-fPIC errors with --profile on Arch Linux

[RichardWarfield]

General summary/comments (optional)

This is likely related to #3518 and #3409 etc. But while users seem to have resolved those issues for GHC 8.2.2 and up, I see the same (or a similar) issue when using the --profile flag. Building without --profile works fine.

Steps to reproduce

stack build --profile --system-ghc (with Arch ghc-static package)
or
stack build --profile

Expected

The project should build without errors and with profiling data.

Actual

Linking fails with thousands of errors like these:

$ stack build --profile --system-ghc

Stack version

I have tried both 1.6.3 and the latest git master.

$ stack --version
Version 1.7.0, Git revision cd7ed8f44ea0ac0809ebc9125a05b0b7273765e9 (5683 commits) x86_64 hpack-0.21.2

Method of installation

I have tried:

• The official binaries
• The main Arch repository -- the stack and stack-bin packages

I have also tried various builds of GHC 8.2.2 (stack installed builds with ghc-build and tinfo6; as well as the ghc and ghc-static builds from the Arch packages). All exhibit this problem.

[borsboom]

Interesting that system GHC exhibits the same problem. Have you tried adjusting the GHC settings file (in <GHC-ROOT>/lib/ghc-<GHC-VERSION>/settings)?

[RichardWarfield]

I tried adding -fPIC to the system GHC settings (which I found in /usr/lib/ghc-8.2.2/settings).

 ("C compiler flags", " -fPIC -fno-stack-protector"),
 ("C compiler link flags", " -fPIC -fuse-ld=gold"),

Same result.

However -- I tried building a simple application (stack new teststack simple --system-ghc; stack build --system-ghc --profile) and this did work. So, the issue seems to relate to how my project is set up. Which is strange because I don't think there is anything at all funky about my .cabal or stack.yaml configuration. I'll try to isolate the issue now.

[RichardWarfield]

OK, this seems to have something to do with building a shared foreign library. By removing the below foreign-library stanza from my .cabal file, I can make the problem go away.

I have the same issue with a simple ghc build using arch :

echo 'main = putStrLn "toto"' > test.hs && ghc test.hs

result

I'm seeing the same sort of requires unsupported dynamic reloc 11; recompile with -fPIC errors on Alpine Linux (the alpine:latest docker image to be more precise)
