I am attempting to generate a C file from another C file and then create a library from the generated sources (~2000 files). I tried this and it causes bjam to use massive amounts of memory and time:

 

type.register GEN_C : : C ;

 

generators.register-standard gen.generate : C : GEN_C(GEN_%) ;

 

rule generate ( targets * : sources * : properties * )

{

}

 

actions generate

{

    “gen_c.py"  -f $(>) -o $(<)

}

 

rule gen_lib ( main-target-name : sources + : requirements *  : default-build * : usage-requirements * )

{

    for local file in $(sources)

    {

        gen-c $(file:B) : $(file) ;

        files += $( file:B) ;

    }

    lib $(main-target-name) : $(files) : $(requirements) <implicit-dependency>$(files:B) : $(default-build) : $(usage-requirements) ;

}

 

gen_lib lib : [ glob *.c ] ;

 

There is obviously a better solution.  Can someone suggest what to do here?  I looked at the custom generator example in the manual and I am not sure it will do what I want.  Can someone confirm that custom generators are the right choice here? Will this solve the memory and time problem?

 

Thanks,

 

Chris
