Dear all, in a package I am maintaining (https://github.com/lbusett/MODIStsp), I use the `gdalUtils` package as a wrapper to call gdal processing utilities. The problem is that I can not find a way to run my test suite and examples on TRAVIS-CI. This appears to be 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 (in case 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 - sudo add-apt-repository -y ppa:opencpu/jq --yes - sudo apt-get -qq update - sudo apt-get install -y libgdal-dev libproj-dev - PATH="/usr/local/gdal/bin:$PATH" - export DISPLAY=:99.0 - sh -e /etc/init.d/xvfb start matrix: include: - os: linux dist: trusty sudo: required env: global: - R_LIBS="http://cran.rstudio.com"; - R_BUILD_ARGS="--no-build-vignettes --no-manual" - R_CHECK_ARGS="--no-build-vignettes --no-manual --as-cran" - R_CHECK_TIMINGS_="0" - BOOTSTRAP_LATEX="1" apt_packages: - libgdal-dev - libproj-dev - libcairo2-dev - libatk1.0-dev - libpango1.0-dev - libgtk2.0-dev - libglib2.0-dev - libcurl4-openssl-dev r_binary_packages: - cairoDevice - RGtk2 Do you have any suggestions to solve the issue? Do I need to somehow set the PATH to gdal in the travis.yml script? If so, how could I find out where gdal is being installed? ( I already tried adding a line like - PATH="/usr/local/gdal/bin:$PATH" in before_install within the yml but it did not work). Thanks in advance for any help!
