Help with creating executable
by Vijay Mathew 19 Aug '11

19 Aug '11

Hi, I am trying to generate an executable from a Scheme file: ;; hello.ss (display "hello world") (newline) On Ubuntu Linux (11.4, 32bit) with Gambit v4.2, I tried the following command: $ gsc -o hello -exe hello.ss It failed with a warning "misplaced option -exe". On Windows 7 (64bit) with Gambit v4.6.1, I get the following error: $ gsc -o hello.exe -exe hello.ss Access is denied. Access is denied. Access is denied. *** ERROR IN ##for-each -- No such file or directory (delete-file "C:\\Users\\VMathew\\Desktop\\hello.o") On both machines the gcc compiler is installed and is working properly. I am following the directions at http://www.iro.umontreal.ca/~gambit/doc/gambit-c.html#GSC What could be going wrong? Thanks, --Vijay

Gambit under QNX 4.25
by Кириенко Олег 16 Aug '11

16 Aug '11

Hi, I have tried to compile Gambit under QNX 4.25 (not QNX 6) and get error during configure stage checking for sys/types.h... /tmp/sh23124234: cannot open file (No such file or directory). It seems that configure script doesn't run properly in QNX 4.25 which is very limited realtime POSIX system. I have a general question is it possible to build Gambit in system: 1. that doesn't support automake/autoconf properly 2. that does not have so/dll 3. that doesn't have threads (pthread for instance) Is it possible to write manually config.h is such a way? In general I want to develop under Linux but run/test everything under QNX 4.25. QNX 4.25 supprorts tcp/ip sockets so this is the only requirement for me except standart c functions. Oleg.

It compiles it 3 times (i386 for the simulator, and armv6 and armv7 for the real devices), and combines the libraries using "lipo". I just got around to pulling the latest changes and trying them. They don't appear to work with the latest (Lion) version of the Apple dev tools. Whether trying a configure and make on the root (to build the Max OS X version of Gambit) or cding into examples/iOS and running the build-gambit-iOS script, the build fails with a complaint about a version mismatch between gambit.h and the C sources produces by the gambit compiler. --me

What variables are not optimized away by (declare (not optimize-dead-local-variables))?
by Mikael 12 Aug '11

Dear Marc, If I got the manual right, the object file below is compiled in such a way that the (not optimize-dead-local-variables) is completely effective. Even so, the c variable is not reproduced by ,be . Regarding this I wonder, in this example is this option enabled as it should (I suppose so), and if so, approx what variables are not optimized away when this declare is enabled? (I mean, now that c was optimized away, approx which can be expected not to be optimized away.) If there is some way to get /virtually/ all dead variables not optimized away also in compiled mode it would be very valuable. Thanks, Mikael $ cat a.scm (declare (not optimize-dead-local-variables)) (define (b) (let ((c 5)) c (/ 0 0) 7)) $ gsc Gambit v4.5.3 > (compile-file "a.scm" options: '(debug)) "/tmp/a.o1" > (load "a.o1") "/tmp/a.o1" > (b) *** ERROR IN b, "a.scm"@5.1 -- Divide by zero (/ 0 0) 1> ,be 0 b "a.scm"@5:1 (/ 0 0) 1 (interaction) (console)@3:1 (b) 1>

Gambit Scheme and Slime
by Matt Lamari 12 Aug '11

12 Aug '11

I am us the swank at https://github.com/jlongster/swank-gambit?id=h73kq and 4.6.1 Fixed what looked like a little bug where it's returning its modules list ( un-backquoted variable) If I run swank-gambit.scm from 4.6.1 gsi, emacs can connect, complains of version mismatch, then hangs indefinitely. Before digging any deeper, is there some big configuration thing I'm missing? Does anyone have this working? What versions? What's a surefire trick to get Emacs+Slime talking to Swank on a Gambit Scheme?

Gambit for Android version 0.2 Released
by Keith Flower 12 Aug '11

12 Aug '11

A new version (0.2) of Gambit for Android has been released on the Android Market: https://market.android.com/details?id=org.keithflower.gambit You can read more about Gambit for Android here: http://apps.keithflower.org/?page_id=152 Thanks to Steve Graham, Alexander Shendi, Marc Feeley, and others for valuable feedback and suggestions on this version. Features added: A native code crash triggers optional email to the developer with a description and stack backtrace (Java-side problems are already automatically reported). Adding a new script adds to the beginning of the script list, rather than to the end. User can start the REPL server from the Android menu. Bug fixes: Some Java-Native Interface functions were serialized to prevent thread contention. Fixed REPL window backspace problem, which caused a StringIndexOutOfBoundsException. Changed aviation weather script example - NOAA seems to have altered its web interface. Added Gambit tests to the Android version test suite: r4rstest.scm mix.scm debug.scm error.scm What I'm currently working on: Incorporating Gambit (iOS) v2.0 changes. Adding user interface preferences, e.g., choose REPL window font size. Migrating source to Gambit git repository.

Problem building Gambit from scratch
by Matt Lamari 11 Aug '11

11 Aug '11

I was actually trying to build for the iOS; but this actually repeats on Ubuntu 64 as well, both fail in same spot before going to examples at all On the mac OSX, GCC 4.2.1, On Ubuntu, GCC 4.4.3 On either: % WGET/CURL "http://www.iro.umontreal.ca/~gambit/download/gambit/v4.6/source/gambc-v4_6_…" % tar ... % cd gambc-v4_6_0-devel % ./configure --enable-single-host % make -j 2 % make update Is there something I'm doing wrong? They both fail on _io.o with the following type error gcc -Wno-unused -O1 -fno-math-errno -fschedule-insns2 -fno-trapping-math -fno-strict-aliasing -fwrapv -fomit-frame-pointer -fPIC -fno-common -mieee-fp -I"../include" -c -o "_io.o" -I. -DHAVE_CONFIG_H -D___GAMBCDIR="\"/usr/local/Gambit-C\"" -D___SYS_TYPE_CPU="\"x86_64\"" -D___SYS_TYPE_VENDOR="\"unknown\"" -D___SYS_TYPE_OS="\"linux-gnu\"" -D___CONFIGURE_COMMAND="\"./configure --enable-single-host --no-create --no-recursion\"" -D___OBJ_EXTENSION="\".o\"" -D___EXE_EXTENSION="\"\"" -D___BAT_EXTENSION="\"\"" -D___PRIMAL _io.c -D___LIBRARY In file included from ../include/gambit.h:12, from _io.c:1343: ../include/gambit-not406001.h:1:2: error: #error "The version indicated in ___VERSION is not supported by gambit.h" ../include/gambit-not406001.h:2:2: error: #error "You are probably compiling C code generated by a Gambit compiler earlier or later than v4.6.1" ../include/gambit-not406001.h:3:2: error: #error "___VERSION will be set to 406001 to reduce other errors" make[2]: *** [_io.o] Error 1 make[2]: Leaving directory `/home/blahblahblah/t/gambc-v4_6_0-devel/lib' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/blahblahblah/t/gambc-v4_6_0-devel' make: *** [update] Error 2

For example, it was a complicated task to have compiler pluginsin gcc as LLVM has. R.Stallman resisted this new gcc feature for some time, it is now part of the gcc feature set. --Alex - Mtl
