asymptote @2.96 fails to build: ModuleNotFoundError: No module named 'PyQt5'

[barracuda156]

This bug was fixed once, I think, and now it is back:

It also misses a required dependency:

:info:build checking for atomic_ops.h... no
:info:build configure: error: libatomic_ops is required.  You can either install it on
:info:build                   your system, or fetch and unpack a recent version into the
:info:build                   source directory and link or rename it to libatomic_ops.

[barracuda156]

Oh great, adding libatomic_ops still does not fix it, apparently:

config.status: error: in `/opt/local/var/macports/build/_opt_local_ppcports_graphics_asymptote/asymptote/work/asymptote-2.96/gc':
config.status: error: Something went wrong bootstrapping makefile fragments
    for automatic dependency tracking.  If GNU make was not used, consider
    re-running the configure script with MAKE="gmake" (or whatever is
    necessary).  You can also try re-running configure with the
    '--disable-dependency-tracking' option to at least be able to build
    the package (albeit without support for automatic dependency tracking).
See `config.log' for more details

Looks like upstream has broken building with external GC, so the build tries to set GCLIB='$(GC)/.libs/libgc.a'.

[Schamschula (Marius Schamschula)]

It sounds to me like we a missing something else that got opportunistically linked or was already installed on my system.

Oh, do I want trace mode back!

[Schamschula (Marius Schamschula)]

I just noticed that port:py${python.version}-pyqt5 has been commented out. I do have that installed.

This error is being ignored.

[Schamschula (Marius Schamschula)]

However, my build does generate the missing file:

marius@Mira ports % ls -al graphics/asymptote/work/asymptote-2.96/gc/.libs/libgc.a
-rw-r--r--@ 1 macports  wheel  805312 Feb  8 15:53 graphics/asymptote/work/asymptote-2.96/gc/.libs/libgc.a

We should be using the MacPorts version @

/opt/local/lib/libgc.a

[barracuda156]

Replying to Schamschula:

I just noticed that port:py${python.version}-pyqt5 has been commented out. I do have that installed.

This error is being ignored.

Yes, that is not the error which breaks the build indeed (and pyqt5 one should be ignored, though I would prefer a more sensible way to deal with it, but this is what upstream settled on).

Re GC, take a look at upstream comments. They removed support for external GC on purpose and want it to be that way. (Of course, this does not mean that MacPorts must follow that).

[Schamschula (Marius Schamschula)]

I'm not sure why this error occurs on the build bots. I have cleanly built version 2.96, 2.97 and 2.98 on my Sonoma machine.

[johncbowman (John Bowman)]

The difference probably has to do whether you have autoconf installed. For the solution, see ​https://github.com/macports/macports-ports/pull/27612#issuecomment-2646632364

[johncbowman (John Bowman)]

See ​https://github.com/vectorgraphics/asymptote/issues/521#issuecomment-2644549764 for the rationale for using an integrated garbage collector in Asymptote. Boehm gc is a small library; it only adds 145kB to the stripped binary. Also, in the version we compile we exploit the fact that our application is single threaded; the second thread is only used for OpenGL rendering (long ago MacOS forced this requirement on us:-).

There is something wrong with the syntax here (so just adding --disable-dependency-tracking is not enough):
