User Commands (c) c89(1)

-Wallow_cplusplus_comments

Directs the compiler to allow comments that use the C++ comment style in C source

ﬁles.

-Wallow_extern_explicit_instantiation

Allows an extern storage attribute to be applied to an explicit template instantiation.

This ﬂag suppresses the instantiation of the template. If this

ﬂag is omitted, the tem-

plate is instantiated.

The -Wallow_extern_explicit_instantiation

ﬂag is valid only for TNS/R-targeted C++

compilations.

-Wansistreams

Generates a Guardian program that opens text ﬁles as type 180 instead of type 101 if

-Wsystype=guardian is speciﬁed. (By default Guardian programs open text ﬁles as

type 101.) This ﬂag is ignored when -Wsystype=oss is used. OSS programs can open

text ﬁles only as type 180.

-WBdllsonly

Tells the ld or eld linker to limit searches to position-independent code (PIC) ﬁles that

are dynamic-link libraries (DLLs) when resolving the ﬁle names speciﬁed for the -l

operands and -L ﬂags.

If a ﬁle name is qualiﬁed, the linker searches for a DLL with that name.

If a ﬁlename is unqualiﬁed, in each search path, the linker ﬁrst searches for a DLL with

the ﬁle name as speciﬁed in the -l operand or -L ﬂag. If the linker cannot ﬁnd a DLL,

the ﬁle name is unqualiﬁed, and the search path is not in the Guardian ﬁle system (/G),

then the linker preﬁxes lib and sufﬁxes .so to the ﬁle name and searches again. If the

linker still cannot ﬁnd the DLL, it searches the path again with the same preﬁx but with

.srl as the sufﬁx. For more information on search paths, see the Finding Libraries

subsection of the ld(1) or eld(1) reference page under DESCRIPTION.

When a DLL cannot be found, the linker issues an error message unless its

-allow_missing_libs ﬂag is speciﬁed.

The -WBdllsonly, -WBdynamic, and -WBstatic ﬂags are search control toggles.

Multiple ﬂags can be speciﬁed in a single linker invocation; the behavior speciﬁed

remains in effect until another ﬂag in the set is speciﬁed. Thus, you can search for both

DLLs and archive ﬁles for some -l operands and -L ﬂags and search for just archive

ﬁles for others. The default library search control is -WBdynamic.

-WBdynamic

Speciﬁes that the linker utility uses dynamic linking when searching for libraries

speciﬁed in subsequent operands of the form -l library. Dynamic linking is in effect

until a -WBstatic ﬂag is speciﬁed. -WBdynamic is the default setting. Refer to the

Dynamic and Static Linking subsection for details.

-WBstatic

Speciﬁes that the linker utility uses static linking when searching for libraries speciﬁed

in subsequent operands of the form -l library. Static linking is in effect until a

-WBdynamic ﬂag is speciﬁed. -WBdynamic, not -WBstatic, is the default setting.

Refer to the Dynamic and Static Linking subsection for details.
