@all

In case you wondered, you can fetch the `grass7' PKGBUILD that `gdal-grass' depends on from my GitHub (https://github.com/czka/AUR-grass7) or GitLab place (https://gitlab.com/tutturu/grass7_pkgbuild).

I'm not allowed to upload `grass7' to AUR, because it was rated not different enough from `grass'. Anyway, it's different enough to make a difference in practice ;).

@dreieck

This package was not meant to work with the AUR `grass` package as it is currently. Please see my pinned comment dated 2016-04-13.

Of course technically there's nothing preventing you from building it against AUR `grass` package, given you tweak the PKGBUILD as you described.

AUR grass package now defaults to version 7 and installs to /opt/grass, not /opt/grass7.

So, you need to adapt your PKGBUILD:

* Change in the depends-array "grass7" to "grass>=7",
* change in the build-function "--with-grass=/opt/grass7" to "--with-grass=/opt/grass".

(Error message is: configure: error: --with-grass=/opt/grass7 requested, but libraries not found!)


With that changes it works fine for me.

GDAL in Arch repository comes without GRASS support. There's no need to rebuild it before building gdal-grass. See this:

Before installing gdal-grass:

$ gdalinfo --formats | grep -i grass
GRASSASCIIGrid -raster- (rov): GRASS ASCII Grid
$ ogrinfo --formats | grep -i grass
(no output)

After installing gdal-grass:

$ gdalinfo --formats | grep -i grass
GRASS -raster- (ro): GRASS Rasters (5.7+)
GRASSASCIIGrid -raster- (rov): GRASS ASCII Grid
$ ogrinfo --formats | grep -i grass
OGR_GRASS -vector- (ro): GRASS Vectors (5.7+)

Or did you mean something else?

You are correct about the extra `/' in --prefix. I'll remove it in a next release. It doesn't do any harm though - GNU/Linux doesn't mind double leading slash `//' in a path. It treats it identical to a single leading slash `/'.

Nice work but to make it work, I think that you need to build gdal without grass support according to https://grasswiki.osgeo.org/wiki/Compile_and_install_GDAL-GRASS_plugin

On line 20 of your PKGBUILD you have:
--prefix=/${pkgdir}/usr

I am not sure but I think that it should be replaced by (without "/" at the beginning):
--prefix=${pkgdir}/usr

Thanks again
