[Bug 1772747] [NEW] Package is missing several dependencies

[Adam Novak]

Public bug reported:

libcurl4-gnutls-dev provides my /usr/bin/curl-config and the static
library (symlink) /usr/lib/x86_64-linux-gnu/libcurl.a -> libcurl-
gnutls.a. I am trying to link statically against that static library.

The right way to do this seems to be to run "curl-config --static-libs"
and forward the result along to my linker. But doing that causes the
linker to complain about several missing libraries.

The flags I get are:

-Wl,-Bstatic -lcurl -Wl,-Bdynamic -Wl,-Bsymbolic-functions -Wl,-z,relro
-Wl,-z,now -Wl,--as-needed -lnghttp2 -lidn2 -lrtmp -lpsl -lnettle
-lgnutls -llber -lldap -llber -lz

And the (unique) missing libraries are:

/usr/bin/x86_64-linux-gnu-ld: cannot find -lnghttp2
/usr/bin/x86_64-linux-gnu-ld: cannot find -lidn2
/usr/bin/x86_64-linux-gnu-ld: cannot find -lrtmp
/usr/bin/x86_64-linux-gnu-ld: cannot find -lpsl
/usr/bin/x86_64-linux-gnu-ld: cannot find -lnettle
/usr/bin/x86_64-linux-gnu-ld: cannot find -lgnutls
/usr/bin/x86_64-linux-gnu-ld: cannot find -llber
/usr/bin/x86_64-linux-gnu-ld: cannot find -lldap

So pretty much all the interesting libraries are missing.

The packages that provide these are:

libnghttp2-dev provides libnghttp2.a
libidn2-dev provides libidn2.a
librtmp-dev provides librtmp.a
libpsl-dev provides libpsl.a
nettle-dev provides libnettle.a
libgnutls28-dev (in Bionic) and other packages in older releases provide libgnutls.a
libldap2-dev provides liblber.a and libldap.a

All of these packages need to be dependencies of libcurl4-gnutls-dev, so
that libcurl.a can be used.
