Hello,
Since last tests of compiling, I changed my distribution to a Fedora Core 4.
Fedora now includes gcc4 by default... But they also provide compatibility
packages which should allow avoiding compatibility problems.
But, for now, I am not able to compile the c++ examples from the SDK (for
example, OpenOffice.org2.0_SDK/examples/cpp/counter).
Here is the error :
$ g++ -shared -Wl,-rpath,$ORIGIN [...]
-L"/opt/openoffice.org1.9.113/program" [...]
-luno_cppuhelperGCC -luno_cppu -luno_sal -lstlport_gcc
/usr/bin/ld: cannot find -luno_cppuhelperGCC
collect2: ld returned 1 exit status
After some investigation, I noticed that the problem comes from the fact that
the "GCC" from "-luno_cppuhelperGCC" should have been changed to something
like "-luno_cppuhelpergcc3".
I think the problem comes from the file
OpenOffice.org2.0_SDK/settings/settings.mk which should change the GCC in
gcc3.
The following lines are involved :
Lines 247 and following :
ifeq "$(shell echo $(GCC_VERSION) | cut -c 1)" "3"
COMID=gcc3
CPPU_ENV=gcc3
else
COMID=GCC
CPPU_ENV=gcc2
endif
Line 502 : CPPUHELPERLIB=-luno_cppuhelper$(COMID)
Maybe there is something to be done for gcc4.
Yes, looks like the SDK is not yet ready for GCC 4. Note that there are
no successful builds of OOo or SDK on GCC 4 yet, so what you are doing
is "experimental." Anyway, please file an issue that the above will
have to be adapted for GCC 4, so that it is not forgotten. (It seems
that GCC 4 is compatible enough with recent GCC 3 versions, so that we
can continue with a single "gcc3" for both versions.)
After, I tryed to hard code the line :
CPPUHELPERLIB=-luno_cppuhelpergcc3
I compiled, but then I suppose there are linkage problems between the two
versions. Here is the error :
$ make countermain.run
cd /tmp/oooSdk_build//OpenOffice.org2.0_SDK/LINUXexample.out/bin &&
countermain
terminate called after throwing an instance of
'com::sun::star::registry::CannotRegisterImplementationException'
/bin/sh: line 1: 8377 Abandon countermain
This most probably is due to the old libgcc_s.so.1 included in
(Sun-builds) of OOo (are you using a Sun-built OOo?). Try replacing
<ooo>/program/libgcc_s.so.1 (watch out---that might be a symbolic link
to libgcc_s.so.1.1) with the one that comes with your GCC 4 (probably
found under /lib on your system).

So what would be the easyest way to have something working ?
- Install a gcc3 rpm.
- Recompile a gcc3 version for fedora ?
- nything else ?
