(For Itanium(R)-based Systems)
The following internationalization variables affect the execution of
ld:
LANG
Determines the locale category for native language, local customs and coded character set in the
absence of LC_ALL and other LC_* environment variables. If
LANG is not specified or is set to
the empty string, a default of
C (see lang(5)) is used instead of
LANG.
LC_ALL
Determines the values for all locale categories and has precedence over
LANG and other LC_*
environment variables.
LC_MESSAGES
Determines the locale that should be used to affect the format and contents of diagnostic messages
written to standard error.
LC_NUMERIC
Determines the locale category for numeric formatting.
LC_CTYPE
Determines the locale category for character handling functions.
NLSPATH
Determines the location of message catalogs for the processing of
LC_MESSAGES.
If any internationalization variable contains an invalid setting,
ld behaves as if all internationalization
variables are set to
C. See environ (5).
In addition, the following environment variable affects
ld:
TMPDIR
Specifies a directory for temporary files (see tmpnam(3S)).
BROWSER
Specifies the pathname of the browser to display the HP-UX Linker and Libraries Online User’s
Guide when you use the +help option.
DIAGNOSTICS
ld returns zero when the link is successful. A non-zero return code indicates that an error occurred.
EXAMPLES
Link part of a C program for later processing by
ld. (Note the .o suffix for the output object file; this is
an HP-UX convention for indicating a linkable object file):
ld -r file1.o file2.o -o prog.o
Link a shared bound program in standard mode. Note that crt0.o is not specified because for shared
links, it is no longer necessary.
ld himom.o -lc
Link a simple Fortran program to use with a symbolic debugger (see wdb(1)). Because the -o option is
not specified on the command line, the output file name is a.out.
ld ftn.o -lcl -lisamstub \
-lc /opt/langtools/lib/pa20_64/end.o
Create a shared library:
ld -b -o libfunc.so func1.o func2.o func3.o
Create a shared library with an internal name, and this shared library allows dynamic library searching:
ld -b -o libfoo1.so.1 foo1.o foo2.o +h libfoo1.so.1
ln -s libfoo1.so.1 libfoo1.so
cc -g mytest.c -L. -lfoo1
chatr a.out
...
shared library list:"
libfoo1.so"
If you do not use
+h, the shared library does not have an internal name. The linker does not check
whether .so is a symbolic link. It records the library name that it looks at, if it does not have the inter-
nal name.
