编译

我在尝试编译C项目时遇到问题。 我的文件夹包含一个.c，一个.h，我的库目录和一些文本文件。

使用我自己的main.c（gcc get_next_line.c main.c Libft/libft.a）手动编译时，每个人都可以正常工作。 我使用脚本来传递单元测试，这在我启动它时会给我这种类型的错误（出现的函数是我的库中用于我的.c的函数）。

在朋友的计算机上运行相同的脚本时，编译工作正常。 我没有把所有内容放在这里（我在这个脚本中使用的Makefile中有大量的代码），但是如果有人需要一些精确的话，我会很乐意尝试提供它们。

编辑：我会复制所有文本，我在尝试编译时得到了：

提前感谢您的帮助。

这两行是主要问题：

gcc -Wall -Werror -Wextra -ggdb -I includes -c srcs/**/*.c
ar rc libmt_framework.a *.o

推荐：

SRCS := $(WILDCARD srcs/*.c)
OBJS := $(SRCS.o:.c)

CFLAGS := -Wall -Wextra -Werror -ggdb 

NAME := libmt_framework.a

.PHONY: all
all: $(NAME)

*.o: *.c
<tab>gcc $(CFLAGS)  $< -o $@ -I./includes

$(NAME): $(OBJS)
<tab>ar -rcs $@ $^

创建可执行文件时应引用任何库。

有类似的东西：

$(EXECNAME): $(NEW_OBJS)
<tab>gcc -static -o $@ $^ $(LFLAGS) -LpathtoLibrary -lshortlibraryName
