 Which is quite strange, as any other arch has compiled it fine, with
 exactly the same line (I have only compared with ia64, but...)

 And using 'nm -D' on hppa openh323, shows that all those symbols are
 present (example):
jose@gimli:~/devel/hppa/usr/lib$ nm -D libopenh323.so.1 | grep OnUserInputInlineRFC

 I'm completey lost with this issue, and having gnomemeeting compiled in
 hppa is quite important for having a new version of all other related
 packages in Sarge, as there are some RC bugs only solved in new

 openh323 (version was compiled with this toolchain:
 Toolchain package versions: libc6-dev_2.3.2.ds1-15
 linux-kernel-headers_2.5.999-test7-bk-16 gcc-3.3_1:3.3.4-7
 g++-3.3_1:3.3.4-7 binutils_2.15-1 libstdc++5_1:3.3.4-7

 gnomemeeting (1.0.2-5, which uses the above openh323 version) was
 compiled with this toolchain:
 Toolchain package versions: libc6-dev_2.3.2.ds1-15
 linux-kernel-headers_2.5.999-test7-bk-16 gcc-3.3_1:3.3.4-9
 g++-3.3_1:3.3.4-7 binutils_2.15-1 libstdc++5_1:3.3.4-7

 There is only a bit diference in gcc.

 Any help here will be appreciated.
