clang++: command not found

clang++: command not found

clang++ work outside of this program. But when I run this program show this error message clang++ command not found


PATH=/home/musleh/programming/cpp
DIR=''
FILE=''

execute () {
    cd ${PATH}/${DIR}
    clang++ ${FILE} -o a 
    time ./a
    rm a

    if [[ $? -ne 0 ]]
    then
        echo "***************************Program Fail***************************"
    fi
}

while getopts i:d: OPTION 
do
    case ${OPTION} in
        d)
            DIR=${OPTARG}
            ;;
        i)
            FILE=${OPTARG}
            ;;
        ?)
            usage 
            ;;
    esac
done

if [[ $# -lt 4 ]]
then
    usage
elif [[ ! -d ${PATH}/${DIR} ]]
then
    echo "${DIR} dir not found!" >&2
elif [[ ! -f ${PATH}/${DIR}/${FILE} ]]
then
    echo "${FILE} file not found!" >&2
else
    execute
fi```

PATH=/home/musleh/programming/cpp

Is very probably wrong and should be instead perhaps

PATH=/usr/bin:/bin:/usr/local/bin:$HOME/programming/cpp
export PATH

Read much more more about the PATH variable and execvp(3) (which most shells use)

Use strace(1) on your shell script. Read Advanced Linux Programming and more about syscalls(2).

Study for inspiration the source code of GNU bash and read its documentation. It is free software so your are allowed to study (and perhaps improve) its source code.

Of course, clang++ needs to be installed. Check by using the which command. Or view your PATH variable using echo $PATH
