Current ntop broken (and fails to rebuild) by current rrdtool

[gthb (Gunnlaugur Thor Briem)]

Port rev-upgrade is reporting ntop as broken and failing to rebuild it, because ntop references a lib that's no longer present in the current rrdtool.

You can always run 'port rev-upgrade' again to fix errors.

$ port installed rrdtool
The following ports are currently installed:
  rrdtool @1.5.5_1
  rrdtool @1.7.0_0 (active)

Indeed the current rrdtool doesn't contain that lib:

$ port contents rrdtool | grep _th

... outputs nothing.

Now if I activate the older version:

$ sudo port activate rrdtool @1.5.5_1
--->  Computing dependencies for rrdtool
--->  Deactivating rrdtool @1.7.0_0
--->  Cleaning rrdtool
--->  Activating rrdtool @1.5.5_1
--->  Cleaning rrdtool

then I do have that lib:

$ port contents rrdtool | grep _th
  /opt/local/lib/librrd_th.4.dylib
  /opt/local/lib/librrd_th.a
  /opt/local/lib/librrd_th.dylib

and the rev-upgrade no longer finds ntop broken:

sudo port -v rev-upgrade
--->  Scanning binaries for linking errors
--->  No broken files found.

So current MacPorts version of ntop is not compatible with current MacPorts version of rrdtool. Probably should explicitly depend on an older version, or be updated itself. (Or maybe the current rrdtool is just broken by not having that library; I don't know.)

main.log from the failing build

[mf2k (Frank Schima)]

looking at the ntop homepage, I don't see what the latest version of ntop is? Do you know?

[gthb (Gunnlaugur Thor Briem)]

I don't know for sure. But from the homepage it seems like ntop is a deprecated old codebase and the “modern” replacement is ntopng (ng probably meaning “next generation”).

Indeed the current ntop version in MacPorts is 5.0.1 and ​it appears that 5.0 was released in summer 2012. There is no ntopng in MacPorts.

[mf2k (Frank Schima)]

There is a submission ticket with a version of ntopng from 3 years ago. #39667. I think updating that to the latest version and adding to Macports is the best solution.

According to this mail thread

• ​https://lists.oetiker.ch/pipermail/rrd-developers/2016-March/004489.html

librrd_th has been deprecated as librrd is now thread safe.

Hi Paul

if you are looking at the master branch ... librrd_th is gone since librrd is now thread-safe

So what is the solution?

[nsk-dev]

Why do you keep this port although it is outdated and always failing to build?

ntopng native installer is already available for MacOS by the way. ​https://www.ntop.org/announce/introducing-ntopng-for-macos-finally/

It failed to start after installing the package:

~ % sudo ntopng

It susccessfully runs after the following steps:

sudo port install redis   
sudo redis-server /opt/local/etc/redis.conf
sudo ntopng &
http://localhost:3000
