aduvenhage / ais-decoder Goto Github PK

A problem with the following messages from Transas simulator:

!AIVDO,2,1,7,,53`t?>@2Dvop4i0P400u>3<0000000000000001JD@>D:3?00Gh00000000,0*7C
$AITXT,1,1,22,AIS: external GNSS in use*41

Might be wrong but still get parsed fine by maritec.co.za

The second one complains on CRC.

I have problems installing the requirements.txt file inside docker. I get "
Installing collected packages: six, python-dateutil, pytz, pandas
Running setup.py install for pandas: started
Running setup.py install for pandas: finished with status 'error'

This can be fixed by having "RUN pip install pandas" and "RUN pip install numpy" in the dockerfile. This seems to be known pip issue.

The __builtin_bswap64 causes problems on Windows (Visual Studio 2022 with cpp 20)
_byteswap_uint64 seems like a solution to this, but I haven't tried yet - will do in a couple of days.

I run into issues when building the python docker container. It seems that the repo for jessie images has moved so doing some apt-get install tasks fail. This can be fixed by changing the base image to python3.6-stretch

I followed the installation instructions on Ubuntu 20.04:

git clone https://github.com/aduvenhage/ais-decoder.git
mkdir ais-decoder-build
cd ais-decoder-build
cmake ../ais-decoder -DCMAKE_BUILD_TYPE=RELEASE

The last command gave me an error:

$ cmake ../ais-decoder -DCMAKE_BUILD_TYPE=RELEASE
CMake Error: The source directory "/home/steen/radio/ais-decoder/ais-decoder" does not exist.
Specify --help for usage, or press the help button on the CMake GUI.

I typed cd .. and the cmake command worked. So I'm not sure what the -build directory is for.

Hi, I ran into an issue when building the Python module on Windows 10. I am using the Annaconda command prompt because I don't have Python on my Windows PATH.

I have Visual Studio, CMake and SWIG installed (SWIG was installed through Annaconda). I also used Chocolatey to get the 'make' command in setup.py to work on Windows.

I cloned the repository, changed to the 'python' directory and ran 'python setup.py build'. I got the error:

'ais_decoder_wrap.cpp(3132): fatal error C1083: Cannot open include file: 'ais_decoder/ais_quick.h': No such file or directory'.

The directory 'ais_decoder/' was created inside 'python' but it didn't contain ais_quick.h I got the same issue when I tried to building manually with CMake (into the python directory) and then runnning 'python setyp.py install'.

I tried the manual build but wasn't able to get the c++ command to work (I tried installing g++ instead but the installation failed).

This project would be perfect for my task, any help would be greatly appreciated. Thank you!

The readme says: "Do the following test:

#!/usr/bin/env python3
import ais_decoder

str = "!AIVDM,1,1,,A,13HOI:0P0000VOHLCnHQKwvL05Ip,0*23\n"
ais_decoder.pushAisSentence(str, len(str))

n = ais_decoder.numAisMessages()
msg = ais_decoder.popAisMessage().asdict()

Running this test gives me

Traceback (most recent call last):
  File "./ais-test.py", line 5, in <module>
    ais_decoder.pushAisSentence(str, len(str))
AttributeError: module 'ais_decoder' has no attribute 'pushAisSentence'

on Ubuntu 20.04.
