Prequisites?

[rbarkas]

I did npm install aisdecoder

When I try to run your sample code I get:
var decoder = new AisDecoder;
^
ReferenceError: AisDecoder is not defined

Any suggestions?

[kintel]

Did you require the module correctly, i.e.var AisDecoder = require ('aisdecoder').AisDecoder; ?

[rbarkas]

Been away and just got back to it.

When I run npm install aisdecoder it complains 👍
../src/driver_ais.c:1052:4: warning: implicit declaration of function ‘strlcpy’ -Wimplicit-function- declarationstrlcpy(ais->type24.shipname,
^

here''s the output:

I'm running on an Ubuntu server, so I installed ;ibbsd-dev to try to get strlcpy. I get the same output from the npm install after installing libbsd-dev.

And when I run it I get the error:

node: symbol lookup error: /home/sop/switch/node_modules/aisdecoder/build/Release/aisdecoder.node: undefined symbol: strlcpy

[kintel]

Perhaps try to remove HAVE_STRLCPY in https://github.com/kintel/aisdecoder/blob/master/binding.gyp ?

[rbarkas]

Thanks Marius.

When I npm install aisdecode I get a version that has a much shorter
binding.gyp.

If I manually add the missing bits to binding.gyp and then npm rebuild
aisdecoder I get

aisdecoder@0.0.1 install /home/sop/node_modules/aisdecoder
node-gyp rebuild

I finally got aisdecoder to build and install by cloning the repo rather than using npm install aisdecoder.

Seems to work fine although the src from the gpsd project is a couple of releases behind.
I tried copying the new files from gpsd but that didn't work. I don't understand how the build process works so I can't help in troubleshooting the build.

Any chance that you could update to the latest gpsd code?

[kintel]

Looks like I had forgotten that I have to manually publish new versions.. The 0.0.2 version should be in npm now.
I'm not using this software myself any longer, so I'm not planning to sync against gpsd, but I'm happy to pass it on to someone else or accept a pull request.

[crueda]

i have the following error when i execute npm install aisdecoder:

pm WARN package.json log@1.4.0 No repository field.

any idea? :(

Thanks
