 |
|
Hi All,
Has anyone succeeded in implementing a C++ Calc addin for OpenOffice.org version 3?
I have a Calc addin which was first implemented for OpenOffice.org Calc version 1 and has been upgraded once or twice a year to the latest OpenOffice.org version.
Now when I build it for OpenOffice.org Calc version 3, regcomp fails with CannotRegisterImplementationException:
| Code: | regcomp -register -r xxx.rdb -c libxxx.so
libxxx.so
register component 'libxxx.so' in registry 'xxx.rdb' failed!
error (CannotRegisterImplementationException): loading component library failed: libxxx.so |
I guess there is a problem loading the shared library, but I can't see what it is. ldd doesn't report any problems.
So I decided to try instead with a "hello world" C++ Calc addin. The least out of date one that I found is this:
http://wiki.services.openoffice.org/wiki/SimpleCalcAddIn
That's from 2006. I had to make a lot of changes to get it to build:
- My SDK bin directory is /usr/lib64/openoffice.org/basis3.0/sdk/bin. There I find various build tools including idlc, regmerge, and cppumaker, but not regcomp, which is in /usr/lib64/openoffice.org/ure/bin.
- I don't have libcppuhelpergcc3.so, the closest thing is /usr/lib64/openoffice.org/ure/lib/libuno_cppuhelpergcc3.so.3. I still created a symbolic link as described in the document.
- In the past I always used types.db from the program directory, now it seems that this file has been split across some or all of the following:
| Code: | /usr/lib64/openoffice.org/basis3.0/program/legacy_binfilters.rdb
/usr/lib64/openoffice.org/basis3.0/program/offapi.rdb
/usr/lib64/openoffice.org/basis3.0/program/oovbaapi.rdb
/usr/lib64/openoffice.org/basis3.0/program/services.rdb
/usr/lib64/openoffice.org/ure/share/misc/services.rdb
/usr/lib64/openoffice.org/ure/share/misc/types.rdb |
- The link failed with this error:
| Code: | | ld: RNG_impl.o: relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC |
So I recompiled with the given flag and it linked OK.
I guess that all of these changes are necessary because the document is out of date. I am on Fedora 10, the SDK has been packaged as an RPM and I wonder if I have installed it incorrectly. Why have some files been moved from the sdk directory tree to the ure directory tree?
Anyway now the build of this hello world project fails in exactly the same way as my own project:
| Code: | $ regcomp -register -r *.rdb -c *.so
libRNG.so
register component 'libRNG.so' in registry 'RNG.rdb' failed!
error (CannotRegisterImplementationException): loading component library failed: libRNG.so

What am I doing wrong? Has anyone gotten this to work? Is any of this stuff documented anywhere?
Thanks,
Eric |
