Compiling with
Shared Libraries | |
The compiler programs (cc,
f77, and pc)
link with Starbase shared libraries by default. Starbase will explicitly
load the appropriate device driver library at run time when you
compile and link with the shared library 〈common〉/lib/libhpgfx.sl,
or use the -lhpgfx
option. This loading occurs at gopen(3G)
time. Assuming you are using ksh(1),
to compile and link a C program for use with the shared library
driver, use the forms below. cc example.c -I〈sb-incl〉 -L〈common〉
-L〈sb-lib〉 -lXwindow \ -lhpgfx -lXhp11 -lX11 -lm -o example
For FORTRAN: fort77 example.f -I〈sb-incl〉 -L〈common〉
-L〈sb-lib〉 -lXwindow \ -lhpgfx -lXhp11 -lX11 -lm -o example
For Pascal: pc example.p -I〈sb-incl〉 -Wl,-L〈common〉
-Wl,-L 〈sb-lib〉 \ -lXwindow -lhpgfx -lXhp11 -lX11 -lm -o example
Compiling with
Archive Libraries | |
You can link the appropriate library, for your specific device
driver, to a program by using any one of the following: The path name 〈sb-lib〉/〈library_name〉.a; An appropriate relative path name; or The -ldd〈device_driver〉
option (for example, -lddhcrx)
with the LDOPTS
environment variable set to -a archive
and exported. Or (preferred because of fewer side-effects), "-Wl,-a,archive".
By default, the linker program ld(1)
looks for a shared library driver first and then the archive library
driver if a shared library was not found. By using "-Wl,-a,archive"
(or exporting the LDOPTS
variable), the -l
option will refer only to archive drivers. As of HP-UX 9.05, archive libraries utilize functionality
that is included in libXext.a.
Because the archive library libhpgfx1.a
references functionality in libXext.a,
it is necessary to explicitly link libXext.a
with your program. Otherwise, the linker will have undefined references. Assuming you are using ksh(1),
to compile and link a C program for use with this driver, use the
forms below. The "-l:libdld.sl"
below specifies the dynamic loader, which is available only in shared-library
form. cc example.c -I〈sb-incl〉
-Wl,-a,archive -L〈common〉 -L〈sb-lib〉 \ -ldd〈device_driver〉
-lXwindow -lhpgfx1 -lhpgfx2 -lXhp11 \ -lXext -lX11 -Wl,-E -Wl,+n -l:libdld.sl -lm -o example
For FORTRAN, use: fort77 example.f -I〈
sb-incl〉 -Wl,-a,archive -L〈common〉 \ -L〈sb-lib〉-ldd〈device_driver〉 -lXwindow
-lhpgfx1 -lhpgfx2 \ -lXhp11 -lXext -lX11 -Wl,-E -Wl,+n -l:libdld.sl -lme \
For Pascal, use: pc example.p -I〈sb-incl〉
-Wl,-a,archive -Wl,-L〈common〉 \ -Wl,-L〈sb-lib〉 -ldd
〈device_driver〉 -lXwindow -lhpgfx1 \ -lhpgfx2 -lXhp11 -lXext -lX11 -Wl,-E -Wl,+n \ -l:libdld.sl -lm -o example
