From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- boehm-gc/doc/README.autoconf | 59 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 boehm-gc/doc/README.autoconf (limited to 'boehm-gc/doc/README.autoconf') diff --git a/boehm-gc/doc/README.autoconf b/boehm-gc/doc/README.autoconf new file mode 100644 index 000000000..53fcf5a50 --- /dev/null +++ b/boehm-gc/doc/README.autoconf @@ -0,0 +1,59 @@ +As of GC6.0alpha8, we attempt to support GNU-style builds based on automake, +autoconf and libtool. This is based almost entirely on Tom Tromey's work +with gcj. + +To build and install libraries use + +configure; make; make install + +The advantages of this process are: + +1) It should eventually do a better job of automatically determining the +right compiler to use, etc. It probably already does in some cases. + +2) It tries to automatically set a good set of default GC parameters for +the platform (e.g. thread support). It provides an easier way to configure +some of the others. + +3) It integrates better with other projects using a GNU-style build process. + +4) It builds both dynamic and static libraries. + +The known disadvantages are: + +1) The build scripts are much more complex and harder to debug (though largely +standard). I don't understand them all, and there's probably lots of redundant +stuff. + +2) It probably doesn't work on all Un*x-like platforms yet. It probably will +never work on the rest. + +3) The scripts are not yet complete. Some of the standard GNU targets don't +yet work. (Corrections/additions are very welcome.) + +The distribution should contain all files needed to run "configure" and "make", +as well as the sources needed to regenerate the derived files. (If I missed +some, please let me know.) + +Note that the distribution comes with a "Makefile" which will be overwritten +by "configure" with one that is not at all equiavelent to the original. The +distribution contains a copy of the original "Makefile" in "Makefile.direct". + +Important options to configure: + + --prefix=PREFIX install architecture-independent files in PREFIX + [/usr/local] + --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX + [same as prefix] + --enable-threads=TYPE choose threading package + --enable-parallel-mark parallelize marking and free list construction + --enable-full-debug include full support for pointer backtracing etc. + +Unless --prefix is set (or --exec-prefix or one of the more obscure options), +make install will install libgc.a and libgc.so in /usr/local/bin, which +would typically require the "make install" to be run as root. + +Most commonly --enable-threads=posix or will be needed. --enable-parallel-mark +is recommended for multiprocessors if it is supported on the platform. + + -- cgit v1.2.3
