私はlinuxのmakefileの使い方を学ぼうとしています。リンクする前にメークファイルクリーニングオブジェクトを防ぐ方法(-jオプションを使用)
私は次の2つのファイルがあります。
makefile.config
# Project Configurations
# Project Name
PROJECT_NAME = myapp
# Project Version
PROJECT_VERSION = 0.1
# Program or Shared Library
IS_LIBRARY = no
# Source Files Directory
SRC_DIRECTORY = src
# Header Files Directory
INC_DIRECTORY = inc
# Library Header Files Directory
LIB_DIRECTORY = lib
# Build Output Directory
BIN_DIRECTORY = ../Executable
# Installation Directory Exec
INS_DIRECTORY = /usr/local/bin/
# Installation Directory Headers
INS_HEARERS_DIRECTORY = /usr/local/include/
# Installation Directory SO
INS_SO_DIRECTORY = /usr/local/lib/
# C Flags
CFLAGS = -O3 -D_GNU_SOURCE -Wfatal-errors
# C++ Flags
CXXFLAGS = $(CFLAGS)
# Linker Flags
LDFLAGS = $(shell dpkg-buildflags --get LDFLAGS)
# Linker Libraries
LDLIBS = -fno-inline
# Debug Yes/No
DEBUG = yes
# C Compiler
CC = gcc
# C++ Compiler
CXX = g++

すべてがうまく、少なくとも私はそれを使用しています何のために...完璧な作品をしかし、makefileを-jオプションで実行しようとすると(例)
$ make -j4
プロシージャは、オブジェクト(.o)をリンクする前にそのオブジェクトをクリーンアップします。
[email protected]:Source Code$ make -j4

この問題を解決するにはどうすればよいですか? (オブジェクトがステップをリンクする前に実行するステップのクリーニング防ぐ)
ありがとうございます。あなたは正しいです。毎回実行後にオブジェクトを削除しないでください。 – iikem
