Hi,

/usr/include/aarch64-linux-gnu/unixODBC/unixodbc_conf.h contains:
#define LT_DLSEARCH_PATH "/lib:/usr/lib:/usr/local/lib/aarch64-linux-gnu:/lib/aarch64-linux-gnu:/usr/lib/aarch64-linux-gnu:/usr/lib/aarch64-linux-gnu/libfakeroot:/usr/local/lib"

Apparently it picks up the LD_LIBRARY_PATH modification done by
fakeroot. But this library path is wrong at runtime.

Please fix the build to not include the libfakeroot directory.

Best,
Chris

Hi Chris,

I think it should be enough to rebuild this package with a recent dpkg
that no longer uses fakeroot by default with Rules-Requires-Root: (but I
did not test this).

This was discussed in #debian-devel today:

13:38 <hmc> libtool's autoconf picks up LD_LIBRARY_PATH via LT_SYS_DLSEARCH_PATH
13:40 <hmc> in this case, unixodbc_conf.h is a private header.
13:42 <hmc> (it indicates how unixodbc was built)

And I found a number of packages with the same diff:

gerris
libapr1-dev (with other changes)
libdiagnostics-dev
libotf2-trace-dev (with other changes)
librep-dev
libtool-bin
pinball-dev
proftpd-core (with other changes)
r-base-core (with other changes and log size limit)

So maybe this should be reassigned to autoconf?

Cheers Jochen

Maybe, maybe not. I'm guessing the packages themselves control if
they let the build-time library path end up in their header or
binary files.

If so, I don't think autoconf can do much about it.

I have updated the buildd chroot generation script to no longer install
fakeroot by default and asked for binNMUs for all bug pinball-dev (is R³
binary-targets) and verified that this reproduces now. I still think it
would be better to not expose the build time LD_LIBRARY_PATH in the
installed unixodbc_conf.h but that is probably minor, so closing this.

Cheers Jochen

Thanks for this work.

As indicated in an early response, unixodbc_conf.h is a private header
and indicates how unixodbc was built.

I'll probably patch out the LD_LIBRARY_PATH line at the next upload. In
fact, it might be easier to avoid shipping the header.
