I tried several gdb/lldb options to debug libtcc generated code. But gdb/lldb complained that they could not load symbols or that module does not exist. There was also another problem. The code itself was in memory (string) and gdb/lldb do not have functions to acces it. So I came up with a new api for debugging libtcc code. First you enable debugging with: tcc_set_options(s, "-g") Then compile the code with: tcc_compile_string_file(s, program, "<file>.c") Then call tcc_relocate(). And finaly write the object file to disk: elf_output_obj(s, "<file>.o") Now you can start the debugger and put an breakpoint after the elf_output_obj() code. Then use gdb command add-symbol-file <file>.o and from there on you can set breakpoints in the libtcc generated code. You can also step/print variables/... I could not find a simular function in lldb yet. When debugging is done you remove the tcc_set_options(s, "-g"). All other code can remain because tcc_compile_string_file and elf_output_obj do not output any file any more is debug is not set. See also tests/libtcc_debug.c |
