If cloning the bare sources the package needs to be bootstrapped\nin advance with the `autoreconf -vfi` command.\n\nIn addition to the standard build options the following are available:\n\n* `--enable-debug[=no/yes]`:\ncompile for debugging with inlining disabled and warnings\n(disabled by default)\n\n* `--enable-branch-hints`:\nenable branch hints in the reSID engine so the compiler can produce more optimized code\n(enabled by default)\n\n* `--with-simd=\u003cruntime/mmx/sse2/sse4/avx2/avx512f/none\u003e`:\nenable x86 SIMD code for resampling.\nNot required if `-march` or `-mcpu` is already included in the compiler flags\n(i.e. `CXXFLAGS=-march=x86-64-v3`).\n_runtime_ enables runtime dispatch of the resampling function depending on the CPU\nsupported instruction set. Works only when compiling with gcc.\n(none by default)\n\n* `--enable-lto`:\nenable Link Time Optimization if supported by compiler\n(disabled by default)\n\n* `--disable-tests`:\ndisable unit tests and test programs\n(enabled by default)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flibsidplayfp%2Flibresidfp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flibsidplayfp%2Flibresidfp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flibsidplayfp%2Flibresidfp/lists"}
