修改 makefile
我有来自 PARSEC 开源基准测试的以下文件，我希望能够使用 gcc 对其进行分析。但正如你所知，我需要提高 -pg 标志。但我这样做有困难。我尝试使用常规 g++ -pg -o files.cpp 但它不起作用。我还尝试修改在 -oi 前面放置 -pg 的 makefile，但它也给出了巨大的错误。所以现在我陷入困境，要么我做错了什么，要么 -pg 标志需要一些特殊的东西......但是单独执行时 makefile 给了我一个输出，我通过运行测试了它，它是成功的！所以我确信我的编译器接受源代码
# Makefile for parallel simulated annealer
PREFIX=${PARSECDIR}/pkgs/kernels/canneal/inst/${PARSECPLAT}
TARGET=canneal
LIBS:=$(LIBS) -lm
ifdef version
ifeq "$(version)" "pthreads"
CXXFLAGS+=-DENABLE_THREADS -pthread
endif
endif
all:
$(CXX) $(CXXFLAGS) annealer_thread.cpp -c -o annealer_thread.o
$(CXX) $(CXXFLAGS) rng.cpp -c -o rng.o
$(CXX) $(CXXFLAGS) netlist.cpp -c -o netlist.o
$(CXX) $(CXXFLAGS) main.cpp -c -o main.o
$(CXX) $(CXXFLAGS) netlist_elem.cpp -c -o netlist_elem.o
$(CXX) $(CXXFLAGS) $(LDFLAGS) *.o $(LIBS) -o $(TARGET)
clean:
rm -f *.o $(TARGET)
install:
mkdir -p $(PREFIX)/bin
cp -f $(TARGET) $(PREFIX)/bin/$(TARGET)
I have the following file from the PARSEC opensource benchmarks, and I want to be able to profile it using gcc. yet as u know i need to raise the -pg flags. yet i am having difficulties doing so. i tried to use a regular g++ -pg -o files.cpp yet it didnt work. i also tried to modify the makefile that infront of the -o i placed a -pg yet it also gave huge errors. So now i am stuck, either I did something wrong or the -pg flags require something special...yet the makefile when executed alone gave me an output which i tested by running and it was successfull! so i am sure the source code is accepted by my compiler
