You need to add -fsanitize=address to compiler flags (both CFLAGS and CXXFLAGS) and linker flags (LDFLAGS). You’ve probably added it to your compiler flags only. Note that using explicit -lasan option has been widely discouraged by ASan developers (e.g. here) as it misses some other important linker flags. The only recommended way to link is … Read more
CMake tries to compile an executable using “standard” (as per what CMake thinks is standard) compiler options and tries to run that executable, so to see if the compiler is working. The executable is simple like int main(int argc, char *argv[]) { return argc – 1; }. You can’t do that when cross-compiling. Because usually … Read more
gcc being a compiler/linker, its -s option is something done while linking. It’s also not configurable – it has a set of information which it removes, no more no less. strip is something which can be run on an object file which is already compiled. It also has a variety of command-line options which you … Read more
As you noticed, these are Makefile {macros or variables}, not compiler options. They implement a set of conventions. (Macros is an old name for them, still used by some. GNU make doc calls them variables.) The only reason that the names matter is the default make rules, visible via make -p, which use some of … Read more
instead of put the first 6 arguments in registers just to move them onto the stack in the function prologue? I was looking at some code that gcc generated and that’s what it always did. Then you forgot to enable optimization. gcc -O0 spills everything to memory so you can modify them with a debugger … Read more
From the GCC manual: Many options have long names starting with -f or with -W—for example, -fforce-mem, -fstrength-reduce, -Wformat and so on. Most of these have both positive and negative forms; the negative form of -ffoo would be -fno-foo. This manual documents only one of these two forms, whichever one is not the default. But … Read more
Because This Question was marked as Duplicate, even if doesn’t have to do with it, because there is about Linker Flag and here is about Compiler Flags, I will post My answer HERE. You will have to go to Settings -> Compiler… and next you’ll have to click on Linker Settings TAB. On the right … Read more
It is normally stored in the comment section strings -a <binary/library> |grep “GCC: (” returns GCC: (GNU) X.X.X strip -R .comment <binary> strings -a <binary/library> |grep “GCC: (” returns no output It is not uncommon to strip the .comment (as well as .note) section out to reduce size via strip –strip-all -R .note -R .comment … Read more
Use -masm=intel and don’t use any .att_syntax directives in your inline asm. This works with GCC and I think ICC, and with any constraints you use. Other methods don’t. (See Can I use Intel syntax of x86 assembly with GCC? for a simple answer saying that; this answer explores exactly what goes wrong, including with … Read more
Debian / Ubuntu The problem is you likely only have the gcc for your current architecture and that’s 64bit. You need the 32bit support files. For that, you need to install them sudo apt install gcc-multilib
