Libsharp is configured, compiled and installed using GNU autotools.

The most complicated step for the user is selecting the appropriate compiler
|
|
flags (and in some cases the compiler).
|
|
|
|
Here are a few (hopefully helpful) examples:
|
|
|
|
GCC, OpenMP, portable executable:
|
|
CFLAGS="-std=c99 -O3 -ffast-math -flto -fopenmp" ./configure
|
|
|
|
GCC, OpenMP, specific optimization for the target CPU:
|
|
CFLAGS="-std=c99 -O3 -march=native -ffast-math -flto -fopenmp" ./configure
|
|
|
|
GCC, no OpenMP, specific optimization for the target CPU:
|
|
CFLAGS="-std=c99 -O3 -march=native -ffast-math -flto" ./configure
|
|
|
|
Clang:
|
|
CC=clang CFLAGS="-std=c99 -O3 -march=native -ffast-math -flto -fopenmp" ./configure
|
|
|
|
MPI support:
|
|
CC=mpicc CFLAGS="-DUSE_MPI -std=c99 -O3 -march=native -ffast-math -flto" ./configure
|
|
|
|
Additional GCC flags for pedantic warning and debugging:
|
|
|
|
-Wall -Wextra -Wshadow -Wmissing-prototypes -Wfatal-errors -pedantic -g
|
|
-fsanitize=address
