I would like to give the background on how the build system is designed and then give answers for the specific questions.
The build system provided with the VM is designed to be able to build the whole harmony codebase no matter how many modules it contains. The intent was to propose it later as a unified build system for the Harmony project after receiving the community feedback. The main notion the build operates with is a component - a more or less distinct part of product (vm, classlib, tools, etc). The benefits are: - A component can contain several types of source: C++ sources, C sources, assembler sources, Java* sources, smoke and unit tests. - A component can be processed in several ways in the build: produce native output (shared or static library or executable) and/or Java* classes in .jar file, produce and run smoke and/or unit tests. - One can switch between the different compilers and modes by using the environment variables, as follows: On Windows*: | On Linux*: -------------------------------------+---------------------------- MSVC compiler : set CXX=msvc | N/A Intel(R) compiler : set CXX=icl | export CXX=icc GCC compiler : N/A | export CXX=gcc Release : set BUILD_CFG=release | export BUILD_CFG=release Debug : set BUILD_CFG=debug | export BUILD_CFG=debug The build dynamically produces a build_${component}.xml file for each specific component by taking its descriptor, performing the attribute-based filtering on it, and then applying target templates and settings on it. The README describing how to write a component descriptor can be found at: harmony/enhanced/drlvm/trunk/README.txt Here are the answers on questions: Component-oriented build system is designed to support project layout this way : /drlvm/ /classlib/ /tools/ /deploy/ The external resources such as APR, ECLIPSE, CPPTASKS, ZLIB, etc are described in enhanced/drlvm/trunk/build/make/win.properties and enhanced/drlvm/trunk/build/make/linux.properties for each system respectively. Each network resource location is configured as follows: remote.<resource name>.archive=<Resource URL or local path to zip archive> Which can be overridden through the system environment as follows: <resource name>_HOME=<extracted archive location> For example, the build takes Eclipse from it's default location on Windows: remote.ECLIPSE.archive=http://mirrors.cat.pdx.edu/eclipse/eclipse/downloads/drops/R-3.1.1-200509290840/eclipse-JDT-3.1.1.zip unless the ECLIPSE_HOME is set and points to the Eclipse installation directory. The "build update" command downloads resources only once. It may be overridden by setting <resource name>_HOME=<extracted archive location> variables. The build is invokable from above by calling build.bat or build.sh depending on the operating system. It is possible to specify only certain compnent(s) to build: build.bat -DCOMPONENTS="vm extra classlib" However, currently vm component is rigidly dependent on classlib and will initiate classlib building. I can't provide the patch to unhook vm and class libs today, but please allow a bit more time, and the patch will appear. -- Denis Sharypov, Intel Middleware Products Division On 6/8/06, Geir Magnusson Jr <[EMAIL PROTECTED]> wrote:
oh. Well, I'll try that - it's a step forward. I do think we need to rapidly come to a conclusion on what to do. I think we want to have the drlvm build : 1) point anywhere to a hdk/classlib that's prebuilt and just use the artifacts in it 2) be invokable from 'above' (as described below) 3) change how the dependencies work. I think it's nice to be able to do what it does, but we also need to have the ability to keep those around locally indep of drlvm, and just use properties to tell drlvm where to find those resources too, so that way if I have a regular distribution of say APR on my machine, I can just use it. Now, this is something for all of us to decide, but I imagined our project this way : /drlvm/ /classlib/ /tools/ /deploy/ with each 'subcomponent' (i.e. classlib, drlvm, jchevm) determining it's own build and just having a clear way to be invoked form above. We can then invoke the classlib build and have it deposit it's artifacts into the deploy directory, and then point drlvm to that and have it build from there - and NOT build classlib. Further, building on the HDK stuff, I think we'd also want to be able to do something like : /drlvm/ /hdk/ hdk1/ hdk2/ and point drlvm to build against one of the hdks.... I really appreciate how easy the existing build makes evaluation of drlvm, but we should consider if we can reuse to get us towards the above, or if we have to re-do in a manner more like classlib, jchevm, etc... geir Vladimir Gorr wrote: > Geir, > > unfortunately the DRLVM build system doesn't allow to make you wish. > Obviously it should be modified to build the recent version of class > library > from SVN > using the original build system.
