It was working on Solaris 11.3, but there were still problems
building on Solaris 11.4 with GCC (as on the evaluation VM
downloaded directly from Oracle):
1. ksh immediately segfaulted. Experimenting with the compiler
flags Oracle uses revealed that we need to define _XPG6 for ksh
not to segfault. Why is a mystery.
2. The default path logic used by 'command -p' and the 'getconf
PATH' builtin command was still broken: the result did not
include any of the /usr/xpg?/bin directories where the standard
POSIX utilities actually live. Testing shows that the result of
the C language probe 'confstr(_CS_PATH,name,length)' is broken
on Solaris (it only yields the paths to the historic
non-standard utilities, defeating the purpose) unless _XPG7 is
defined; but the latter makes ksh segfault again. So another
solution is needed.
src/cmd/INIT/package.sh, bin/package:
- Add another hack to add the -D_XPG6 flag to CCFLAGS if we're
running SunOS aka Solaris. (I've tried to add a 'cc.sol11' script
to src/cmd/INIT/ instead, but for some reason that I just don't
have time to figure out, the INIT system ignores that on Solaris
with gcc, so this is the only way I could come up with. Any
patches for less hacky alternatives would be welcome.)
src/lib/libast/comp/conf.sh:
- Sanitise the code for finding the best 'getconf' utility.
src/lib/libast/comp/conf.tab: PATH:
- Since the C-languge getconf(_CS_PATH,...) is broken on Solaris
11.4, replace the C language probe with a shell script probe that
uses the external 'getconf' utility.
- To avoid ksh overriding the result of this probe with the result
of its own getconf(_CS_PATH,...) call, which would make Solaris
use the wrong value again, specify this as an AST configuration
entry instead of a POSIX entry. This should be good enough for
all systems; the OS 'getconf' utility should be reliable and the
default path value is constant for each OS, so can be hardcoded.
src/cmd/ksh93/tests/builtins.sh:
- Add another 'sleep .1' to the 'sleep -s 31' test as it was still
intermittently failing on Solaris and possibly other systems.
