Dmitriy, due to permissions and the various limitations on passing environment variables across processes it is often easier to simply run R and attach the debugger to it:
$ R [...] > Sys.getpid() [1] 89955 > $ sudo lldb Password: (lldb) attach 89955 [...] (lldb) c Process 89955 resuming Also note that you shouldn't change Makeconf by hand, simply supply any CFLAGS you need to configure, e.g.: ../R-devel/configure --enable-R-shlib 'CFLAGS=-Wall -g -O0' 'CXXFLAGS=-Wall -g -O0' Cheers, Simon > On Jul 8, 2020, at 11:08 PM, Dmitriy Selivanov <selivanov.dmit...@gmail.com> > wrote: > > Dear all, > > I'm trying to debug a segfault reported here > https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17850 (thanks Kevin for > the nice article > https://kevinushey.github.io/blog/2015/04/13/debugging-with-lldb/ about > debugging with lldb) > > I need to compile R without optimization (with the O0 flag) instead of > using binaries provided by Simon. > > Here I have difficulties.
