rosmake lsd_slam error

[SherlockMoriaty]

I compile the lsd_slam by typing: rosmake lsd_slam. But I get some failures, which shows that "[ rosmake Built 41 packages with 1 failures]". Can you kindly help me solve the problem? Below are the whole messages.

I also experienced the same problem.

Exception: quotes not allowed in description string log10 of threshold on point's variance, in the respective keyframe's scale.

I solved the problem by replacing "'" in description string in cfg files with "`".

like this: Edit lsd_slam/lsd_slam_viewer/cfg/LSDSLAMViewerParams.cfg I rewrote line 20 from "log10 of threshold on point's variance, in the respective keyframe's scale. " to "log10 of threshold on points variance, in the respective keyframes scale. " Make the same changes for lines 21 and 30.

Edit lsd_slam/lsd_slam_core/cfg/LSDDebugParams.cfg Make the same changes for lines 11, 12 and 48.

There's a fix for this in pull request #263

@Young532042725 @SherlockMoriaty You can get around this problem by removing all the single quotation marks currently present in some of the strings in LSDSLAMViewerParams.cfg and any other .cfg file.

As an example, what I did to fix this was change this: gen.add("scaledDepthVarTH", double_t, 0, "log10 of threshold on point's variance, in the respective keyframe's scale. ", -3, -10, 1) to this: gen.add("scaledDepthVarTH", double_t, 0, "log10 of threshold on the variance of a point, in the respective scale of the keyframe. ", -3, -10, 1)

This 'single quotation mark removal' was applied to all the strings in all files which caused errors at compile time. If you don't give a damn about grammar, just remove the single quotation marks from the strings and voila :grin:
