MacPorts and Myth 0.28

[pvr4me]

Greetings,

I was having difficulty running the migration process

Code: Select all

https://trac.macports.org/wiki/Migration

so I decided to build from a clean ports perspective.

1) sudo port -f uninstall installed
2) sudo port install mythtv-core.28 +mariadb+mariadb55+python27+perl5_24

I looped through 1 & 2 above and I got the following error:

Code: Select all

:debug:archivefetch Error code: NONE
:debug:archivefetch Backtrace: logrotate must be installed with +startupitem.

I tried a workaround ..

1) sudo port clean logrotate
2) sudo port install logrotate +gzip+startupitem
I noticed that it had a broken link but was able to build

OK, this was the right thing to do.

3) sudo port install mythtv-core.28

This went through the build process unsuccessfully

Code: Select all

Any ideas?

I was able to build mythtv 0.28 on my iMac through the migration process (but had problems with unrelated ports that I just cleaned up manually) but I can't seem to build from a clean ports perspective on my mac mini.

Remind me again, this is occurring under Sierra? XCode 8? Command Line Tools are installed?

The log message is clear that it is throwing an error on mythwikiscripts but nothing has changed from the Myth side. I can work around this easily enough, but I don't have a Sierra/XCode 8 environment yet.

Sierra with Xcode 8 and Command line tools installed. I will verify Xcode8 and command line tools. Sometimes I get the pointed to a beta version.

I confirmed Sierra, Xcode 8 and command line tools are installed.

Here is a snippet of the debug log referred below

...

Could you please clean mythtv-core.28 and try the install again. (Glitches do happen!) I'll try to find some time to get a Sierra build environment up and running if you confirm that it fails in the same spot.

I verified that I have Sierra, Xcode 8 and the command line tools installed

Last night, I did the following to confirm that it happened again.

Code: Select all

1) sudo port -f uninstall installed
2) sudo rm -rf /opt/local/var/macports/build/*
3) sudo port install logrotate +gzip+startupitem     
4)  sudo port install mythtv-core.28 +mariadb+mariadb55+python27+perl5_24

I didn't notice any unusual or specific problems with the other ports.


I got the same error message that I posted previously.

I was able to build other ports such as ffmpeg successfully...


note:
I can't explain why my iMAC was successful with the build for mythtv-core.28 but I used the migration process and then went and fixed various ports that failed and eventually got it to work.

BTW: Do you establish the Sierra environment within a VM like Parallels or VMWare Fusion ?

...

Yes, I use Parallels to build and test with different MacOS versions.

Anyway after hours fighting with Parallels and then creating a new VM from scratch, I was able to recreate the problem on Sierra. Seems strange that it fails there and works on earlier versions. Anyway, the fix was quite simple and I've committed it to MacPorts. After a half hour from now, you should be able to selfupdate and finish the install.

And I suspect it will then work for you. Here's hoping at least!

THANK YOU for your quick response and hard work getting the VM environment up for Sierra so that you could fix the problem.

I was able to run selfupdate and build up mythtv 0.28 and mythweb 0.28 with the fix in Sierra.

I am going to run through part of the migration process to start from a "clean state" and rebuild back up again tomorrow morning.

Then, I will start testing under Sierra.

Any feedback on how it is going in Sierra?

Any feedback on how it is going in Sierra?

I still don't have a Sierra environment set up. My work on the port for 0.28 got derailed. I need some supporting changes done to the MariaDB port and the maintainer of that port has essentially disappeared. And another project is now consuming all my time. I hope to get back to Myth in the next couple of weeks but no promises.

I apologize for the delays. Hopefully it will be worth it in the end.

Craig
(And 0.27 still works fine!)

[sfatula]

Sorry Craig, I was speaking to gsulshski as you had made the change and he was able to build it. Wondering how it is working for him.

[gsulshski]

I had trouble accessing the website and forum for a while and didn't make any immediate feedback.

1) I followed the migration path

Code: Select all

Uninstall all installed ports:
sudo port -f uninstall installed

Clean any partially-completed builds:
sudo rm -rf /opt/local/var/macports/build/*

2) then I installed mythtv 0.28

Code: Select all

   sudo port install logrotate +gzip+startupitem 
             sudo port install mythtv-core.28 +mariadb+mariadb55+python27+perl5_24
             sudo port install mariadb-server

3) Then I installed mythweb 0.28

Code: Select all

  sudo port install mythweb.28 

I didn't get any macports build errors.


From a testing feedback,

I don't have any issues using my two Kodi frontends to work with Mythtv.

Mythtv frontend doesn't work right for me on the mac mini where I have the backend installed as well.

When I run LiveTV the first time, I can watch a Live TV station but if I exit out and comeback in or if I try to jump to another channel I get the following:
"jump program file buffer error". After that , I will always get this error message.

I haven't the time to do any significant debug but I did do a verbose run mythfrontend -v ....but I ran out of time looking at it. I did look at the frontend and backend logs and saw some errors.

The only time that I use mythtvfrontend is when I do a faux PIP with my Kodi in full screen when watching more than 1 sports program.

On the other hand, Mythtv frontend on my iMac works fine.

Also, I still have the mythweb problems that I have stated before where it works and then errors.

I started to do some debug in apache and then again ran out of time. I can at least use myth Webfrontend for the moment.

Code: Select all

Net: 1) mythtv 0.28 built fine this time
        2) myth_frontend works on a remote machine but fails with "jump program file buffer error" on the machine where the backend resides
        3) Mythweb 0.28 gets Fatal error: Call to a member function query_col() on a non-object in /opt/local/apache2/htdocs/MythWeb/modules/backend_log/init.php on line 15
        4)  Kodi frontends work locally and remotely flawlessly with mythtv  (mac mini, iMac and firetv)

I wonder if I should retry the build from scratch and then debug or just debug it now.

BTW, I presume you did 'sudo port selfupdate' before reinstalling Myth. That makes sure you are using the most recent versions of the packages.

Re rebuilding, I highly doubt there will be any difference. If the build finished successfully the first time, you are very likely to get exactly the same result on subsequent builds. More likely, one (or several) of the 140 dependencies that Myth relies on [1] will have been updated in the interim. So we'll have a moving target where differences might be caused by updates to those packages!

Re the jump buffer error. If I understand correctly, you can reliably reproduce this error, right? If so, the logs are key. Please stop and restart Myth, reproduce the error and then post back and frontend logs. Hopefully that will lead us in the right direction.

Re MythWeb, I think this is likely a configuration issue but I don't know specifically. There are people that make a good career out of getting MySQL, Apache and PHP to play nicely together. I'm not one of them.

Craig
[1] Those are runtime dependencies only. I don't know how many more there are at build time!

Just an FYI - I had the same problem, just today, with Myth 0.28, under Sierra, empty Macports (downloaded and updated but no packages installed). Install myth base, and, logrotate failed due to missing startupitem variant. Had to do the same workaround.

I am now on Sierra, but thus far, no issues with Mythweb, seems to work for me as it always did. Mythfrontend also works as much as has been coded there.

I guess I should have been more clear: logrotate is not "failing". Myth needs it installed with the startupitem variant enabled--the only way to indicate that it is missing is to throw an error.

The install command needs to be:

Code: Select all

sudo port install mythtv-core.28 +mariadb+mariadb55+python27+perl5_24+startupitem

Note the '+startupitem' on the end. This gets passed through when installing logrotate and then all will proceed normally.

Glad to hear that it is working for you. After about a month of dealing with family issues, I hope that I may have a little time to work on Myth again.

Craig
(Please let me know if there are docs out there that are missing the +startupitem bit.)
