只需要修改如图选项即可。菜单-》Project-》Make

## 2. IAR下使用.lib
和keil操作一致，直接添加进工程即可

## 3 SDCC生成.lib
调用 `sdar`生成.lib
```
Usage: sdar [-]{dmpqrstx} [--plugin <name>] archive-file file...
sdar -M [<mri-script]
commands:
d - delete file(s) from the archive
m - move file(s) in the archive
p - print file(s) found in the archive
q - quick append file(s) to the archive
r- replace existing or insert new file(s) into the archive
s - act as ranlib
t - display contents of the archive
x - extract file(s) from the archive
command specific modifiers:
- put file(s) after
- put file(s) before (same as )
- use zero for timestamps and uids/gids
- use actual timestamps and uids/gids (default)
- use instance of name
- truncate inserted file names
- use full path names when matching
- preserve original dates
- display offsets of files in the archive
- only replace files that are newer than current archive contents
generic modifiers:
- do not warn if the library had to be created
- create an archive index (cf. ranlib)
- specify the dependencies of this library
- do not build a symbol table
- deprecated, use --thin instead
- be verbose
- display the version number
@<file> - read options from <file>
--target=BFDNAME - specify the target object format as BFDNAME
--output=DIRNAME - specify the output directory for extraction operations
--record-libdeps=<text> - specify the dependencies of this library
--thin - make a thin archive
optional:
--plugin <p> - load the specified plugin
emulation options:
No emulation specific options
sdar: supported targets: asxxxx srec symbolsrec verilog tekhex binary ihex plugin
```
Makefile如下：
```makefile
ROOT_DIR := ../
TARGET = add
BUILD_DIR =./build/
#obj2占位符抵消../
BUILD_OBJ_DIR =./build/obj/obj2/
PREFIX =
CC = $(PREFIX)sdcc
AS = $(PREFIX)sdas8051 #sdc51
RM = -rm -rf
MAKE = make
MCU_MODEL = -mmcs51
MODEL= --model-large
CODE_SIZE = --code-size 65536# 64KB 的 Flash 存储器
IRAM_SIZE = --iram-size 2048 # 2KB 的内部 SRAM
XRAM_SIZE = --xram-size 32768 # 32KB 的内部扩展 RAM
AS_DEFS =
C_DEFS =
# includes,头文件必须包含在以下文件中
AS_INCLUDES =
INC_PATHS =\
-I$(ROOT_DIR)App \
-I$(ROOT_DIR)User \
-I$(ROOT_DIR)inc
# libraries
USER_SRC =$(ROOT_DIR)Library
C_SOURCES := $(USER_SRC)/add.c
# 对象文件
C_OBJECTS := $(patsubst %.c, $(BUILD_OBJ_DIR)/%.rel, $(C_SOURCES))
# 最终目标文件
ALL_OBJECTS := $(C_OBJECTS)
# 规则
.PHONY: all clean mk
# 主要目标
all: $(BUILD_DIR)/$(TARGET).lib
# 清理
clean:
-rm -rf $(BUILD_DIR)/*
# 编译
$(BUILD_OBJ_DIR)/%.rel: %.c
@echo "Compiling $< into $(dir $@)"
mkdir -p $(dir $@) | $(CC) -c -o $@ $(MCU_MODEL) $(INC_PATHS) $(MODEL) --out-fmt-ihx --debug $<
# 链接生成
$(BUILD_DIR)/$(TARGET).lib: $(ALL_OBJECTS)
@echo "Compiling $^ into $(dir $@)"
mkdir -p $(dir $@) | sdar rv $@ $^
# 删除构建目录
clean-build-dir:
rm -rf $(BUILD_DIR)
```
## 4 SDCC使用.lib
通过 `LDFLAGS`调用lib，-L包含lib库目录，-l链接指定lib
Makefile语法如下：
```makefile
ROOT_DIR := ../
TARGET = downloadfile
BUILD_DIR =./build/
#obj2占位符抵消../
BUILD_OBJ_DIR =./build/obj/obj2/
PREFIX =
CC = $(PREFIX)sdcc
AS = $(PREFIX)sdas8051 #sdc51
RM = -rm -rf
MAKE = make
MCU_MODEL = -mmcs51
MODEL= --model-large
CODE_SIZE = --code-size 65536# 64KB 的 Flash 存储器
IRAM_SIZE = --iram-size 2048 # 2KB 的内部 SRAM
XRAM_SIZE = --xram-size 32768 # 32KB 的内部扩展 RAM
AS_DEFS =
C_DEFS =
# includes,头文件必须包含在以下文件中
AS_INCLUDES =
INC_PATHS =\
-I$(ROOT_DIR)Driver/inc \
-I$(ROOT_DIR)User \
-I$(ROOT_DIR)Library
# libraries
LIBS = -ladd
LIBDIRS = -L../SDCC-lib/build
LIB_SRC =
USER_SRC =$(ROOT_DIR)User
C_SOURCES := $(wildcard $(ROOT_DIR)Driver/src/*.c$(ROOT_DIR)Driver/isr/*.c $(ROOT_DIR)App/src/*.c)
C_SOURCES += $(USER_SRC)/Main.c
ASM_SOURCES =
# 对象文件
C_OBJECTS := $(patsubst %.c, $(BUILD_OBJ_DIR)/%.rel, $(C_SOURCES))
ASM_OBJECTS := $(patsubst %.asm, $(BUILD_OBJ_DIR)/%.rel, $(ASM_SOURCES))
# 最终目标文件
ALL_OBJECTS := $(C_OBJECTS) $(ASM_OBJECTS)
# 链接选项
LDFLAGS =$(LIBDIRS) $(LIBS) # 删除未使用的段
# 规则
.PHONY: all clean mk
# 主要目标
all: $(BUILD_DIR)/$(TARGET).hex
# 清理
clean:
-rm -rf $(BUILD_DIR)/*
# 编译规则
$(BUILD_OBJ_DIR)/%.rel: %.c
@echo "Compiling $< into $(dir $@)"
mkdir -p $(dir $@) | $(CC) -c -o $@ $(MCU_MODEL) $(INC_PATHS) $(MODEL) --out-fmt-ihx --debug $<
$(BUILD_OBJ_DIR)/%.rel: %.asm
@echo "Compiling $< into $(dir $@)"
mkdir -p $(dir $@) | $(AS) -o $(INC_PATHS) $@ $<
# 链接规则
$(BUILD_DIR)/$(TARGET).hex: $(ALL_OBJECTS)
@echo "Compiling $^ into $(dir $@)"
mkdir -p $(dir $@) | $(CC) -o $@ $(MCU_MODEL) $(INC_PATHS) $(MODEL) $(CODE_SIZE) $(IRAM_SIZE) $(XRAM_SIZE) $(LDFLAGS) --out-fmt-ihx $^
# 删除构建目录
clean-build-dir:
rm -rf $(BUILD_DIR)
```

gpt的解释：
截图这样讲，我倒是有个疑问：STC发布的lib库文件应该是没有区分keil/SDCC/IAR的（下载的lib文件只有一种），不知道用什么编译器生成的？ 21cnsound 发表于 2024-12-3 21:15

只能keil下用吧

这个我之前有个帖子探究过
刚刚我调用最新的lib库,搞错一个东西.和大家分享一下我的错误 - 第2页 - C语言，汇编语言，Proteus MCU软件仿真 国芯技术交流网站 - AI32位8051交流社区
结论：STC发布的lib文件是 OMF51 格式的，只能被BL51和LX51这两款Keil PK51工具链里的链接器识别
至于Windows系统里的静态链接库，虽然也是.lib后缀，但那是完全不同的文件格式了
