If you are willing to trustĪ long-term archive to a format that has only one implementation, Long-term problems with the hdf5 library. There are many other programs that can handle grib and NetCDF4. Use one of those programs if you want support. Wgrib2 is used in NCEP operations and by many daily processing jobsĪt CPC. Seg-faults are pretty uncommon to wgrib2. The common problemsĪre in related to experimental/alpha features and the following 3 problems. Problem was fixed with an Ubuntu/Debian update to Jasper (fall 2015) which was The jpeg2000 library (Jasper) could seg-fault with larger grids. Jasper library, then your copy of wgrib2 may be vunerable to this If your copy of wgrib2 is using another version of the #PCSWMM VERSIONS UPDATE# Not included with the wgrib2 source code could cause a seg-fault. To g2clib that were not fully incorporated until g2clib v1.4.0. G2clib can be compiled either with a 32 or 64-bit interface. Makefile assumes that a 32-bit interface is used on 32-bit processors and aĦ4-bit interface is used 64-bit processors. NCEP's lead and used a 32-bit interface for 32 and 64 bit machines. Of course, that limits the current g2clib (8/2020) to 2GB files.įinally, the third problem is a compiler bug and only affects #PCSWMM VERSIONS 64 BIT# This problem appears in gcc 2.4.7's handling of unsigned int compiled with older versions of gcc such as 2.4.7.wgrib2 was compiled with OpenMP support. Looping variables when OpenMP is enabled. For example, a few days after the release of wgrib2 v2.0.3, the pnglib There a potential for seg-faults by reading using specially crafted png or jpeg2000Ĭompressed grib files. Was upgraded to fix a seg-fault when reading a specially crafted png file. : PNG support is lacking for bit depths of 1, 2 and 4. : AOCC v3.0 requires OpenJPEG for jpeg-2000 support. The default Jasper library produces empty data. Unfortunately OpenJPEG requires CMake which is unavailable on my work machine. : wgrib2 v3.0.1: the wrong files were written to the web servers This is show that I have some empathy for users with restrictive sys admins.
