[test] Set fixture for all tests
by Florian Lindner 28 Dec '17

28 Dec '17

Hello, can I set a fixture for the entire test tree, so that it is called before and after each test case? BOOST_FIXTURE_TEST_CASE does that for a test suite, but how can I apply it to all tests e.g. the master test suite? Thanks, Florian

is there a read-write lock for fibers? fibers mutex works also in a "normal" Thread when the scheduler is not installed?

[Units] Name a unit for output
by Santiago Ospina 20 Dec '17

20 Dec '17

Hello boost-users, I would like to know if there is an equivalent for giving a name and a symbol given a unit in boost::units (maybe scaled from another one). I know the example of naming base units, however, it would imply I'd have to create a system and a conversion for every unit I want to implement. I tried to write it directly from the scaled version, like this: template<> struct scale_minute<60, static_rational<1> > { static const long base = 60; typedef Detail::static_rational<1> exponent; typedef double value_type; static value_type value() { return(60); } static std::string name() { return("minute"); } static std::string symbol() { return("m"); } }; however, it is adding my scaled name plus my base name (say the base name is “s” which stands for seconds, then it would print “m” + "s”). Any idea how to overcome with that?

boost.msm and boost.mp11
by Bogdan 19 Dec '17

Now that boost 1.66 includes mp11, is there a plan to upgrade the meta-state machine library (boost.msm) to something less macro dependent? Thank you, Bogdan

Adding C++/CLI code to my project makes app crash on startup
by Sergio Basurco 19 Dec '17

19 Dec '17

Hi, I'm using Boost 1.65.1 with Visual Studio 2015 (v140 compiler). Also, I'm using the following libs dynamically: boost_unit_test_framework boost_log boost_filesystem boost_thread boost_system boost_log_setup boost_chrono boost_date_time boost_regex And I want to add C++/CLI code which is built with /clr. This used to work with v110 and Boost 1.57. Now I'm getting this error just when launching the application. *0xc000007b* All binaries are 32bits. I'm also using the following define: BOOST_ALL_DYN_LINK Any idea on why this may happen? -- Saludos / Best regards, *Sergio Basurco* Coherent Synchro

Issue installing boost 1.65.1 on Centos 7
by Forum (io) 15 Dec '17

15 Dec '17

Dear All, I actually have a problem installing OpenEXR on a Centos 7. My problem is around ilmbase package and pyilmbas *and boost* as boost is required. And I have issue installing boost that I download from here https://gist.github.com/1duo/2d1d851f76f8297be264b52c1f31a2ab Before i decrive my problem let me explain where I looking around boost. When I compil ilambase, I got this error message: /$ ./compile --prefix=/opt/ilmbase2-2-0/ Both display this message/ / /checking for boost::python... no *** Could not run the boost::python test program, checking why... *** The test program could not be compiled. Is boost::python installed? *** Check that the cflags (below) includes the boost::python include directory *** *** Flags used by the test: *** cflags: -g -O2 -I/usr/include/python2.7 -g -O2 -I/usr/include/python2.7 *** ldflags: -L/opt/ilmbase-2-2-0/lib -L/usr/lib64 -L/opt/ilmbase-2-2-0/lib -L/usr/lib64 *** *** You can also run configure with --disable-boostpythontest to skip this test. configure: error: Could not compile boost::python test program. /Someone suggested me to install boost as a share. I downloaded the boost 1.65.1 an untar it into /root/install-package/ Then I tried the following command: cd /root/install-package/boost_1_65_1 sudo ./bootstrap.sh --prefix=/opt/boost_1.65.1 sudo ./b2 address-model=64 variant=release threading=multi link=shared Note that my first attend was with that command cd /root/install-package/boost_1_65_1 sudo ./bootstrap.sh --prefix=/opt/boost_1.65.1 sudo ./b2 And boost was install in /opt/boost_1.65.1 But since I use the command sudo ./b2 address-model=64 variant=release threading=multi link=shared No folder was created in /opt/boost_1.65.1 and at the of the process, this was displayed The following directory should be added to compiler include paths: /root/install-package/boost_1_65_1 The following directory should be added to linker library paths: /root/install-package/boost_1_65_1/stage/lib Then it's look like it boost has been installed in the same folder, where it has been extracted *The my question, what did I do wrong and how can I install boost in /opt/boost_1.65.1 and make it share for ilmbase and OpenEXR? * Feel you free to ask addintionnal question if I missed to provide you Many thank for your help Cheers Pierre* *

Named pipe available to other processes (boost::process)
by Mike Gibson 15 Dec '17

15 Dec '17

It seems that boost::process::basic_pipe::basic_pipe(const std::string& name) on posix creates a fifo using mkfifo, opens it and then unlinks it. I imagine there's a good reason for the unlink step in some situations, but it's causing me issues. I would like to use the fifo later with a non-boost::process started process, so by the time I get around to starting the second process, it can't access the fifo. Is there any workaround for this?

The message itself tells a trivial way to suppress it - so I don't see any problem? Marcel
