libstdc++ in gcc3.
when defined, USE_GCC_SHLIB ensures that the correct rpath is passed
to the linker, and a full dependency on the compiler package is
registered.
packages which define USE_GCC_SHLIB should not include
mk/gcc.buildlink2.mk (or gcc{,3}/buildlink2.mk) as it is handled
automatically.
Some relevant changes:
Fixed miswriting of netCDF header when exiting define
mode. Because the header was always written correctly
later, this was only a problem if there was another
reader of the netCDF file.
Fixed explicit synchronizing between netCDF writer and
readers via the nc_sync(), nf_sync(), and ncsync()
functions.
Fixed a number of bugs related to attempts to support
shrinking the header in netCDF files when attributes
are rewritten or deleted. Also fixed the problem that
nc__endef() did not work as intended in reserving
extra space in the file header, since the extra space
would be compacted again on calling nc_close().
Fixed the "redef bug" that occurred when nc_enddef()
or nf_enddef() is called after nc_redef() or
nf_redef(), the file is growing such that the new
beginning of a record variable is in the next "chunk",
and the size of at least one record variable exceeds
the chunk size (see netcdf.3 man page for a
description of this tuning parameter and how to set
it). This bug resulted in corruption of some values
in other variables than the one being added.
The "__" tuning functions for the Fortran interface,
nf__create, nf__open, and nf__enddef, are now
documented in the Fortran interface man pages.
Changed the extension of C++ files from ".cc" to ".cpp".
Renamed the C++ interface header file "netcdfcpp.h"
instead of "netcdf.hh", changing "netcdf.hh" to
include "netcdfcpp.h" for backward compatibility.
Fixed bug in ncdump using same CDL header name when
called with multiple files.
Added new NULL data type NC_NAT (Not A Type) to
facilitate checking whether a variable object has had
its type defined yet, for example when working with
packed values.
Fixed use of compile-time macro NO_NETCDF_2 so it
really doesn't include old netCDF-2 interfaces, as
intended.
Fixed C++ friend declarations to conform to C++ standard.
out of date - it was based on a.out OBJECT_FMT, and added entries in the
generated PLISTs to reflect the symlinks that ELF packages uses. It also
tried to be clever, and removed and recreated any symbolic links that were
created, which has resulted in some fun, especially with packages which
use dlopen(3) to load modules. Some recent changes to our ld.so to bring
it more into line with other Operating Systems also exposed some cracks.
+ Modify bsd.pkg.mk and its shared object handling, so that PLISTs now contain
the ELF symlinks.
+ Don't mess about with file system entries when handling shared objects in
bsd.pkg.mk, since it's likely that libtool and the BSD *.mk processing will
have got it right, and have a much better idea than we do.
+ Modify PLISTs to contain "ELF symlinks"
+ On a.out platforms, delete any "ELF symlinks" from the generated PLISTs
+ On ELF platforms, no extra processing needs to be done in bsd.pkg.mk
+ Modify print-PLIST target in bsd.pkg.mk to add dummy symlink entries on
a.out platforms
+ Update the documentation in Packages.txt
With many thanks to Thomas Klausner for keeping me honest with this.
Add a new USE_LIBTOOL definition that uses the libtool package instead of
pkglibtool which is now considered outdated.
USE_PKGLIBTOOL is available for backwards compatibility with old packages
but is deprecated for new packages.
