[SOLVED] Bash multiple include/source problem

Michal Krzyz · 12-10-2012, 05:24 AM

Hello

I am writing installation script with following files' hierarchy:

build_scripts/
build_scripts/build_all.sh <- should contain source config.in
build_scripts/temporary_toolchain/build_all.sh <- should contain source config.in
build_scripts/system_build/build_all.sh <- should contain source config.in
...

build_scripts/config_files/
build_scripts/config_files/config.in <- should contain source error_handler.in source paths.in etc.
build_scripts/config_files/error_handler.in <- should contain output_messages.in
build_scripts/config_files/output_messages.in
build_scripts/config_files/paths.in
...

how can I include config.in from any build_all.sh script and then from config.in include for example paths.in knowing only relative path between config.in and paths.in.
HINT: relative path between script including config.in and config.in path depends on path of currently executing build script

Is there any nice solution?

I found one which is not very nice: call each build script from one path (for example build/) and then use relative path between build/ and each included script.

I found one solution. It is not very nice because each included script should contain couple lines of code, but it works.

This link was helpful
http://stackoverflow.com/questions/5...-its-stored-in

finally I added following code to each included file:

Code:

SOURCE="${BASH_SOURCE[0]}"
DIR="$( dirname "$SOURCE" )"
while [ -h "$SOURCE" ]
do 
  SOURCE="$(readlink "$SOURCE")"
  [[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE"
  DIR="$( cd -P "$( dirname "$SOURCE"  )" && pwd )"
done
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"

And I am doing this kind of stuff in the config.in:

Code:

#!/bin/bash

function find_current_script_dir()
{
  SOURCE="${BASH_SOURCE[0]}"
  DIR="$( dirname "$SOURCE" )"
  while [ -h "$SOURCE" ]
  do
    SOURCE="$(readlink "$SOURCE")"
    [[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE"
    DIR="$( cd -P "$( dirname "$SOURCE"  )" && pwd )"
  done
  echo "$( cd -P "$( dirname "$SOURCE" )" && pwd )"
}

LFS_BUILD_CONFIG_SCRIPTS_DIR="$(find_current_script_dir)"

source $LFS_BUILD_CONFIG_SCRIPTS_DIR/output_messages.in
source $LFS_BUILD_CONFIG_SCRIPTS_DIR/error_handling.in
source $LFS_BUILD_CONFIG_SCRIPTS_DIR/paths.in

and in similar way I included output_messages.in in error_handling.in
