Topic: Pianoteq 8 = Way to much hassle to upgrade if problems occur.

I cannot log into the Pianoteq user area on the computer that has been running Pianoteq since version 5.   The computer is connected to the internet, and other sites do work.   There is some sort of manual activation which is very complicated and requires many complicated steps.   I'm 80 years old and I'm honestly overwhelmed by the complexity. I feel very frustrated.  It does not make sense that a computer that works with the Internet in general cannot log onto the Pianoteq user area any longer.

I think you could best contact Modartt support. I've got good experiences with their assistance.

Same issue with accessing my account to upgrade from 7 8 even after getting my password changed. (That worked) Awaiting response from support.  NB to Modarrt. Sent email to Niclas on Nov 20th.  I agree with MrRoland that Modarrt support is very good.

They say they are going to work with me.   Does anyone know exactly how you launch Pianoteq from the Linux terminal?   I can only do it by clicking on the executable in the file manager.   That's with 7.5.4 and 8.x, however 8.x doesn't run.   Neither one launch from the terminal.   There's not much output from the terminal, at least nothing that points to a direction to go.  Mostly it just doesn't work.

Re: Pianoteq 8 = Way to much hassle to upgrade if problems occur.

Usually Pianoteq is installed in your HOME-directory. Then you can open a terminal window on your desktop and type the command:

./Pianoteq\ 8/x86-64bit/Pianoteq\ 8

Alternatively the full path, if known, for example:

/home/GRB/Pianoteq\ 8/x86-64bit/Pianoteq\ 8

Watch the error messages in that terminal, if something goes wrong.

Thanks.  I found out that to launch a program in Linux from the terminal you have to put "./" without the quotes, simply ./

Any way there's a shared library that it cannot access.

That looks like a bug, which might be caused by a mismatch between your Linux and what Modartt used to compile Pianoteq. I'm still using v7 so I have not tried this myself yet, but if you are still experiencing it, and if you are using a Linux that is not too old and not too new, I suggest you contact them for a bug report since they may well miss your post here among a gazillion of others. Just paste the above into the form at https://www.modartt.com/support

Re: Pianoteq 8 = Way to much hassle to upgrade if problems occur.

The most generic way to install Pianoteq I know is to just unzip the downloaded archive in the HOME directory:

p7zip -d pianoteq_linux_v802.7z

The unpacked default path of the startable binary (with all those ugly blanks) then is:

./Pianoteq\ 8/x86-64bit/Pianoteq\ 8

The shared library libmvec.so.1 is in the installed Debian package libc6, which should exist on a Kubuntu too. Check as root:

# dpkg -l libc6
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version         Architecture Description
+++-==============-===============-============-=================================
ii  libc6:amd64    2.31-13+deb11u5 amd64        GNU C Library: Shared libraries


Check, which libmvec is contained in your libc6, example on my system:

# dpkg -L libc6 | grep libmvec
/lib/x86_64-linux-gnu/libmvec-2.31.so
/lib/x86_64-linux-gnu/libmvec.so.1

Note that libmvec.so.1 is just a symbolic link to the actual version libmvec-2.31.so.

Re: Pianoteq 8 = Way to much hassle to upgrade if problems occur.

i confirmed on my system (rather old version of Ubuntu, actually 16.04 ... i know i know, very embarrassing) that Pianoteq v 7.5.4 is not looking for libmvec.so whereas Pianoteq 8 is.  but since my system is so ancient and it works (libmvec is there), undoubtedly you'll be able to install this missing dependency and it will work, no problem.

With Pianoteq 7 the output of lsof (list open files) is empty.

Perhaps PTQ7 was statically linked and PTQ8 dynamically linked to shared libraries? You can investigate if that is the case with ldd and nm.

Re: Pianoteq 8 = Way to much hassle to upgrade if problems occur.

Pianoteq 7 was built on ubuntu 16.04 , while Pianoteq 8 is now built on ubuntu 18.04. This change was required because our tooling needs more modern features. The libmvec, which is part of glibc (so it is a very low level part of the linux system), was introduced between ubuntu 14.04 and ubuntu 16.04.
