Jikes on HP-UX

Jikes has been successfully compiled for HP-UX 10.20 and later, using either gcc or aCC. At the moment, there is no official HP-UX binary; you will need to build your own.

Special information

Sun has not released JDK 1.2 or later for HP-UX 10.20. Jikes should run fine targeting classes.zip in JDK 1.1.8, but you will not be able to use anything in the Java 2 API (such as the Collections framework or javax.swing). One option is using an alternate implementation; if you have a VM that supports Java 2, it should have the classfiles that Jikes needs to link to. The other alternative is to point to a copy of ${JAVA}/jre/lib/rt.jar on another platform. The .jar file is platform-independent, so Jikes will compile the Java 2 API without problems, but your resulting .class files will then require a Java 2 compliant VM to run.

It has been reported that when compiling with gcc3 on HP-UX 11 the ac_cv_header_iconv_h=no paramater to configure is needed.

Source control

  Nothing special : just use WebCVS or install a HP-UX CVS client on your machine (if not already installed). For more information on CVS, see elsewhere in this FAQ.


Compiling with gcc

  Nothing special : this should work like any other *nix clone: ./configure, then make.

Compiling with aCC

  Minor tweaks required : Unfortunately, at this time, aCC will not compile jikes out of the box. However, the changes required are minimal, and this situation may be remedied by 1.14. Untill then you will need patch 1149112 from the queue, since aCC does not like ostream >> unsigned char *.

If you want 64-bit integer math, you will need to configure with the -ext flag. Also, Jikes has a number of non-standard C++ constructs at the moment (again, this will hopefully be fixed by 1.14), which cause aCC to emit a number of warnings. Therefore, the recommended configure call is:

./configure CXX=aCC CXXFLAGS="-g -O -ext +W740 +W741 +W749"

From this point, a simple make should complete the job.

No support for CC

Sorry, but no one has submitted a success story with the old CC compiler. If you can get it to work, please pass that information on to the mailing lists.

Testing the build

Now that you've gone to the trouble of building Jikes on HP-UX, it is a good idea to test it out. You will need to check out the Jacks module, and have Tcl 8.3 installed on your machine. For more details on the testing process, see testing. If you find any platform-specific regressions, report them to the mailing lists (including a patch is even better!).
