Question

所以我试图从this research paper运行开源代码，但我一直得到[make]错误2.感谢提供代码的makefile所以我所做的就是运行make命令当我在包含makefile的文件夹中时。

我是所有这一切的新手，我从互联网上得到了所有东西，所以如果我有点无知，我会道歉。我正在努力学习，请耐心等待（：

编辑:: 我已将其缩小到第36-44行的makefile，但写入的内容有问题。我很遗憾没有编写makefile的经验，所以我不知道如何修复它。我尝试弄乱一些行的缩进，因为其他一些线程似乎有这个问题，但无济于事。

Answer 1

include中缺少fluid2.h，NULL未定义。

调用

make OPT="-Wall -Os -include cstddef"

或添加

#include <cstddef>

到fluid2.h中的包含。

只需重写可怕的包含makefile就行了，试试这个：

CC       := g++
CPPFLAGS := -Isrc -Isrc/ann -Isrc/pcgsolver -MMD -MP
CXXFLAGS := -Wall -Os
LDFLAGS  := -framework OpenGL -framework GLUT

sources := $(wildcard src/*.cpp src/ann/*.cpp)
objects := $(sources:.cpp=.o)
deps    := $(objects:.o=.d)

flip2d: $(objects)
    $(LINK.o) $^ $(LDLIBS) -o $@

.PHONY: clean
clean: ; $(RM) $(objects) $(deps) flip2d

-include $(deps)

运行开源代码的makefile时出错2
