Does this patch help?

Apply to current git. It adds retry support to Downloader::getResponse which might help.

I'm having some issues. With:

'sudo apt-get install build-essential libcurl4-openssl-dev liboauth-dev libjsoncpp-dev libhtmlcxx-dev libboost-system-dev libboost-filesystem-dev libboost-regex-dev libboost-program-options-dev libboost-date-time-dev libtinyxml-dev librhash-dev help2man'

I get:

'Depends: libcurl4-nss-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages.'

I'm running ElementaryOS Luna x64 (if it matters).

The rest of it works (getting the file and all that) up until 'make release' where it says:

'/bin/sh: 1: g++: not found
make: *** [obj/Release/main.o] Error 127'

Any help would be appreciated, thanks.

Seems like there's some funky things in the ElementaryOS-Repo going on.

Since ElementaryOS is a "child" of Ubuntu (which is a child of Debian), you may want to try one of my DEB-binary-packages:

I've updated these packages to include the correct dependencies, so your package-manager should install missing libraries automagically.

Hope this works for you.

Still can't figure it out. Thanks for the help though. :D

Using: sudo dpkg --install lgogdownloader_2.12-1_amd64.deb

And just get a return of a bunch of packages that are not installed:

So no clue what it is I'm doing wrong. I should probably just download all my GOG stuff to a flash drive from another system or at work then copy 'em over.

Try using as root (or using sudo) on the command-line:

apt-get -f install

This should work it out and install all missing dependencies. :-)

After using sudo dpkg --install lgogdownloader_2.12-1_amd64.deb,
I use: sudo apt-get -f install

Well I assume that's what I'm trying to get to work, so I select No. So just try to use the login command (lgogdownloader --login and get:

lgogdownloader: error while loading shared libraries: libjsoncpp.so.0: cannot open shared object file: No such file or directory

Well, this is weird.

Try installing the dependencies manually using:

sudo apt-get install libboost-date-time1.49.0 libboost-filesystem1.49.0 libboost-program-options1.49.0 libboost-regex1.49.0 libboost-system1.49.0 libc6 libcurl3 libgcc1 libhtmlcxx3 libjsoncpp0 liboauth0 librhash0 libstdc++6 libtinyxml2.6.2


(all in one line)

and see what you get then. Hopefully the ElementaryOS-Repository has all the needed dependencies.

Welp. I give up. I'll just download from another system then copy 'em over. Way less hassle. Thank you very much for the time and patience. It's very much appreciated. :D

I had seen the same, and also 40x errors. Sometimes for single games, but often when I use --list-details.

I've tried the patch. It is a bit better because it doesn't stop with HTTP ERROR 500 in the first 10 entries, like in my last couple of tries, but it's a bit worse too, because it stopped at an HTTP ERROR 403 around game 70 and didn't show any signs of an error, except the HTTP ERROR at the top -- it then proceeded to list the games it had found, basically giving me an incomplete list.

The downloader does make a lot of requests in a very short time. Perhaps the server has some kind of DOS protection that causes problems for the downloader because of the many requests in a short time.
It might be a good idea to wait some time between the requests.

Try this patch
https://sites.google.com/site/gogdownloader/getresponse_usleep.diff

It adds 50ms wait to Downloader::getResponse and API::getResponse

That's probably a good idea, but it's not enough. :(
Getting game info 64 / xxx

and then it stopped again

Prebuilt package can depend on certain version of boost, which can be outdated. It's better simply to build it from source each time. Alternatively, may be someone can add it to Debian repository? It will need maintainers though, since package will have to be rebuilt periodically to sync with dependencies and updated releases.

For example on Debian testing, there is no boost 1.49. Current version is 1.54. I'm using lgogdownloader just fine there, after building it from source.

Also, if you have a ready deb file, sometimes dependeices specified in it aren't really correct (let's say newer version of boost is backwards compatible, though it's not always the case). You can simply extract the binary from deb without installing it:

dpkg -x some.deb some_directory/

This will unpack all contents to that directory.

Something's weird with moebius.

but whenever I try to download it, I get a 404 for the mac file.
Downloading it directly from the website works.

Does anyone else see this?

Well, this is the most problem, when the dependencies are not included in the release, makes things just more complicated than they should be =(
