It has probably been optimised out of your compiled code as you only use feature_mask[i] within the loop. Did you specify an optimization level when you called your compiler? If you were using gcc, then just omit any -O options and try again.
The exact line to write in your ~/.lldbinit file is settings set target.x86-disassembly-flavor intel In the future, you will also be able to tweak how immediate values are displayed with the new settings: target.use-hex-immediates and target.hex-immediates-style.
You can use command thread apply all bt or thread apply all bt full to get backtraces of all threads. Might be useful. By the way if you get rid of you handler will your OS create a core file?
You should be able to construct a new std::string within the GDB. You want to allocate space on the heap to hold the std::string object, invoke the default constructor, and assign your string value. Here is an example: (gdb) call malloc(sizeof(std::string)) $1 = (void *) 0x91a6a0 (gdb) call ((std::string*)0x91a6a0)->basic_string() (gdb) call ((std::string*)0x91a6a0)->assign(“Hello, World”) $2 = … Read more
I use this one personally: gdb’s cheat sheet or that link is not broken yet .. . I ‘ve printed it at work.
I solved this issue with “Embedded Binaries” in the General project settings.
(gdb) p &a if you need the address of variable a. A variable might be cached in a register though, in which case GDB would tell you address requested for identifier “a” which is in register $xxx. Sidenote: do not use gets, see here.
I know there is already a fine answer for this, but I prefer not using an additional file. Here is another answer: gdb attach $(pidof process_name) -ex cont
gdb is not a compiler, it will not do the (not-so-)nice user-defined type conversions for you. If you wish to call a function that wants a string, you need to give it a string, not a const char*. Unfortunately, gdb cannot construct an std::string for you on the command line, again because it is not … Read more
print *variable If you do that it will display the value of that variable in GDB. You also have an option to display the struct with indentation and new lines: $1 = { next = 0x0, flags = { sweet = 1, sour = 1 }, meat = 0x54 “Pork” } For that you need … Read more
