If I will need to return '' and '\lib' to the Path. I will soon find out if I can rely on the built-for-Perl, Image::ExifTool derived [ exiftool on the command line and in R, or
Despite this, 'exifr' continues to load (it finds exiftool on the command line at 'exiftool').
After building 'Image::ExifTool', I have removed '' and the associated '\lib' directory from the Path,. After building 'Image::ExifTool', exiftool also invokes exiftool. "'exiftool' is not recognized as an internal or external command, operable program or batch file." 
Before building 'Image::ExifTool', invoked exiftool, but exiftool yielded the error message. With a second perl-script I write these changed values back to the file. Steps taken by each of the commands spill across the screen. I am using ExifToolVersion : 9.13 to read out metainformations of a pdf-file to formfields, where users can edit the values. Using gmake in the above sequence works. Strawberry Perl 5.30.0.1 warns that 'dmake' is no longer part of Strawberry Perl and suggests gmake. Perl forums suggested dmake or nmake when make was not available or didn't work on Windows. The frequently recommended sequence of commands at the Command Prompt:Īppeared to do something, but the command exiftool -ver failed and cpan -l (list of installed modules) did not include any 'Image::ExifTool::' entries. To make 'exiftool' available in Perl, build the 'Image::ExifTool' module. If not, check getOption("exifr.exiftoolcommand") and getOption("exifr.perlpath") again. library(exifr) should successfully load 'exifr'. getOption("exifr.exiftoolcommand") should report the value set in '.Rprofile'. R will check the '.Rprofile' file as it launches. Close and restart RStudio by opening the Project file (.Rproj) in the Project. Options(exifr.exiftoolcommand="C:\\Windows\\") points 'exifr' to 'C:\Windows'. If 'exifr' fails to load, tell it where '' is located using an '.Rprofile' file saved to the RStudio Project folders for which 'exifr' is required. Install R package 'exifr' with install.packages("exifr"). The version number should display on the next line. Confirm that '' is available on the Path by opening a Command Prompt, typing -ver and hitting Enter. Or, create a new directory (no spaces in path to be careful) and add the directory to the System Path environment variable. Rename 'exiftool' to '' and copy along with the '\lib' directory to 'C:\Windows'. Command line options (gnu tar?) exist and WinZip works. Currently the file is "Image-ExifTool-11.54.tar.gz". Download the platform-independent Perl library from ExifTool homepage.Confirm Perl installation by opening a Command Prompt and typing the command perl -version.I accepted the default 'C:\Strawberry' option. Download Strawberry Perl and install to a directory without any spaces in filepath.
How to Configure System for R exifr Using Strawberry Perl on Windows 10
SOLUTION: Replace make with gmake in each of the above. make, make test, and make install appear to do something, but do not build Image::ExifTool. make might be in the Path for my configuration of Windows 10. Tried to build Image::ExifTool using make command. Save a copy of this '.Rprofile' file to each RStudio Project directory for which 'exifr' is required. EXAMPLE: options(exifr.exiftoolcommand="C:\\Windows\\"). SOLUTION: Set 'exifr.exiftoolcommand' option to the filepath of '' in an '.Rprofile' file. 'exifr' does check the 'exifr.exiftoolcommand' option, which is not normally set when 'exifr' loads. 'exifr' does not look for in 'C:\Windows'. 'exifr' does not look for in the Path. As of July 2019, exiftool is the only command that 'exifr' looks for in the Path. Couldn't get the R package 'exifr' to load after placing ' and '.\lib' in 'C:\Windows'. SOLUTION: moved '' and '.\lib' to 'C:\Windows'. Subdirectories of 'C:\Windows' are not in the Path. Copied '' and '.\lib' to 'C:\Windows\exiftool'. Increased Verbose level of "nothing changed" message added in 12.Initial setup of Perl and exiftool for use with the R 'exifr' package took many hours (reading forums) when setup should have taken minutes. Improved round-off errors when writing QuickTime:MatrixStructure via the Composite:Rotation tag. Decode a couple of new FujiFilm tag (thanks Honza Pokorny). Decode a new Nikon tag (thanks Warren Hatch). Decode STANAG-4609 MISB GPS information from M2TS videos. Decode a couple of new Panasonic tags, and improved decoding of others. Decode more tags for the Sony ILME-FX30 (thanks Jos Roost). Added a new SonyModelID and Sony LensType (thanks Jos Roost). Added support for new XMP-photoshop:CameraProfiles structure.
