Compile flags

Typically the user will not need to interact with these flags, but we document them here for completeness. Note this list is not exhaustive, others are not exposed but defined in include/glbopts.h. The list below are defined in scs.mk and can be overridden via the command line when compiling by executing, e.g., make DLONG=1, to set the DLONG flag to True.

Name	Description	Permitted values	Default
DLONG	If True use 64 bit integers, else 32 bit	True/False	0
SFLOAT	If True use 32 bit floats, else 64 bit (WARNING: currently broken)	True/False	0
CTRLC	Listen to CTRL-C interruptions	True/False	1
NO_TIMER	Disables code timing	True/False	0
NO_VALIDATE	Disables data validation	True/False	0
NO_PRINTING	Disables all printing in compiled binary	True/False	0
NO_READ_WRITE	Disables the read/write code	True/False	0
GPU_TRANSPOSE_MAT	If on GPU store A transpose in memory	True/False	1
VERBOSITY	Verbosity level (for debugging)	\(\mathbf{N}\)	0
USE_LAPACK	Whether to link in BLAS/LAPACK	True/False	1
USE_OPENMP	Use openmp to parallelize some computation	True/False	0
USE_SPECTRAL_CONES	Enable spectral cone support (log-determinant, nuclear norm, \(\ell_1\) norm, sum-of-largest-eigenvalues). Requires USE_LAPACK=1.	True/False	0
BLAS64	BLAS/LAPACK uses 64-bit integers (ILP64)	True/False	0
NOBLASSUFFIX	The BLAS library has no function name suffix	True/False	0
BLASSUFFIX	The BLAS library uses this suffix	String	‘_’
MATLAB_MEX_FILE	If compiling for use in MATLAB	True/False	0
PYTHON	If compiling for use in python	True/False	0
USING_R	If compiling for use in R	True/False	0
