铿锵makefile“ar：没有指定存档成员”

我重构了一些C代码，我尝试将它编译为mac上的clang而不是linux上的gcc。铿锵makefile“ar：没有指定存档成员”

首先，如果我只是运行make命令我在第一个文件编译得到了一个错误：
+++ Compiling [sys_msg.c] clang: error: unsupported argument '-adhlns=../../src/sys_msg.lst' to option 'Wa,'

所以我删除了-Wa,-adhlns=$(<:.c=.lst)选项创建此错误。

之后，一切似乎编译，但最后.a文件的程序集失败，我不明白为什么。

这里是我的化妆输出：

为什么铛鼓舞了我呢？

感谢对@MadScientist 我明白为什么我有这样的错误，如果我在我的化妆我有打印的东西：

我的错误来为我的生成文件的这一部分：

PROJ_ASRCS = $(filter %.s,$(foreach file,$(SOURCES),$(file))) 
PROJ_ASRCS += $(filter %.S,$(foreach file,$(SOURCES),$(file)))

我不想包含所有.o因为我做了多个编译，我只想列出所需的文件。

我有和ExperimentalCore-sam项目相同的编译过程。

我该怎么做？

您的循环'$（的foreach文件，$（源），$（文件））'没有做任何事情;你正在循环查看'SOURCES'中的每个单词，并且每个单词都将其展开为该单词......这是一种非常耗费资源的方式来恢复原始列表。除非你试图做一些非常棘手的双重评估事情。 – MadScientist

是的，这是因为我用不同的文件版本编译不同的lib。我不想包含所有对象。我使用与此项目相同的构建系统：[ExperimentalCore-sam]（https://github.com/aethaniel/ExperimentalCore-sam） –

对不起，但我不理解您的评论或与我的相关内容。我只是说'$（foreach file，$（SOURCES），$（file））'不过是编写'$（SOURCES）'的非常低效的方式。你会得到相同的结果。您循环访问'$（SOURCES）'的值，并为列表中的每个元素获取相同的元素。 – MadScientist

我只能假设变量AOBJS为空。回到创建它的位置后，我只能假设这意味着您的SOURCES变量中没有列出.s或.S文件。

你为什么不跑的$(AR)单一的调用和只使用$^自动变量，并筛选出.o文件，而不是$(AR)命令的三种不同的调用？

$(AR) -rv $(OUTPUT_FILE_PATH) $(filter %.o,$^)

编辑要清楚我建议您在输出目标规则改成这样：

$(OUTPUT_FILE_PATH): $(OBJ_PATH) ../rules.mk ../sources.mk $(HAL_PATH)/Makefile $(AOBJS) $(COBJS) $(CPPOBJS) 
     $(AR) -rv $(OUTPUT_FILE_PATH) $(filter %.o,$^) 
     $(NM) $(OUTPUT_FILE_PATH) > $(HAL_PATH)/$(OUTPUT_NAME)_symbols.txt

或者，如果你想成为更习惯用法正确：

$(OUTPUT_FILE_PATH): $(OBJ_PATH) ../rules.mk ../sources.mk $(HAL_PATH)/Makefile $(AOBJS) $(COBJS) $(CPPOBJS) 
     $(AR) -rv [email protected] $(filter %.o,$^) 
     $(NM) [email protected] > $(HAL_PATH)/$(OUTPUT_NAME)_symbols.txt

与上面一样，我一定会从必备项列表中删除$(OBJ_PATH)。

我这样做是因为我不想在这个库中包含所有'.o'，所以SOURCES列表中确实没有包含任何.s或.S。 –

如果SOURCES列表中不包含任何'.s'或'.S'文件，那么'AOBJS'的值将是空的（因为我们发现：这就是导致原始问题的原因），所以'$（ AOBJS）'在先决条件列表中将是空的，所以'$ ^'自动变量的值将不包含任何对象。我的改变给你以前的行为。 – MadScientist

我了解GCC和Clang之间的区别。

使用GCC如果您运行的ar命令没有指定存档成员，他只是跳过这一步。 Clang在这种情况下提出错误并停止构建。

修补它我只是检查，如果我的列表为空或不：

$(OUTPUT_FILE_PATH): $(OBJ_PATH) ../rules.mk ../sources.mk $(HAL_PATH)/Makefile $(AOBJS) $(COBJS) $(CPPOBJS) 
ifneq ($(strip $(AOBJS)),) 
    $(AR) -rv $(OUTPUT_FILE_PATH) $(AOBJS) 
endif 
ifneq ($(strip $(COBJS)),) 
    $(AR) -rv $(OUTPUT_FILE_PATH) $(COBJS) 
endif 
ifneq ($(strip $(CPPOBJS)),) 
    $(AR) -rv $(OUTPUT_FILE_PATH) $(CPPOBJS) 
endif

我真的不明白为什么你不想在下面使用我建议的解决方案。它更简单，更高效，因为你只调用一次'ar'而不是三次。 – MadScientist

你的建议是更通用的建议，但在我的情况下，我必须选择我的档案成员。我每次都用不同的输入文件多次运行这个makefile。我不想在此存档中添加冲突的二进制文件。 –

看到我上面的评论。你的makefile在任何情况下的行为都与我的行为相同。 – MadScientist
