Error: Can't parse "/usr/lib/ghc/platformConstants"

[myuon]

I got an error message when using fsh: fsh: Can't parse "/usr/lib/ghc/platformConstants"

Running on Ubuntu with ghc-8.0.2 installed by stack,
but I also have ghc-8.0.2 installed by binary package which is not located in my path (this may cause a problem?).

Thanks in advance.

I am not sure what the problem is. I have ghc-7.10.3 which I installed through the ubuntu repositories.

Can you check if you have that file?

Is there any difference from your one?

I think so

Here is what I did.

After applying the patch, I got another error:
fsh: No entry for "readelf command" in "/usr/lib/ghc/settings",
so I added a line ("readelf command", "readelf") to settings file.

Then, fsh said:
fsh: /usr/lib/ghc/package.conf.d/package.cache: GHC.PackageDb.readPackageDb: inappropriate type (Not a valid Unicode code point!)

I guess this is a ghc-8 issue, but just googling, I cannot get enough information about this error.

--
Anyways, I built fsh using stack and it worked. Now I use it.
I am glad to share my information or help to fix this problem, though.
Thanks.

That's so nice and I appreciate your eagerness to help.

Might wanna look into this #4
