HP C/aC++ for PA-RISC Software manual Linking Your HP aC++ Libraries with Other Languages

NOTE: If you distribute either executable files or shared libraries as part of your product, do not ship these HP aC++ runtime libraries with your product in such a way that it results in overwriting a newer library version with an older, incompatible version. Ensure that an older library version is not installed over a newer one.

Linking Your HP aC++ Libraries with Other Languages

The C++ language requires that non-local static objects be initialized before any function or object is used. HP aC++ automatically initializes non-local static objects in all object files, including shared libraries, before the first statement in main() executes. No special files or link options are needed.

If the library is being dynamically loaded from pure C or Java as a plugin, the library should be linked with the HP aC++ runtime libraries in the following order:

-AA: -lstd_v2 -lCsup -lunwind -lm

If tools.h++ is used, then add -lrwtool(or -lrwtool_v2) to the left.

In addition, your customers must review Chapter 10: “Mixing C++ with Other Languages” (page 188) for information on linking HP aC++ modules with HP C, and HP FORTRAN 90.

Installing your Application

HP aC++ releases are usually forward compatible, but HP cannot guarantee that this will be true for all releases. If you have questions about the compatibility of HP aC++ releases, you should contact your HP support representative.

Normally your customer will already have the correct runtime installed. If your product requires a newer version, it is recommended that the customer install the latest runtime patch.

Your application’s installation procedure should install the appropriate HP aC++ components in the standard directories on your customer’s systems. This will ensure that the aCC command can find them.

NOTE: If your customer already has HP aC++ installed and their version is newer than yours, do not overwrite any of the existing HP aC++ components. Do not install your product on a system that has a newer version of HP aC++ if that newer version is incompatible with your version.

Ensure that your customer does not install a version of HP aC++ after installing your product; if that version of HP aC++ is incompatible with your version.

HP aC++ Files You May Distribute

You can package and redistribute the following HP aC++ components to your customers. The following HP aC++ runtime libraries are provided as a patch to the HP-UX core system:

•/usr/lib/hpux##/libCsup.so

•/usr/lib/hpux##/libCsup11.so

•/usr/lib/hpux##/libstd.so and libstd_v2.so

•/usr/lib/hpux##/librwtool.so and librwtool_v2.so

•/usr/lib/hpux##/libstream.so

where ## is 32 or 64, which are provided as part of the HP-UX core system.
