There seems to be a problem with autoconf generated scripts when running
the resulting configure on a text mount. I came across this when trying
to compile lame:
checking for int64_t... yes
configure: error: CHECK_TYPE_uint32_t - please report to lame-dev <at>
lists.sourceforge.net
I tracked this down to this line in configure:
FILE *f = fopen ("conftest.val", "w")
If I change all occurrences to
FILE *f = fopen ("conftest.val", "wb")
the configure and build succeeds.
I am not familar enough with autoconf to be able to tell how that line
gets into configure. I can't find it in configure.in. All I can see is
stuff like AH_VERBATIM([HAVE_UINT64_T] and AC_CHECK_TYPES([uint8_t,
int8_t, uint16_t, int16_t, uint32_t, int32_t, uint64_t, int64_t]); I'd
guess it is releated to the latter.
The contents of conftest.val are used later like
ac_cv_sizeof_unsigned_int=`cat conftest.val`
which adds a \r to the assignment causing later tests like
if test "${ac_cv_sizeof_unsigned_int}" = "4"; then
...
to fail.
Running autoconf on cygwin results in the same broken configure script.
Any ideas what should be done other than not using a text mount? To me
opening the conftest.val file as text is wrong.
