Some patches to Boost 1.60.0 RC1 are required to build my software with GCC 4.4.7 and GCC 4.8.2 on CentOS 6 with the following CXXFLAGS: GCC 4.4.7: -Wall -Wextra -Werror -std=gnu++98 -g -O3 -mtune=native -ffast-math -funroll-loops -DNDEBUG -m64 GCC 4.8.2: -Wall -Wextra -Werror -std=gnu++98 -g -O3 -mtune=native -ffast-math -funroll-loops -DNDEBUG -Wno-unused-local-typedefs -Wstrict-null-sentinel -Woverloaded-virtual -m64 The patches we need are: 1. boost/property_tree/detail/json_parser/standard_callbacks.hpp, adding a "return new_tree();" after the "assert(false);" on line 131. This is https://svn.boost.org/trac/boost/ticket/11501 but my co-worker chose to use the return rather than std::abort() 2. boost/property_tree/detail/json_parser_write.hpp which is previously reported as https://svn.boost.org/trac/boost/ticket/5598 3. boost/lexical_cast.hpp, effectively restoring the file to the version released in 1.59.0. See my previous posting: http://lists.boost.org/boost-users/2015/12/85396.php I'm glad to see some of the issues I reported with Beta 1 have been addressed.

Hi Antony, I hadn't taken note before, but the error is showing up during the compile of MongoDB client code.

See my previous posting: http://lists.boost.org/boost-users/2015/12/85396.php Hi, Sorry for the late response. Could you please send the error message for the lexical_cast issue? About the revert: commit bdc3557 was reverted, because users were complaining, that with value_init move-only types could not be converted using lexical_cast. Here's ticket for that: https://svn.boost.org/trac/boost/ticket/11570 -- Best regards, Antony Polukhin

I forgot to mention that the compilation of the rc with gcc 5.3.0 gives this number of warnings: 1 -Wunused-function 2 -Wstrict-overflow 6 -Wlong-long 8 -Wstrict-aliasing 36 -Wunused-local-typedefs 48 -Wunused-variable On Tue, Dec 15, 2015 at 4:48 PM, Anders Bo Rasmussen wrote:

I can compile it with gcc 5.3.0 on Linux x86_64 in our own toolchain based on Linux From Scratch.

The only minor problem is that when compiling our own projects we now get a warning from 'Target result;' that may be used uninitialized in boost/lexical_cast.hpp:39

As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy.

This helps ensure the candidates build OK before we push them out to SourceForge.

The files (and associated md5s) are: MD5 (boost_1_60_0_rc1.7z) = 7ce7f5a4e396484da8da6b60d4ed7661 MD5 (boost_1_60_0_rc1.tar.bz2) = 65a840e1a0b13a558ff19eeb2c4f0cbe MD5 (boost_1_60_0_rc1.tar.gz) = 28f58b9a33469388302110562bdf6188 MD5 (boost_1_60_0_rc1.zip) = 0cc5b9cf9ccdf26945b225c7338b4288
