINISH(config/Make.rules:config/Make.rules.in:../config/Make.rules.in
Makefile \0x0a
include/Makefile \0x0a
include/JTCC/Makefile 0x0d 0x0a
^(1)
src/Makefile test/Makefile \0x0d 0x0a
^(2)
demo/Makefile)
The resulting output in config.status with the above example is:
config_files="
config/Make.rules:config/Make.rules.in:../config/Make.rules.in Makefile
include/Makefile include/JTCC/Makefile \^M src/Makefile ^M
^(3) ^(4)
test/Makefile demo/Makefile"
The result of this is:
-----------------------------------------------------
...
cd .; ./config.status
config.status: creating config/Make.rules
config.status: creating Makefile
config.status: creating include/Makefile
config.status: creating include/JTCC/Makefile
config.status: creating \
^(5) corrsponds to (3) above.
.infig.status: error: cannot find input file: \
make: *** [Makefile] Error 1
-----------------------------------------------------
According to the autoconf doc., the shell interpretes the parameter
passed to AC_OUTPUT.
Best regards,
Manfred
