Merge Perry Metzger "netbsd patches" sbcl-devel 2004-04-06 ... don't merge SB_THREAD/spinlock cleanup; the right answer is to define an almost-null get_spinlock() version for non-threaded builds.

GENERAL INFORMATION
|
|
|
|
Welcome to SBCL.
|
|
|
|
To find out more about who created the system, see the "CREDITS" file.
|
|
|
|
If you'd like information about the legalities of copying the system,
|
|
see the "COPYING" file.
|
|
|
|
If you'd like to install or build the system, see the "INSTALL" file.
|
|
|
|
If you'd like more information about using the system, see the man
|
|
page, "sbcl.1", or the user manual in the "doc/" subdirectory of the
|
|
distribution. (The user manual is maintained as DocBook SGML in the
|
|
source distribution; there is an HTML version in the binary
|
|
distribution.)
|
|
|
|
The system is a work in progress. See the "TODO" file in the source
|
|
distribution for some highlights.
|
|
|
|
If you'd like to make suggestions, report a bug, or help to improve the
|
|
system, please send mail to one of the mailing lists:

SYSTEM-SPECIFIC HINTS
|
|
|
|
for NetBSD:
|
|
NetBSD 2.0 and above are required because of the lack of needed
|
|
signal APIs in NetBSD 1.6 and earlier.
|
|
|
|
for OpenBSD:
|
|
OpenBSD 3.0 has stricter ulimit values, and/or enforces them more
|
|
strictly, than its predecessors. Therefore SBCL's initial mmap()
|
|
won't work unless you increase the limit on the data segment from
|
|
the OpenBSD defaults, e.g. with
|
|
ulimit -S -d 1000000
|
|
before you run SBCL. Otherwise SBCL fails with a message like
|
|
"ensure_space: failed to validate xxxxxxx bytes at yyyyy". (SBCL
|
|
is just allocating this huge address space, not actually using this
|
|
huge memory at this point. OpenBSD <3.0 had no problem with this,
|
|
but OpenBSD 3.0 is less hospitable.)
|
|
|
|
for Darwin:
|
|
PURIFY (which can be used alone but is also used by the system when
|
|
saving a new core) uses more stack than the default limit on MacOS
|
|
X.2. Therefore, in order to get PURIFY to work reliably, you need
|
|
to increase the limit, with e.g.
|
|
limit stack 8192 # for the default shell, tcsh
|
|
ulimit -s 8192 # for bash
|
|
before running SBCL. This is also necessary when building the system
|
|
from sources, as part of the build process involves saving a new core.
