Building zlib fails #522

Closed andypotato closed 4 years ago

Error description

Using emscripten v1.39.17 on Ubuntu 18.04 results in a Permission error when trying to build zlib on first usage.

It seems the error is not related to file system permissions. I went as far as making the whole emsdk directory world readable/writable and running emcc as root. The error will still occur.

Error does no longer occur on a clean checkout of emsdk.
