Open the file ls.cc (in my case, it was ls.h) in [backcolor=var(--black-200)]ns-2.xx/linkstate directory. Change the 137th line ie. as follows from


[color=var(--black-600)][backcolor=var(--highlight-bg)]void eraseAll() { erase(baseMap::begin(), baseMap::end()); }
[backcolor=var(--highlight-bg)]

[color=var(--black-600)][backcolor=var(--highlight-bg)]to
[backcolor=var(--highlight-bg)]

[color=var(--black-600)][backcolor=var(--highlight-bg)]void eraseAll() {baseMap::erase(baseMap::begin(), baseMap::end()); }
