| 1 | As of GC6.0alpha8, we attempt to support GNU-style builds based on automake,
|
|---|
| 2 | autoconf and libtool. This is based almost entirely on Tom Tromey's work
|
|---|
| 3 | with gcj.
|
|---|
| 4 |
|
|---|
| 5 | To build and install libraries use
|
|---|
| 6 |
|
|---|
| 7 | configure; make; make install
|
|---|
| 8 |
|
|---|
| 9 | The advantages of this process are:
|
|---|
| 10 |
|
|---|
| 11 | 1) It should eventually do a better job of automatically determining the
|
|---|
| 12 | right compiler to use, etc. It probably already does in some cases.
|
|---|
| 13 |
|
|---|
| 14 | 2) It tries to automatically set a good set of default GC parameters for
|
|---|
| 15 | the platform (e.g. thread support). It provides an easier way to configure
|
|---|
| 16 | some of the others.
|
|---|
| 17 |
|
|---|
| 18 | 3) It integrates better with other projects using a GNU-style build process.
|
|---|
| 19 |
|
|---|
| 20 | 4) It builds both dynamic and static libraries.
|
|---|
| 21 |
|
|---|
| 22 | The known disadvantages are:
|
|---|
| 23 |
|
|---|
| 24 | 1) The build scripts are much more complex and harder to debug (though largely
|
|---|
| 25 | standard). I don't understand them all, and there's probably lots of redundant
|
|---|
| 26 | stuff.
|
|---|
| 27 |
|
|---|
| 28 | 2) It probably doesn't work on all Un*x-like platforms yet. It probably will
|
|---|
| 29 | never work on the rest.
|
|---|
| 30 |
|
|---|
| 31 | 3) The scripts are not yet complete. Some of the standard GNU targets don't
|
|---|
| 32 | yet work. (Corrections/additions are very welcome.)
|
|---|
| 33 |
|
|---|
| 34 | The distribution should contain all files needed to run "configure" and "make",
|
|---|
| 35 | as well as the sources needed to regenerate the derived files. (If I missed
|
|---|
| 36 | some, please let me know.)
|
|---|
| 37 |
|
|---|
| 38 | Note that the distribution comes with a "Makefile" which will be overwritten
|
|---|
| 39 | by "configure" with one that is not at all equiavelent to the original. The
|
|---|
| 40 | distribution contains a copy of the original "Makefile" in "Makefile.direct".
|
|---|
| 41 |
|
|---|
| 42 | Important options to configure:
|
|---|
| 43 |
|
|---|
| 44 | --prefix=PREFIX install architecture-independent files in PREFIX
|
|---|
| 45 | [/usr/local]
|
|---|
| 46 | --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
|
|---|
| 47 | [same as prefix]
|
|---|
| 48 | --enable-threads=TYPE choose threading package
|
|---|
| 49 | --enable-parallel-mark parallelize marking and free list construction
|
|---|
| 50 | --enable-full-debug include full support for pointer backtracing etc.
|
|---|
| 51 |
|
|---|
| 52 | Unless --prefix is set (or --exec-prefix or one of the more obscure options),
|
|---|
| 53 | make install will install libgc.a and libgc.so in /usr/local/bin, which
|
|---|
| 54 | would typically require the "make install" to be run as root.
|
|---|
| 55 |
|
|---|
| 56 | Most commonly --enable-threads=posix or will be needed. --enable-parallel-mark
|
|---|
| 57 | is recommended for multiprocessors if it is supported on the platform.
|
|---|
| 58 |
