[Bug binutils/4970] New: new library handling in binutils causes trouble

Subject: [Bug binutils/4970] New: new library handling in binutils causes trouble with --enable-shared
Date: 28 Aug 2007 23:39:51 -0000

the new build system in binutils sets up custom LD_LIBRARY_PATHs which can cause
conflicts between the build and host.  if you take binutils- and
build/install it with --enable-shared, your host binutils will all be linked
against libbfd-

$ readelf -d `which as` | grep NEEDED.*2.17
 0x0000000000000001 (NEEDED)      Shared library:
 0x0000000000000001 (NEEDED)      Shared library: 

but if you turn and and try to build it again, the LD_LIBRARY_PATH will be set
to your local build directories:

and this makes your installed `as` very angry, especially when cross-compiling
as the local libraries are not targetting the same thing as your host libraries.

i cant think of any use for these LD_LIBRARY_PATHs as each binutils utility
includes a little libtool wrapper script which allows you to execute them in the
build dir and make sure the local shared libs are found and used properly ... so
`make check` would work OK ...
