LabPlot is a program for two- and three-dimensional graphical
presentation of data sets and functions. LabPlot allows you to work
with multiple plots which each can have multiple graphs. The graphs
can be produced from data or from functions.
===> The following configuration options are available for labplot-2.11.80_2:
CANTOR=on: KDE Cantor support
FFTW3=on: Speedier FFTs in the numerical and stats lib (NSL)
FITS=on: Flexible Image Transport System (FITS) data support
HDF5=on: Reading and writing self-describing array data
LIBCERF=on: Complex error functions support
MATLAB=on: MATLAB MAT file support
NETCDF=on: Interfaces for array-oriented data access
ORCUS=on: Spreadsheet processing filters (via liborcus)
ORIGINLAB=on: OriginLab project files support
READSTAT=on: SAS, SPSS, Stata data support
===> Use 'make config' to modify these settings
math/labplot: fix build on armv7
Something (I couldn't quite figure out what) adds -Werror=undef to the
CPPFLAGS, causing a fatal warning somewhere in the Eigen headers:
/usr/local/include/eigen3/Eigen/src/Core/arch/NEON/PacketMath.h:3924:5: error:
'EIGEN_HAS_ARM64_FP16_VECTOR_ARITHMETIC'
is not defined, evaluates to 0 [-Werror,-Wundef]
3924 | #if EIGEN_HAS_ARM64_FP16_VECTOR_ARITHMETIC
| ^
Making this warning not an error fixes the build.
