libgnutls missing package configuration (PC) files

[Jeffrey Walton]

* Not a security vulnerability *

libgnutls appears to be missing its package configuration file, or the configuration file is not available.

During causal reading of the GnuTLS online manual, section 7.1.5, Building the Sources, the manual states the following can be used to compile a program with the same settings used by the library. It seemed like a neat feature, so I wanted to try it.

    gcc -c foo.c `pkg-config gnutls --cflags`

Unfortunately, it appears the PC file is missing or unavailable on Ubuntu 10.04 (x64):

    $ uname -a
    Linux 2.6.32-25-generic #45-Ubuntu SMP Sat Oct 16 19:52:42 UTC 2010
    x86_64 GNU/Linux

    $ pkg-config gnutls --cflags
    Package gnutls was not found in the pkg-config search path.
    Perhaps you should add the directory containing `gnutls.pc'
    to the PKG_CONFIG_PATH environment variable
    No package 'gnutls' found

    $ apt-cache pkgnames | grep libgnutls | sort
    libgnutls11-dev
    libgnutls13-dbg
    libgnutls26
    libgnutls26-dbg
    libgnutls5-dev
    libgnutls-dev

    $ pkg-config libgnutls26 --cflags
    Package libgnutls26 was not found in the pkg-config search path.
    Perhaps you should add the directory containing `libgnutls26.pc'
    to the PKG_CONFIG_PATH environment variable
    No package 'libgnutls26' found

    $ ls /usr/lib/pkgconfig/*gnutls*
    ls: cannot access /usr/lib/pkgconfig/*gnutls*:
    No such file or directory

Description: the GNU TLS library - runtime library
 gnutls is a portable library which implements the Transport Layer
 Security (TLS) 1.0 and Secure Sockets Layer (SSL) 3.0 protocols.
 .
 Currently gnutls implements:
  - the TLS 1.0 and SSL 3.0 protocols, without any US-export
    controlled algorithms
  - X509 Public Key Infrastructure (with several limitations).
  - SRP for TLS authentication.
  - TLS Extension mechanism
 .
 This package contains the runtime libraries.

It appears the only two GnuTLS related configuration files reside in local directories. from building the library from source.

$ find / -name *.pc 2>/dev/null | grep gnutls
/home/jeffrey/Desktop/gnutls-2.10.3/lib/gnutls.pc
/home/jeffrey/Desktop/gnutls-2.10.3/libextra/gnutls-extra.pc

$ ls /usr/lib | wc

Status changed to 'Confirmed' because the bug affects multiple users.

Bug still present in Ubuntu 13.10, apt-file search gnutls.pc returns nothing, when building e.g. rsyslog configure fails:

configure:17927: $PKG_CONFIG --exists --print-errors "gnutls >= 1.4.0"
Package gnutls was not found in the pkg-config search path.
Perhaps you should add the directory containing `gnutls.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gnutls' found

Seems like it should be pretty simple to add it to the package since per previous comments the file gnutls.pc is actually generated, just not part of the package.

This hasn't been commented on in a while, but I believe this is affecting my ability to compile libfilezilla-0.19.3 properly. I receive the message:

checking for gnutls >= 3.5.7... no
configure: error: GnuTLS 3.5.7 or greater was not found. You can get it from https://gnutls.org/

More detailed logs say:

configure:18612: checking for gnutls >= 3.5.7
configure:18619: $PKG_CONFIG --exists --print-errors "gnutls >= 3.5.7"
Package gnutls was not found in the pkg-config search path.
Perhaps you should add the directory containing `gnutls.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gnutls' found
configure:18622: $? = 1
configure:18636: $PKG_CONFIG --exists --print-errors "gnutls >= 3.5.7"

Thanks for the work keeping this up!

ps. I am using Ubuntu 18.04.3 LTS with the latest updates.

You need to install the libgnutls28-dev package to get the package configuration files.
