boost support c++11 with Solaris Studio 12.4

[zhifan]

My Environment:

1. boost_version: 1_57
2. solaris stuation version: SolarisStudio12.4-solaris-sparc-bin.tar.bz2 (download yesterday)
3. OS version: bash-3.2$ cat /etc/release

Oracle Solaris 10 8/11 s10s_u10wos_17b SPARC

Copyright (c) 1983, 2011, Oracle and/or its affiliates. All rights reserved.

Assembled 23 August 2011

bash-3.2$ cd tools/build/src/engine/
bash-3.2$ ./build.sh sun
bash-3.2$ tools/build/src/engine/bin.solarissparc/bjam toolset=sun --prefix=/export/home/oracle/zhifan/boost address-model=64 --disable-icu --with-regex --with-log --with-program_options -j64  install

With some code fix in boost, I can run the above command without any "failed". Here is my simple test code:

bash-3.2$ cat boost_log.cc
#include <boost/log/core.hpp>
#include <boost/log/trivial.hpp>
#include <boost/log/expressions.hpp>
#include <vector>
int main() {
std::vector<int> a{1, 2, 3,4,5};
for (auto i : a) {
   BOOST_LOG_TRIVIAL(fatal) << "RedoFile::init ";
}
return 0;
}

bash-3.2$ CC -mt -std=c++11 -m64 -I/export/home/oracle/zhifan/boost/include -DBOOST_LOG_DYN_LINK -L/export/home/oracle/zhifan/boost/lib -lboost_log -DBOOST_LOG_DYN_LINK  boost_log.cc -o boost_log

"boost_log.cc", line 10: Where: Instantiated from non-template code.
2 Error(s) detected.

But if I compile this code with boost library compiled by gcc, it works perfectly.

bash-3.2$ g++ -pthread -std=c++11 -m64 -I/export/home/oracle/zhifan/boost_gcc/include -DBOOST_LOG_DYN_LINK -L/export/home/oracle/zhifan/boost_gcc/lib -lboost_log -DBOOST_LOG_DYN_LINK boost_log.cc -o boost_log
bash-3.2$ export LD_LIBRARY_PATH=/export/home/oracle/zhifan/boost_gcc/lib:$LD_LIBRARY_PATH
bash-3.2$ ./boost_log

This is a compiler bug, the sentry class defined by STL must be convertible to bool (which makes basic_formatting_ostream<>::sentry convertible as well). Please, report it to the compiler vendor.

As for the workaround, I don't have this compiler to test it. I'd appreciate if you could provide a patch. I can suggest two possible avenues of experimenting:

1. Change all conditional expressions involving sentry to double negative forms. E.g. change "if (guard)" to "if (!!guard)".

2. Add operator!() and BOOST_EXPLICIT_OPERATOR_BOOL() to basic_formatting_ostream<>::sentry definition.

Ping? Have you tried the suggested changes?
