An issue with ./gdb/tui/tui-io.c using macro define(s) that the system curses headers don't provide. 2. An issue with ptrace macro define(s) that are provided in glibc 2.18 or later, but not on CentOS 7, which is glibc 2.17 based. I used Claude Opus 5 to generate a patch and manually inspected it. I am not sure what the GDB policy is for AI assisted patches. I will get the exact compilation failures and the patch to the list on Monday. To be honest, when it comes to the patch, I think I need to be mindful that I am building on Linux (via __linux__), using GCC (via __GNU__) and the glibc version is less than 2.18 using __GLIBC_PREREQ from features.h Regards, Tom
