Reverting to previous emsdk version #10220

Closed wini3d closed 4 years ago

wini3d commented 4 years ago

I tried updating to the latest version but the 1.35 prompt is throwing download errors so I decided to just start from scratch.

So I renamed my old installation and installed the new one on the same path c:/emscripten. Everything works well but I need to check back on my old installation, I renamed it back and now I am getting LLVM errors that I have tested from the latest version is showing up on my old 1.35 which did not exist when before updating to latest.

renamed back the .emscripten-old in my home folder that was set during my latest installation and still throwing the latest version errors.

Can you should the actual errors you are seeing. Also can you show the download error?

Does emcc --clear-cache after you rename fix the issue?

Thanks actually I think it is normal as the 1.35 came from an offline windows installer.

I am concerned about getting back my previous installation and just think about switching back and forth later.

It seems my llvm/clang or other tools has been updated when I installed the latest 1.39.

Even when I reinstalled the offline 1.35 installer, I noticed longer compile times and a lot of warnings that did not show before like these:

WARNING:root:generating system library: libcxx_noexcept.a...
WARNING:root:                                               ok
WARNING:root:generating system library: libcxxabi.bc...
WARNING:root:                                          ok

WARNING:root:                                     ok

WARNING:root:

What specific tool is generating those warnings? and how can I revert back to my previous emscripten 1.35 build tools?

sbc100 commented 4 years ago

Those warning about generating system libraries should only occur the first time you use emscripten, or whenever you switch versions. They are normal and expected.

Thanks for the info. I figured the older version was garbled anyway and can't reproduce how it was working that way. Anyway, better to move forward with the latest emsdk version.

thanks again.
