Problems with install.sh file

[merium]

Hi

I was able to solve the problem above by changing CmakeLists.txt

FIND_LIBRARY(LLT_LIBRARY  llt)
FIND_LIBRARY(MESCAN_LIBRARY  mescan)

to

FIND_LIBRARY(LLT_LIBRARY  libllt.so.1)
FIND_LIBRARY(MESCAN_LIBRARY  libmescan.so.1)

as mentioned in one of the comments. Now I get the following error:

/usr/local/lib/libllt.so.1.0: undefined reference to arv_buffer_get_status' /usr/local/lib/libllt.so.1.0: undefined reference to arv_buffer_get_data'
/usr/local/lib/libllt.so.1.0: undefined reference to arv_make_thread_high_priority' /usr/local/lib/libllt.so.1.0: undefined reference to arv_make_thread_realtime'
collect2: error: ld returned 1 exit status

Can you paste the full path you used with the install.sh script?
The error you get seems to be a problem with your aravis installation. Did you install it like in the install.sh script?

[merium]

The full path that I'm using with install.sh is
'/home/keppel/scanCONTROL-SDK/C++ SDK (Linux)/binaries(x86_64)/'

This is where my scancontrol SDK folder is.

[hartmanndennis]

The install.sh file expects '/home/keppel/scanCONTROL-SDK/C++ SDK (Linux)/' as input. I should have written it more clearly in the readme. Can you try it again this way?

[merium]

Now it says
Could not find /libmescan/ folder in /home/keppel/scanCONTROL-SDK/C++%20SDK%20(Linux)/binaries(x86_64)/.
You have to run ./install.sh "/path/to/C++ SDK (Linux)/" (binaries(x86_64) is located there)

Actually I have also tried manually adding all the paths in the install.sh file. After that I can run the install.sh file without any problems. However I can not use the launch file because their is no bin file created for the microepsilon_scan_control. To create a bin file I try to compile the repository you provide and that's when I get this error:

/usr/local/lib/libllt.so.1.0: undefined reference to arv_buffer_get_status' /usr/local/lib/libllt.so.1.0: undefined reference toarv_buffer_get_data'
/usr/local/lib/libllt.so.1.0: undefined reference to arv_make_thread_high_priority' /usr/local/lib/libllt.so.1.0: undefined reference toarv_make_thread_realtime'
collect2: error: ld returned 1 exit status

[hartmanndennis]

What does your C++ SDK (Linux) directory look like? For me it's

~/scanCONTROL-SDK/C++ SDK (Linux)$ ll

and binaries(x86_64):

Yeah I think I have the same files in the directory:

[hartmanndennis]

I just checked the install script again and got the same errors as you. I think I fixed the script now. Please pull the changes and try again.

[merium]

Unfortunately I still get the same error:

Could not find /libmescan/ folder in /home/keppel/scanCONTROL-SDK/C++%20SDK%20(Linux)/binaries(x86_64)/.
You have to run ./install.sh "/path/to/C++ SDK (Linux)/" (binaries(x86_64) is located there)

[hartmanndennis]

Are you inputting %20 instead of white space or is this just a visual bug? You have to use real white spaces. If it still doesn't work, try renaming the directory to a name without white spaces.

[merium]

Hey

Yeah I've already changed the name and the install.sh script can work.
However, I can still not use the scanner.launch file, it gives the following error:

ERROR: cannot launch node of type [microepsilon_scancontrol/microepsilon_scancontrol_node]: can't locate node [microepsilon_scancontrol_node] in package [microepsilon_scancontrol]

[hartmanndennis]

How did you compile the package?

[merium]

I've been trying to compile the package through catkin_make which is where I get the error in my second post:

/usr/local/lib/libllt.so.1.0: undefined reference to arv_buffer_get_status' /usr/local/lib/libllt.so.1.0: undefined reference toarv_buffer_get_data'
/usr/local/lib/libllt.so.1.0: undefined reference to arv_make_thread_high_priority' /usr/local/lib/libllt.so.1.0: undefined reference toarv_make_thread_realtime'
collect2: error: ld returned 1 exit status

[hartmanndennis]

arv_buffer_get_status is a function of aravis, so the aravis library didn't get installed correctly.

[merium]

Hey so I removed everything and installed from scratch, the bugs are removed and I can successfully compile the repository. However when I run the scanner.launch file, it says

I've checked my connections to the laser sensor and the laser is ON but the driver isn't being able to connect.

[hartmanndennis]

Can you connect to the sensor with the vendor software?

[merium]

Yes we can

[hartmanndennis]

This error means that the driver can't find any sensor in its subnet. If the sensor and the PC with the ROS node are in the same subnet and it can't find the sensor, I don't know what could be wrong.

[merium]

The issue is resolved. Thank you!
