Bug ID: 16456
Summary: Wrong directory is searched with non-default emulation
Product: binutils
Version: 2.25 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
On Linux/x86-64, when binutils is configured with --libdir=/usr/lib64,
genscripts.sh treats /usr/lib64 as the default search directory. It
put /usr/lib64 in linker scripts for all emulations, like
---
/* Script for -z combreloc: combine and sort reloc sections */
OUTPUT_FORMAT("elf32-i386", "elf32-i386",
"elf32-i386")
OUTPUT_ARCH(i386)
ENTRY(_start)
SEARCH_DIR("/usr/x86_64-redhat-linux/lib32");
SEARCH_DIR("/usr/i386-redhat-linux/lib32"); SEARCH_DIR("/usr/lib6432");
SEARCH_DIR("/usr/local/lib32"); SEARCH_DIR("/lib32"); SEARCH_DIR("/usr/lib32");
SEARCH_DIR("/usr/i386-redhat-linux/lib"); SEARCH_DIR("/usr/lib64");
SEARCH_DIR("/usr/local/lib"); SEARCH_DIR("/lib"); SEARCH_DIR("/usr/lib");

When I install my own 32bit GCC on Linux/x86-64, I got:
[hjl@gnu-atom-1 tmp]$
/export/build/gnu/gcc-32bit-4.7/release.original/usr/gcc-4.7.4/bin/gcc x.o
/usr/bin/ld: skipping incompatible /usr/lib64/libc.so when searching for -lc
[hjl@gnu-atom-1 tmp]$
