[ROS] erle simulation enviroment setting error

When i followed the instruction of erle robot simulation.
I met glog_catkin error. the error started with

" Project 'rotors_control' tried to find library 'glog_catkin'. "
 
So i looked for the solution of this problem.
and i found this.

"http://forum.erlerobotics.com/t/rotors-control-cannot-find-library-glog/4410"

It says we should install glog package individually.

So i've cloned folder and installed it with following code.
(Ref. http://forum.erlerobotics.com/t/catkin-make-j-4-failed/4605/7)
$ cd ~/simulation/ros_catkin_ws/src
$ git clone https://github.com/google/glog.git
$ cd glog
$ sudo apt-get install autoconf

$ sudo apt-get install libtool
$ sudo ./autogen.sh && sudo ./configure && sudo make && sudo make install

Be sure you should input "sudo" in every command.

I've seen another error when i didn't put "sudo" in the command. 

but there is another error after those commands.

 

It says there is  error with "GFLAGS_NAMESPACE".

So I tried to find a solution again and i got this reference.

"http://blog.dreamlikes.cn/archives/957"

It says we should install gflag to build glog so i followed what it says.

# remove gflags
$ sudo yum remove -y gflags-devel
# install gflags
cd ~
$ wget -O gflags-2.2.1.tar.gz https://github.com/gflags/gflags/archive/v2.2.1.tar.gz
$ tar zxvf gflags-2.2.1.tar.gz
$ cd gflags-2.2.1

$ mkdir -p build && cd build

$ cmake .. -DCMAKE_INSTALL_PREFIX=`pwd`/../../gflags
$ make
$ make install

# original code was "$ cd ~/glog-0.3.5" but in this case we should wrote like below.

$ cd ~/simulation/ros_catkin_ws/src/glog
$ ./configure --prefix=`pwd`/../glog --includedir=~/gflags/include
$ make
$ make install

but there was another error.

I assumed it's the syntax problem. so i changed the includedir
"~/gflags/include" -> "/home/gflags/include"

 

but there were same errors like before,  so i looked for the source file and searched what is the purpose of "using namespace GFLAGS_NAMESPACE".

but there were no use of that macro. so i decide to delete it from all sources which have this line "using namespace GFLAGS_NAMESPACE".

in my case, five files have this line. those were logging_unittest.cc, demangle_unittest.cc, symbolize_unittest.cc, utilities_unittest.cc, sinalhandler_unittest.cc. after delete it i could success to build it.

 

but there was permission error. so i've put "sudo" in front of the command.

$ sudo make install

Finally, i could succeed to build it

the solutions above couldn't solve my problem after all.

"failed make[2]: *** [glog_catkin/glog_src-prefix/src/glog_src-stamp/glog_src-patch] Error 2"

i met this problem again and again so i refer to this page. 

"http://forum.erlerobotics.com/t/unable-to-compile-workspace-after-gazebo-install/4192"

and fixed the problem by copying "fix-unused-typedef-warning.patch" from /home/erle/simulation/ros_catkin_ws/src/glog_catkin to /home/erle/simulation/ros_catkin_ws/src 

and fixed /home/simulation/ros_catkin_ws/src/glog_catkin/CMakeLists.txt like this.

cs

after change all. you must reboot the PC. 
there are no change if you don't reboot.

and it works fine now!
