No. You need to have inkscape installed (and in your PATH) for svg to
pdf conversion to work.
FWIW, I cannot find the intermediate file

@Hans, could we change the conversion so that it checks for inkscape and

How about just implementing the unix which command in lua?
(untested code)
function which(string file)
local path = os.getenv("PATH")
local splitter = lpeg.splitat(io.fileseparator)
local directories = lpeg.match(splitter, path)
for dir in directories
if io.exists(file.join(dir,file)) then
return true

There is also rsvg-convert (from LibRSVG[1]) which can be faster (but in some corner cases, as accurate as Inkscape).

I don't know about robustness, but “which inkscape” seems to be the candidate from my point of view for POSIX systems. The windows equivalent would be “WHERE inkscape” according to google (untested).

[NTG-context] Simple rings with svg
I read on the wiki that now svg is natively supported. Hmm. I am missing a trick here: I try ___ \starttext Hello world \externalfigure[ChangingField_ILUC.pdf \stoptext __ And all goes as expected: I get output with the expected graphic in place But if I try ___ \starttext Hello world \externalfigure[ChangingField_ILUC.svg] \stoptext ___ I get : !LuaTeX error: cannot find image file 'm_k_i_v_ChangingField_ILUC.pdf' ==> Fatal error occurred, no output PDF file produced! Is it time to update context? From the date of the wiki revision it seems not, since I am on ConTeXt ver: 2011.11.29 23:11 MKIV FWIW, I cannot find the intermediate file 'm_k_i_v_ChangingField_ILUC.pdf' on my disk either…both graphics files are in the same location, both exist, both are named correctly….
