[thread] Simple, all sources, compile fails

[René Rivera]

If I try to do a simple/dumb compile I get errors because some source files assume that they will only be compiled in a particular platform/API. By simple/dumb I mean going to my build system, whatever that might be, and adding all the files under the libs/thread/src/*.cpp & libs/thread/src/*/*.cpp.

[viboes]

Please, could you provide more information so we can help you. I have moved to support request until you give the exact error and context.

[viboes]

Closed by missing details.

[René Rivera]

Sorry for the very delayed response.. Didn't see the trac email about this.

I'm not sure how much more detail I can give other than I was trying to compile for iOS at the time. Simply put one can't compile the libs/thread/src/win32/*.cpp files when compiling for something other than a Windows target as it includes and references Windows specific headers and definitions.

Please note that I said "my build system". I.e. I'm not talking about building with BBv2 and the libs/thread/build/Jamfile.v2.

[viboes]

How do you expect that we solve this issue, if it is one?

[René Rivera]

A common solution is to #ifdef (based on the platform) the source files so that they end up mostly empty.

Please, could you post the error you find and the command line used to get these errors? Otherwise we are unable to help you.

Sure.. Here's a simple example:

Same applies for just about anywhere you try the equivalent simple operation.

HTH.

[viboes]

Depending on the target, the files that must be compiled and the compiler flags are different (see libs/boost/build/Jamfile)

alias thread_sources
    : ## win32 sources ##
      win32/thread.cpp
      win32/tss_dll.cpp
      win32/tss_pe.cpp
    : ## requirements ##
      <threadapi>win32
    ;

alias thread_sources
    : ## pthread sources ##
      pthread/thread.cpp
      pthread/once.cpp
    : ## requirements ##
      <threadapi>pthread
    ;

You will need to add at least the define BOOST_THREAD_POSIX and BOOST_THREAD_USE_LIB.

BTW, why do you want to do this?

[viboes]

Closed, as Boost don't need to support this neither document which sources must be compiled other than the explicit build/Jamfile.

Because of this, it's impossible to compile for Android using BOOST_ALL_NO_LIB. I don't know why boost permanently makes my life a nightmare.

[viboes]

Because you have no name I don't see the need to replay :)
