使用 LLVM 16.0.4 编译 MiBench 中的 tiff-v3.5.4 时遇到编译链接错误

错误信息如下

这是一个编译链接错误，主要问题是链接器找不到数学库中的函数（如sqrt、exp、log等）。

错误类型：链接阶段未定义的引用（undefined reference）
缺失的函数：sqrt、exp、log等数学函数
问题原因：编译时没有链接数学库（libm）
解决方案：在编译命令中添加-lm选项来链接数学库

我的解决方案：

编辑mibench-master/consumer/tiff-v3.5.4/tools/Makefile
修改CFLAGS，在最后加上-lm

COPTS = -std=gnu89 -O0 -Xclang -optnone -g -fno-discard-value-names -w
OPTIMIZER=
IPATH = -I. -I ${SRCDIR} -I$ {LIBDIR}
CFLAGS = ${COPTS}$ {OPTIMIZER} ${IPATH} -lm
