However, when I run this, I get an error - "undefined reference to cos". I am using the cosine functions in my program, but I have already linked the library to the compilation of those two files. I thought about adding "-lm" to the first clang option as well. This led to no er...
Ilinux编译出现undefinedreferencetocos 错误缘由主要是没有定义 sin函数,或者说没有找到 sin函数的实现,虽然我们在函数开始声明白数学函数库,但还是没有找到sin的实现,这时我们就需要指定sin函数的详细路径了。 在指定详细路径之前,我们固然需要知道这个所谓的详细路径在哪? 技巧:函数的查找办法如下: [root@lybroot]nmo...
今天,在编译一段代码时,出现错误 “undefined reference to cos” 但是,该文件已经包含了math.h头文件,错误原因主要是没有定义“cos”函数,或者说没有找到“cos”函数的实现,虽然我们在函数开头声明了数学函数库,但还是没有找到cos的实现,这时我们就需要指定sin函数的具体路径了。 系统一些默认库的位置在/lib/下面...
在使用“ - l”参数时,通常的习惯是出去“lib”函数库头和后面的版本号,使用真名和参数“-l”连接,形成“- lm”。于是,我们需要在gcc找不到库时,可是使用“-l”直接给定库名,输入如下: [root@lyb root]# gcc –o 1-6 1-6.c -lm 就可以正确编译了! 转自:http://blog.sina.com.cn/s/blog_643d...
编译的时候带上参数 -lm 如:gcc -o myproc myproc.cpp -L/usr/lib -lm
您是用gcc编译的么?加上-lm编译选项试试。此外,这是c++代码,我建议您 include <cstdlib> include <cmath> include <cstdio>
I have included the -lm in linking command but I am still getting he following undefined references: undefined reference to __libm_sse2_sin undefined reference to __libm_sse2_sincos undefined reference to __libm_sse2_pow Does anyone know how to resolve this? According to m...
当使用gcc编译器编译含数学函数的C程序时,会出现undefined reference to `sin'等错误.这种错误一般是由于缺少库造成的. (base) xiao@xiao-Inspiron-7590:~/Desktop/SDK_2.4.1/test/test0$ gcc get_distance.c -o get_distance /usr/bin/ld: /tmp/ccP8GXmr.o:infunction`hav':get_distance.c:(.text+0x...
