meta-build

Introduction

meta-build is my attempt at writing a simple meta-build system that uses the Ninja build system.

Features

• Recursive directory traversal for finding source (.c) and header (.h) files.
• Uses most popular and recommended compiler-flags.
• Uses most popular and recommended linker-flags.
• User can pass compiler-flags as arguments.
• User can pass linker-flags as arguments.
• User can pass executable/library name as argument.

Examples

Running meta-build --cflags -g --ldflags -lm --executable using Lua's source code produces the following build.ninja file:

cflags = -O2 -Wall -Wextra -Wformat -Wformat=2 -Wconversion -Wsign-conversion -Wtrampolines -Wimplicit-fallthrough -Wbidi-chars=any -Werror=format-security -Werror=implicit -Werror=incompatible-pointer-types -Werror=int-conversion -fstrict-flex-arrays=3 -fstack-clash-protection -fstack-protector-strong -fcf-protection=full -fno-delete-null-pointer-checks -fno-strict-overflow -fno-strict-aliasing -ftrivial-auto-var-init=zero -fexceptions -g -fPIE -pie -I/home/omega/Git/meta-build
ldflags = -Wl,-z,nodlopen -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now -Wl,--as-needed -Wl,--no-copy-dt-needed-entries -lm
