During Manual Installation, an encoding error: `commitAndReleaseBuffer`: invalid argument (invalid character)

[freckletonj]

TL;DR : en_US.UTF-8 vs C.UTF-8

I've solved this as being an error of the environment's LANG encoding, but it'd be nice if this were documented.

Problem:

$ stack ./install.hs hls-8.8.4
<<<...>>>
ghc-lib                          > Registering library for ghc-lib-8.10.4.20210206..
<stderr>: commitAndReleaseBuffer: invalid argument (invalid character)

<stderr>: commitAndReleaseBuffer: invalid argument (invalid character)
Progress 8/162

Solution:

$ echo $LANG
en_US.UTF-8

$ LANG=C.UTF-8 stack ./install.hs hls-8.8.4

wow, thanks for reporting the issue, i would say it should work with en_US.UTF-8, have you tried to install ghc-lib-8.10.4.20210206 in isolation with the original LANG definition?

[freckletonj]

I haven't, if I installed that separately, would the stack ./install.hs know how to link to it instead of recompiling it itself?

[jneira]

If you execute stack install ghc-lib-8.10.4.20210206 --stack-yaml=stack-8.8.4.yaml i think it will not recompile it. Nevertheless the test could be used to open an issue upstream.

install.hs is dead.
