Hello, I'm re-sending this e-mail because I think it wasn't sent the first time since I wasn't subscribed to the list. If you got it twice sorry for the inconvenience. I want to modify uclibc-ng and make it do some calls to my library when system calls are invoked. My small library consists of a single prebuilt object file and a header file which I don't know how to statically link in uclibc-ng when I am building it. My makefile-hacking related skills are not exactly great. All I need is to call a couple of my library functions from inside the INLINE_SYSCALL_NCS macro: https://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/tree/libc/sysdeps/linux/ar... Could you give me some hints regarding which Makefiles I need to modify and how? Thanks a lot! Best Regards, Ilias Stamatis
