Dear CLISP team,
I've recently built (vanilla) clisp-2.42 on MacOS X 10.5 (aka
Leopard). The resulting binary exhibited the infamous "Error 45"
problem [1], i.e. running
clisp | tee clisp.log # for example
yields the the following error message:
>
*** - UNIX error 45: Operation not supportd
(in an endless loop for CVS head even)
The MacPorts project [1] seems to work around this bug by compiling
clisp using
-D_NONSTD_SOURCE cflags. This however is an undesirable situation as
the include file /usr/include/sys/cdefs.h has the following to say
about this option:
/*
* COMPILATION ENVIRONMENTS
* [...]
* LEGACY Defining _NONSTD_SOURCE will get pre-POSIX APIs plus
Apple
* API extensions in scope.
*
* This is generally equivalent to the Tiger release
compilation
* environment, except that it cannot be applied to 64
bit code;
* its use is discouraged.
*
* We expect this environment to be deprecated in the
future.
* [...]
*/
The cause of the bug: Apple changed the value of EOPNOTSUPP to 102 in /
usr/include/sys/errno.h in the STANDARD compilation environment. This
seems to be due to the UNIX2003 certification that MacOS X 10.5 has
received. ENOTSUP however still is defined to be 45, and this is the
value the Darwin 9 kernel returns to user space. The problem can be
corrected by checking for both the ENOTSUP and the EOPNOTSUPP error
code in src/stream.d:
