I'd like to embed an RPATH/RUNPATH into all gcc binaries. It isn't enough to
just set LDFLAGS and BOOT_LDFLAGS in the environment; those two variables must
also be passed explicitly as part of the make command:
make LDFLAGS="$LDFLAGS", BOOT_LDFLAGS="$BOOT_LDFLAGS"
So far, so good. However, I'd also trying to use the magic word, '$ORIGIN',
with a literal dollar sign, in the embedded RPATH. LDFLAGS currently looks
like this:
[...]
The problem is that the top-level Makefile specifies enough layers of recursive
calls to make and the shell that I haven't found a way to quote the dollar sign
so that it stays quoted throughout the process. Any hints?
One usual trick to simplify the problem a bit with the shell is:
export 'ORIGIN=$ORIGIN'
You could try:
export 'O=$$O' or something similar to help with make ('O=$O' is not
accepted).
Consider yourself lucky you don't have a qmake layer on top...
It doesn't solve the problem completely, but I thought I'd mention it.
An other trick is to use a wrapper to the linker, that either adds the
$ORIGIN thing, or replaces MYRECOGNIZABLESTRINGWITHOUTDOLLAR with $ORIGIN.
