Package: dpkg-dev
Version: 1.14.12
Severity: normal
Hi,
it looks like dpkg-dev (or symbol stuff) is missing some symbols. While
building libpano13 (pkg-phototools/libpano.git on git.d.o, in the
libpano13/unstable branch, uscan is your friend), I've got:
$ grep 'found in none of the libraries' ../libpano13_2.9.12-1_i386.build
dpkg-shlibdeps: warning: symbol exp used by
debian/libpano13-0/usr/lib/libpano13.so.0.0.0 found in none of the libraries.
dpkg-shlibdeps: warning: symbol hypot used by

Looks like libm, right? Let's check:
$ for i in `grep 'found in none of the libraries'
../libpano13_2.9.12-1_i386.build | awk '{print $4}'`; do nm -D /usr/lib/libm.so
| cut -b 10- | grep "^W $i$" ; done
W exp
W hypot
W atan2
W atan
W asin
W atanh
W log
W pow
W ceil
W floor
I'm not that willing to dig it out how you gather symbol information,
but it really looks like you're missing something here.
And that's AFAICT not a duplicate of #454036, I'll be following up there
in some minutes.
Cheers,

Looks like libm is really missing ...

Here it looks like dpkg-shlibdeps is right. :-)
