Using udk and freestore (fs)

[Alon Blayer-Gat]

From other posts, your application is a bunch of .a archives pulled in
by one .cc main program.
The best approach is to compile all the source files that go into
the .a's with -Tauto (the default), and not either -Tlocal or -Tused.
Then do a CC -Tprelink_objects on all the .o's that are going into a
particular archive, before doing the "ar" command to create the archive.
Then compile the main program with the default -Tauto as well.
Then link.
If you take this approach, does it link correctly, with and without
using "fs"?> Jonathan SchillingHi,I recompiled all my libraries as you

suggested. and ran CC -Tprelink_objects *.o before 'ar'.When I arrived the
linkage phase I had to seperate compilation from linkage in order to
manipulate the .ti file.This is due to the following compiler
flag -DTEMPLATE_DECL=template<> . I had to change it
to -DTEMPLATE_DECL=template\<\> in the .ti file.Otherwise the shell/compiler
are confused.After that I managed to linke and recived the following

When I arrived the
linkage phase I had to seperate compilation from linkage in order to
manipulate the .ti file.This is due to the following compiler
flag -DTEMPLATE_DECL=template<> . I had to change it
to -DTEMPLATE_DECL=template\<\> in the .ti file.Otherwise the shell/compiler
are confused.

This is a known problem that was corrected in I believe UnixWare 7.1.2
(Open UNIX 8.0.0). The escapes are now added by the compiler when it
generates the .ti file, so no need for you to do it:

$ CC -DTEMPLATE_DECL="template<>" test5.cpp test5b.cpp
test5.cpp:
test5b.cpp:
prelink: INFO: C++ prelinker: executing: CC -c
-DTEMPLATE_DECL=template\<\> test5.cpp

I'm using UW 7.1.1 with UDK 8
I complile with -DTEMPLATE_DECL=template\<\>
But still it is inserted to the .ti file as -DTEMPLATE_DECL=template<>
Thus prelinking does not pass.
double quots, -DFLAGS=\"hello\" for example are inserted with the
backslash, this is OK.

After that I managed to linke and recived the following

Your posting lost all its line breaks, which makes it hard to get
much from.

But just to verify, this is the approach you should have taken:

$ CC -c a.cpp b.cpp c.cpp
$ CC -Tprelink_objects a.o b.o c.o
$ ar rv libone.a a.o b.o c.o

$ CC -c d.cpp e.cpp f.cpp
$ CC -Tprelink_objects d.o e.o f.o
$ ar rv libtwo.a d.o e.o f.o

$ CC -c main.cpp

$ CC -L. main.o -lone -ltwo

If you follow this scheme and still get unresolved references or
missing template instantiations, analyze what's missing. Is it
a use from one .o to another .o within a .a, or is it a use
across a .a, or what?

Hi,

I have rechecked, I was doing it like you suggested.
The unresolved references or missing template instantiations are
always from other libraries.
That is it's of .o files which reside in different libraries.

Given the structure of the symbols and instantiations involved,
see if you can reproduce the problem using a relatively small amount
of code. (I know, often easier said than done.)

Also, look at your template definition scheme. Anywhere that
an instantiation needs to be done, the relevant template definition
must be available. So for example if archive A needs an instantiation
of template T, but the definition of T only exists within archive B,
you might have a problem.
