Hello all,
As per earlier discussion I'm trying to hack on Phobos to update the random
sampling code.
To do this I've just copied random.d into a new file, randomsample.d, which I'm
modifying and messing around with; I'm trying to build against a local copy of
the GitHub Phobos sources.
When I try and compile,
gdc -nophoboslib -I../phobos/ -o randomsample randomsample.d
I get a huge list of errors, beginning with:
/usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info):
relocation 0 has invalid symbol index 10
/usr/bin/ld: /usr/lib/debug/usr/lib/x86_64-linux-gnu/crt1.o(.debug_info):

relocation 9 has invalid symbol index 2
... and continuing on with a huge number of undefined reference errors.
To check if it was the source of the problem, I tried downloading and building a
local copy of the latest druntime, but the build process fails:
$ make -f posix.mak MODEL=64
[lots of successful stuff, followed by ...]
src/object_.d(237): Error: function object.TypeInfo.toHash of type @trusted
ulong() overrides but is not covariant with object.Object.toHash of type nothrow
@trusted ulong()
src/object_.d(237): Error: function object.TypeInfo.toHash does not override any
function
src/object_.d(347): Error: function object.TypeInfo_Vector.getHash of type

object.TypeInfo.getHash of type nothrow @trusted ulong(const(void*) p)
src/object_.d(347): Error: function object.TypeInfo_Vector.getHash does not
override any function
I can't find any easy or friendly "get started hacking on Phobos" page, so can
anyone advise how to get set up correctly?
Thanks & best wishes,
