Description Kevin Buettner 2021-02-24 20:16:24 UTC
Description of problem:

Due to a recent glibc header file change, the file
nat/aarch64-linux-hw-point.c no longer builds on Fedora rawhide.

An enum for PTRACE_SYSEMU is now provided by <sys/ptrace.h>.  In the
past, PTRACE_SYSEMU was defined only in <asm/ptrace.h>.  This is
what it looks like...

In <asm/ptrace.h>:

 #define PTRACE_SYSEMU		  31

In <sys/ptrace.h>:

enum __ptrace_request


When <asm/ptrace.h> and <sys/ptrace.h> are both included in a source
file, we run into the following build problem when the former is
included before the latter:

In file included from nat/aarch64-linux-hw-point.c:26:
/usr/include/sys/ptrace.h:86:3: error: expected identifier before numeric constant
   86 |   PTRACE_SYSEMU = 31,
      |   ^~~~~~~~~~~~~

(There are more errors after this one too.)

The file builds without error when <asm/ptrace.h> is included after
<sys/ptrace.h>.  I found that this is already done in
nat/aarch64-sve-linux-ptrace.h (which is included by

Version-Release number of selected component (if applicable):

How reproducible:


Steps to Reproduce:
1. Attempt to build gdb w/ fedpkg build.
2. Observe build failure for aarch64 architecture.

Actual results:

Build failure.

Expected results:

Successful build.

Additional info:

I have a patch for this problem:


I'll be applying it and (hopefully) committing / pushing it soon.
