Karl,
It took me a while to remember what this issue was about... but I
managed to get to my old reproducer.
Ok, let me do one step back. The root problem is how do I ensure that
paths passed through ./configure command line are valid when building
source code under 'src' (for example).
Look at the two attached .tar.gz. and un-tar the one called
'autotool-bug-rel.tar.gz'.
In this project I have:
/proj <- Here is where is the configure script
/proj/src <- Here is the source code
/lib <- This is another location of some lib I want to be
able to define through ./configure
Enter the `proj/src` and generate the configure script (./bootstrap.sh
or just use autoreconf).
How is that possible, given the configure script is supposed to be in
'proj', not 'proj/src'?
Launch it with:
./configure --with-mylib=../lib
Similar problem here. If you are where you say, in proj/src, that would
have to be ../../lib.
So let's assume you meant to say that CWD is 'proj'.
Well, I don't think it was ever meant to be possible that sources lie
outside the subtree configure itself is in.
IOW, $(top_srcdir) is, by definition, the location of the ./configure
script, and it actually has to be what it says in the name: the _top_
source directory for stuff built by that configure and its resulting
Makefile.
The source tree should thus be
proj configury here
proj/src sources here
proj/lib other sources here
This may actually be related to my ancient bug entry #20699.
