[erlang-questions] dialyzer in R11B-4

[Ulf Wiger]

Dialyzer crashed while I was trying to build OTP R11B-4 on my ubuntu box.

I tried running ./configure ... --disable-dialyzer

This led to the following crash:

if test -f lib/dialyzer/SKIP ; then                     \
                echo "=== Skipping dialyzer, reason:" ;         \
                cat lib/dialyzer/SKIP ;                         \
                echo "===" ;                                    \
        else                                                    \
                cd lib/dialyzer &&                              \

                        make opt BUILD_ALL=true ;               \
        fi

The 'undef' error actually looks the same if I don't disable dialyzer, but I
would have
thought that disabling it meant that it would try to analyze the build! If
make
doesn't build dialyzer, the chances that it will succeed in analyzing the
results
seem rather slim.

When it crashed the first time, I verified that the dialyzer modules had in
fact
been built, so the crash looks like a path error. I'm using --prefix. Would
that
matter? Apologies for not doing any deeper analysis myself.
