Hello,
I'm trying to run code that works with ghci 7.8.3 under ghci 7.10.1 but this fails.
Under 7.8.3, when I run from the shell: export LD_LIBRARY_PATH=thepath ghci -lmylib -fno-ghci-sandbox mydriver.hs
I see the usual startup diagnostics along with Loading object (dynamic) mylib ... done final link ... done [1 of 1] Compiling Main Main>
But under 7.10.1, when I do the same, there is no indication that linking happens, and when I try to run the program there are undefined references.
I probably missed the post that explains this behavior. Can somebody provide a pointer to a work-around?
There is two separate issues: 1. ghc-7.10 became less chatty when loads libraries. 'ghci -v2' gets it back with a bit of noise 2. looks more like actual problem. is your mylib fully linked against it's depends? LD_LIBRARY_PATH=/the/path ldd -u /path/to/mylib.so LD_LIBRARY_PATH=/the/path ldd /path/to/mylib.so you can also try to inspect LD_DEBUG=help ghci ... -- Sergei
