Makefile没有链接.o文件

我已经提供了以下Makefile来编译我的项目。它似乎是用相当老式的风格写的,虽然我正在阅读官方的GNU Make手册,但我无法修复它。项目本身似乎正确编译了所有.o文件,因为它在我的工作目录中创建了所有这些文件:main.o model.o param.o

# //////////////// NOMBRE DEL PROYECTO ///////////////////

EXE=$(P)
OBJS=main.o model.o param.o head.h

    bla=;
    for file in $(OBJS); do bla="$$bla ` $$file`"; done; \

.c.o:

.c.obj:
    $(CC) $(CFLAGS) $(INCL) -c -o $@ `if test -f '$<'; then '$<'; else '$(SRCDIR)/$<'; fi`

这是我收到的错误消息,但正如我所说,.o文件是在目录中创建的,但它似乎没有找到它们将它们链接到我的可执行文件中。

/bin/sh: 1: main.o: not found 
/bin/sh: 1: model.o: not found 
/bin/sh: 1: param.o: not found 
/bin/sh: 1: head.h: not found 
collect2: error: ld returned 1 exit status

答案 0 :(得分:1)

在for循环中,以下位不正确。

` $$file`

这是不正确的,因为.o文件不是为其输出运行的可执行文件。

这个makefile非常糟糕,你对此是正确的。

与上述问题相似。

除非$(COININCDIR)是要运行的命令,否则此行不正确。

INCL=-I\`$(COININCDIR)\`$(ADDINCFLAGS)

此错误是导致/bin/sh: 1: /installed/CoinAll/include/coin: Permission denied错误的原因。

此外,除非$(ADDINCFLAGS)旨在附加到$(COININCDIR)的值(几乎肯定不是这样),否则两个变量之间需要一个空格。
