Poly/ML and the SML'97 Basis Library
by rda＠lemma-one.com 22 Jun '05

22 Jun '05

Trying to get ProofPower working against the a recent version (110.54) of Standard ML of New Jersey has flagged a few disccrepancies between the Basis Library as implemented in Poly/ML 4.1.3 and the documentation at http://www.standardml.org/Basis/history.html. What is the position for Poly/ML intended to be? (The discrepancies I found are in Array.copy and TextIO.inputLine which have different signatures. Poly/ML agrees with the so-called stable version 110.0.7 of SML/NJ, but as that's 7 years old, it's not a very useful implementation!). Regards, Rob.

Still getting strange behavior with Poly 4.13 on WinXP
by byron.hale＠einfo.com 10 Jun '05

10 Jun '05

Hi, I still get problems with unwanted environment retention on Windows XP. That wasn't the case in Fall 2003, so I'm wondering if the many Windows updates have resulted in an incompatibility with 4.13. I've even tried re-installing 4.13, but get the same behavior. It seems as if I've tried what seems like everything, except reinstalling 4.13 every time I want to have a fresh environment. Ideas? Thanks, Byron Hale

Poly/ML Licensing
by David.Matthews＠prolingua.co.uk 10 May '05

10 May '05

There has been some discussion about the Poly/ML licence and the fact that it is "non-standard" and so causes problems with including it in open-source distributions. I have now received permission from CUTS, the copyright holders for the bulk of Poly/ML, to issue Poly/ML under the Lesser GPL. This seemed the best choice as it allows any commercial users to distribute a binary-only version with their software. I will update the web-site shortly and change the source code to refer to LGPL rather than the Poly/ML licence for the next release. I'm currently working on updating the basis library to match Gansner and Reppy's book. Once that's completed there will be a new release. Thanks to Larry Paulson and Mike Gordon for their assistance in negotiating with CUTS. David Matthews.

Seg. fault

FYI, Lest anyone be planning an upgrade, I get segmentation faults on PolyML startup using Linux 2.6.9 (using PolyML as distributed with Isabelle). Maybe it's just me though. 2.6.8.1 seems fine though. Martin

Spontaneous corruption of PolyML 4.13 Database on WinXP
by byron.hale＠einfo.com 19 Mar '05

Hi, I'm sorry to report this, but the database on PolyML 4.13, Win XP, has saved state when I have studiously avoided doing so. Suggestions? Thanks, Byron Hale

Recursive type definitions resolved well enough for me.

Thanks to WIlliam Lovas, I have a reasonable answer for the errors I was getting and what might be done about them. SMLNJ seemed to handle errors more consistently than PolyML, but once there is a syntactic error, error handling is problematic anyway. Byron Hale

Interpreted Version of PolyML 4.1.3
by brucker＠spamfence.net 18 Mar '05

18 Mar '05

Hi, while trying to build an interpreted PolyML system based on version 4.1.3 (version 4.0 works fine) I'm getting linker errors, e.g.: /tmp/driver/improve.c:724: undefined reference to `MD_update_code_addresses' Any hints? Achim

Re: Compiling PolyML 413
by rdindir＠yahoo.com 03 Feb '05

I tried to install PolyML again... Here is what I did. Unpacked the driver archive: polyml-driver-4.1.3.tar.gz Then ran ./configure. It warned me about the operating system saying: "unknown operating system OpenBSD". And there are no XWindows support either (which is understanable because Xm is in different directories on my system, anyways). I continued and tried to compile it: make... There was a compilation error: discgc.c line 36 alloca.h (No such file or directory - NSFOD). Then I copied the part where the OS is identified in the configure file for FREEBSD. The changes are like this: OpenBSD) echo "OpenBSD operating system" ARCH=`uname -m` OS=freebsd OSFLAGS=-DFREEBSD LIBS="-lm" ;; After that ran configure again, which removed the warning regarding the operating system. Then tried to compile it again (first make clean, then make). There were again errors which I have changed like this... 1. mmap.c: 66 values.h (No such file or directory). I commented out the include. There is no values in my system. I tried to find it. Maybe I have to find the corresponding header file for this. In the mmap.c file there is a comment that says that FREEBSD warns about that particular file. Since there is a warning I commented it out. There is a file /usr/include/limits.h that defines the constants defined in values.h on other systems. I will try to include this file and compile again... But since it compiles without this file, the constants must be defined somewhere... Anyways here are the remaining steps that I have taken. 2. reals.c: 24 floatingpoint.h (NSFOD). I have changed this include to ieeefp.h, which is on my system. No floatingpoint.h present. floatingpoint.h on FreeBSD is for IEEE fp functionality. 3. realconv.c: warnings here. Ignored. after these changes I compiled again (make clean and then make). Compiled fine. Installed the polyML using make install. Then I continued and created a temp directory and unpacked the polyml-4.1.3.i386.tar.gz database to the directory created. It created a DB413Release and a link ML_dbase. In the same directory I ran poly and it gave me this message: Can't process signal at 2071acee and poly.core created (core dumped). By the way, my system is (using uname -srv): OpenBSD 3.4 GENERIC #18 Riza > Date: Thu, 27 Jan 2005 11:00:37 +0000 > From: David Matthews > > It's almost impossible to suggest anything here > without a lot more > information.

Compiling PolyML 413
by rdindir＠yahoo.com 27 Jan '05

27 Jan '05

Hi All, I have a problem with polyml (poly), when I try to start it. The ML_dbase as well as the the poly executable is in the current directory. When I start it displays this message: Can't process signal at <an address or hex number> Here is what I did... I obtained the source for polyML polyml_driver_4.1.3.tar. Changed the addresses in the addresses.h file. I gotton the address from mmap function and mapped the values in the header file. Compiled the driver on OpenBSD. Compacted the database for the i386 architecture. All went well with no problems, but I get the above message and the executable dumps a core. Do I do something wrong (aparently I do) something in the above procedure to compile and create the database. I also tried to build a new database, using readport but I could not get it to compile. It complains about the definition OBJ_FIRST_BIT. I do not remember the other errors... Kind Regards, Riza Dindir __________________________________________________ Do You Yahoo!? Tired of spam?
