|

cbuild.sh: A simple, customizable, automated, and portable build script for C
|
||||
projects. This script works by automatically detecting .c source files in
|
||||
SRCDIR, generating a makefile, compiling them into objects in OBJDIR, and
|
||||
finally linking them to TARGET.
|
||||
|
||||
Customization:
|
||||
Open cbuild.sh in your editor and navigate to the USER CONFIG section (at
|
||||
the top of the file).
|
||||
|
||||
CC the compiler to use (default: gcc)
|
||||
CFLAGS compilation flags (default: -Wall -Wpedantic)
|
||||
LDFLAGS linker flags (default: none)
|
||||
LDLIBS linker libraries (default: none)
|
||||
TARGET final target to link (default: a.out)
|
||||
SRCDIR the directory where the script will search for .c source files
|
||||
(default: src)
|
||||
OBJDIR the directory where compiled objects will be placed. (default: obj)
|
||||
MAKEFILE the filename of the generated makefile (default: .makefile)
|
||||
|
||||
PKG_CONFIG_LIBS uses flags generated by pkg-config for the given library
|
||||
name.
|
||||
|
||||
HEADER_DIR the directory in which header files will be placed by the 'new'
|
||||
command. Note that this is relative to SRCDIR. Setting this to
|
||||
'.' means headers will be placed in the same directory as
|
||||
source files. Setting this to 'include' means headers will be
|
||||
placed in SRCDIR/include. (defualt: include)
|
||||
|
||||
Usage:
|
||||
./cbuild.sh [COMMAND]
|
||||
|
||||
COMMAND:
|
||||
--help display this help message
|
||||
build generate the makefile, compile objects and link target.
|
||||
clean remove makefile, objects, and target.
|
||||
buildcn clean, and then build.
|
||||
generate ONLY generate the makefile.
|
||||
run [ARGS] build, then execute TARGET with arguments ARGS.
|
||||
init equivalent to 'new module main' (see below).
|
||||
dryrun print all commands that will be executed during the build process
|
||||
to stdout.
|
||||
|
||||
new header [NAME] [...]
|
||||
generate a header file with name NAME in HEADER_DIR. Multiple
|
||||
NAMEs may be provided. Including '.h' in NAME is optional.
|
||||
|
||||
new module [NAME] [...]
|
||||
generate a new source file NAME.c in SRCDIR and a new header
|
||||
NAME.h in HEADER_DIR. Multiple NAMEs may be provided.
