Suggestion to change in the installation

[duguyue100]

Hi, I just compiled the ESIM on my Ubuntu 16.04 machine with ROS Kinetic. I just recently setup my machine so the OS is rather clean. I noticed two problems during the installation:

First, In this line: https://github.com/uzh-rpg/ze_oss/blob/master/ze_cmake/cmake/modules/ze_setup.cmake#L4

The option Werror is turned on so that some warnings in the pyconfig.h will be flagged as errors. With this, I couldn't compile ze_matplotlib

Second, while I was compiling ze_splines, it gives me the following errors:

/usr/lib/x86_64-linux-gnu/libapr-1.so.0: undefined reference to `uuid_generate@UUID_1.0'
collect2: error: ld returned 1 exit status
make[2]: *** [/home/dgywork/catkin_ws/devel/lib/ze_splines/viz_splines_test] Error 1
make[1]: *** [CMakeFiles/viz_splines_test.dir/all] Error 2
make: *** [all] Error 2

Turns out the version of libuuid supported by the Ubuntu 16.04 is too old. Since I have a conda on my machine, so I installed libuuid through conda to fix it:

conda install -c conda-forge libuuid

Hello,
Thanks for your feedback. I will leave the issue open for now in case anyone else runs into the same problem. I have never seen this problem, although I tested ESIM on the same system (Ubuntu 16.04 + ROS Kinetic). For reference, could you please tell me what version of Python, CMake, and gcc you are using?
Thanks.

Python version: 2.7.15
CMake: 3.5.1
GCC: 5.4.0

It's also the Ubuntu 16.04 + ROS Kinetic.

@duguyue100
conda install -c conda-forge libuuid didn't work for me.

Hi, @charleschen6 are you using the Python supplied by Ubuntu, Virtual environment, or Conda?
In my case, because I link ROS with Conda's Python, so I can use libuuid in Conda.
Otherwise, maybe build the newer library from scratch?

Regards,
Yuhuang.

Possible solution for libuuid:

"It is good to remove the libuuid library file under anaconda2/lib, and finally solved this problem."
ls ~/anaconda2/lib/libuuid*
mkdir ~/anaconda2/libuuid
mv ~/anaconda2/lib/libuuid* ~/anaconda2/libuuid
From here
