Re: Building and Installing vlagrind 3.15.0 in an embedded Linux cross-compile environment

> I am having some issues with the valgrind 3.15.0 build and install in a cross-compile environment where the resultant code is to run on a router which is embedded Linux.

You must create an absolute path name (starts with '/') that is the same
(as a character string) on the machine which does the cross-compiling
as on the target embedded environment.  Use that as --prefix= for ./configure .

On both machines that path will be a symlink ("ln -s").  On the cross-
compiling machine, set the symlink to be some directory that you can write;
such as:
     mkdir $HOME/cross-valgrind-output
     ln -s $HOME/cross-valgrind-output /common/absolute/pathname
and check via
     ls -l /common/absolute/pathname  # on the cross-compiling machine
           /common/absolute/pathname -> $HOME/cross-valgrind-output

In the image being created for the target embedded environment,
set the symlink to be some directory such as:
     ln -s /opt/valgrind /common/absolute/pathname
and check via
     ls -l /common/absolute/pathname  # in the target embedded environment
           /common/absolute/pathname -> /opt/valgrind
As part of building the target embedded image, then copy the directory tree(s)
from $HOME/cross-valgrind-output/* to the image directory /opt/valgrind/ .


[Notice that this would be simpler if "--prefix=/opt/valgrind".
If you do not have permissions to "mkdir /opt/valgrind" on the cross-compiling
machine, then procure a second-hand x86_64 box, install your favorite
linux distribution on it, and use that box to do the cross-compiling.]
