This patch is needed in situations where build system is running same version of
|
|
jocke@1700
|
4 |
binutils that is intended to be built cross-native ( build != host = target)
|
|
jocke@1700
|
5 |
and has shared libraries enabled. binutils/binutils
|
|
jocke@1700
|
6 |
Makefile has some tools which are built to run on build system. Toplevel makefile
|
|
jocke@1700
|
7 |
for binutils passes HOST_EXPORTS to sub-makefiles which also include RPATH_ENVVARS
|
|
jocke@1700
|
8 |
containing LD_LIBRARY_PATH which is modified so that it also includes host libraries
|
|
jocke@1700
|
9 |
like opcodes and libbfd which are just built for the host system.
|
|
jocke@1700
|
10 |
|
|
jocke@1700
|
11 |
Now the problem is that same LD_LIBRARY_PATH value gets set in environment even
|
|
jocke@1700
|
12 |
for the tools that are being built for build system using CC_FOR_BUILD and the tools
|
|
jocke@1700
|
13 |
like as,ld it invokes from build machine get the LD_LIBRARY_PATH set to search
|
|
jocke@1700
|
14 |
the newly build host libraries like opcodes and bfd and if host is like a big endian
|
|
jocke@1700
|
15 |
system say (mips-linux) the build system linker and assembler do not run because
|
|
jocke@1700
|
16 |
ld.so tries to load these shared libraries instead of the ones from /usr/lib for
|
|
jocke@1700
|
17 |
the build tools.
|
|
jocke@1700
|
18 |
|
|
jocke@1700
|
19 |
This patch fixes the issue by clearing LD_LIBRARY_PATH for BUILD tools
|
|
jocke@1700
|
20 |
|
|
jocke@1700
|
21 |
This patch would be needed on other versions of binutils. I just cared about 2.20
|
|
jocke@1700
|
22 |
May be upstream is also interested in such a patch.
