我在ubuntu 19上安装watchman时出错，有人能给我一个解决方案吗？

Question

我遵循守望者的官方指南克隆守望者，并遵循给定的命令。

$ cd watchman

$ ./autogen.sh

$ ./configure

$ make 

在$ make命令之后，它导致了如下错误

  CXX      scm/watchman-Mercurial.o
scm/Mercurial.cpp: In constructor ‘watchman::Mercurial::infoCache::infoCache(std::string)’:

scm/Mercurial.cpp:16:40: error: ‘void* memset(void*, int, size_t)’ clearing an object of non-trivial type ‘struct watchman::FileInformation’; use assignment or value-initialization instead [-Werror=class-memaccess]

   16 |   memset(&dirstate, 0, sizeof(dirstate));
      |                                        ^

      |        ^~~~~~~~~~~~~~~

make: *** [Makefile:4446: scm/watchman-Mercurial.o] Error 1

有人知道这是怎么回事吗？

将这些标志添加到配置中(在make之前)为我做了这件事：

./configure --without-python  --without-pcre --enable-lenient
