Hi All, Thanks for your response. The code snippet is like below (void *)ShMem = shmat(ShId, 0, 0); Error in this line: lvalue required as left operand of assignment. >From GCC 3.4 lvalue casting is removed. Is there any way to solve this error without changing the code? If we can use compiler 4.9.2 without any code modification. Enabling this support by adding any flag, if any? Thanks in advance Regards, Pialy On Thu, Aug 24, 2017 at 5:30 PM, Mason <slash.tmp@xxxxxxx> wrote: > On 24/08/2017 06:27, Pialy Ghosh wrote: > >> Our code written in C++ is compiled with GCC 3.2.1.
