[Bug ld/16963] New: SEARCH_DIR missing for some targets without sysroot since genscript.sh cleanup (0f70b6b)
https://sourceware.org/bugzilla/show_bug.cgi?id=16963
Bug ID: 16963
Summary: SEARCH_DIR missing for some targets without sysroot
since genscript.sh cleanup (0f70b6b)
Product: binutils
Version: 2.25 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: hp at sourceware dot org
Commit 0f70b6b was not intended to change the tdir for targets without
sysroot. However, it removed the default setting when passed as empty to
genscript.sh. Unfortunately, many genscript.sh invocations in ld/Makefile
accidentally were using a typo'd or plainly wrong tdir-variable (e.g.
$(tdir_cris) instead of $(tdir_crislinux) for the crislinux emulation or
$(tdir_armelf_linux_abi) instead of $(tdir_armelf_linux_eabi), for the
armelf_linux_eabi emulation), causing it to be passed as empty. For
configurations without --with-sysroot, after commit 0f70b6b this means the
corresponding SEARCH_DIR in the linker-script is gone. That this effect was
unintended can be seen in the conversation at
http://sourceware.org/ml/binutils/2013-09/msg9.html. One effect for
targets with dynamic linking and libraries in the intended directory, depending
solely on the now missing SEARCH_DIR (no --rpath-link or other pointers to that
directory) is that linking with libraries depending on DSOs in this directory
causes linker errors.
This is a regression since the binutils 2.24 release.
For example, for a glibc-based toolchain installation with binutils after
commit 0f70b6b, make prog shows this error when requiring dynamic linking
against the rt library in that directory:
/path/to/r101/lib/gcc/crisv32-axis-linux-gnu/4.7.2/../../../../crisv32-axis-linux-gnu/bin/ld:

-rpath-link)

https://sourceware.org/bugzilla/show_bug.cgi?id=16792 --- Comment #3 from Hans-Peter Nilsson hp at sourceware dot org --- (In reply to Cygwin/X maintainer from comment #2) When a sysroot is in use, libraries usually end up in =/lib and =/usr/lib (or =/mingw/lib for *-*-mingw*), but $exec_prefix/$target_alias/lib has still been scanned. Not only is that not happening at the moment, but sysrooting that directory really doesn't make sense. I'm not sure whether you agree or disagree. :) To wit, I'm saying 'don't scan $exec_prefix/$target_alias/lib, scan the target-adjusted equivalent of =/lib; i.e. =/mingw/lib for *-*-mingw*'. ...maybe also =/usr/lib where that isn't a capital offence, e.g. *-*-gnu... IIUC (I'm certainly not sure) sysroot targets don't have (*should* not have) anything in $exec_prefix/$target_alias/lib but everything in =/lib or =/usr/lib so $exec_prefix/$target_alias/lib should not be scanned at all (as such, that is). -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

It's a little more complicated to remove the symbols because _SDA_BASE_ needs to be there if either .sdata or .sbss is present, and similarly for _SDA2_BASE. 2) The linker created .sdata and .sdata2 sections used for R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early. Nowadays we strip unneeded sections from the output, so it isn't necessary to delay creating the sections. 3) The output section for targets of various SDA relocs is now checked as per the ABI(s). We previously allowed .sdata.foo and similar, most likely because at some stage we were checking input sections. Also, the patch fixes a long-standing bug in size_input_sections that affects the values of symbols defined in stripped input sections.
