Conditional src files

Hi,

 

How is it to handle diff files on diff OSs using bjam?

 

What I mean is – say, file File1.cpp exists only Windows and File2.cpp exists only on Linux.

Using a single Jamfile, is there a way to handle it i.e., conditionally add the files to the build, depending on the OS?

 

Thanks a lot in advance,

You can use conditional features:

<target-os>windows:<source>File1.cpp
<target-os>linux:<source>File2.cpp

Thanks Steven!
I'm sorry I didn't give the correct and complete info.

Here's what my Jamfile looks like:


project blah
   : source-location $(OS_SRC) $(OS_LINUX_SRC) $(OS_WIN_SRC)
   ;

lib libblah
:
CommonFile1.cpp
CommonFile2.cpp
WinFile.cpp
LinuxFile.cpp
: <define>$(DEFINES)
: <link>static
;


Now, WinFile.cpp should be included only on Windows and LinuxFile.cpp on Linux. Given this, could you please let me know how I can do it?

Thanks again,

If I remember correctly that isn't allowed.

Hi Steven, Rene, Philip,
Thanks to you all!
Yes, I wanted 'static' and it works like a charm, doing exactly what I want.

I found out why it was not working, based on Steven's first email.
If I have

Option 1:

  F1.cpp
    : <define>$(DEFINES)
        : <link>static
    : <target-os>windows:<source>winfile.cpp  ;

Winfile.cpp is not compiled.

Option 2:
  F1.cpp
    : <define>$(DEFINES)
    : <target-os>windows:<source>winfile.cpp  
        : <link>static ;

I get a syntax error from bjam.

Option 3:
  F1.cpp
    : <define>$(DEFINES)
     <target-os>windows:<source>winfile.cpp  
        : <link>static ;

Works correctly!!

I think using a ':' before <target-os> is the problem. Am I right?
Thanks a lot again to all of you.
Anant

Yes. Please recall that things like 'lib' are just function names.
Then:

   lib libblah
         : F1.cpp
     : <define>$(DEFINES)
      <target-os>windows:<source>winfile.cpp  
  : <link>static ;

is a function call. The ":" character separates parameters to that
function. First parameter is the name of the metatarget to create,
second parameter is the list of sources, third parameter is the
requirements and the fourth parameter is the default build. Requirements
are the build properties that must be always present -- so everything
must be in requirements. E.g. the code above has extra ":", and should
be

   lib libblah
         : F1.cpp
     : <define>$(DEFINES)
       <target-os>windows:<source>winfile.cpp  
    <link>static ;
