Ok.. I checked out things a bit more cold-headed tonight, and it seems
that one missing function isn't defined anywhere
(LanguageInterface::LanguageInterface). In contrast, Shared::onHeap()
is defined in Pointer.o
However, both show up in the link errors.
I discovered that the linking command for libhsysinstall is somewhat
wrong. Here it is in all its beauty^Whorror:
gcc31 -shared -Wl,-x -o libhsysinstall.so.0 -Wl,-soname,libhsysinstall.so=
.0 `lorder PackageDescription.cd.So PackageStreamReference.cd.So Feature.S=
o Feature.cd.So PackageFile.So PackageFile.cd.So Database.So Database.cd.So=
Package.So Package.cd.So PackageStreamSubpackage.cd.So PackageStreamFile.S=
o PackageStreamFile.cd.So PackageStreamStructure.cd.So PackageStreamStructu=
re.So PackageCreator.So PackageCreator.cd.So PackageStream.So PackageStream=
.cd.So Callback.So Callback.cd.So FeaturesProvided.So FeaturesProvided.cd.S=
o Exec.cd.So History.cd.So libhsysinstall_init.So /usr/home/anarcat/cvs-wor=
k/libh/lib/sysinstall/../../lib/tcl/TclLanguageInterface.So | tsort -q` -L/=
usr/local/lib -lstdc++ -lgcc -lm
The first thing that is immediatly obvious to me is that Pointer.So is
missing in there. I don't know why/how, but it is, and that is one
major problem. Putting it back in manually immediatly has the effect
of defining Shared::onHeap() properly in libhsysinstall.so.0:
000c77b2 T Shared::onHeap(void const*)
000c76c0 T Shared::isOnHeap(Shared const*)
and in libhsysinstall.a:
Pointer.o:
U _GLOBAL_OFFSET_TABLE_
U _Unwind_Resume
000000f2 T Shared::onHeap(void const*)
00000000 T Shared::isOnHeap(Shared const*)
And hurray! It links!!!
Now as to why, I'll let you in a little secret.
I just redid the experiment *without* modifying the command line, that
is:
1- building the libs straight from make(1)
2- cp(1) the files over
and it just works. Even though Shared::onHeap() and friends is *not*
defined in the library:
U Shared::onHeap(void const*)
U Shared::isOnHeap(Shared const*)
Go figure.
It's probably Alex that had it right all along. My setup was borked.
So many headaches for nothing. :(
I'll just resume my work, thanks for the assistance!
A.
