Bug ID: 64839
Summary: libsanitizer shouldn't require <rpc/xdr.h>
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: harald at gigawatt dot nl

glibc stopped installing rpc headers by default back in 2011: versions 2.14 and
2.15 never install them, versions 2.16 and higher require the configuration
option --enable-obsolete-rpc. Most distros still install the headers for
backwards compatibility, but on systems that use default glibc, building
libsanitizer, and thus GCC, fails with
../../../../gcc/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:134:21:
fatal error: rpc/xdr.h: No such file or directory
Given that libsanitizer doesn't actually use anything from the header other
than as a sanity check, the build shouldn't fail if the header is missing.
GCC is configured with
../gcc/configure --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu
--prefix=$HOME/gcc-run --enable-languages=c,c++
and re-checked today with sources from:
commit 31aebeec4f215f444c96c0dbc333c4eff3f7809a

Version 4.9.2 builds just fine.
