Bug ID: 52587
Summary: clang-13.0.0: NetBSD<10 does not provide
state_not_recoverable
Product: clang
Version: 13.0
Hardware: All
OS: NetBSD
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: t...@giga.or.at
CC: blitzrak...@gmail.com, dgre...@apple.com,

In NetBSD before release 10 (which is not out yet), the C headers do not
provide ENOTRECOVERABLE, and thus the C++ headers do not provide
std::errc::state_not_recoverable.
This leads to the following compilation problem on NetBSD 9:
[ 65%] Building CXX object
lib/Interpreter/CMakeFiles/obj.clangInterpreter.dir/IncrementalParser.cpp.o
/usr/pkgsrc/lang/clang/work/clang-13.0.0.src/lib/Interpreter/IncrementalParser.cpp:
In lambda function:
/usr/pkgsrc/lang/clang/work/clang-13.0.0.src/lib/Interpreter/IncrementalParser.cpp:56:28:
error: 'state_not_recoverable' is not a member of 'std::errc'
std::errc::state_not_recoverable,
^~~~~~~~~~~~~~~~~~~~~
*** Error code 1
As a workaround I used:
CXXFLAGS=-D_GLIBCXX_HAVE_ENOTRECOVERABLE=1 -DENOTRECOVERABLE=98
and clang-13.0.0 built successfully.
I don't know the proper fix. Can a different std::errc code be used in
IncrementalParser.cpp?
(This problem does not occur any longer on NetBSD-current and will be fixed in
NetBSD 10.)
