Description Sven Rebhan 2009-06-28 06:53:14 UTC
When ld is configured with a sysroot prefix and test is executed:

echo "Testing with absolute linker script (systems libz)..."
echo "GROUP ( /lib/libz.so )" > "${PWD}/libfoo-script.so"
armv4tl-softfloat-linux-gnueabi-gcc test.c -o test libfoo-script.so

the linking process terminates with

Testing with absolute linker script (systems libz)...
/lib/libz.so: file not recognized: File format not recognized
collect2: ld returned 1 exit status

because the Host's library is linked in. For cross-compilation the desired 
behaviour is different. Here, the lib specified in the linker script should be 
searched in the sysroot first! Patch will be attached.

ld should search search in sysroot first

When ld was configured with a sysroot, it should always search for libraries
with absolute filename in this sysroot first.

ld should search search in sysroot first

When ld was configured with a sysroot, it should always search for libraries
with absolute filename in this sysroot first. This patch was tested on
x86_64-pc-linux-gnu without sysroot and armv4tl-softfloat-linux-gnueabi with
sysroot and works ffine on both.
