Bug ID: 33696
Summary: Build failure with C23
Product: binutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: guinevere at redhat dot com
Target Milestone: ---
Attempting to compile gas with C23 will result in the following error:
../../binutils-gdb/gas/read.c: In function ‘find_no_app’:
../../binutils-gdb/gas/read.c:870:20: error: initialization discards ‘const’
qualifier from pointer target type [-Werror=discarded-qualifiers]
870 | char *ends = strstr (s, srch);
| ^~~~~~
That's because in C23, strstr and similar functions will return const char * if
fed a const char *
The issue here is that changing this variable will require changing a function
signature and so on, until needing to change input_line_pointer, which is used
to change the code in the memory region, so it can't just be turned into a
const variable.
I have not tried making the `s` parameter of find_no_app non-const, so that may
be an easier fix, if deemed to be correct.
