Hello,
I have a package which links to several libraries, which I have built
with Cabal. I can use it to compile executables:
$ ghc -package vectro --make Vector/Sparse/subvec-example.hs -o sve
Linking sve ...
And the library references in those executables are correct:
$ /lib/ld-2.5.so --list ./sve
linux-gate.so.1 => (0xffffe000)
libgsl.so.0 => /usr/lib/libgsl.so.0 (0xa7dc2000)
libcblas.so.3 => /usr/lib/libcblas.so.3 (0xa7ae3000)
libatlas.so.3 => /usr/lib/libatlas.so.3 (0xa77b6000)
liblapack.so.3 => /usr/lib/atlas/liblapack.so.3 (0xa7166000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xa7081000)
libdl.so.2 => /lib/i686/cmov/libdl.so.2 (0xa707d000)
libX11.so.6 => /usr/lib/libX11.so.6 (0xa6f91000)
libm.so.6 => /lib/i686/cmov/libm.so.6 (0xa6f6b000)
librt.so.1 => /lib/i686/cmov/librt.so.1 (0xa6f61000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xa6f56000)
libc.so.6 => /lib/i686/cmov/libc.so.6 (0xa6e15000)
libblas.so.3 => /usr/lib/atlas/libblas.so.3 (0xa6ab6000)
libg2c.so.0 => /usr/lib/libg2c.so.0 (0xa6a8e000)
/lib/ld-linux.so.2 => /lib/ld-2.5.so (0x75555000)
libXau.so.6 => /usr/lib/libXau.so.6 (0xa6a8a000)
libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xa6a85000)
libpthread.so.0 => /lib/i686/cmov/libpthread.so.0 (0xa6a6e000)
However, when I load the package in ghci, I have some problems:
$ ghci -package vectro

Loading package vectro-0.2 ... ghc-6.6.20070420: can't load .so/.DLL for:
stdc++ (libstdc++.so: cannot open shared object file: No such file or directory)
How do I tell ghci to find stdc++ (etc.) in the same place that ld.so
finds it?
Thanks,
Frederik
