Segfault on OS X

[noqsi]

While lepton compiles on OS X (version 10.9.5), it does not function properly

When I first start gschem, it does not display any of the widgets (see the screen capture below). If I mouse over them, the widgets slowly reveal one by one. This is also true of the menu widgets. The scroll for the drawing area is also out of place.

After a short amount of use, I get a segmentation fault with the following logged errors:

2017-02-27 20:11:02.111 gschem[96694:507] *** WARNING: Method userSpaceScaleFactor in class NSView is deprecated on 10.7 and later. It should not be used in new applications. Use convertRectToBacking: instead.

@noqsi After some googling I found this. Two links there point to gtk3 code and to documentation for class NSScreen used in apple products (and in quartz among others). One of the gtk2 artifacts in the new gtk3 code is still the method userSpaceScaleFactor reported on your console. It is deprecated in OS X 10.7 and later, as the error says. As far as I can see on the first page, using link to differences between gtk 3.22 and 3.89, nothing has changed even in the latter version. We even don't support gtk3, so the situation with first warning seems to be hopeless :-( I don't know if the two errors after it are someway bound to it, though.

@noqsi couple of questions:

• did gEDA/gaf run on OS X for you?
• Is this under homebrew, macports or 'fink or similar? or is it a completely native XCode build?

I ask the former because I did some work on getting gEDA to build under macports but Apple were making it harder and harder with each OS X release and I eventually realised it was much easier to run it under Parallels in a Linux guest.

[noqsi]

gEDA/gaf 1.8 runs on OS X for me, although the graphics are glitchy.

This is under homebrew.

[gareth8118]

Ah, I'd been avoiding homebrew on my current MBP because it used to conflict badly with csound in its use of /usr/local but it looks like hb has moved into /usr/local/Homebrew now? If I get time, I may install hb to try to reproduce this but I can make no promises!

[graahnul-grom]

Do we intend to support Mac? If we don't, we should state that in README (and list supported systems/architectures there - Linux, BSD, Windows/Cygwin).
I have no access to any mac hardware, so I cannot help here.

FWIW, I found a similar bug on launchpad:
gschem rendering issues on Mac OSX

[vzh]

@noqsi, have you tried to build lepton on Mac since then?

[noqsi]

I have not tried it. To use Lepton on my Mac, I have an Ubuntu VM. I could try building and running 1.9.10 natively.

[vzh]

It would be much appreciated. Please try.

[noqsi]

configure gives me:

configure: error: Your awk (/usr/local/bin/gawk) is missing the gsub' and/or toupper' functions.

while homebrew upgrade gawk fails, complaining that my OS (10.12) is no longer supported. I suppose I could try upgrading the OS, but this is an old Mac, and it's too important in my present situation for me to feel comfortable experimenting with changes that drastic right now.

[vzh]

Just out of curiosity, your OS should have some other awk (nawk, mawk, ...)? Maybe it supports those functions.
Just found that on my system there are 2 awk binaries: gawk and mawk. On Debian (and its derivatives) the one working is chosen via the alternatives facility. Maybe your Mac supports something like this?

[noqsi]

Good idea. After I removed gawk, it was happy with the native awk. Then, with the use of --disable-update-xdg-database, I was able to get configure to succeed. make then got a lot done, but eventually failed with makeinfo: unrecognized option '--css-ref=lepton-scheme.css'

[noqsi]

OK, installing texinfo and doing export PATH="/usr/local/opt/texinfo/bin:$PATH" got it to build. Still problems. Here's lepton-schematic:

No menus. There appears to be no text in the schematic, but it's just very tiny. Mousing over the blank upper part gets menus and widgets to appear. Creating a new page works, but adding components to it soon generates an error:

So there are issues with text rendering, preview widget (eda_renderer_finalize), and menus. The two former issues may relate to our cairo rendering. The latter one is questionable...

[graahnul-grom]

geda-gaf 1.10 has been added to macports recently.
If it's there, chances are lepton could be built under macports, too.
macports system is similar to FreeBSD ports, so I think it's worth a try.
The problem is that I have no mac machine to do it.
I've found an article describing the process of installing MacOS 10.13 ("High Sierra") in VirtualBox, but you need a mac to download the installer (~8Gb) from the Mac App Store and create an ISO image.
I'll ask my friends if anybody has a mac, good internet connection and
enthusiasm to help us with that. :-)
