我有一个C-Code，用一些Linux Derivation编写，我想把它移植到Windows中。
我对Makefile做了一些修改，并使用mingw32-make来编译它们。
生成的执行文件工作正常，直到我看到结果
该程序用于进行一些数据分析，并且应该产生一个介于20和100之间的数字列表。对于一个示例数据，应该有大约48.442的3个数字。
但是，当我运行Windows可执行文件时，我得到3个数字大约292136359165898530000000000000000000000000000.000
然后我安装了virtualbox并尝试使用“make”作为console-command运行原始的Makefile，但它抱怨说，虽然插入了-lm，但是没有请求math-libary（pow undefined等）。每个gcc命令。

我不得不说，我通常不会那样直接编译。
通常我会让一些具有正常工作默认设置的GUI来安慰自己。这可能就是我错过了一些基本的东西的原因。
你能否告诉我为什么windows-executable正在处理数字错误以及为什么我在ubuntu中编译失败？

编辑： 执行windows / linux可执行文件的问题是我使用windows将文件列表作为输入文件。该程序有一个简单的文件名列表可供搜索。但是，C不喜欢\ r \ n，但只有\ n，因此它随机出现在数字和文件名上的尾随\ r \ n。 Windows makefile正在运行，linux-makefile已经过时，文件顺序错误等。
答案 0 :(得分：2)
您的Linux Makefile错误（它将-lm传递给chmod命令，但-lm应作为链接gcc命令的最后一个参数传递）。请记住，gcc的程序参数顺序非常重要。
你真的不需要chmod命令，如果你这样做，它应该在Makefile <的单独的行上/ p>
您应该运行make -p一次，以了解make已知的内置规则。
尝试类似
的内容 CC= gcc
CFLAGS= -g -Wall
LDLIBS= -lm
SOURCES= extract_timestamps.c filename_treatment.c basic_analysis.c \
collection.c read_lecroy_file.c read_tek_file.c \
stamp_handling.c treat_lecroy_file.c treat_tek_file.c \
save_timestamps.c injection_statistics.c calc_time_stamp.c \
peak_finding.c get_timestamps.c
OBJECTS= $(patsubst %.c, %.o, $(SOURCES))
.PHONY: all clean
all: extract_timestamps
extract_timestamps: $(OBJECTS)
$(LINK.c) $^ $(LOADLIBES) $(LDLIBS) -o $@
## add or autogenerate rules for object files.
在适当的时候用一个 tab 字符替换上面的多个空格。
上述Makefile仍然不完整。您需要完成它（并且您需要一个clean目标）。见this example。您可能需要：
%.o: %.c time_ext.h
顺便说一句，我不建议在您的案例中使用Makefile生成器，例如cmake。您的程序非常简单，可以通过普通Makefile
通过GUI编译是一个坏习惯（您可以在M-x compile中尝试emacs）：GUI工具正在运行命令来构建您的程序，它正在隐藏它们。所以当出现问题时你会变得无助。熟悉Linux命令，它们非常有用！
Windows和Linux可执行文件之间的不同行为（对于相同的源代码）可能有很多原因：undefined behavior，实现floating point的不同方式 - 实现不仅依赖于处理器，但依赖于操作系统，不同的x86 calling conventions，不同的编译器版本。编写portable代码是一项困难的艺术。
改进您的代码，直到您没有收到任何警告且编译器没有错误（例如gcc -Wall）
