As of 7.10.3 these are largely fixed. Could you try the 7.10.3 release candidate? For the record, the testsuite summary should look something like this on 7.10.3, {{{ OVERALL SUMMARY for test run started at Tue Nov 3 02:48:37 2015 KST 0:46:50 spent to go through 4463 total tests, which gave rise to 18087 test cases, of which 14064 were skipped 52 had missing libraries 3906 expected passes 41 expected failures 6 caused framework failures 0 unexpected passes 11 unexpected failures 13 unexpected stat failures Unexpected failures: cabal/sigcabal01 sigcabal01 [bad stderr] (normal) codeGen/should_compile T7574 [stderr mismatch] (normal) driver T5313 [bad stderr] (normal) ghc-api T8628 [bad stderr] (normal) ghc-api T8639_api [bad stderr] (normal) ghc-api/T10052 T10052 [bad stderr] (normal) ghc-api/dynCompileExpr dynCompileExpr [bad stderr] (normal) rts T5435_v_asm [bad stderr] (normal) rts T5435_v_gcc [bad stderr] (normal) rts linker_unload [bad stderr] (normal) safeHaskell/flags Flags02 [exit code non-0] (normal) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11055#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

#11055: GHC 7.8.4 crash on ARM while building Stack 0.1.7 ---------------------------------------+---------------------------------- Reporter: Lokathor | Owner: Type: bug | Status: infoneeded Priority: normal | Milestone: Component: Compiler | Version: 7.8.4 Resolution: | Keywords: Operating System: Linux | Architecture: arm Type of failure: Compile-time crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------------+---------------------------------- Comment (by Lokathor): Alright, I guess the downloads directories are made before they're filled, and they're filled based on platform popularity as well. At the time of this writing, the 7.10.3-rc1 directory has an ARM build, the 7.10.3-rc2 does not, and the 7.10.3-rc3 directory is entirely empty. Using 7.10.3-rc1 I was able to build stack 0.1.7, and it seems to work. I also tried out another file that would always crash GHCi (but not GHC) in version 7.8.4, and using version 7.10.3-rc1 it did not crash ghci. I did however get a warning I've never seen before during the linking, about missing mapping symbols. I built another project just to be sure and it gave the same thing, all the messages are basically {{{ /usr/bin/ld.gold: warning: cannot scan executable section 1 of /home/daniel/dev/haizod/.cabal-sandbox/lib/arm-linux- ghc-7.10.2.20151030/netwo_EsGuXlNmVtd2gsY9SXPuBb/libHSnetwork- simple-0.4.0.4-G2iPUu3gNst2JPWvkDR4bl.a(TCP.o) for Cortex-A8 erratum because it has no mapping symbols. }}} Things *seem* to run fine despite the warning though. I'm going to use the newly built stack to rebuild stack itself, which should give it a fair shake, but it takes like a day to build all the dependencies and the binary together, so I'll get back on results from that tomorrow. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11055#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Thanks for reporting and testing. Great to know that stack works on arm now. Check #10376 for those warnings. Workaround: set `library-stripping: False` in `~/.cabal/config`.
