Building Boost for Android with error “cannot find

问题:

So I am trying to build boost 1.55 for android, but I am getting linking errors for Boost.System and Boost.Atomic, that say "error: cannot find -lrt". Of course, android doesn't have librt because its built into the C runtime. So, I am trying to get boost so it won't link to librt. I tried just deleting every "-lrt" in the source code:

find . -type f | xargs -n1 -P 8 sed -i "s/-lrt//g"

But I still get the same error. How do I make boost not link against librt for android?

回答1:

Indeed all occurrencies of -lrt with sed doesn't seem to have any impact on the problem.
What worked for me (in boost 1.53.0 though) is the following:

• Edit tools/build/v2/tools/gcc.jam

• Comment libs = rt ; in this code section (By the way, it could be that you do not have the -pthread option line):

      case * :
      {
          option = -pthread ;
          libs = rt ;   <--Comment this line
      }

Note: As initial/brute force solution, I would take the failed commands and manually run them removing -lrt from them.
