haste-boot hangs in ghc-prim with no output

[WolframKahl]

Trying to use 0.6.0.0 from github, I encounter a situation where haste-boot appears to hang, at 100% CPU, while attempting to process ghc-prim. I have had it running for hours, with no difference: All the output I get is:

 $ haste-boot --local --with-haste-cabal=$(which haste-cabal)
Downloading Google Closure compiler...
Reading package info from "libraries/rts.pkg" ... done.

What I can easily find out about the running process:

$ ps ucax | grep 28927
kahl     28927 99.6  0.0  13744  2732 pts/129  R+   11:22   5:50 haste-cabal.bin

Hitting Ctrl-C on the haste-boot process gives me:

(This time I needed to hit Ctrl-C twice.)

I suspected that some of these messages were held back due to buffering issues, and tried:

However, this makes no difference.

I previously had occasional access with haste-boot, but unfortunately cannot reproduce that now.

The main issue I see is that the process keeps running at 100% CPU for hours even though it presumably is already in an error state.

(Aside: Is it possible that somewhere a dependence on monads-tf is missing? I had messages about that; then did cabal install monads-tf, and then did not get those anymore so far.)

It is now making progress: After

cd haste-compiler
cabal install

I first did

cd libraries
cd haste-prim
cabal install

cd ../haste-lib
cabal install

before doing

cd ../..
haste-boot --local --with-haste-cabal=$(which haste-cabal)

If this is the right procedure, the documentation should presumably be updated.

[valderman]

Which GHC version are you using? I can't reproduce this on 7.10, and 8.0 support is still in the pipeline.

[WolframKahl]

Always 7.10.

I have since discovered that:

• haste-boot clobbers haste-cabal, so that needs to be re-installed in case of a haste-boot re-try.
• For real re-start of haste-boot, it seems to be necessary to

rm -rf ~/.haste/x86_64-linux-haste-0.6.0.0-ghc-7.10.3

• Before haste-boot, GHC-installation of the libraries is necessary:

cd haste-compiler
cabal install

cd libraries/haste-prim
cabal install

cd ../haste-lib
cabal install

How can I replace ~/.haste with a global installation path?

One one machine I am behind a firewall, and cannot connect to the Internet: It would be nice to be able to give haste-boot options pointing to a pre-downloaded JS compiler so that it still can do a full installation without Internet connection. (I am installing everything from source.)
