I applied the patches from D24841 and reinstalled libexec/ld-elf.so.1, libexec/ld-elf32.so.1, and usr/include/dlfcn.h. (I had to adapt them minima= lly to apply to releng/12.1.) I also modified the port to use RTLD_DEEPBIND for FreeBSD - the new patches are included. And voila, it is working! Nonetheless, your original remarks show the better solution: libmysqlclient= .so should be compiled with -Bsymbolic (I did not do this in the test above, to= be sure). Is there a way to set this flag directly on an already installed .so file? Thank you, Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
