Fail to build Boost system library

I'm trying to build 'system' library from Boost using command:

bjam --toolset=gcc target-os=qnx --build-dir=c:\boost_1_57_0 --build-type=complete --with-system stage

and keep getting error:

C:\boost_1_57_0>bjam --toolset=gcc target-os=qnx --build-dir=c:\boost_1_57_0 --build-type=complete --with-system stage ...found 1 target... ...updating 1 target... config-cache.write c:\boost_1_57_0\boost\bin.v2\project-cache.jam ...updated 1 target...

The rt lib seems to be missing, where can I obtain such lib to successfully compile 'system' lib?

Solution

  • Solution for my problem:

    • First thing to do is to get MinGW and put it under C:\MinGW.
    • In C:\MinGW\bin there should be gcc
    • Run cmd.
    • In boost (deflaut C:\boost_1_57_0) main folder
    • Set path using command: 'set PATH=c:\mingw\bin;%PATH%'
    • Go to the tools\build directory of your boost folder and run 'bootstrap mingw'
    • To build system lib in root directory type:
    • 'tools\build\b2 toolset=gcc --target-os=qnxnto --build-type=complete stage --with-system'
    • .a files will be in stage\libs folder
