USAGE: ruby #{$0} [options]
Flags that are always valid:
--use-system-libraries
--enable-system-libraries
Use system libraries instead of building and using the packaged libraries.
--disable-system-libraries
Use the packaged libraries, and ignore the system libraries. This is the default on most
platforms, and overrides `--use-system-libraries` and the environment variable
`NOKOGIRI_USE_SYSTEM_LIBRARIES`.
--disable-clean
Do not clean out intermediate files after successful build.
--prevent-strip
Take steps to prevent stripping the symbol table and debugging info from the shared
library, potentially overriding RbConfig's CFLAGS/LDFLAGS/DLDFLAGS.
Flags only used when using system libraries:
General:
--with-opt-dir=DIRECTORY
Look for headers and libraries in DIRECTORY.
--with-opt-lib=DIRECTORY
Look for libraries in DIRECTORY.
--with-opt-include=DIRECTORY
Look for headers in DIRECTORY.
Related to zlib:
--with-zlib-dir=DIRECTORY
Look for zlib headers and library in DIRECTORY.
--with-zlib-lib=DIRECTORY
Look for zlib library in DIRECTORY.
--with-zlib-include=DIRECTORY
Look for zlib headers in DIRECTORY.
Related to iconv:
--with-iconv-dir=DIRECTORY
Look for iconv headers and library in DIRECTORY.
--with-iconv-lib=DIRECTORY
Look for iconv library in DIRECTORY.
--with-iconv-include=DIRECTORY
Look for iconv headers in DIRECTORY.
Related to libxml2:
--with-xml2-dir=DIRECTORY
Look for xml2 headers and library in DIRECTORY.
--with-xml2-lib=DIRECTORY
Look for xml2 library in DIRECTORY.
--with-xml2-include=DIRECTORY
Look for xml2 headers in DIRECTORY.
Related to libxslt:
--with-xslt-dir=DIRECTORY
Look for xslt headers and library in DIRECTORY.
--with-xslt-lib=DIRECTORY
Look for xslt library in DIRECTORY.
--with-xslt-include=DIRECTORY
Look for xslt headers in DIRECTORY.
Related to libexslt:
--with-exslt-dir=DIRECTORY
Look for exslt headers and library in DIRECTORY.
--with-exslt-lib=DIRECTORY
Look for exslt library in DIRECTORY.
--with-exslt-include=DIRECTORY
Look for exslt headers in DIRECTORY.
Flags only used when building and using the packaged libraries:
--disable-static
Do not statically link packaged libraries, instead use shared libraries.
--enable-cross-build
Enable cross-build mode. (You probably do not want to set this manually.)
Environment variables used:
NOKOGIRI_USE_SYSTEM_LIBRARIES
Equivalent to `--enable-system-libraries` when set, even if nil or blank.
CC
Use this path to invoke the compiler instead of `RbConfig::CONFIG['CC']`
CPPFLAGS
If this string is accepted by the C preprocessor, add it to the flags passed to the C preprocessor
CFLAGS
If this string is accepted by the compiler, add it to the flags passed to the compiler
LDFLAGS
If this string is accepted by the linker, add it to the flags passed to the linker
LIBS
Add this string to the flags passed to the linker
