Everything is moving to 64-bit environment and it's much easier to
have only one set of local libraries for free software.  For example
compiling something like xemacs I will need ten extra libraries and I
rather compile only 64-bit versions if I need these even once and
don't touch 32-bit stuff at all.

Firstly I thought you like to see how my environment is probed but you
like to get piece of code how to detect Sun 64-bit Forte compiler.

O.K., granted. But note, that it is not a simple. Currently zsh tries to
autodetect compiler flags (including those to enable LFS mode). But it does
it only if you did not explicitly specify any flags yourself. It is near to
impossible to write configure that wil parse e.g. LDFLAGS and infer
DLLDFLAGS. So, if you specify LDFLAGS you must specify DLLDFLAGS.

So, what you actually want is the way to specify "I want LP64 mode". It was
briefly discussed here when LFS support was added. The problem is, while LFS
support is more or less standardized (via getconf interface), there is no
standard way to enable LP64 mode. We'd end up listing every possible
combination of system/compiler.

Yes. I do not have either Solaris or Forte compiler so I cannot do it
myself. As said, either describe how your compiler can be detected or, if it
is confirmed that -KPIC is supported by all compilers on Solaris, we can
change it.

I have made some digging.  Oldest compiler I could find is 4.2 which
is quite old (cc: WorkShop Compilers 4.2 30 Oct 1996 C 4.2) and all
series 4 compilers are quite the same.  This old compiler knows -KPIC
-option and I also checked xemacs 21.4 configure and they use -KPIC
almost for every system available (irix/sysv4/unixware/solaris).
/opt/SUNWspro/bin/cc -cflags|grep -i pic
-KPIC           Compile position independent code with 32-bit addresses
-Kpic           Compile position independent code


Next thing is how to detect 64-bit.  Isainfo is quite good for this
and old compilers don't know anything about -xarch=v9 or v9a/v9b.
Only things that change for eg. on xemacs configure when using 64-bit
are size of long and void *

v9  Compile for the SPARC-V9 ISA.
v9a Compile for the SPARC-V9 ISA with UltraSPARC extensions.

So, what others think? Should we change it to -KPIC for Solaris?

No. Next thing is - why should zsh default to LP64 (that is what you mean.
Zsh already supports 64-bit atithmetic and large files)? Does it fix
something or adds new features?

It shouldn't; it should default to the default.

Erm ... do we need Solaris special-case? This changes it for all systems
using it.

I guess, yes. Especially as with this patch it is enough to just say
CC='cc -xarch-sparcv9'; no need to set individual flags.

No, we need gcc special-cased.  Which is already done.

This might work fine but is this correct way to give these
parameters.  I'm trying to find a way how to use autoconf/configure
with all softwares and sometimes there are also LD and CXX which will
need this same -xarch=v9 option so there should be a common flag or
option that delivers this throughout all places at once.

I think I used something along the lines of

CC='/opt/SUNWspro/bin/cc -xtarget=ultra2 -xarch=v9a' ./configure
and it was somewhat happy.

RE: Zsh 4.0.2 + 64bit Solaris 8 Forte 6.1 compiler

First, why would you want to compile zsh in 64 bit mode? Does your compiler
support long long in 32 bit mode?

Use (in addition to the above)

DLLDFLAGS=-xarch=v9

The same, give

DLCFLAGS=-KPIC

when configuring or

make DLCFLAGS=-KPIC ...

If you can provide a clean configure test to detect your compiler ...

Zsh 4.0.2 + 64bit Solaris 8 Forte 6.1 compiler

[Tomi Vainio - Sun Finland -]

Hi,

I have couple problems with zsh compile process.  I don't know how to
give correct parameters to configure process.  Compile will fail
because ./Makefile line 124 (LDFLAGS= ) is empty and it should contain
-xarch=v9.  I have tried to use these methods for configure but no
success yet.
CC=cc CFLAGS='-xO3 -xarch=v9' LDFLAGS='-xO3 -xarch=v9' ./configure
CC=cc ./configure --enable-cflags='-xO3 -xarch=v9' --enable-ldflags='-xO3 -xarch=v9'

`stamp-modobjs' is up to date.
rm -f libzsh-4.0.2.so
cc   -G -o libzsh-4.0.2.so  `cat stamp-modobjs` -lsocket -ldl -lnsl -lcurses -lm  -lc
ld: fatal: file builtin.o: wrong ELF class: ELFCLASS64
ld: fatal: File processing errors. No output written to libzsh-4.0.2.so

The second problem is with shared code.  ./configure line 6833
${DLCFLAGS=-Kpic} doesn't work and you should use -KPIC

`stamp-modobjs' is up to date.
rm -f libzsh-4.0.2.so
cc -xO3 -xarch=v9  -G -o libzsh-4.0.2.so  `cat stamp-modobjs` -lsocket -ldl -lnsl -lcurses -lm  -lc
ld: fatal: too many symbols require `small' PIC references:
        have 1552, maximum 1024 -- recompile some modules -K PIC.
