Open System Services Shell and Utilities Reference Manual (G06.27+, H06.04+)

c89(1) OSS Shell and Utilities Reference Manual

-Wu="symbol_name"

Tells the ld or eld linker to add symbol_name as an undeﬁned symbol. This causes the

linker to search for this symbol in any archive libraries that are speciﬁed after this ﬂag

on the command line or in an obey ﬁle.

The search constraint speciﬁed by the -Wu ﬂag is overridden by use of the

-Winclude_whole ﬂag.

-Wv Echoes the command line to the standard error ﬁle as each component of the compila-

tion system is run.

-Wverbose

Echoes the command line to the standard error ﬁle as each component of the compila-

tion system is run and causes additional output and listings from the SQL compiler to

be sent to the standard output ﬁle. SQL compiler error messages are sent to the stan-

dard error ﬁle.

-Wversion1 | -Wversion2 | -Wversion3

Speciﬁes which C++ dialect to compile.

-Wversion1 speciﬁes the original version, released with D40. This is the default for

systems with a Release Version Update (RVU) prior to G06.00. This value is only

valid for TNS/R-targeted C++ compilations.

-Wversion2 speciﬁes the dialect released with D45. This version supports such

features as the bool type, namespaces, and exceptions.

-Wversion3 speciﬁes the dialect released with G06.20. This version supports an

ANSI/ISO Standard C++ Library corresponding to ISO/IEC IS 14882. This is the

default for TNS/R systems beginning with RVU G06.00 and for TNS/E systems begin-

ning with RVU H06.01.

These three dialects are not compatible.

All modules of a C++ program must be compiled and linked using the same dialect.

-Ww Suppresses the printing of compiler warning messages. This ﬂag overrides any

-Wwarn or -Wnowarn ﬂags.

-W[no]warn[=w [,w ] ... ]

For each w value that appears, this ﬂag enables [disables] the compiler warning mes-

sage speciﬁed by w.

Declaring a w value enables [disables] the speciﬁed message. Specifying -Wwarn

[-Wnowarn] by itself enables [disables] all compiler warning messages.

If -Wwarn=w is speciﬁed, then -Wnowarn must also be speciﬁed or the -Wwarn=w

ﬂag is ignored. If -Wnowarn=w is speciﬁed, then -Wwarn need not be speciﬁed.

If white space is present after the commas, the list of warning message numbers should

be enclosed in quotation marks.

-Wwarn is the default speciﬁcation for this ﬂag. -Ww overrides the -W[no]warn ﬂag.

-Wx Strips part of the symbol table from the output object ﬁle but keeps information neces-

sary for the object ﬁle to be used as input to a linker utility again. This ﬂag is typically

used with -Wr.

Multiple instances of the -D, -I, and -U ﬂags and of the -l operands can be speciﬁed.

The position of -l library operands within a list of ﬂags affects the order in which the libraries are

searched.
