|
||||
This is a modular script to build C++ programs without any make or build tools.
|
||||
|
||||
This script is designed to run using a build-settings.rc file containing settings,
|
||||
or by having all of the settings set in the environment.
|
||||
|
||||
To run this script without bash, your shell must be able to process bash-style "if" syntax as used here.
|
||||
|
||||
|
||||
Settings:
|
||||
SRC_PATH is the full path to the repository's source code.
|
||||
|
||||
IN_FILES should be a space-separated list of cpp files not including the extension.
|
||||
The full path to each file must not include spaces, but the path must be
|
||||
relative to the SRC_PATH (since the filenames are collected in a bash
|
||||
string then used as the input param for g++).
|
||||
If the file is in a subdirectory, you must also specify the name of the
|
||||
directory in OTHER_DIRS so a corresponding directory under the objects
|
||||
directory gets created (or you simply do that and not specify the subdir
|
||||
here, and that option will cause the file to be found--see OTHER_DIRS
|
||||
below).
|
||||
|
||||
BIN_NAME is the filename for the binary to compile.
|
||||
|
||||
OTHER_DIRS is a list of other subdirectories where files may exist.
|
||||
The filenames (without extension) must not be the same as in any other
|
||||
folder (since this script places all o files in the same directory).
|
||||
Each directory must be free of spaces since it is iterated based on spaces.
|
||||
Any matching file in such a directory will override the file in the SRC_PATH
|
||||
directory if the file name is the same, so there will be no conflict in that
|
||||
case, but the file in the SRC_PATH will be ignored.
|
||||
|
||||
|
||||
DIST_FILES (optional) is a space-separated list of files or directories that should
|
||||
be copied to the build directory along with the binary. This is for
|
||||
required files that should be distributed with the program.
|
||||
|
||||
BUILD_DIR (optional, default is "build") is the directory to place the binary
|
||||
executable and DIST_FILES if any.
|
||||
|
||||
Example build-settings.rc:
|
||||
SRC_PATH="$REPO_PATH/src"
|
||||
IN_FILES="Application ApplicationDelegate IrrlichtEventReceiver main SaveFileDialog"
|
||||
BIN_NAME=my_program
|
||||
OTHER_DIRS="extlib"
|
||||
|
||||
With the correct use of a build-settings.rc file,
|
||||
This script is identical in every project.

||||
