[basex-talk] proc:system

Hi, When I try to run proc:system("/usr/local/bin/tesseract") I get the error [proc:code0001] 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
