编译TVM遇到 collect2: fatal error: cannot find 'ld'
在尝试编译TVM源码时,源码我在Ubuntu.上遇到了一个错误,安装具体是源码"collect2: fatal error: cannot find 'ld'"。这让我感到困惑,安装wdcp源码编译安装因为我已经确认ld已经被安装。源码
通过google搜索,安装郑州源码熊编程我检查了ld的源码安装路径,发现它确实存在。安装我尝试了重新安装binutils,源码使用命令"sudo apt install --reinstall binutils",安装但问题仍然没有解决。源码
我重新思考问题,安装发现cmake编译时使用的源码英雄传世源码链接器是lld,而不是安装官方推荐的ld。这可能是源码问题的关键。为了解决这个问题,长源码头砂石我安装了lld(使用命令"apt-get install lld"),然后重新编译,这次成功了。开源落地页源码
TVM建议使用llvm进行编译,因此链接器使用的是lld。这次的经验让我意识到,确认链接器版本和正确配置cmake参数对于编译过程至关重要。通过这个过程,我学到了如何在遇到编译问题时,系统地排查并解决问题。
