  2. +

    Viewing the software (make HTML)

    +Commands + +
    +cd loncom/build
    +rm -Rf HTML (or alternatively, "make clean")
    +make HTML
    +cd HTML
    +(look at the index.html file with a web browser such as Netscape)
    +
    +
    +General description of what happens +

    +This is the actual make target code. + +

    +
    +HTML:
    +        install -d HTML
    +        cp ../../doc/loncapafiles/*.gif HTML
    +        perl parse.pl ../../doc/loncapafiles/loncapafiles.html HTML > HTML/index.html
    +
    +
    + +What basically happens is that specially marked-up data in the LON-CAPA +cvs repository file doc/loncapafiles.html is parsed into a more +viewable format by loncom/build/parse.pl. The resulting +file gives a very well organized view of all the files, directories, +links, ownerships, permissions, and brief documentation of what each +file does. +

    +
  3. +

    Compiling the software (make build)

    +Commands + +
    +cd loncom/build
    +make build
    +
    +
    +General description of what happens +

    +This is the actual make target code. + +

    +
    +build:
    +        perl parse.pl ../../doc/loncapafiles/loncapafiles.html build > Makefile.build
    +        make -f Makefile.build all
    +
    +
    + +loncom/build/parse.pl reads in all the build information out +of doc/loncapafiles/loncapafiles.html. A new Makefile named +loncom/build/Makefile.build is dynamically constructed. +This dynamically generated Makefile is then run to build/compile +all the software targets from source. This currently takes 10 minutes +(depends on the speed of the machine you compile with). +

    +Example +

    +Here is information for one file tth.so provided in +doc/loncapafiles/loncapafiles.html. + +

    +
    <METAGROUP> +
    <LONCAPA TYPE=LOCATION DIST="redhat6.2" SOURCE="loncom/modules/TexConvert/tthperl/tth.so" TARGET="usr/lib/perl5/site_perl/5.005/tth.so" CATEGORY="system file"> +
    <DESCRIPTION> +
    shared library file for dynamic loading and unloading of TeX-to-HTML functionality +
    </DESCRIPTION> +
    <BUILD> +
    loncom/modules/TexConvert/tthperl/commands +
    </BUILD> +
    <DEPENDENCIES> +
    ../tthdynamic/tthfunc.c +
    ../ttmdynamic/ttmfunc.c +
    </DEPENDENCIES> +
    + +loncom/build/parse.pl sees the BUILD tags and sets up +a dynamic file Makefile.build to run the command inside the +BUILD tags (currently, DEPENDENCIES is not used for anything +besides documentation). +

    +

    +Here is an example of a dynamically generated Makefile.build +that builds two LON-CAPA files (one of which is tth.so. + +

    +all: ../homework/caparesponse/capa.so ../modules/TexConvert/tthperl/tth.so 
    +
    +../homework/caparesponse/capa.so:  ../homework/caparesponse/caparesponse.c ../ho
    +mework/caparesponse/caparesponse.pm alwaysrun
    +        cd ../homework/caparesponse/; sh ./commands
    +
    +../modules/TexConvert/tthperl/tth.so:  ../modules/TexConvert/tthperl/../tthdynam
    +ic/tthfunc.c ../modules/TexConvert/tthperl/../ttmdynamic/ttmfunc.c
    +        cd ../modules/TexConvert/tthperl/; sh ./commands
     
    +alwaysrun:
    +
    + +

    +
  4. +

    Adding/removing files from the LON-CAPA installation (doc/loncapafiles/loncapafiles.html)

    +
  5. +

    Configurable files versus non-configurable files

    +
  6. +

    Updating the non-configurable files on your machine (make install)

    +
  7. +

    Updating the configurable files on your machine (make configinstall)

    +
  8. +

    Building RPMs (make RPM)
