Error when compiling on OSX

[postwave]

Sorry to trouble, could you help fix this?

macOS 10.14.5
Apple Clang 10.0.1

Following error messages:

$ dcc test.c
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/runpy.py", line 193, in _run_module_as_main

File "/usr/local/bin/dcc/compile.py", line 102, in compile
UnboundLocalError: local variable 'clang_version_float' referenced before assignment

Thank you.

Hopefully fixed in https://github.com/COMP1511UNSW/dcc/releases/tag/2.3

EDITED

It seems something is incompatible with stdin..

dcc explanation: you are calling a function named fopencookie line 624 of but dcc does not recognize fopencookie as a function.
There are several possible causes:
a) You might have misspelt the function name.
b) You might need to add a #include line at the top of .
c) You might need to add a prototype for fopencookie.

I didn't use any flag and here is the test file

#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[]) {
if (argc!=2) {
printf("Usage: %s number\n", argv[0]);
return 1;
} else {
int n;
int m;
if (sscanf(argv[1],"%d,%d",&n,&m)!=2) {
printf("op\n");
return 1;
} else {
printf("%d %d\n", n, m);
}
}
return 0;
}

[andrew-taylor]

Could you compile with -fsanitize=address e.g.

dcc -fsanitize=address main.c

and let me know how that goes?

Error messages(I missed some brackets in previous comment, error messages should be from <stdin>, edited):

Could report if https://github.com/COMP1511UNSW/dcc/releases/tag/2.4 works please

Similar error to two weeks ago, except it's in different lines of stdin.
Thanks for your patience

Something wrong with format. I didn't realise.
4 ^ are pointing off64_t, off_t, fopencookie, off_t respectively.
