-Usage: $0 [OPTION]... [VAR=VALUE]... [TARGET] |
- |
-To assign environment variables (e.g., CC, CFLAGS...), specify them as |
-VAR=VALUE. See below for descriptions of some of the useful variables. |
- |
-Defaults for the options are specified in brackets. |
- |
-Installation directories: |
- --prefix=PREFIX main installation prefix [/usr/local/musl] |
- --exec-prefix=EPREFIX installation prefix for executable files [PREFIX] |
- |
-Fine tuning of the installation directories: |
- --bindir=DIR user executables [EPREFIX/bin] |
- --libdir=DIR library files for the linker [PREFIX/lib] |
- --includedir=DIR include files for the C compiler [PREFIX/include] |
- --syslibdir=DIR location for the dynamic linker [/lib] |
- |
-System types: |
- --target=TARGET configure to run on target TARGET [detected] |
- --host=HOST same as --target |
- |
-Optional features: |
- --enable-optimize=... optimize listed components for speed over size [auto] |
- --enable-debug build with debugging information [disabled] |
- --enable-warnings build with recommended warnings flags [disabled] |
- --enable-visibility use global visibility options to optimize PIC [auto] |
- --enable-wrapper=... build given musl toolchain wrapper [auto] |
- --disable-shared inhibit building shared library [enabled] |
- --disable-static inhibit building static library [enabled] |
- |
-Some influential environment variables: |
- CC C compiler command [detected] |
- CFLAGS C compiler flags [-Os -pipe ...] |
- CROSS_COMPILE prefix for cross compiler and tools [none] |
- LIBCC compiler runtime library [detected] |
- |
-Use these variables to override the choices made by configure. |
