GHC looks for paths in the build environment (which do not exist when it is running) #9

Closed luispedro closed 3 years ago

luispedro commented 5 years ago

Compiling a simple test fails (this is on a fresh env with only GHC installed):

[1 of 1] Compiling Main             ( Main.hs, Main.o )

<no location info>: error:
    Warning: Couldn't figure out C compiler information!
             Make sure you're using GNU gcc, or clang
ghc: could not execute: /home/conda/feedstock_root/build_artifacts/ghc_1546296476453/_build_env/bin/x86_64-conda_cos6-linux-gnu-cc

I believe the issue is that the settings file installed with ghc lists paths from the build environment, which (obviously) do not exist on my machine. Here is the lib/ghc-8.2.2/settings file:

[("GCC extra via C opts", " -fwrapv -fno-builtin"), ("C compiler command", "/home/conda/feedstock_root/build_artifacts/ghc_1546296476453/_build_env/bin/x86_64-conda_cos6-linux-gnu-cc"), ("C compiler flags", " -fno-stack-protector"), ("C compiler link flags", " "), ("C compiler supports -no-pie", "YES"), ("Haskell CPP command","/home/conda/feedstock_root/build_artifacts/ghc_1546296476453/_build_env/bin/x86_64-conda_cos6-linux-gnu-cc"), ("Haskell CPP flags","-E -undef -traditional"), ("ld command", "/home/conda/feedstock_root/build_artifacts/ghc_1546296476453/_build_env/bin/x86_64-conda_cos6-linux-gnu-ld"), ("ld flags", ""), ("ld supports compact unwind", "YES"), ("ld supports build-id", "YES"), ("ld supports filelist", "NO"), ("ld is GNU ld", "YES"), ("ar command", "/usr/bin/ar"), ("ar flags", "q"), ("ar supports at file", "YES"), ("touch command", "touch"), ("dllwrap command", "/bin/false"), ("windres command", "/bin/false"), ("libtool command", "libtool"), ("perl command", "/opt/conda/bin/perl"), ("cross compiling", "NO"), ("target os", "OSLinux"), ("target arch", "ArchX86_64"), ("target word size", "8"), ("target has GNU nonexec stack", "True"), ("target has .ident directive", "True"), ("target has subsections via symbols", "False"), ("target has RTS linker", "@HaskellHaveRTSLinker@"), ("Unregisterised", "NO"), ("LLVM llc command", "llc"), ("LLVM opt command", "opt") ]

Can you retest this on the latest version if it is still relevant to you? Otherwise I would close this.

luispedro commented 3 years ago

Yes. This is still happening.

conda create -n ghc-test
conda activate ghc-test
conda install -c conda-forge ghc

ghc-pkg recache
ghc Hello.hs -o hello

returns an error:


[1 of 1] Compiling Main             ( Hello.hs, Hello.o )

<no location info>: error:
    Warning: Couldn't figure out C compiler information!
             Make sure you're using GNU gcc, or clang
ghc: could not execute: /home/conda/feedstock_root/build_artifacts/ghc_1631487753784/_build_env/bin/x86_64-conda-linux-gnu-gcc

The file Hello.hs is very simple:

module Main where

main = putStrLn "Hello World"

Again, the /home/luispedro/.anaconda/envs/ghc-test/lib/ghc-8.10.4/settings file references these paths:
