Re: buildkernel fails with a 'invalid conversion specifier' compiler error

Thank you. The workaround helped, but kind of curious now what caused this
failures to start show up. Will try going through commits to see if I can
spot anything.

It's hard to say what is different on your system, but it looks like the
-fformat-extensions flag is somehow not being used for building your
kernel.  If you can't figure out what causes this, you can try to work
around it by setting WITHOUT_FORMAT_EXTENSIONS, or setting WERROR to
empty.

buildkernel fails with a 'invalid conversion specifier' compiler error

[Alex T.]

Hi guys,

I'm on stable/10 branch and have been using it to rebuild world
and kernel. This is the revision I'm currently trying to build but
started seeing the following issue way before it.

URL: svn://svn.freebsd.org/base/stable/10
Revision: 305760

The world builds fine, but building the kernel fails with this error:

/usr/src/sys/cam/cam_xpt.c:1060:27: error:
  invalid conversion specifier 'b'
  [-Werror,-Wformat-invalid-specifier]
  ...printf("%s%d: quirks=0x%b\n", perip...
~^
/usr/src/sys/cam/cam_xpt.c:1061:36: error:
  data argument not used by format
  string [-Werror,-Wformat-extra-args]
  ...periph->unit_number, quirks, bit_st...

This is how my /etc/make.conf looks like:
WITH_PKGNG=yes
SSP_CFLAGS=-fstack-protector-all
WITH_SSP_PORTS=yes
WITHOUT="DOCS"

and I don't have /etc/src.conf. Has anyone seen this issue?

 Any idea what might me misconfigured missing here?

Thank you.
