Arch Linux

In addition to the previous comment: You can also use the commit as patch directly (just add '.patch' to it's url).
Example, untested:

source=(...
jsonpp-include.patch::https://github.com/Sude-/lgogdownloader/commit/f039db5c6572c4fb70d228d511c4d76c1deb517c.patch)

prepare() {
cd $srcdir/$pkgname-$pkgver
patch -Np1 ../jsonpp-include.patch
}

This PKGBUILD works, it basically applies this commit:
https://github.com/Sude-/lgogdownloader/commit/f039db5c6572c4fb70d228d511c4d76c1deb517c

I have the same compiling problem as InspMustache. Any fix in sight?

Doesn't compile for me anymore since the latest update. Apparently json.h is missing.

Thanks for updating, but your package still invokes a manual "install" line and still does not use PREFIX and DESTDIR properly. Please fix :(

The "make install" line doesn't install the files to proper locations. You need to set DESTDIR and PREFIX appropriately, and also you should use quotations around environment variables to protect building under certain path names. Fixed PKGBUILD example: http://pastebin.com/TKGGcftU

Lots of new features in 2.18, better management of download locations etc. Full changelog as usual at the forum thread: http://www.gog.com/forum/general/lgogdownloader_gogdownloader_for_linux/post476

You can use 'make install' for the release build starting from the next version, it supports setting DESTDIR now.

@MindLikeWater You must remove the 'no-cover' option from ~/.config/lgogdownloader/config.cfg

I currently cannot build the package:

help2man -N -i man/lgogdownloader.supplemental.groff -o man/lgogdownloader.1 bin/Release/lgogdownloader
help2man: can't get `--help' info from bin/Release/lgogdownloader
Try `--no-discard-stderr' if option outputs to stderr
Makefile:99: recipe for target 'after_release' failed
make: *** [after_release] Error 1

Please also include the man page in the package.

Updated to 2.3, also a PKGBUILD for the -git version is at https://aur.archlinux.org/packages/lgogdownloader-git/

And it's fixed again.

Unfortunately the downloader is not working at the moment due to changes in the GOG API. The developer is working on fixing this. Follow developments here: http://www.gog.com/forum/general/lgogdownloader_gogdownloader_for_linux/post100

And we're already up to 1.15.

Sorry that took me far too long - it's been one of those weeks! The PKGBUILD is now updated and works with jsoncpp like it should.

Updated PKGBUILD for version 1.14 which works with jsoncpp version 0.5.0

I think you should not update to a version that requires unreleased versions of libraries. No one benefits from a PKGBUILD that does not build.
Better keep it at a version that builds, and upgrade only once all requirements can be met.

Updated to 1.12. Note that it won't build without modifying the jsoncpp package to install jsoncpp version 0.6.0-rc2.

Here's a PKGBUILD to do just that (you probably shouldn't use this):
pkgname=jsoncpp
pkgver=0.6.0
pkgrel=2
pkgdesc="A JSON C++ library"
url="http://jsoncpp.sourceforge.net/"
license="Public"
arch=('i686' 'x86_64')
makedepends=('scons' 'gcc')
depends=('gcc-libs')
source=("http://sourceforge.net/projects/jsoncpp/files/jsoncpp/0.6.0-rc2/jsoncpp-src-${pkgver}-rc2.tar.gz/download")
md5sums=('363e2f4cbd3aeb63bf4e571f377400fb')

build(){
cd ${startdir}/src/${pkgname}-src-${pkgver}-rc2
scons platform=linux-gcc

mkdir -p ${pkgdir}/usr/include/jsoncpp
cp -r include/json ${pkgdir}/usr/include/jsoncpp/json

mkdir -p ${pkgdir}/usr/lib
cp buildscons/linux-gcc-*/src/lib_json/libjson_linux-gcc*libmt.so ${pkgdir}/usr/lib/
cd ${pkgdir}/usr/lib/
ln -sf libjson_linux-gcc-*_libmt.so libjsoncpp.so

}

Woah! So sorry I forgot about this. I will have the updated PKGBUILD up shortly!

Here is an updated PKGBUILD for the version 1.11:
