<br>
I’m sorry if this is not the right list to ask, I was unsure.<br>
<br>
I’m having problems compiling a project with stack on a Gentoo machine.<br>
I only have shell access to the machine, so I don’t have too much info about it,<br>
but the admin assured me that everything is up to date.<br>
<br>
I’ve upgraded to the latest stack, but the problem was also present with 0.1.4.<br>
While doing stack build on my project with resolver lts 3.10 I get the following<br>
strange error:<br>
<br>
----------------------------------------------------------------------------------------------<br>

----------------------------------------------------------------------------------------------<br>
<br>
<br>
Note that the warnings are not stopping the compile process themselves, but they somehow trigger the last error which kills the compiler.<br>
<br>
Stack is using the system-installed GHC here, which is version 7.10.2 (of course, otherwise stack wouldn’t have selected it).<br>
Maybe the system-wide compiler wasn’t installed properly (I doubt it, since the admin told me<br>
he uses a Gentoo package manager which is written in haskell and everything works well).<br>
So I’ve tried installing a stack-local GHC version, but I get a sanity check error:<br>
<br>
----------------------------------------------------------------------------------------------<br>
The GHC located at /home/gigabytes/.stack/programs/x86_64-linux/ghc-7.10.2/bin/ghc failed to compile a sanity check. Please see:<br>
<br>
<a href="https://github.com/commercialhaskell/stack/blob/release/doc/install_and_upgrade.md" rel="noreferrer" target="_blank">https://github.com/commercialhaskell/stack/blob/release/doc/install_and_upgrade.md</a><br>
<br>
for more information. Exception was:<br>
Running /home/gigabytes/.stack/programs/x86_64-linux/ghc-7.10.2/bin/ghc /tmp/stack-sanity-check22752/Main.hs -no-user-package-db exited with ExitFailure 1<br>
[1 of 1] Compiling Main ( /tmp/stack-sanity-check22752/Main.hs, /tmp/stack-sanity-check22752/Main.o )<br>

----------------------------------------------------------------------------------------------<br>
<br>
<br>
So to recap:<br>
- The system-wide ghc crashes compiling transformers-base-0.4.4<br>
- The stack-local ghc does not pass a sanity check<br>
<br>
<br>
On an OS X machine, the project compiles and work very well with the same<br>
stack and ghc versions and the same LTS, so I suppose this has to do with<br>
Gentoo.<br>
<br>
Any ideas?<br>
<br>
Thank you,<br>
