libtasn1 no longer provides libtasn1-config, let's provide one until depending packages are fixed

[bugs@…]

See [41968] and #17197 for examples where this is causing problems. Since it will take some time to find all the broken packages and make them not broken, perhaps the following script should be installed into /opt/local/bin/libtasn1-config and set executable as part of the libtasn1 installation:

#!/bin/bash

if [[ $1 == "--libs" ]]; then
        echo "-L/opt/local/lib -ltasn1"
fi
if [[ $1 == "--cflags" ]]; then
        echo "-I/opt/local/include"
fi
if [[ $1 == "--version" ]]; then
        echo "1.6"
fi

This will allow things to work until ports get tracked down and updated.

Here's a better version I didn't test as well that should respect people's prefixes:

#!/bin/bash
PREFIX=`cat /opt/local/etc/macports/macports.conf | grep ^prefix | cut -f 2- | xargs -n 1 echo`

if [[ $1 == "--libs" ]]; then
        echo "-L${PREFIX}/lib -ltasn1"
fi
if [[ $1 == "--cflags" ]]; then
        echo "-I${PREFIX}/include"
fi
if [[ $1 == "--version" ]]; then
        echo "1.6"
fi

Actually this one is substantially better as it will try and find the actual configuration file instead of just assuming it's at the standard prefix. The advantage to this being that we can actually try and actually respect prefixes instead of just pretending to. :)

#!/bin/bash
IFS=":"
for dir in $PATH; do
if [ -e `echo ${dir}/etc/macports/macports.conf | sed s/\\\/bin//` ]; then
CONF=`echo ${dir}/etc/macports/macports.conf | sed s/\\\/bin//`
fi
done
if [ ! -e ${CONF} ]; then
echo "No configuration for macports found"
exit
fi
PREFIX=`cat ${CONF} | grep ^prefix | cut -f 2- | xargs -n 1 echo`

if [[ $1 == "--libs" ]]; then
echo "-L${PREFIX}/lib -ltasn1"
fi
if [[ $1 == "--cflags" ]]; then
echo "-I${PREFIX}/include"
fi
if [[ $1 == "--version" ]]; then
echo "1.6"
fi

Why not use pkg-config in the script? Then there's no need to jump through hoops or hardcode values.

That sounds like exactly what should be done... as for why I didn't do it, well, didn't really know about it. :)

#!/bin/bash
if [[ $1 == "--libs" ]]; then
echo `pkg-config --libs libtasn1`
fi
if [[ $1 == "--cflags" ]]; then
echo `pkg-config --cflags libtasn1`
fi
if [[ $1 == "--version" ]]; then
echo `pkg-config --version libtasn1`
fi

Better?

Or even

#!/bin/bash
${prefix}/bin/pkg-config $1 libtasn1

[jmr@…]

But is pkg-config --version different to libtasn1-config --version? Might need to translate --version to --modversion.

I fixed gnome-keyring using the patch from ​http://bugzilla.gnome.org/show_bug.cgi?id=560869 in r42286. Are there any other ports that need libtasn1-config?

[devans@…]

Additional ports that depend on libtasn1 are:

irc/bitlbee
mail/msmtp
net/gloox
security/libprelude
sysutils/ntfsprogs
textproc/iksemel                  

Ccing maintainers of msmtp and libprelude. Rest are nomaintainer.

None of these use libtasn1-config but rather use libgnutls-config and gnutls was fixed in r41968. The dependency on libtasn1 in these files is therefore superfluous -- a dependency on gnutls is sufficient.

Are there any ports remaining that would need this, or should we close this?

Assuming this isn't a problem any more based on lack of response to comment:13.
