[DebianGIS-dev] Bug#568945: [netcdf] dev libraries built without PIC support

[Adrian Benson]

Package: netcdf
Version: 4.1~beta2

Built the latest ver of netcdf from experimental on testing because I
need to build python-netcdf4 which depends on latest netcdf.

Pkgs build fine, however compiling  python-netcdf4 fails due to
non-relocatable symbols in libnetcdf (i.e. the usual pic errors)

Tried correcting the problem by specifying --enable-pic flag in
debian/rules (i.e. DEB_CONFIGURE_EXTRA_FLAGS := ..... --enable-pic)
python-netcdf4 still fails.

I have since built netcdf 4.1 from upstream source (under /usr/local)
using the same configure flags as specified in debian/rules
(+--enable-pic). python-netcdf4 now compiles without error.

Appears to be a packaging error somewhere

P.S.
python-netcdf4 fails when linking to libs fromm libnetcdf-dev:
