guidogetpagemap ./test.gmn
# get page mapping for ./test.gmn
Segmentation fault (core dumped)

I meet this error, can not run guidogetpagemap or guidogetpagecount

Please, post the corresponding guido code.

Can't reproduce the problem. Could you send more information: guido engine version, your platform, etc.

[motniemtin]

I do command guidogetpagecount $guidofile but get Segmentation fault (core dumped)

version 1.7.4 centos 8

[dfober]

Sorry, I don't have any computer running centos. I guess you're using a fresh build of the project and that it has been properly installed. Can you get more information regarding the seg fault? Do you have a similar problem with the other tools ? (e.g. guido2svg)

Error happen in guidogetpagecount guidogetpagemap guidogetsystemcount guidogetsystemmap

I found that problem is SVGSystem sys; or CairoSystem sys; Error fix with SVGSystem

[dfober]

GUIDO Graphic device is still based on the old cairo system. It might be due to that. Did you fixed it ?

[motniemtin]

I has fixed for guidogetpagecount.cpp change CairoSystem to SVGSystem
