Bug ID: 271044
Summary: textproc/source-highlight: fix build with clang 16
Product: Ports & Packages
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: Individual Port(s)

Flags: maintainer-feedback?(tcberner@freebsd.org)
Since clang 16 (and gcc 11) the default C++ standard is now gnu++17.
Because textproc/source-highlight's Makefile does not explicitly set its C++
standard, this leads to several errors:
In file included from fileutil.cc:28:
./fileutil.h:30:41: error: ISO C++17 does not allow dynamic exception
specifications [-Wdynamic-exception-spec]
string readFile(const string &fileName) throw (IOException);
^~~~~~~~~~~~~~~~~~~
./fileutil.h:30:41: note: use 'noexcept(false)' instead
string readFile(const string &fileName) throw (IOException);
^~~~~~~~~~~~~~~~~~~
noexcept(false)
fileutil.cc:51:41: error: ISO C++17 does not allow dynamic exception
specifications [-Wdynamic-exception-spec]
string readFile(const string &fileName) throw (IOException) {
^~~~~~~~~~~~~~~~~~~
fileutil.cc:51:41: note: use 'noexcept(false)' instead
string readFile(const string &fileName) throw (IOException) {
^~~~~~~~~~~~~~~~~~~
noexcept(false)
In http://git.savannah.gnu.org/cgit/src-highlite.git/commit/?id=416b397
indicates that after 3.1.9 C++11 will be required and supported, so add
USE_CXXSTD=gnu++11 to avoid the errors for now.
