Build fails with "Can't use -fPIC or -dynamic on this platform"

Tener commented 11 years ago

I tried to run ./build on my Arch Linux, x86-64 PC. Lots of things compile but now it's failing at this line:

It looks like upstream changes have broken things. Will will have to remove the -fPIC option somehow because that is not supported on android afaik.

Ah, too bad. The commit that introduces this error message is from Oct 2012: http://www.haskell.org/pipermail/cvs-ghc/2012-October/076730.html

The code in question is: https://github.com/ghc/ghc/blob/master/compiler/main/DynFlags.hs#L3429

To be honest I'm not sure it does the right thing - the code is hard to read and I dont know what which flag mean.

Perhaps it simply doesn't take Android into account?

My last successful build was on 7th March. So that can’t be it. I think Ian Lynagh's clean-up of the build system a couple weeks ago changed something.

Probably commit 84df08debf13562f8a1fc7cd59054aaa9c379294

That was just a wild guess. What is your recommendation on how to get a working build?

neurocyte commented 11 years ago

You could try reverting https://github.com/neurocyte/ghc-android/commit/84df08debf13562f8a1fc7cd59054aaa9c379294

Tener commented 11 years ago

It didn't work unfortunately, nothing appear to have changed. I'll try with 7th March HEAD later.

Finally!

It took some nerves, but .... BUT ... it builds ... installs ... foreign-jni installs ... android-haskell-activity installs ... and works!!! Hooray!

My path to glory:

ubuntu 12.04 x86_64
llvm-3.0 from distribution
config.sub and config.guess must be from automake-1.13
used GHC commit b6a11fa08805f5b25493c63bc8c6a3085d48bb65. I don't know exactly, where it breaks, I'm too lazy to do git bisect. Some GHC commits had broken link to Cabal submodule, this one was the first that worked.
I had to copy GmpDerivedConstants.h manually, also mkGmpDerivedConstants binary did not build, so I could not generate GmpDerivedConstants.h in android device/emulator
I had to create opt and lld symlinks
after that the GHC compiled
cabal-install-0.14 from distribution
{1:0:11} does not work for some reason. It works in bash, but fails in configure. Changing configure she-bang to #!/bin/bash did not help. No idea. Also, --with-gcc was not forwarded to configure anyway (only --with-compiler was). Solved by hardcoding gcc path.

My greatest admiration to CJ!!!

Now it's time for me to step on the shoulder of giant and actually create something ... see you later.

I disabled dynamic linking in the build config, so it should work with the latest ghc head again (for now).
