After updating Inkscape for the 1.0 version the svg package invocation of inkscape leads to the following message in the log file:
Package svg Info: Calling Inkscape on input line 19. runsystem(inkscape -z -C --export-latex --file="truss.svg" --export-pdf="truss _svg-tex.pdf" )...executed.
Package svg Warning: The export with Inkscape failed for file (svg)
`truss.svg' (svg) Troubleshooting: Please check in the log file how (svg) the invocation of Inkscape took place and try to (svg) execute it yourself in the terminal on input line 19.
and the files "truss_svg-tex.pdf" and "truss_svg-tex.pdf_tex" are not created. I tried to execute the command
inkscape -z -C --export-latex --file="truss.svg" --export-pdf="truss_svg-tex.pdf"
in the command prompt and the two files "truss_svg-tex.pdf" and "truss_svg-tex.pdf_tex" were not created and a strange message was issued: "OpAA". Of course, a workaround is to open Inkscape and do File->Save As->pdf and then choose the "Omit text in PDF and create LaTeX file" option. Finally "_svg-tex" has be added to name of both files created. However, this is very unpleasant.
