Hello! I'm trying to debug a problem with one of the latest ports
(devel/t1lib). The port's maintainer, Ying-Chieh Liao, can not reproduce
it. The port does not do any patching, so a number of people used this
exact configure script with no troubles. I'm hoping a larger audience
can help me understand what's going on.
The configure script gets stuck, because one of the tests ("checking
whether external symbols need an underscore prefix") starts expecting
input from stdin, it seems. I first thought, it is related to my choice
of CFLAGS, but it behaves the same way even if I do not touch them.
Could I be running "just the right" version of stable? (FreeBSD
3.2-STABLE Tue Jun 8 12:46:07 EDT 1999 i386)... I first observed this
during the simple ``make install'' of the port, but the line that make
ends up executing:
env CC="cc" CXX="c++" CFLAGS="-O -pipe" CXXFLAGS="-O -pipe" \
INSTALL="/usr/bin/install -c -o root -g wheel" \
INSTALL_DATA="install -c -o root -g wheel -m 444" \
INSTALL_PROGRAM="install -c -s -o root -g wheel -m \
555" INSTALL_SCRIPT="install -c -o root -g wheel -m \
555" PORTOBJFORMAT=elf ./configure --prefix=/usr/local \
i386--freebsd3.2
hangs by itself.
Putting ``set -x'' in the middle of the configure script shows:
checking for gcc strength-reduce bug... no
checking whether external symbols need an underscore prefix... + echo ${ac_cv_c_extern_prefix+set}
+ eval test "${ac_cv_c_extern_prefix+set}" = set
+ test = set
+ saved_libs=
+ LIBS=conftest_asm.s
+ cat
+ cat
+ eval echo configure:2794: "${CC-cc} -o conftest $CFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS 1>&5"
+ echo configure:2794: cc -o conftest -O -pipe conftest.c conftest_asm.s 1>&5
[... HANG ...]
The list of processes in the terminal then appears as (some fields removed):
PID PPID WCHAN STAT TIME COMMAND
359 353 pause Is 0:00.71 -csh (tcsh)
22327 359 wait I+ 0:00.27 /bin/sh ./configure --prefix=/usr/local i386--freebsd3.2

Note, the ``ttyin'' state of the `as'... Any clues? Thanks!
