NAME

       asn1c -- the ASN.1 Compiler

SYNOPSIS

       asn1c [-E [-F] | -P | -R]
       [-Sdir] [-X]
       [-Wdebug-...] [-foption] [-gen-option] [-pdu={all|auto|Type}]
       [-print-option]
       input-filenames...

DESCRIPTION

       asn1c compiles ASN.1 specifications into a set of target language (C/C++) encoders and
       decoders for BER, DER, PER, XER and other encoding rules.

OPTIONS

   Stage Selection Options
       -E     Run the parsing stage only.  Print the reconstructed ASN.1 text.

       -F     Used together with -E, instructs the compiler to stop after the ASN.1 syntax tree
              fixing stage and dump the reconstructed ASN.1 specification to the standard output.

       -P     Dump the compiled output to the standard output instead of creating the target
              language files on disk.

       -R     Restrict the compiler to generate only the ASN.1 tables, omitting the usual support
              code.

       -S directory
              Use the specified directory with ASN.1 skeleton files.

       -X     Generate an XML DTD schema for the specified ASN.1 files.

   Warning Options
       -Werror
              Treat warnings as errors; abort if any warning is produced.

       -Wdebug-lexer
              Enable lexer debugging during the ASN.1 parsing stage.

       -Wdebug-fixer
              Enable ASN.1 syntax tree fixer debugging during the fixing stage.

       -Wdebug-compiler
              Enable debugging during the actual compile time.

   Language Options
       -fbless-SIZE
              Allow SIZE() constraint for INTEGER, ENUMERATED, and other types for which this
              constraint is normally prohibited by the standard.  This is a violation of ASN.1
              standard, and the compiler may fail to produce a meaningful code.

       -fcompound-names
              Using this option prevents name collisions in the target source code by using
              complex names for target language structures.  (Name collisions may occur if the
              ASN.1 module reuses the same identifiers in multiple contexts).

       -findirect-choice
              When generating code for a CHOICE type, compile the CHOICE members as indirect
              pointers instead of declaring them inline.  Consider using this option together
              with -fno-include-deps to prevent circular references.

       -fincludes-quoted
              Refer to header files in #includes using "double" instead of <angle> quotes.

       -fknown-extern-type=name
              Pretend the specified type is known.  The compiler will assume the target language
              source files for the given type have been provided manually.

       -fline-refs
              Include ASN.1 module's line numbers in generated code comments.

       -fno-constraints
              Do not generate ASN.1 subtype constraint checking code.  This may make a shorter
              executable.

       -fno-include-deps
              Do not generate courtesy #include lines for non-critical type dependencies.  Helps
              prevent namespace collisions.

       -funnamed-unions
              Enable unnamed unions in the definitions of target language's structures.

       -fwide-types
              Use the unbounded size data types (INTEGER_t, ENUMERATED_t, REAL_t) by default,
              instead of using the native machine's data types (long, double).

   Codecs Generation Options
       -gen-PER
              Generate the Packed Encoding Rules (PER) support code.

       -pdu={all|auto|Type}
              Create a PDU table for specified types, or discover Protocol Data Units
              automatically.  In case of -pdu=all, all ASN.1 types defined in all modules will
              form a PDU table.  In case of -pdu=auto, all types not referenced by any other type
              will form a PDU table.  If Type is an ASN.1 type identifier, the identifier is
              added to the generated PDU table.  The last form may be specified multiple times to
              add any number of PDUs.

   Output Options
       -print-constraints
              When -EF options are also specified, this option forces the compiler to explain its
              internal understanding of subtype constraints.

       -print-lines
              Generate "-- #line" comments in -E output.
