tbb_stddef.h:312:10: error: void tbb::internal::no_assign::operator= is private

[manish_m_]

Hello !!

TBB gives this error while compiling the code. Any suggestions?

tbb_stddef.h:312:10: error: ‘void tbb::internal::no_assign::operator=(const tbb::internal::no_assign&)’ is private
     void operator=( const no_assign& );
          ^
compilation terminated due to -Wfatal-errors.

on gcc version 4.9.2 (Debian 4.9.2-10)

thanks

no_assign is a special type that was created to mark types that should not be assigned. What is the code that leads to the error?

[manish_m_]

I used older version of tbb (v4.2) and it fixed my issue.

However, finding which part of my template-based code led to this error might take too much time. I will report it if i am able to reproduce it on smaller piece of code.

Could you share the compiler output log (not to waste time for a small reproducer)? Perhaps, it can give us some hint what can cause the issue. If the output is huge try to cut only the first error. If you are worried about confidential information, replace your type, class and function names, with something, e.g. "xxxxx".

I think I also have a similar error. I am trying to compile CGAL library with the latest intel tbb stable update and I get this compilation error:
