This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
Compiled simple C program and attached with NetBeans using lldb-mi. Can pause and show backtrace but there is no source shown when selecting the stack frame corresponding to my code. Instead an error dialog, similar to Bug 252204, appears when I select a stack frame. The variables view shows the local variables. Note that I have no project. I want to use NetBeans as a plain attachable debugger. Reproduce with the same steps as in Bug 252204 but attach to the following program: #include <stdio.h> #include <unistd.h> int main(int argc, char const *argv[]) { int tick = 0; while (tick++ < 10000) { fprintf(stderr, "Tick %d\n", tick); fflush(stderr); sleep(1); } return 0; } compile and run with: bash$ cc --version Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn) Target: x86_64-apple-darwin14.3.0 Thread model: posix bash$ cc -g -Wall -Werror test.c -o test bash$ ./test The Debugger Log shows ###BEGIN This log is saved to: /var/folders/yt/g4309t6d6m50dn_g25g551rc0000gn/T/gdb-cmds7538633196453937621.log NB build: 201505020001 (gdb) -file-exec-and-symbols "/Users/perm/.gdbinit" (gdb) (gdb) error: 'settings set' takes more arguments error: 'settings set' takes more arguments (gdb) Process 14737 stopped frame #0: 0x00007fff8d05a48a libsystem_kernel.dylib`__semwait_signal + 10 libsystem_kernel.dylib`__semwait_signal: -> 0x7fff8d05a48a <+10>: jae 0x7fff8d05a494 ; <+20> 0x7fff8d05a48c <+12>: movq %rax, %rdi 0x7fff8d05a48f <+15>: jmp 0x7fff8d055c78 ; cerror 0x7fff8d05a494 <+20>: retq (gdb) Process 14737 stopped frame #0: 0x00007fff8d05a48a libsystem_kernel.dylib`__semwait_signal + 10 libsystem_kernel.dylib`__semwait_signal: -> 0x7fff8d05a48a <+10>: jae 0x7fff8d05a494 ; <+20> 0x7fff8d05a48c <+12>: movq %rax, %rdi 0x7fff8d05a48f <+15>: jmp 0x7fff8d055c78 ; cerror 0x7fff8d05a494 <+20>: retq (gdb) (gdb) (gdb) (gdb) (gdb) MI: Error: Command Args.

It looks like there is no symbolic info in the binary being debugged or maybe there is an incompatibility issue. Are you able to debug in the command line mode? BTW, disassembly should work in the next nightly build.
Source debugging works from the command line, both with lldb and with gdb: bash-3.2$ LLDB_DEBUGSERVER_PATH=~/bin/llvm-git/bin/debugserver ~/bin/llvm-git/bin/lldb -- ./test (lldb) target create "./test" Current executable set to './test' (x86_64).

Have you tried the latest build yet?
