[gmx-developers] master branch link fails with clang 3.7/3.8/3.9

[Mark Abraham]

Hi,

Recent clang versions all work great for me in multiple places. ekinstate_t
acquired a destructor only recently, so if something is off in how your
build tree understands dependencies, that error would make sense.
Particularly if you tree is old, I suggest you make clean and try again.
