Segmentation Fault when launching roseus in 16.04

[Affonso-Gui]

When using the latest versions for jskeus (euslisp/jskeus@fa7b88f) and eus (d7a3284) from source in Ubuntu 16.04, running roseus leads to:

roseus ;; Segmentation Fault.
;; in (load-library "roseus.so" '("roseus"))
;; You are still in a signal handler.
;;Try reset or throw to upper level as soon as possible.
;; code=1757534960 x=68c1d9c0 addr=5

This problem does not occur in Ubuntu 14.04 nor when using eus version 1f5a9e9.

Verified the above in a total of 5 PCs (three of them 16.04, two of them 14.04).

roseus may be compiled with (euslisp/jskeus@fa7b88f)
(I do not test yet)

using roseus from apt seemed to be the reason for this. (conflicting definitions in eus.h)

Still testing, but seems that compiling roseus from source too does the job.

Was able to build and launch with the PR above. The remaining question is why does it work on 14.04 and not in 16.04? roseus version seems to be the same for both systems.

rosversion roseus
1.6.3

Also, in roseus.cpp it appears that we already had an optional documentation parameter using _defun (https://github.com/jsk-ros-pkg/jsk_roseus/blob/master/roseus/roseus.cpp#L1878-L1883)

Using _defun seemed more clear to me than using the #undef - #define schematics. Is this open to discussion?

@Affonso-Gui I think it also fails on indigo

Resuming:

• Segmentation fault is due to different eus.h versions between euslisp and roseus.
• Is solved by compiling roseus from source.

Just for the record:
instructions to compile both roseus & euslisp from source can be found in https://github.com/jsk-ros-pkg/jsk_roseus#use-roseus-with-euslisp-built-from-source
