Category: pd-extended Group: v0.39.2 Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: bug in iemlib's for++ Initial Comment: There is a bug with the iemlib for++ object in PD- extended: I discovered a workaround to load for++ for now: 1. try to make an object [for++] - PD will say that there is no object like for++ 2. try to make an object [forpp] - PD will say that there is no object like forpp 3. try again to make an object [for++] - et viola , there is thefor++ I was looking for cheers, Nils -- Comment By: Nobody/Anonymous (nobody) Date: 2006-09-25 23:40 Message: Logged In: NO Not a fix, but another workaround: I've checked in a for++.pd abstraction, which is compatible with the IEMLIB-external. It's in the CVS at http://pure-data.cvs.sourceforge.net/pure-data/abstractions/purepd/ ciao -- fbar -- Comment By: Hans-Christoph Steiner (eighthave) Date: 2006-09-22 07:01 Message: Logged In: YES user_id=27104 This is most likely because the class name is for++, but the source filename is forpp.c. I think + is a valid character for the filesystem, otherwise it could be renamed using the hex loader. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detailatid=478070aid=1563095group_id=55736 ___ PD-dev mailing list PD-dev@iem.at http://lists.puredata.info/listinfo/pd-dev

[PD-dev] corelibs, build system
corelibs is currently broken due to a renaming of pd/src/d_mayer_fft.c to pd/src/d_fft_mayer.c while i updated the corelibs/generate.sh script to handle this, it still does not really work with the autobuild-system. the reason for this is (imo) the very complicated stacking of Makefiles (externals/Makefile vs. externals/corelibs/Makefile) which makes it impossible for a make-noob like me, to generate the .c files in the makefile while calling make in /externals (it does work fine when i do just make in externals/corelibs. the reason is, that CORELIBS_OBJECTS is evaluated before the files are generated (which would result in NO objects, since there should be no .c files before generation) a simple solution would be, to call make -c corelibs/ generate and then make -C corelibs/ from the externals/Makefile. obviously this does not work, since externals/corelibs/Makefile has no logic and instead uses externals/Makefile with the corelibs target (which would make my idea quite recursive). then again there is the horror of touching externals/Makefile at all: this huge file makes it quite hard/impossible to work on / fix several targets at the same time. e.g. yesterday i first worked on corelibs, then noticed that zexy won't build as it should, so i had to revert all the changes i had done to the Makefile (since it didn't yet work properly) so i could start fixing the zexy-build (which i understand better, and which i was pretty sure to be able to fix). so i ask this again: would it not be better to have the build-logic for each directory in a separate Makefile (which could be edited separately)? these Makefile could make use of a generic(!) Makefile which (e.g.) lives in externals/ this generic Makefile MUST NOT have any intelligence about the separate destination targets (e.g. no different logic for building corelibs or hid; just a generic build target); if such intelligence is needed, it should live in the projects subdirectory (externals/corelibs/Makefile) i would also like to know the exact reason for the pwd-magic (i just never ever needed such thing in any makefile i wrote, so i'm curious) mfg.asdr IOhannes ___ PD-dev mailing list PD-dev@iem.at http://lists.puredata.info/listinfo/pd-dev

Not sure of all the long-term ramifications, but I like the idea. Namespaces, anyone? ;) I think, externing over should be a feature on patch level. I'm thinking of something like the Python syntax for importing modules which basically has three forms: import zexy # builtin fft: fft() # zexy's fft has to be called with prefix: zexy.fft() from zexy import fftw # now fft() also calls zexy's fft: fft() from zexy import * # again zexy's fft shadows the builtin fft: fft() Ciao -- Frank Barknecht _ __footils.org_ __goto10.org__ ___ PD-dev mailing list PD-dev@iem.at http://lists.puredata.info/listinfo/pd-dev

Re: [PD-dev] missing file from pd-MAIN and fftw version
I should add, the next key step is to remove as many classes as possible from the root namespace (i.e. compiled into Pd). For many, it would be trivial to do, just compile them as individual objects in a libdir. I've already done this for x_list.c, x_net.c, and a couple others. Things like x_arithmatic.c will be trickier, but this does not have to happen at once. It can happen incrementally. .hc On Sep 26, 2006, at 9:41 AM, Miller Puckette wrote: Yes indeed.

Re: [PD-dev] missing file from pd-MAIN and fftw version
Using loading order will have similar problems whether you use the first loaded or the last loaded. And changing the order of precedence will have lots of unintended consequences. Modern programming languages use namespaces (C++, Python, Java, SmallTalk, etc). Namespaces are a much more appropriate and proven way to deal with this issue. Its already working in Pd on a basic level, and most of what's needed for a full-fledged namespace system is already implemented. .hc On Sep 26, 2006, at 9:41 AM, Miller Puckette wrote: Yes indeed.

Re: [PD-dev] corelibs, build system
IOhannes, PLEASE PLEASE PLEASE PLEASE PLEASE! ASK BEFORE YOU MESS WITH SOMEONE ELSE'S STUFF!!! This is one of the most basic and fundamental rules of working together, and you are violating this rule again and again, though we ask you not to! That is why we have this list. I am getting really tired of you breaking the stuff that I spent a lot of time setting up. I really don't want to have to use ACLs in CVS, but you are leaving me no other choice. corelibs is a section that I set up and only I have worked on so far. You did not ask at all. d_mayer_fft.c is the name of the file in 0.39.2. You have broken compilation for Pd-extended. - please revert all changes to the docs/developer section - please revert all changes to externals/corelibs Let's start over and do this right. .hc On Sep 26, 2006, at 5:02 AM, IOhannes m zmoelnig wrote: corelibs is currently broken due to a renaming of pd/src/ d_mayer_fft.c to pd/src/d_fft_mayer.c while i updated the corelibs/generate.sh script to handle this, it still does not really work with the autobuild-system. the reason for this is (imo) the very complicated stacking of Makefiles (externals/Makefile vs. externals/corelibs/Makefile) which makes it impossible for a make-noob like me, to generate the .c files in the makefile while calling make in /externals (it does work fine when i do just make in externals/corelibs. the reason is, that CORELIBS_OBJECTS is evaluated before the files are generated (which would result in NO objects, since there should be no .c files before generation) a simple solution would be, to call make -c corelibs/ generate and then make -C corelibs/ from the externals/Makefile. obviously this does not work, since externals/corelibs/Makefile has no logic and instead uses externals/Makefile with the corelibs target (which would make my idea quite recursive). then again there is the horror of touching externals/Makefile at all: this huge file makes it quite hard/impossible to work on / fix several targets at the same time. e.g. yesterday i first worked on corelibs, then noticed that zexy won't build as it should, so i had to revert all the changes i had done to the Makefile (since it didn't yet work properly) so i could start fixing the zexy-build (which i understand better, and which i was pretty sure to be able to fix). so i ask this again: would it not be better to have the build-logic for each directory in a separate Makefile (which could be edited separately)? these Makefile could make use of a generic(!)
