Generated absolute path via for in doesn't exist

This is seriously confusing me, this:

Code:

PRJ_DIR=$(pwd)/ SRC_DIR=${PRJ_DIR} OUT_DIR="${ALL}/lu" OBJ_DIR=${PRJ_DIR}objs chkdir "${OBJ_DIR}" OBJ_DIR="${OBJ_DIR}/${O_DIR}" ... echo Compiling Lu Objects chkdir "${OBJ_DIR}" chknam(){ n=$(basename $1) compile_obj "${OBJ_DIR}/$n.o" $1 true } for i in "${SRC_DIR}"*.c do chknam "$i" done unset chknam

Resulted in this:

Code:

sh build.sh (in directory: /media/zxuiji/ZXUIJI_1TB/github/lu/lu) CPATH=/media/zxuiji/ZXUIJI_1TB/common/lua-5.3.5/src LPATH=/media/zxuiji/ZXUIJI_1TB/common/lua-5.3.5 Compiling Lu Objects gcc -Wall -o "/media/zxuiji/ZXUIJI_1TB/github/lu/lu/objs/gcc/LuScript.c.o" -c "/media/zxuiji/ZXUIJI_1TB/github/lu/lu/LuScript.c" gcc: error: "/media/zxuiji/ZXUIJI_1TB/github/lu/lu/LuScript.c": No such file or directory gcc: fatal error: no input files compilation terminated. ...

Found the problem, apparently gcc & other compilers must be run with root permissions ( ͠° ͟ʖ ͡°)

Edit: Nope, only works when I type directly, this is sooo WTF!?
Here's a root permission terminal output trying both

Well there's certainly no reason for running the compiler as root, unless you have basically no permissions to write to directories.

A problem might be your mis-matched quotes on the .o file

Okay tried modifying my build script to put the full command in a string and it finally found the file, makes me think the shell puts it in a fake environment when executing via a variable's contents, here's the snippet I'm using after modified the script several times and reaching this point:

Code:

compile_c() { local c="${CC} ${CFLAGS}" echo "$1 from $3" chkdir "$2" for i in "$3/"*.c do n="$(basename \"$i\")" o="$2/$n.o" if chknam "$n" "$o" "$i"; then echo $c -o "$o" -c "$i" $c -o "$o" -c "$i" fi done } compile_c "Compiling Lu Objects" "${OBJ_DIR}" "${SRC_DIR}" compile_c "Compiling Lua Objects" "${OBJ_LUA_DIR}" "${SRC_LUA_DIR}"
