Hi! For the binutils people: debian-hurd is a list of people who are creating an easy-to-install version of the complete GNU system. A lot of us are using cross-compilers right now, and the following is taken from a discussion that we were having.
On the Hurd, libc.so (from glibc-pre2.1) is a linker script that looks like this: ---------------------------------------------------------------------- /* GNU ld script Use the shared library, but some functions are only in the static library, so try that secondarily. */ GROUP ( /lib/libc.so.0.2 /lib/libcrt_nonshared.a ) ---------------------------------------------------------------------- This has caused problems for people who cross-compile, because even though the runtime system uses /lib, we have it mounted as /gnu/lib during compilation. So, /lib/libc.so.0.2 is >>>>> Marcus Brinkmann writes: MB> I am just curious: Why was the path hardcoded at all? The old MB> version of the file seems to work as well. I include it here for MB> your reference. [...] The following would *seem* like the right thing: GROUP ( libc.so.0.2 libcrt_nonshared.a ) but it has a subtle problem. Most of the time it works, but GNU ld searches the current working directory *before* the library path, so if you touch a file called `libc.so.0.2' in the current directory, everything breaks. Try it for yourself. This is why Ulrich changed glibc to use an absolute path. However, I think that an absolute path is just as bad: you have to write a wrapper or modify a script every time you put the libraries into a new directory. The ideal solution, IMO, would be to change GNU ld so that a certain notation can specify a file that is only found in the same directory as the linker script. The current behaviour (search the CWD, then the library search path) might be useful sometimes, but I doubt it is what most people want when they use unqualified filenames in their scripts. I would greatly appreciate anybody's help with this issue, including suggestions for notation, or better yet, patches to GNU ld.
