“You missed this from last year”
“How is that going for Claude's C compiler [0], or Cursor's web browser? [1]”
“The Claude C compiler? 4 months since any changes”
“When was the last time Claude's C Compiler was updated? 4 months ago?”
“what happened to that after the initial press releases”
“Apparently compiling hello world exactly as the README says to is an unfair expectation of the software.”
“The compiler works:”
“You mean the C compiler that literally failed to compile a hello world”
“Someone actually did fuzz the claude c compiler:”
“I am not seeing how this shows that CCC is not impressive”
“I found this was the least impressive bit about it”
“Deliver what exactly? False hope and lies?”
“Considering that it's full of bugs and incomplete implementations and cannot be changed without things breaking down”
“I'd be surprised if the Claude C Compiler didn't have long-term impact”
“Several people have pointed out that the compiler will not emit errors for clearly invalid code.”
“clearly that's not true unless they did some serious hand-waving with kernel config options”
“the compiler itself is working, it's just that the path to the stdlib isn't being passed properly”
“this compiler is far too lenient on what it accepts to the point where I'd hesitate to call it”
“I'm somewhat familiar with gcc and clang's source and it doesn't really particularly look like it to me.”
apparently [hello world does not compile...](https://github.com/anthropics/claudes-c-compiler/issues/1)
“which is a fast path incompatible with the _mm_free implementation”
“claims to have the first line of dmesg”
“such arbitrary and shitty code as this”
