New port: asymptote

[loshea@…]

A language for producing high quality vector graphics.

[loshea@…]

This port depends on teTeX. However teTeX is dead and nost LaTeX users use MacTeX (or the related TeXLive). Perhaps the port should depnd on the new TeXLive port. Comments welcome.

The link phase generates some warnings, although the application seems to work fine. Here is the command and the errors I get on OSX 10.4.10 on Intel hw.

Some remarks

1. The other libraries asymptopte may use can be added to dependencies list unconditionally or as variants:

depends_lib port:fftw-3 port:gsl port:libsigsegv port:ncurses

2. May be it is better not to install into texmf-dist, but into texmf-local

configure.args --with-latex=${prefix}/share/texmf-local/tex/latex --mandir=${prefix}/share/man

3. In checksums section use name like ${distname}.src.tgz to minimize changes for the next version.

Thanks for packaging asymptote!

HMUG gives this list of dependencies for OSX 10.4 on ppc and x86:

http://www.hmug.org/pub/MacOS_X/X/Applications/Publishing/asymptote/

My annotations in parentheses -- several packages should probably be made optional; I set g95 optional (won't build on 10.5.1) and also X11 (do we need it? It pulls in a lot of dependencies). I'd be happy if asymptote can generate eps files.

Dependencies:
bzip2 1.0.4 (ok)
fftw 3.1.2 (fftw-3 ok)
fltk 1.1.7 (ok)
freetype 2.3.5 (ok)
g95 20061019 (optional -- macports has 0.90)
gawk 3.1.5 (ok)
gettext 0.17 (ok)
ghostscript 8.60 (8.61)
ghostscript-fonts-std 8.11 (ok, in ghostscript)
gsl 1.9 (1.10)
ImageMagick 6.3.6-2 (6.3.7-1)
jasper 1.900.1 (1.701.0 -- may be worth updating)
jbigkit 1.6 (ok)
jpeg 6b (ok)
lcms 1.16 (ok)
libexif 0.6.16 (0.6.15)
libiconv 1.12 (ok)
libpng 1.2.23 (ok)
libwmf 0.2.8.4 (ok)
libxml2 2.6.30 (ok)
mpeg2vidcodec 1.2 (ok)
openexr 1.4.0 (ok)
pkg-config 0.22 (pkgconfig ok)
Python 2.5.1 (python25 ok)
readline 5.2 (ok)
sed 4.1.5 (gsed ok)
tetex 3.0 (ok)
texinfo 4.11 (ok)
X11 1.1.3 (xorg-libX11 ok -- optional?)
zlib 1.2.3 (ok)

I'm not familiar with the dependency trees, so I don't know the shortest list that will pull in all of these.

When I run the modified portfile, leaving out xorg-libX11, odcctools builds on 10.4.11, but fails on 10.5.1 (both macintel) (Ticket #13289).

Moving g95 to optional (don't know when it's needed) allows some further progress on 10.5.1.

TeTeX fails to build on 10.5.1 -- Ticket #13491.

asymptote builds on 10.4.11 and creates valid eps files! Very cool.

The revised portfile is likely overkill:

master@… and Dave -- thanks for your comments.

How does one determine the full set of dependencies (without using HMUG)? I would like to verify that we have the right list. Does HMUG list the deps of asymptote, or its transitive closure? If the latter, then it would be nice to find what the direct deps of asymptote are (as Dave says).

[loshea@…]

It would be nice to tease Hans_Boehm/gc out into another port and then list that as another dep. However this might be best left to a later day, since I think some patching will be needed to get this to work.

What do people think?

For example, is ImageMagick really a dependency of asymptote? I think (but could be wrong here) that it is only needed if you want to use asymptote to produce (say) JPEGs. (*)

In some ways, ghostscript is similar (again, I'm speculating) in that it is needed only to produce PDF output. However, since asymptote wants to generate PDFs as part of its own documentation, that promotes it to proper dependency.

Any opinions on this, especially (*) ?

It is already ported. Try

port info boehmgc

Exactly. As of 1.37 asymptote fails to build with system gc. The bug was reported (by me) to the author and the report has been acted upon. But I have not tested the development version after the fix.

[loshea@…]

In view of http://lists.macosforge.org/pipermail/macports-users/2007-December/007354.html I propose making the following changes to the portfile (thanks Michail and Dave).

1. Install into texmf-local

2. Make use of ${distname}

3. Alter dependencies to at least:

depends_lib     port:fftw-3 port:gsl port:teTeX port:readline port:ghostscript

I still am unsure about some possible additional dependencies. Michail: how does asymptote use libsigsegv and ncurses? Dave: is it reasonable to not include ImageMagick as a dependency?

As soon as we agree on something reasonable, I'll try to get it committed (I am not a committer).

Thanks!

I really do not care. I can see (from configure.ac) that asymptote looks for ncurses and libsegsegv. It can work without libsigsegv, since it is just an optional library to handle page faults. It can be linked to system ncurses, but the current macports policy is to rely on its own libraries. It is linked to ncurses - use "otool -L" on the asy binary.

What I really dislike is port:teTeX, since teTeX is obsolete and TeXLive is already ported. A better way is to change it to something like bin:tex:teTeX (do not install teTeX if we already have tex) or make two variants, teTeX and TeXLive, with port:teTeX and port:texlive respectively.

[loshea@…]

I have uploaded a new Portfile.

I added these as dependencies.

I have added port:texlive as a dependency, since teTeX is dead. If there are no objections I'll request that it be committed.

In the meantime, I'll look into a variant that will allow xasy to work, but I will not delay things further while I look into that.

[loshea@…]

Bump version.
