Similarly:

proc:system("tesseract") returns [proc:error] Cannot run program "tesseract": error=2, No such file or directory

Similarly:

proc:system("tesseract", (), map {"dir" : "/usr/local/bin/"}) returns [proc:error] Cannot run program "tesseract" (in directory "/usr/local/bin"): error=2, No such file or directory

The command "tesseract" works at the command line. I suspect there may be a problem with permissions: is there a way to overcome this error? Thanks.

Best,

Giuseppe
