Question

我已成功完成了安装位于this link的LLVM测试基础架构（LNT）的所有步骤。最后一步是执行以下命令：

lnt runtest nt \
    --sandbox SANDBOX \
    --cc ~/llvm.obj/Release/bin/clang \
    --test-suite ~/llvm-test-suite

我用我的值替换了命令，如下所示：

lnt runtest nt \
    --sandbox ~/mysandbox \
    --cc /opt/llvm/Debug+Asserts/bin/clang++ \
    --test-suite ~/llvm-test-suite

当我运行此命令时，我看到以下输出：

2013-05-16 14:43:27: checking source versions
2013-05-16 14:43:32: scanning for LNT-based test modules

nt.py:810: fatal error: nightly test failed, no report generated

我认为test log的以下代码段可能与它有关：

yacc -d /home/routemapper/llvm-test-suite/MultiSource/Applications/Burg/gram.y
make[4]: yacc: Command not found
make[4]: *** [y.tab.h] Error 127
yacc -d /home/routemapper/llvm-test-suite/MultiSource/Applications/Burg/gram.y
make[4]: yacc: Command not found

我知道为什么我可能会在示例LNT案例中收到此错误，即使我按照快速入门指南查看了这封信？

Answer 1

make[4]: yacc: Command not found

这应该给你提示。显然，您需要安装测试所需的yacc工具。如何安装将取决于您使用的平台。
