Why is this happening? An (nth 6 (sys-info)) used to return the version number of newLisp (here 9217).

Still works over here on Mac OS X, Free BSD 4.9 and Linux 2.6

what kind of Linux are your running? The above Linux is a custom Amazon Ec2 services Linux, RedHat based.

Can you do a uname -a to fined out? Do previous versions give the same error?

ps: and what makefile did you use to compile, if this is a 64-bit Linux, then you can compile as either 32bit or 64bit Linux. That big number should be 2038 (stack depth)

It is the 64 bit version of Slackware Linux 12.0 called 'SLAMD' (www.slamd64.com).

peter@AsteroidRider:~$ uname -a
Linux AsteroidRider 2.6.22.8 #1 SMP Tue Sep 25 20:41:25 BST 2007 x86_64 x86_64 x86_64 GNU/Linux

I have compiled newLisp as follows:

make -f makefile_linux_readline

If I run 'make', it will automatically use the 'linux_makefile' version.

Assuming that it has 32-bit libs installed, try using:

Code: Select all

make -f makefile_linux64ILP32

if that doesn't work do:

Code: Select all

make -f makefile_linux64LP64

but the first will most likely work, most 64-bit Linux are configured with two sets of libraries, and the header of the binary lets the loader automatically choose the right one.

Lutz

ps: makefile_linux64 is the same as makefile_linux64ILP32

Posted: **Thu Jan 24, 2008 6:20 am**

The first makefile does not work at all:

make: *** No rule to make target `makefile_linux64LP32', needed by `newlisp.o'. Stop.

The second makefile works, but there is no difference:

Later I saw your remark:

makefile_linux64 is the same as makefile_linux64ILP32

The 'makefile_linux64ILP32' does not work:

But the 'makefile_linux64' does work:

Now the (sys-info) and the (nth) and also implicit indexing are working correctly!

From C compilation point of view it seems to come down to the '-m32' flag which is missing in the other situations...?

Hm, I cannot import 64-bit libraries anymore with this last compilation:

newLISP v.9.2.17 on Linux, execute 'newlisp -h' for more info.

> (import "libgtk-server.so" "gtk")

problem loading library in function import : "libgtk-server.so: wrong ELF class: ELFCLASS64"

This used to work with the plain 'makefile_linux', I can run all my GTK-server apps in 64bit. Obviously I do not use 'nth' that much.

You have to locate the 32-bit libraries on that machine, when you run newLISP as a 32-bit app.

running 64-bit newLISP with nth does it fine on OS X:

Code: Select all

newLISP v.9.2.17 64-bit on OSX, execute 'newlisp -h' for more info.

> (nth 6 (sys-info))

Can you give me access to that machine? Also I wonder if this occurs only for sys-info. Can you run: ./newlisp qa-dot ? What about the whole test suite: make test ?

Big and Little where sitting on the wall... !!

Posted: **Thu Jan 24, 2008 9:55 pm**

Indeed, we think this maybe an Endian issue.

If I look to the datatypes in (sys-info), then it appears that the first elements are of type 'long' and 'size_t', each of which is 8 bytes. These are shown correctly.

Code: Select all

cell = stuffIntegerList(
	8,
	cellCount,
	MAX_CELL_COUNT,
	symbolCount,
	(UINT)recursionCount,
	(UINT)envStackIdx,
	MAX_CPU_STACK,
	version,
	opsys);

The problem starts when arriving at MAX_CPU_STACK, which is an int of 4 bytes. Also the 'version' is an int of 4 bytes.

There might be a problem aligning the bytes in memory. There are systems like the IA64 with 'switchable Endiannes', but I cannot find hard proof that this 64bit Intel machine has this feature. See also http://en.wikipedia.org/wiki/Endianness

Posted: **Fri Jan 25, 2008 12:28 am**

Seems to be a sign extension issue from 4 byte int to 8 byte unsigned long,

this should fix it:

Code: Select all

cell = stuffIntegerList(
    8,
    cellCount,
    MAX_CELL_COUNT,
    symbolCount,
    (UINT)recursionCount,
    (UINT)envStackIdx,
    (UINT)MAX_CPU_STACK,
    (UINT)version,
    (UINT)opsys);

because on 64 bit newLISP:

Code: Select all

> (format "%x" 140733193397249)
"2401"
> 0x2401
9217

ps: that machine seems to be turned off now, so I couldn't try myself
pps: there also may be 'import' issues

Hi Lutz,

Funny this 'signed-issue' does not occur in other places as well...?

The machine went to power saving and therefore was not reachable... sorry about that, it is available now for any further testing.
