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)

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

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)

G'day,
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... (0 Replies)

perl::critic::policy::objects::prohibitindirectsyntax
Perl::Critic::Policy::Objects::ProhibitIndirectSyntax(3pUser Contributed Perl DocumentatPerl::Critic::Policy::Objects::ProhibitIndirectSyntax(3pm)
NAME
Perl::Critic::Policy::Objects::ProhibitIndirectSyntax - Prohibit indirect object call syntax.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Indirect object syntax is commonly used in other object-oriented languages for instantiating objects. Perl allows this, but to say that it
supports it may be going too far. Instead of writing
my $foo = new Foo;
it is preferable to write
my $foo = Foo->new;
The problem is that Perl needs to make a number of assumptions at compile time to disambiguate the first form, so it tends to be fragile
and to produce hard-to-track-down bugs.
CONFIGURATION
Indirect object syntax is also hard for Perl::Critic to disambiguate, so this policy only checks certain subroutine calls. The names of the
subroutines can be configured using the "forbid" configuration option:
[Objects::ProhibitIndirectSyntax]
forbid = create destroy
The "new" subroutine is configured by default; any additional "forbid" values are in addition to "new".
CAVEATS
The general situation can not be handled via static analysis.
SEE ALSO
Perl::Critic::Policy::Dynamic::NoIndirect and indirect both do a better job with this, but they require that you compile/execute your code.
