Online MacPorts Meeting on 21st April at 13:00 UTC

[Mojca Miklavec]

Hi,

I would like to announce the first online MacPorts meeting happening
two weeks from now, on April 21st at 13:00 - 14:00 UTC (if it takes
much longer than one hour, we are probably doing something wrong).

Many people wanted to join us at the face-to-face meeting last month,
but could not make it, or it was too expensive to travel or ...

This meeting gives you the opportunity to get involved into a lively
discussion about MacPorts future. Some potential topics could be:
- quick overview of the meeting in Slovenia
- plans for MacPorts release(s)
- website-related topics
but I would like to open the discussion now to suggest other more
important topics for this or one of the following meetings (if we end
up with too many proposals, we'll just organize another meeting to
keep this one reasonably short).

We should ideally have an agenda ready two days before the meeting, so
feel free to come up with proposals, specific questions etc.

Suggestions for the best platform to use are also welcome. IRC is
definitely one option, but some might prefer a combination of voice +
chat? I don't expect there would be a prohibitive number of people
participating for a voice conference.

See you all in two weeks,
Mojca

Re: Online MacPorts Meeting on 21st April at 13:00 UTC - suggestion

[William H. Magill]

IRC is still quite popular in Europe, but is little used in the US.

One alternative to IRC is “Discord” — it has the same “type text” capabilities 
as IRC, but as far as I’m concerned, it is MUCH easier to use.
It also supports voice channels.

And, yes, there is a Mac client - OSX and IOS - as well as access through the 
browser.

https://discordapp.com

It is pitched as “for gamers,” mainly because of its voice capabilities.

OpenModelica?

[Murray Eisenberg]

I’m trying to install the port of OpenModelica. The instructions at 
https://www.openmodelica.org/download/download-mac 
 give, as first step:

echo rsync://build-openmodelica.org/macports/ >> 
/opt/local/etc/macports/sources.conf

But even with sudo, I’m getting a "Permission denied" error. 

How to fix this?

Re: OpenModelica?

[David Herron]

It's because the stdout redirect is executing as your user ID, and this has
nothing to do with MacPorts

The solution is to first do:

sudo su -

This gets you to a full root shell.  Then you do the command you said.

Re: OpenModelica?

[Murray Eisenberg]

Thanks, that seems to have worked.

To do the remaining steps…

port selfupdate
port install gcc44 # With the addition of llvm/clang as the default compiler in 
XCode, many ports now fail to build unless you force GCC to be used
port install openmodelica-devel +libraries +clang 
…should I still stay in that root shell?

It does say in their instructions, before those commands, "run (as root):"

You will need to be root to selfupdate and install ports, but usually you 
should do that by putting "sudo" in front of those commands.

It's unfortunate they're suggesting you should install an obsolete port like 
gcc44. The last version of gcc44 was released 6 years ago and we don't support 
it on High Sierra and later. The current stable version of gcc is gcc7.

Re: OpenModelica?

[Ken Cunningham]

sounds like this software needs a port and a maintainer!

It already has a port, and a collection of hundreds of related ports, in an 
entirely separate ports collection that the user must load into MacPorts in 
order to use. The previous messages in this thread describe Murray's attempts 
to do so on his system. I don't know why the developers of openmodelica have 
chosen to distribute their software in this way, rather than submit their 
portfiles for inclusion in the standard ports repository like everyone else 
does.

Ah. I see from Trac tickets this goes back a decade or more.

I’ve been using this port for a long time successfully.  It is a good project.  
They have tended to be responsive and helpful when issues on the Mac version 
have come up.
My impression of why they continue to operate this way is probably due to two 
things:  1)  Inertia…it’s the way that they have always done it.  2)  the 
openmodelica-devel port is auto generated because it links to the source files 
that change several times per day in their development repository.  They do 
also have separate ports for openmodelica and openmodelica-release that don’t 
change close to as often.

My guess is they would be fine with having a port created and maintained within 
macports, but they just don’t have the interested in doing it themselves, as 
they have a system that works.

The current version of openmodelica doesn’t need, or use, gcc44 and the +clang 
variant is also not required.  I think that they have just not updated the mac 
instructions in a long time.  Currently, all that should be required to install 
openmodelica-devel is adding the repository to macports, then doing:

sudo port install openmodelica-devel +libraries

(and even +libraries is not necessary, but adds a number of useful libraries)

Re: OpenModelica?

[Murray Eisenberg]

What’s happening now is befuddling to me. Doing the step 

   echo rsync://build.openmodelica.org/macports/ >> 
/opt/local/etc/macports/sources.conf

as root (sudo su - ) seems to have worked, as 
/opt/local/etc/macports/sources.conf now ends with:

   rsync://rsync.macports.org/release/tarballs/ports.tar [default]
   rsync://build-openmodelica.org/macports/

However, continuing as root, doing the step  

port selfupdate

gives:

Error: Synchronization of the local ports tree failed doing rsync

Could there be some issue with MacPorts access to the openmodelica repository?

Using rsync is completely new to me, and I don’t even know how to find out 
whether a particular source exists.

Use the -v flag to get more information about why it failed:

sudo port -v selfupdate

Re: OpenModelica?

[Murray Eisenberg]

The verbose flag on selfupdate shows that rsync-ing 
rsync.macports.org/release/tarballs/ports.tar is OK, but then...

Well it should be build.openmodelica.org not build-openmodelica.org.

Re: OpenModelica?

[Adam Dershowitz]

Did you mistype the echo command? 
The rsync says build DOT openmodelica.org
while the error shows
build HYPHEN openmodelca.org

and sure enough, using the proper name

build.openmodelica.org 

works just fine.

Re: OpenModelica?

[Murray Eisenberg]

Ouch, yes, my disastrous typo in the repository name, sorry. (The first time I 
tried, without using "sudo su -“, I had copied the “echo rsync” command

having to acquire the expensive Wolfram SystemModeler.)

I’m not sure why you would go to Mathematic, as you can simulate them just fine 
in OpenModelica, if you want.

there may be some hiccups in this software yet to be discovered

I note it tries to link to both -stdlib=libc++ and -stdlib=libstdc++ on the 
link line, and that just can’t be good…

Using any of the compiler variants provided is probably just wrong — if you 
want /usr/bin/clang++ don’t use any of the them, it appears. The clang variant 
gives you macports-clang-3.8.

Also, installing both gcc5 and gcc7 and libgcc6 and libgcc just seems nutty, so 
I added gcc6 and gcc7 to the fortran variants — but that has nothing to do with 
the above.

There are advantages to having your ports in the main repo, and having all of 
us look them over.

I know that a long time back, the default set of compilers didn’t work with 
OpenModelica, but that for a few years at least, the default set of variants 
has worked fine for building and using it.  Those instructions have probably 
just not been updated in a long time.  

I don’t know about the link issue, but I haven’t yet seen any problem caused by 
it….so far (in years of use)

Indeed, a major hiccup in the installation (which I did _without_ using the 
+clang variant).

Would it be appropriate to open a ticket http://trac.macports.org? 
 (I will post to the forum at openmodeler.org

And, for me it builds and installs just fine with the existing port file, and 
with the default variants:
sudo port install openmodelica-devel
(optionally adding +libraries to download the separate set of modelica 
libraries to use in openmodelica)

Re: OpenModelica?

[Murray Eisenberg]

OK, I made those edits to the portfile. I’m going to be using:

   sudo port install openmodeler +libraries

Anything I should uninstall before cleaning everything and then trying that 
install?

I’m trying to install the port of OpenModelica. The instructions at

But even with sudo, I’m getting a "Permission denied" error.

How to fix this?


I know I'm for offering a solution to you for this one case, but it can
be done with 'sudo' with a trick.  The 'sudo' command, by design, does
not allow you to directly redirect output to a file.  It's a (minimal)
security feature, to prevent people from using sudo that is more locked
down to certain commands from being able to use sudo to modify files
they might otherwise not have permission to...

The workaround is to use the 'tee' command:

echo rsync://build-openmodelica.org/macports/ | sudo tee -a 
/opt/local/etc/macports/sources.conf

The 'echo' will be sent to your screen as well as appended to the
designated file via the 'tee'.  The '-a' flag tells it to append, which
is what your '>>' in the original command would have done.

Using both gcc5 and gcc7 in a single port would indeed be nutty, if indeed they 
are doing that. Using gcc5 in one port and gcc7 in a different port is 
acceptable, though not ideal.

gcc6 and earlier require both libgcc6 and libgcc. This is normal. Just as gcc45 
and earlier require libgcc45, libgcc6, and libgcc. libgcc provides the current 
stable version of all the gcc libraries, currently those of gcc7. libgcc6 
provides the versions of the gcc libraries that were used by gcc6, where that 
differs from gcc7 (which is only libgfortran). libgcc45 provides the versions 
of the gcc libraries that were used by gcc45, where that differs from gcc6 
(which is libobjc-gnu).

No, since we were not involved in the creation of the openmodelica portfiles 
nor do we host them in our repository, and we have no influence over those who 
do host them to make any modifications. Send your problem report to the people 
who host the portfiles, i.e. the openmodelica people.
