I have been working with a large application that makes extensive use of templates. When compiled under Unix (with g++), this sees some rather impressive bloat. I have been trying to make a temporary quick-fix by using the -frepo option, which results in dramatically smaller shared objects, but the executables no longer link. I suspect that collect2 is not being called when the -shared flag is used, which would be the cause of this. Here is a simple example I created:
template.h:
test.h:
test.cpp:
main.cpp:
The command line is then as follows:
I have attempted on Solaris 10 with g++ 3.6.4 and Debian stable with g++ 4.1.1-15 with the same result. I have not been able to find any answers with Google on this, so I am rather hoping someone here can enlighten me. Can I use -frepo with shared objects? If so, what am I doing wrong? If not, will I be able to use the -fexternal-templates option to reduce the size?

Hi,
I am looking for references about creating and accessing Shared Objects (.so) through C/C++ on Unix / Linux platforms. Is it possible and where can I find the info.
Thanks

I have two envoirmets(Envoirment A and Envoirment B) running on same server(AIX vesion 5.3).Both have different groups.I am facing a strange problem.Shared objects of one envoirment (Envoirment A)are getting loaded into the second(Envoirment B).So the servers that have dependency on shared objects...

Hi. Does anyone know by how much a text size of an executable(on ibm) would grow if you link one shared object(library)? Is it a constant number or it depends on a .so that is linked? (3 Replies)
hi all !
Do I need all the shared objects to be present while compiling my code which has reference to a only one shared object, which in turn refers to another shared object.
for example I want to compile example.c which refers to sample.so
sample.so has refrence to anothersample.so
do... (2 Replies)
Hi Friends !
I have a library, say libxyz.a.
To view all the object files in the archive, i issued the command :
ar -t libxyz.a
which displayed all the object files it contains.
Now, I would like to know the functions in each object file.
Is there any such command that displays... (3 Replies)
I asked the next question in a former thread :
Can I safely share objects that have virtual functions (i.e. have
virtual function table pointers) between two processes ?
Where will the pointers point to in each process ?
The objects are supposed to reside in shared memory
I received a... (6 Replies)
I'm runtime linking (dlopen and dlsym) to a shared object (library) I've created and after a number of function calls into the library the program core dumps (Illegal operation). This only occurs during runtime linking. If I use the same library and dynamically link during compile time everything... (3 Replies)
