I've just dug out the patches I used last time I did this... they're not current versions, but should at least give you an idea. According to my notes, the GCC one was applied to all three builds, but the GLIBC one was used only in Chapter 6. Simon.
Force gcc to look for the 64-bit runner in /lib instead of /lib64.

Several changes to force glibc to put 64-bit libraries in /lib instead of /lib64, and 32-bit libraries in /lib32 instead of /lib. The sed expression is kind of ugly, but basically it's looking for something like: /lib64/ld-linux-x86-64.so.2 and extracting the important bits to turn it into: "/lib/ld-linux.so.2 /lib64/ld-linux-x86-64.so.2 /libx32/ld-linux-x32.so.2" The change makes it instead produce: "/lib32/ld-linux.so.2 /lib/ld-linux-x86-64.so.2 /libx32/ld-linux-x32.so.2" diff --git a/sysdeps/unix/sysv/linux/x86_64/ldconfig.h b/sysdeps/unix/sysv/linux/x86_64/ldconfig.h index 6f5b828..e8b2b6b 100644 --- a/sysdeps/unix/sysv/linux/x86_64/ldconfig.h +++ b/sysdeps/unix/sysv/linux/x86_64/ldconfig.h @@ -18,9 +18,9 @@ #include <sysdeps/generic/ldconfig.h> #define SYSDEP_KNOWN_INTERPRETER_NAMES \ - { "/lib/ld-linux.so.2", FLAG_ELF_LIBC6 }, \ + { "/lib32/ld-linux.so.2", FLAG_ELF_LIBC6 }, \ { "/libx32/ld-linux-x32.so.2", FLAG_ELF_LIBC6 }, \ - { "/lib64/ld-linux-x86-64.so.2", FLAG_ELF_LIBC6 }, + { "/lib/ld-linux-x86-64.so.2", FLAG_ELF_LIBC6 }, #define SYSDEP_KNOWN_LIBRARY_NAMES \ { "libc.so.6", FLAG_ELF_LIBC6 }, \ { "libm.so.6", FLAG_ELF_LIBC6 }, diff --git a/sysdeps/unix/sysv/linux/x86_64/ldd-rewrite.sed b/sysdeps/unix/sysv/linux/x86_64/ldd-rewrite.sed index 44d76e8..58d977c 100644 --- a/sysdeps/unix/sysv/linux/x86_64/ldd-rewrite.sed +++ b/sysdeps/unix/sysv/linux/x86_64/ldd-rewrite.sed @@ -1,3 +1,3 @@ /LD_TRACE_LOADED_OBJECTS=1/a\ add_env="$add_env LD_LIBRARY_VERSION=\\$verify_out" -s_^\(RTLDLIST=\)\(.*lib\)\(\|64\|x32\)\(/[^/]*\)\(-x86-64\|-x32\)\(\.so\.[0-9.]*\)[ ]*$_\1"\2\4\6 \264\4-x86-64\6 \2x32\4-x32\6"_ +s_^\(RTLDLIST=\)\(.*lib\)\(\|64\|x32\)\(/[^/]*\)\(-x86-64\|-x32\)\(\.so\.[0-9.]*\)[ ]*$_\1"\232\4\6 \2\4-x86-64\6 \2x32\4-x32\6"_
