debugging - g++ "value temporarily unavailable, due to optimizations" -


i'm getting "value temporarily unavailable, due optimizations" problems, am compiling debug enabled, far know.

i.e. i'm using -g -o0 -fno-inline flags, i'm not sure why still happening. flag missed?

compiler g++-mp-4.6 (gcc) 4.6.3, os osx 10.6 darwin palace-of-the-nine-moons.local 10.8.0 darwin kernel version 10.8.0: tue jun 7 16:33:36 pdt 2011; root:xnu-1504.15.3~1/release_i386 i386

full compile options g++-mp-4.6 -wall -werror -wno-unused -g -o0 -fno-inline -i/usr/local/include -i../allig -std=c++0x -c src/toolbox.cpp -o o/toolbox.o every file.

code snippets:

void icon::resize (unsigned char w, unsigned char h) {     unsigned short ow,oh;     ow=al_get_bitmap_width(icon);

up

void icon::create_icon (unsigned char _icon_size) {     resize(_icon_size,_icon_size); }

up

int icontainer::add_icon (icon *tt) {     int ret=icons.size();     tt->tool=tool_tile;     tt->create_icon(icon_size);

finally here icon size available.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
