This is some early thoughts on the process of building LIBC and the other tools in the LIBC repository. People with better english skills and first hand experience in doing this stuff from scratch are welcome to help filling in the gaps. = Select Source Tree = Before even checking out the sources, you have to decide which sources to get. There are the following options: * The trunk - development branch. url: http://svn.netlabs.org/repos/libc/trunk/ [[BR]]Choose this if you are interested in helping out with/on new features and make the new world a better place. * The libc-0.6 branch - release branch. url: http://svn.netlabs.org/repos/libc/branches/libc-0.6/ [[BR]]Choose this if you are out for bugfixing in or backporting bugfixes to in this release, of if you are simply hunrgy from something to build. [[BR]]This is also the right choice if you want something which is 100% sure to be usable. * The libc-0.5 branch - old release branch. url: http://svn.netlabs.org/repos/libc/branches/GCC_3-2-2_BETA4_BRANCH/ [[BR]]Choose this if you have critical bugs which needs fixing in the 0.5 release. Only critical fixes are accepted. = Checking Out The Tree = First you need a copy of subversion for OS/2 available here http://silk.apana.org.au/subversion/ Installation is as simple as copying the binaries to your PATH and having a HOME directory set. Create a folder, perhaps Innotek_libc, cd into it and enter svn -co URL so to pull the trunk the command would be svn -co http://svn.netlabs.org/repos/libc/trunk which will create a directory called trunk and mirror the Netlabs trunk repositry. For other interesting targets see Select Source Tree. If you check out the thunk you will need kBuild. kBuild is not converted to svn yet, so you'll have to dig up a working cvs client. What to do: 1. Go to the root dir in the trunk checkout. 1. cvs -d :pserver:guest@cvs.netlabs.org:/netlabs.cvs/kbuild login [[BR]]Password: readonly 1. cvs -d :pserver:guest@cvs.netlabs.org:/netlabs.cvs/kbuild co kBuild = Setting Up The Build Environment = This is gonna be difficult to explain. esp. since I'm using a clash together mixup here... == Required Tools == 1. Latest GCC release. Check ftp://ftp.netlabs.org/pub/gcc/ [[BR]] N.B. For building the 0.5 branch you should probably use the latest 3.2.2 release from http://www.innotek.de/products/gccos2/download/gccos2download_e.html 1. Latest GNU Make 3.81 beta available at http://www.unixos2.org/sw/pub/binary/make/make-3.81beta3-r2-bin.zip. TODO: Build this with libc-0.6 and find somewhere to put the build. 1. .... = Doing The Build = The instructions differents between the trunk and the branches. The repository is begin reorganized after the libc-0.6 release branch was created and is currently in the process of being switched over to a different build system (at least the non gnu bits). == Building The Trunk == You have two choices, build everything or just a single component. When building single components you go into the root directory for that component. For libc that means /libc. libc and emx are currently in an intermediate shape buildsystem wise, and you'll have to specify the makefile on the make commandline: {{{ make -f Makefile.gmk }}} This will print a menu of the make goals. The {{{ all }}} and {{{ install }}} goals are choices you can't go wrong with. Building gcc and binutils means using the GNU buildsystem. Explain about the GNU buildsystem, blah blah blah. = About Releasing = It is not permitted for anyone other than the release engineer (i.e. bird) to publish libc builds using the natural series of dll names, since this will cause confusion among users and incompatibility between the official releases and your releases. Not complying with this simple rule is a sure way of pissing people of, at least bird. The natural series is expressed by this regexp '/^libc[0-9][0-9][0-9]*[abr]*[0-9]*\.dll$/'. Examples: libc05.dll, libc06.dll, libc06a1.dll, libc06b4.dll, libc06r2.dll, libc07r1.dll, libc10.dll, and libc100a.dll Documenting your build is vital. It should be made '''__exceptionally__''' clear that the build is '''__not__''' an official one, that '''__you__''' did it, what is special about your build, what it includes which is different from the official ones, and how to reconstruct the '''__sources__''' (diff + what you diffed against or/and subversion tree revision(s)). It is also worth keeping in mind that LIBC is '''LGPL''' and most of the other stuff is '''GPL''' (the exceptions are ash,.. which are BSD). So, don't forget to include '''COPYING.LIB''' and/or '''COPYING''' when appropriate.
