The command-line options have the following meanings:
-d filename
--input-def filename
Specifies the name of a .def file to be read in and
processed.
-b filename
--base-file filename
Specifies the name of a base file to be read in and
processed. The contents of this file will be added to the
relocation section in the exports file generated by dlltool.
-e filename
--output-exp filename
Specifies the name of the export file to be created by
dlltool.
-z filename
--output-def filename
Specifies the name of the .def file to be created by dlltool.
-l filename
--output-lib filename
Specifies the name of the library file to be created by
dlltool.
-y filename
--output-delaylib filename
Specifies the name of the delay-import library file to be
created by dlltool.
--export-all-symbols
Treat all global and weak defined symbols found in the input
object files as symbols to be exported. There is a small
list of symbols which are not exported by default; see the
--no-default-excludes option. You may add to the list of
symbols to not export by using the --exclude-symbols option.
--no-export-all-symbols
Only export symbols explicitly listed in an input .def file
or in .drectve sections in the input object files. This is
the default behaviour. The .drectve sections are created by
dllexport attributes in the source code.
--exclude-symbols list
Do not export the symbols in list. This is a list of symbol
names separated by comma or colon characters. The symbol
names should not contain a leading underscore. This is only
meaningful when --export-all-symbols is used.
--no-default-excludes
When --export-all-symbols is used, it will by default avoid
exporting certain special symbols. The current list of
symbols to avoid exporting is DllMain@12, DllEntryPoint@0,
impure_ptr. You may use the --no-default-excludes option to
go ahead and export these special symbols. This is only
meaningful when --export-all-symbols is used.
-S path
--as path
Specifies the path, including the filename, of the assembler
to be used to create the exports file.
-f options
--as-flags options
Specifies any specific command-line options to be passed to
the assembler when building the exports file. This option
will work even if the -S option is not used. This option
only takes one argument, and if it occurs more than once on
the command line, then later occurrences will override
earlier occurrences. So if it is necessary to pass multiple
options to the assembler they should be enclosed in double
quotes.
-D name
--dll-name name
Specifies the name to be stored in the .def file as the name
of the DLL when the -e option is used. If this option is not
present, then the filename given to the -e option will be
used as the name of the DLL.
-m machine
-machine machine
Specifies the type of machine for which the library file
should be built. dlltool has a built in default type,
depending upon how it was created, but this option can be
used to override that. This is normally only useful when
creating DLLs for an ARM processor, when the contents of the
DLL are actually encode using Thumb instructions.
-a
--add-indirect
Specifies that when dlltool is creating the exports file it
should add a section which allows the exported functions to
be referenced without using the import library. Whatever the
hell that means!
-U
--add-underscore
Specifies that when dlltool is creating the exports file it
should prepend an underscore to the names of all exported
symbols.
--no-leading-underscore
--leading-underscore
Specifies whether standard symbol should be forced to be
prefixed, or not.
--add-stdcall-underscore
Specifies that when dlltool is creating the exports file it
should prepend an underscore to the names of exported stdcall
functions. Variable names and non-stdcall function names are
not modified. This option is useful when creating GNU-
compatible import libs for third party DLLs that were built
with MS-Windows tools.
-k
--kill-at
Specifies that @<number> suffixes should be omitted from the
names of stdcall functions that will be imported from the
DLL. This is useful when creating an import library for a
DLL which exports stdcall functions but without the usual
@<number> symbol name suffix.
This does not change the naming of symbols provided by the
import library to programs linked against it, but only the
entries in the import table (ie the .idata section).
-A
--add-stdcall-alias
Specifies that when dlltool is creating the exports file it
should add aliases for stdcall symbols without @ <number> in
addition to the symbols with @ <number>.
-p
--ext-prefix-alias prefix
Causes dlltool to create external aliases for all DLL imports
with the specified prefix. The aliases are created for both
external and import symbols with no leading underscore.
-x
--no-idata4
Specifies that when dlltool is creating the exports and
library files it should omit the ".idata4" section. This is
for compatibility with certain operating systems.
--use-nul-prefixed-import-tables
Specifies that when dlltool is creating the exports and
library files it should prefix the ".idata4" and ".idata5" by
zero an element. This emulates old gnu import library
generation of "dlltool". By default this option is turned
off.
-c
--no-idata5
Specifies that when dlltool is creating the exports and
library files it should omit the ".idata5" section. This is
for compatibility with certain operating systems.
-I filename
--identify filename
Specifies that dlltool should inspect the import library
indicated by filename and report, on "stdout", the name(s) of
the associated DLL(s). This can be performed in addition to
any other operations indicated by the other options and
arguments. dlltool fails if the import library does not
exist or is not actually an import library. See also
--identify-strict.
--identify-strict
Modifies the behavior of the --identify option, such that an
error is reported if filename is associated with more than
one DLL.
-i
--interwork
Specifies that dlltool should mark the objects in the library
file and exports file that it produces as supporting
interworking between ARM and Thumb code.
-n
--nodelete
Makes dlltool preserve the temporary assembler files it used
to create the exports file. If this option is repeated then
dlltool will also preserve the temporary object files it uses
to create the library file.
-t prefix
--temp-prefix prefix
Makes dlltool use prefix when constructing the names of
temporary assembler and object files. By default, the temp
file prefix is generated from the pid.
-v
--verbose
Make dlltool describe what it is doing.
-h
--help
Displays a list of command-line options and then exits.
-V
--version
Displays dlltool's version number and then exits.
@file
Read command-line options from file. The options read are
inserted in place of the original @file option. If file does
not exist, or cannot be read, then the option will be treated
literally, and not removed.
Options in file are separated by whitespace. A whitespace
character may be included in an option by surrounding the
entire option in either single or double quotes. Any
character (including a backslash) may be included by
prefixing the character to be included with a backslash. The
file may itself contain additional @file options; any such
options will be processed recursively.
