Hello Gustaf, Tried compiling NX today and it is failing. I am on Linux 64bit this time, 3.2.0-8-generic kernel, compiling against latest TCL 8.6 Fossil source. Make fails with the following error: ..... gcc -DPACKAGE_NAME=\"nsf\" -DPACKAGE_TARNAME=\"nsf\" -DPACKAGE_VERSION=\"2.0b3\" -DPACKAGE_STRING=\"nsf\ 2.0b3\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_LIMITS_H=1 -DHAVE_SYS_PARAM_H=1 -DHAVE_TCL_COMPILE_H=1 -DNSF_WITH_ASSERTIONS=1 -DUSE_THREAD_ALLOC=1 -D_REENTRANT=1 -D_THREAD_SAFE=1 -DTCL_THREADS=1 -DMODULE_SCOPE=extern\ __attribute__$\(__visibility__\(\"hidden\"$\)\) -D_LARGEFILE64_SOURCE=1 -DTCL_WIDE_INT_IS_LONG=1 -DUSE_TCL_STUBS=1 -DCOMPILE_NSF_STUBS=1 -DNSF_VERSION=\"2.0\" -DNSF_PATCHLEVEL=\"2.0b3\" -I"/root/tcl-source/generic" -I"/root/tcl-source/unix" -I./generic -g -O2 -pipe -O2 -fomit-frame-pointer -Wall -fPIC -c `echo ./generic/nsfStubLib.c` -o nsfStubLib.o rm -f libnsfstub2.0b3.a ar cr libnsfstub2.0b3.a nsfStubLib.o ranlib libnsfstub2.0b3.a TclStackFree: incorrect freePtr (0x7fffc7179500 != 0xedabd0).

Mingw correction
by Vasileios Anagnostopoulos 04 Jan '12

04 Jan '12

Hi, I downloaded the nsf2.0b2 and tried to compile under latest msys/mingw on WINDOWS XP SP3. The only showstopper was on nsfAPI.h where I included nsfInt.h and a correction in line 227 of nsfInt.h where #ifndef __WIN32__ should be replace with #if (defined __WIN32__) && !( defined __GNUC__) The resulting binary executed (after setting TCLLIBPATH) the samples on the site. One more question, will we see XotclIDE love with XoTCL 2?

[NX] Passing arguments to an object's constructor
by Arthur Schreiber 29 Nov '11

29 Nov '11

Hello everyone, Is there any way to pass arguments to the init method in NX (as in XOTcl)? Or is using object parameters on initialization the preferred way in NX to initialize an objects instance variables? Thanks, Arthur

Next Scripting Framework
by Gustaf Neumann 27 Oct '11

27 Oct '11

Dear XOTcl community, today, we presented the Next Scripting Framework (NSF) at the 8th Annual Tcl/Tk Conference at Manassas, Virginia. We are proud to announce also here the availability of nsf 2.0b2, available from the web-site below, that went as well public today. The release plan is to gather in the first round feedback from the inner community and to polish the website and documentation in the meantime. The full public release will come out without the beta-state and will be annouced to the wider public. The distribution of the next scripting framework contains essentially - NSF, the low-level framework - XOTcl 2.0 - NX (descendant of XOTcl) While XOTcl 2.0 is primarily highly compatible with XOTcl 1.6, NX provides more support for programming the larger, such as stronger encapsulation, method protection, modular feature composition, etc. For more details, consult the slides referenced below. The website contains a more detailed NX migration guide comparing XOTcl idioms with NX idoms, or an NX tutorial. The Next Scripting Framework requires Tcl 8.5 or newer and is released under an MIT license. For users bound for the time being to Tcl 8.4 we will continue to release bug fixes for the XOTcl 1.6 series. web-site: http://next-scripting.org/ slides: http://nm.wu-wien.ac.at/research/publications/b885.pdf Gustaf Neumann Stefan Sobernig -- Univ.Prof. Dr. Gustaf Neumann Institute of Information Systems and New Media WU Vienna Augasse 2-6, A-1090 Vienna, AUSTRIA

NX memory leak
by Kristen Eisenberg 23 Oct '11

23 Oct '11

Hello Gustaf, I am using the latest Tcl 8.6 from SourceForge and latest NX on 32bit Linux. I am experiencing a pretty bad memory leak when using NX objects with attributes. Example code: time {Object create o; o attribute "[clock clicks] [clock clicks]";o destroy} 1000000 Within like 3 minutes the memory usage grows to around 300meg.
