i'm about to download one of TS's "official" ARM cross-compile
toolchains for my TS-7260 running 2.4.26-ts9 (soon ts11) and, from
memory, if i pop over here:
ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7260-linux/cross-toolchains/
it would seem i'd be fine with this selection:
crosstool-linux-gcc-4.0.1-glibc-2.3.5.tar.bz2
yes?
but i'm curious about this part of the README in that directory:
"If you wish to utilize the pre-built crosstools, then unpack the
tarballs (as user root) at the root of your file-system. GCC and its
ilk have hard-coded directory paths to search for when looking for the
asm, linker, libraries, etc."
that seems to suggest that i *must* untar the toolchain under the
root directory, and that would be true if the toolchain was
non-relocatable. but i really dislike installing stuff like that
in system directories as root, so i just untarred the tarball under my
regular home directory (where it dumped itself under the ~/opt
directory).
after i do something like that, all i do is append to PATH the
directory of the corresponding toolchain "bin" directory, then write
the canonical "hello, world" program and try to cross-compile it:
$ arm-unknown-linux-gnu-gcc hi.c
$ file a.out
a.out: ELF 32-bit LSB executable, ARM, version 1, dynamically linked
(uses shared libs), for GNU/Linux 2.4.3, not stripped
$
certainly *seems* to work based on that trivial test. so why is the
README implying that install location *must* be under /opt? is that
just a typo? anyone else happily using that toolchain installed
elsewhere? thanks.
