How do you figure out which package is missing from your install?
$cat sbstrict.c
int main () {
return 0;
}
$i686-w64-mingw32-gcc -fsanitize=bounds-strict sbstrict.c
/usr/lib/gcc/i686-w64-mingw32/6.4.0/../../../../i686-w64-mingw32/bin/ld:
cannot find -lubsan
collect2: error: ld returned 1 exit status
$gcc -fsanitize=bounds-strict sbstrict.c
/usr/lib/gcc/x86_64-pc-cygwin/6.4.0/../../../../x86_64-pc-cygwin/bin/ld:
cannot find -lubsan
collect2: error: ld returned 1 exit status
I looked at
https://cygwin.com/cgi-bin2/package-grep.cgi?grep=ubsan&arch=x86_64
and both
gcc-debuginfo-6.4.0-5
mingw64-i686-gcc-debuginfo-6.4.0-1
have a ubsan.c, but ld wouldn't be looking for that. Right??
Thanks
Lee
