bug#42480: cabal-install/GHC fails to find libraries

[John Soo]

Hi Guix,

I have a haskell project until recently compiled with the following:

env -u GHC_PACKAGE_PATH cabal new-build

Now it fails with the following:

ld: cannot find -lm
ld: cannot find -lpthread
ld: cannot find -lz
ld: cannot find -lrt
ld: cannot find -lutil
ld: cannot find -ldl
ld: cannot find -lpthread
ld: cannot find -lm
ld: cannot find -lrt
ld: cannot find -ldl
ld: cannot find -lpthread
ld: cannot find -lpthread
ld: cannot find -lpthread
ld: cannot find -lc

Could a graft be failing to update references to various libraries?

I really don't know what could be going on.

Thanks!

John

Do you have “gcc-toolchain” installed?

Hi Ricardo,

I do have gcc-toolchain installed and I just realized that my project
compiles fine if I do not try to statically link.  I believe this can be
closed as dynamic linking works fine.  My mistake.  I did see the issue
regarding captured inputs to ghc. I am in favor of removing them. I
always must have gcc-toolchain installed when using ghc anyways.

Thanks again,

John

Hi

I think this old bug#42480,

    https://issues.guix.gnu.org/issue/42480

can be closed.

Adding gcc-toolchain fixes the issue.

I am closing.  Let me know if I am missing something.
