The library achieves best results for low entropy data as often encountered in space imaging instrument data or numerical model output from weather or climate simulations. %package -n libaec0 Summary: Adaptive Entropy Coding library Group: System/Libraries %description -n libaec0 Libaec provides lossless compression of signed or unsigned integers (samples) of sizes 1 to 32 bits wide. The library achieves best results for low entropy data as often encountered in space imaging instrument data or numerical model output from weather or climate simulations. While floating point representations are not directly supported, they can also be efficiently coded by grouping exponents and mantissa. Libaec implements Golomb Rice coding as defined in the Space Data System Standard documents 121.0-B-2 and 120.0-G-2. %package devel Summary: Development files for libaec, a library for Adaptive Entropy Coding library Group: Development/Libraries/C and C++ Requires: libaec0 = %{version} %description devel Devel files for libaec (Adaptive Entropy Coding library). %package -n libsz2 Summary: Lossless compression library for scientific data Group: System/Libraries %description -n libsz2 Drop-in replacement for the SZIP library (http://www.hdfgroup.org/doc_resource/SZIP). %package -n sz2-devel Summary: Development files for libsz2 Group: Development/Libraries/C and C++ Requires: libaec-devel = %{version} Requires: libsz2 = %{version} Provides: libsz2-devel = %{version} Obsoletes: libsz2-devel < %{version} %description -n sz2-devel Header files for libsz2, a drop-in replacement for the SZIP library (http://www.hdfgroup.org/doc_resource/SZIP). %prep %setup -q -T -a 0 -c cp %{SOURCE1001} . %build %cmake -DCMAKE_C_FLAGS="%{optflags} -std=gnu99" make %{?_smp_mflags} %install %make_install %post -n libaec0 -p /sbin/ldconfig %post -n libsz2 -p /sbin/ldconfig %postun -n libaec0 -p /sbin/ldconfig %postun -n libsz2 -p /sbin/ldconfig %files -n libaec0 %manifest libaec.manifest %doc README.md Copyright.txt doc/patent.txt %{_bindir}/aec %{_libdir}/libaec.so.0* %files devel %{_includedir}/libaec.h %{_libdir}/libaec.so %files -n libsz2 %manifest libaec.manifest %doc README.SZIP %{_libdir}/libsz.so.2* %files -n sz2-devel %{_includedir}/szlib.h %{_libdir}/libsz.so
