in a package I am maintaining (https://github.com/lbusett/MODIStsp), I use the gdalUtils package as a wrapper to gdal utilities. The problem is that I can not find a way to run my test suite and examples on TRAVIS-CI. This appears to e related to the fact that the gdal installation folder is not found on the path, so that I receive the following error:
Warning in gdalUtils::gdal_setInstallation(ignore.full_scan = TRUE)
No GDAL installation found. Please install 'gdal' before continuing:
- www.gdal.org (no HDF4 support!)
- www.trac.osgeo.org/osgeo4w/ (with HDF4 support RECOMMENDED)
- www.fwtools.maptools.org (with HDF4 support)
(see here for the full build log: https://travis-ci.org/lbusett/MODIStsp/jobs/318037312)
gdalUtils::gdal_setInstallation() is supposed to search for a valid gdal installation, by first using sys.which(), and (incase it fails) looking on "typical" installation paths (see https://www.rdocumentation.org/packages/gdalUtils/versions/2.0.1.7/topics/gdal_setInstallation).
This happens besides gdal (apparently) being installed on travis in the build, using the following travis.yml configuration:
{
"language": "r",
"cache": "packages",
"warnings_are_errors": false,
"before_install": [
"sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable --yes",

Do you have any suggestions to solve the issue? Do I need to somehow set the PATH to gdal in the travis.yml script? If so, how could I find out where gdal is being installed? (I tried adding a line like "PATH=\"/usr/local/gdal/bin:$PATH\"" in the yml but it did not work.
Thanks in advance for any help!
In the end the issue was solved by simply adding installation of gdal-bin in the yaml trough:
sudo apt-get install -y gdal-bin
