- -noexport Do not export any symbol
- -norelrelocs Ensure that no relative relocation is generated
- -base Specify base address (Win64 only)
- -pthread Pass -pthread to the linker
- -I <dir> Add a directory where to search for files
- -L <dir> Add a directory where to search for files
- -l <lib> Library file
- -chain {msvc|msvc64|cygwin64|mingw|mingw64|gnat|gnat64|ld}
- Choose which linker to use

- -x64 (Deprecated)
- -defaultlib <obj> External object (no export, no import)
- -save-temps Do not delete intermediate files
- -implib Do not delete the generated import library
- -outdef Produce a def file with exported symbols
- -v Increment verbosity (can be repeated)
- -show-exports Show exported symbols

- -dry Show the linker command line, do not actually run it
- -dump Only dump the content of object files
- -patch Only patch the target image (to be used with -stack)
- -nocygpath Do not use cygpath (default for msvc, mingw)
- -cygpath Use cygpath (default for cygwin)
- -no-merge-manifest Do not merge the manifest (takes precedence over -merge-manifest)
- -merge-manifest Merge manifest to the dll or exe (if generated)
- -real-manifest Use the generated manifest (default behavior)
- -default-manifest Use the default manifest (default.manifest/default_amd64.manifest)
- -export <sym> Explicitly export a symbol
- -noreexport Do not reexport symbols imported from import libraries
- -where Show the FlexDLL directory
- -nounderscore Normal symbols are not prefixed with an underscore

- -vnum Print linker version number and exit
- -help Display this list of options
- --help Display this list of options
-
- Notes:
- * The -I, -l and -L options do not need to be separated from their argument.
- * An option like /linkXXX is an abbrevation for '-link XXX'.
- * An option like -Wl,-XXX is an abbreviation for '-link -XXX'.
- * FlexDLL's object files are searched by default in the same directory as
- flexlink, or in the directory given by the environment variable FLEXDIR
- if it is defined.
- * Extra argument can be passed in the environment variable FLEXLINKFLAGS.
