Hello,some other informations. The row below is the complete line command that generates the error:"/opt/solarisstudio12.3/bin/CC" -library=stlport4 -xcode=pic32 -g -mt -erroff=%none -xldscope=hidden -m64 -DBOOST_ALL_NO_LIB=1 -DBOOST_TEST_DYN_LINK=1 -I"." -c -o "bin.v2/libs/test/build/sun/debug/address-model-64/threading-multi/visibility-hidden/execution_monitor.o" "libs/test/src/execution_monitor.cpp"If I remove the macro definition -DBOOST_TEST_DYN_LINK=1 the error disappears.Thanks,MirkoOn Wed, Dec 11, 2019 at 2:41 AM mik <mirko.cambi@gmail.com> wrote:Hi,I'm triying to compile the boost 1.70 on Sun solaris using the version 12.3, but I got an annoying error on the test library:"./boost/test/unit_test_log_formatter.hpp", line 39: Error: Identifier expected instead of "__global".For what I can understand it seems that compiler doesn't recognize the keyword __global.Below, there's the command line that I've used:./b2 toolset=sun variant=debug address-model=64 threading=multi link=shared runtime-link=shared --with-testDo you have any suggestions?Thanks,Mirko
