# Currently the build system can build a static library or both

|
# static and shared libraries, but not only shared libraries. The
|
|
# name NTL_GMP_LIP is *not* a typo.
|
|
#
|
|
# We have left NTL_ENABLE_AVX_FFT unconditionally disabled: NTL's
|
|
# AVX2 detection can fail even when the CPU supports it (bug
|
|
# 815775), and moreover, can fail due to CXXFLAGS. When that
|
|
# happens, and if we try to use the AVX FFT, the build fails.
|
|
# Finally, doc/config.txt says, "this is experimental at moment, and
|
|
# may lead to worse performance." So we are probably not missing out
|
|
# on much.
