Interpreted Version of PolyML 4.1.3
by brucker＠spamfence.net 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

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).

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?

Segfault on 2.6.9 SMP
by Martin.vGagern＠gmx.net 13 Dec '04

13 Dec '04

Hello! I know this problem was already mentioned in two threads. Still I have additional information. Addition to "Segfault on SMP Linux kernels": I get those problems on the /third/ call to ReserveAddressSpace: (compiled with -O0, otherwise ReserveAddressSpace will be inlined) #0 ReserveAddressSpace (addr=0x3f000000 <Address 0x3f000000 out of bounds>, len=8192) at mmap.c:364 #1 0x080591fe in ReserveMLSpace ( bottom=0x3f000000 <Address 0x3f000000 out of bounds>, top=0x3f002000 <Address 0x3f002000 out of bounds>) at mmap.c:378 #2 0x080592f1 in ReserveMLSpaces () at mmap.c:406 #3 0x080521f3 in main (argc=1, argv=0xbfffe4f4) at mpoly.c:710 Addition to "Seg. fault - 2.6.9 kernel": I have a plain vanilla 2.6.9, no patches. Still this does not work for me. I have a gentoo distribution, maybe you want to keep an eye on the related gentoo bug report as well: http://bugs.gentoo.org/show_bug.cgi?id=35548 I only had a rather brief look at the source code, but is there a special reason why the mmapped area should be at a fixed address? Greetings, Martin von Gagern

Segfault on SMP Linux kernels
by plam＠MIT.EDU 01 Dec '04

01 Dec '04

Hi all, I was trying to run polyml on a machine running a 2.6.9-smp kernel. Unfortuantely, it just segfaults when it tries to mmap, in particular at the second call to ReserveAddressSpace in mmap.c: caddr_t pa = mmap((caddr_t)addr, len, PROT_NONE, MAP_PRIVATE | MAP_FIXED | MAP_NORESERVE | MAP_ANONYMOUS, -1, 0L); System details: 1G of RAM, Debian unstable, libc6 2.3.2.ds1-18, kernel 2.6.9-smp. It does not crash when I use the 2.6.8 non-smp kernel. Thanks for any help. pat

Turning off printing of exceptions
by rda＠lemma-one.com 04 Nov '04

04 Nov '04

I have a recollection that there is a way of stopping Poly/ML printing out the exception value when an excepation is raised but not caught, but I can't find anything in the structure PolyML that looks likely to do this. Am I mistaken or am I overlooking something? Regards, Rob.
