    Isn't it possible to stick to boost::shared_ptr on -4-3, given that's
    what other code does?


It's the collada2gltf code which uses std::shared_ptr at many places so
it would be much work to replace all of them with boost::shared_ptr, but
actually can be done if necessary. I just thought packages are created
with newer compilers, since they generate more better output (in theory).
Other thing is that I need to know whether this is the problem indeed.
So can I know what compilers are used for packages? Are they support
std::shared_ptr?

for LO 4.3 and earlier releases the RHEL5 gcc is used, i don't remember
if it is gcc 4.1 or 4.4; we're only switching to a C++11 compiler for LO
4.4.

actually most users will use the distro provided LO packages anyway and
those don't suffer from our ancient upstream RHEL5 baseline.

anyway, std::shared_ptr and boost::shared_ptr should be mostly the same,
so "find ... | xargs sed -i ..." should be able to fix things up quite
quickly to get a patch for the 4.3 branch.


I tried it an it came out there are other C++11 stuff in the code. I tried
to replace them, but the compiler does not help me with finding C++11 code.
When I compile with --std=c++03 flag, compiler just write out:
error: #error This file requires compiler and library support for the ISO
C++ 2011 standard. This support is currently experimental, and must be
enabled with the -std=c++11 or -std=gnu++11 compiler options.
Is there any option to avoid this general error and force the compiler to
try the older standard.

Thanks,
Tamás
