競技プログラミング向けテスタ

なんかそのうちライブラリとかにうつしたい。

ソースの名前はmain.cppを仮定

入出力はhoge.in,hoge.outとする。

Makefile

CPP = clang++
CPP_FILE = main.cpp
TEST_SH = ./test.sh
CFLAGS = -O2 -std=c++11 -Wall

all: $(PROGRAM)

$(PROGRAM):$(CPP_FILE)
  $(CPP) $(CFLAGS) $(CPP_FILE) -o $(PROGRAM)

PHONY: check-syntax test

check-syntax:
  $(CPP) -fsyntax-only $(CFLAGS) $(CHK_SOURCES)

test:$(PROGRAM)
  $(TEST_SH) $(PROGRAM)

#!/bin/sh

# put test.sh ,input files and output files in the same folder.
# $ ls
