I just finished building it today on my laptop (Thanks Iain!). The GCC-12 branch did not work (I got `configure: error: C preprocessor "/lib/cpp" fails sanity check`) but the development branch works for me (haven’t encountered the potential pitfalls mentioned yet after testing it with some simple programs). Besides, I have also set up everything on both my university server and the compile farm machine, so I can test my work on these two machines as well. What do you mean by a “hello world” warning? You meant to write some simple code like ``` #include <stdio.h> int main () { int a; printf ("hello world\n"); return a; } ``` and to get the warning “warning: use of uninitialized value ‘a’ [CWE-457] [-Wanalyzer-use-of-uninitialized-value]”? Best, Shengyu
