svg output passes invalid option --libgs to dvisvgm about asymptote

[zoggy]

Thanks for the --libgs="" trick, that should do it.

Presumably you are in case 1 (see below). The bug here is really in dvisvgm; it should still accept libgs and either use it instead or simply ignore it. In any case you can override with asy --libgs=""
or putting in your config.asy configuration file (in the .asy subdirectory of your home directory):

import settings
libgs=""

1.dvisvgm -h doesn’t list option --libgs but dvisvgm -l lists entry ps
libgs was linked during build time.
PostScript support is always enabled.

You simply need to compile dvisgm with PostScript support.

Thanks. In fact, dvisvgm has PostScript support (ps appears in dvisvgm -l), but asy is not aware of this and passes --libgs to dvisvgm. There seems to be no way to tell asy not to pass this option.

[johncbowman]

You simply need to upgrade dvisvgm; Asymptote requires version 1.5.3 or later.

I'm using dvisvgm 2.0.4 that I compiled myself, and a packaged asymptote 2.37.

From http://dvisvgm.bplaced.net/FAQ

dvisvgm -h doesn’t list option --libgs and dvisvgm -l doesn’t list entry ps
dvisvgm was built without PostScript support. There’s no way to activate it. Try to get a binary with PS support enabled.

[zoggy]

As I stated before dvisvgm -l does list a ps entry, but it has no --libgs option. So PS support is enabled, but so enabled that it does not require, and does not support, --libgs option.
