[02:43:17] <jepler> situation is: pdf docs build on 8.04 but only with the versions of asciidoc and dblatex I've backported from lucid to hardy. Soon (tomorrow?) I'll get them on the linuxcnc.org package server. If I understand the buildbot's setup, it should automatically pick them up, but if not I'm sure seb can fix it.
[02:43:29] <jepler> I still haven't done a full package build, I dunno if there are other roadblocks.

[15:46:25] <jepler> is it because it doesn't 'apt-get update' automatically?
[15:47:01] <seb_kuzminsky> it's my crappy script that tries and fails to install missing build dependencies

[15:47:31] <seb_kuzminsky> it runs dpkg-checkbuilddeps, in runs "apt-get install" on anything it complains about
[15:47:39] <seb_kuzminsky> but it doesn't handle versioned dependencies :-(
[15:47:45] <jepler> oh
[15:47:46] <jepler> I see
[15:48:13] <seb_kuzminsky> when building the deb inside pbuilder later it should all work fine, because pbuilder does that stuff correctly

[15:52:35] <seb_kuzminsky> cradek: yes i think so
[15:52:59] <cradek> whee
[15:53:02] <cradek> that makes me happy
[15:53:14] <seb_kuzminsky> i think if you push a commit that git-describes to a simple version number, it'll just automatically build it and it'll look like a real release
[15:54:06] <seb_kuzminsky> you can try it by making a "2.5.0-pre2" practice release and we'll see if it does it right
[15:55:26] <seb_kuzminsky> i think the sequence is something like this:
[15:55:44] <seb_kuzminsky> update debian/changelog and VERSION, commit, tag, push

[19:11:05] <cradek> someone with methodical troubleshooting skills who can reproduce this stepgen problem could use git bisect to find the commit that breaks it
[19:12:00] <cradek> seems like it has morphed from a bug "on 10.04" into "after 2.4.1 sometime when running on 8.04"
[19:12:44] <cradek> the bug is reported on 2.6.0, which doesn't exist, and I haven't seen anyone say they've made sure the configs match
[19:13:57] <cradek> ah, cmorley is on it now

[19:23:26] <jepler> 3b250c9 Merge remote branch 'origin/v2.4_branch'
[19:23:28] <jepler> 733af60 Allow the user to specify a stepping waveform
[19:23:46] <cradek> src/hal/drivers/mesa-hostmot2/stepgen.c
[19:23:55] <jepler> durrrrr
[19:24:38] <cradek> don't be too hard on yourself - I think it has been claimed that software stepgen is also broken
[19:27:25] <cradek> "and this configuration is a software stepgen and do the same (joint folloving error)."
[19:27:53] <psha> cradek: 2.6.0 means that this bug will be introduced somewhere this year?
[19:28:11] <psha> or just git master introduces it as 2.6?
[19:28:21] <cradek> 2.6.0 does not exist so I don't know what a user means when he says the bug is in 2.6.0
[19:28:26] <seb_kuzminsky> master calls itself 2.6.0-pre0
[19:29:07] <cradek> seb_kuzminsky: have you tried to reproduce this?
[19:29:27] <seb_kuzminsky> link?
[19:29:34] <seb_kuzminsky> (ie: not yet)

[22:07:05] <andypugh> Is it enough to have a #define of a header file with a function prototype in it for the file to find a function?
[22:07:24] <andypugh> Or do I need to do something cleverer with externs and such?
[22:08:55] <alex_joni> do you mean #include ?
[22:09:21] <andypugh> Err, yes.
[22:09:26] <andypugh> (Checks)
[22:09:37] <andypugh> Yes.
[22:09:53] <alex_joni> you usually include the .h, where the function prototype is defined
[22:09:58] <alex_joni> then the compiling works
[22:10:12] <andypugh> I am getting the message "hm2: Unknown symbol hm2_get_bspi"
[22:10:17] <alex_joni> but for linking you also need the .c (more specific the .o)
[22:10:21] <andypugh> It all compiles...
[22:10:56] <andypugh> hm2_get_bspi is a function in another file.
[22:12:05] <alex_joni> if it's not immediate obvious where the function is, you can name it extern, then the linker won't check so closely
[22:12:14] <alex_joni> just make sure it's available when you call it
[22:12:34] <andypugh> I get the error when I call it. There are no compiler warnings.
[22:13:39] <andypugh> A complication is that the function is being called from a comp. I might need to look at the generated C-code

[22:17:35] <andypugh> http://pastebin.com/wxjPHMGj
[22:18:27] <andypugh> hostmot.h contains the function prototype. The #include is in a slightly odd place because of the way the comp preprocessor does stuff.
[22:18:54] <andypugh> I _don't_ see the result of the HM2_PRINT statement before the call to hm2_get_bspi
[22:19:08] <alex_joni> hmm.. so how do you compile it?
[22:19:16] <andypugh> make
[22:19:27] <alex_joni> makefile?
[22:19:39] <andypugh> The normal one
[22:20:08] <alex_joni> and you added your source file?
[22:20:19] <andypugh> The comp is in the hal/components directory so gets picked up by the generic submakefile
[22:20:50] <andypugh> The get_count function runs when I addf the module.
[22:21:12] <alex_joni> getting picked up doesn't mean it gets the proper .o linked in
[22:21:20] <alex_joni> I would suspect..
[22:21:51] <andypugh> I have made lots of other comps, and they have all worked. None have called external functions though.
[22:22:07] <alex_joni> that's my point
[22:22:21] <alex_joni> I think doing this as a comp is overcomplicating things
[22:22:40] <andypugh> I am trying to prove that it can be done.
[22:23:22] <andypugh> The idea is to make making other sub-drivers for other SPI devices relatively easy
[22:23:46] <andypugh> 'course a proper programmer would be a good starting point
[22:24:33] <alex_joni> I doubt a comp would be of an advantage in this case
[22:24:58] <alex_joni> I mean who attempts to write a subdriver for hostmot surely can cope with 30 extra lines of c-code
[22:25:08] <alex_joni> (which are already there from your example btw)

[22:27:50] <andypugh> The pin definitions and handling of multiple instances is a lot tidier in a comp.
[22:28:22] <andypugh> self-documenting too.
[22:28:47] <alex_joni> then do that, rename the generated file and pickup from there :)
[22:29:23] <andypugh> Any idea how to add a comp to the makefile?
[22:30:02] <alex_joni> maybe put it someplace else, and use a similar incantation for generating the .c file, then a regular compiling/linking

[22:31:03] <cpresser> alex_joni: comp has a option "--preprocess"
[22:31:23] <cpresser> use that and make sure it is run bevore CC
[22:32:21] <andypugh> I have absolutely no idea where makefiles are concerned
[22:32:37] <seb_kuzminsky> andypugh: look at how hostmot2 exposes hm2_register() to the low-level anyio drivers
[22:35:12] <seb_kuzminsky> EXPORT_SYMBOL_GPL(hm2_register);
[22:35:15] <seb_kuzminsky> bbl
[22:35:36] <andypugh> it just appears to be declared in hm2-lowlevel.h, which is included in hostmot2.h, or am I missing something?
[22:35:53] <andypugh> Looks like I am missing something :-)
[22:37:52] <cpresser> perhaps i dont see the whole picture, but may it be possible that you have to link you file to the one conatining the function hm2_get_bspi
[22:38:21] <micges> andypugh: pastebin source, i'll try it
[22:38:40] <cpresser> ah no, take that back.. you said that tge file compiles, its a runtime error
[22:38:56] <andypugh> I think seb has it with the EXPORT_SYMBOL

[23:10:24] <jepler> for one hal component to "see" a function defined in another hal component, the component defining the function must (A) export the function with EXPORT_SYMBOL_GPL or EXPORT_SYMBOL and (B) be loaded before the component using the function.
[23:11:04] <jepler> for instance, here's one of the existing EXPORT_SYMBOL_GPL from hostmot2: hostmot2.c:EXPORT_SYMBOL_GPL(hm2_register);
[23:11:31] <jepler> this is the function that lets an individual card driver be registered
[23:11:45] <andypugh> I have them all talking to each other now. It's crashing RTAI every time, but you can't have everything. I am totally baffled by strings in C
[23:12:17] <jepler> HM2_PRINT_NO_LL is just a macro that expands to rtapi_print, which is already exported.
[23:12:48] <andypugh> Yes, I am using it to trace program flow.
[23:13:07] <andypugh> (because I have not invested the time to learn a debugger
[23:13:39] <jepler> afaik there's only an effective debugger for components that can be built with --enable-simulator, so you'd still be flying blind working on hostmot2
[23:13:45] <andypugh> I am getting very fast at typing "sudo shutdown -r now"
[23:14:49] <jepler> if you want hm2_get_bspi to change the value of b inside EXTRA_SETUP (e.g., to a new hm2_bspi_instance that hm2_get_bspi just allocated), then you have to pass &b to it, and the corresponding item in the prototype would be hm2_bspi_instance**
[23:15:34] <jepler> otherwise the pointer b in EXTRA_SETUP is never initialized before you dereference it at b->name
[23:15:36] <andypugh> I thought I had defined b as a pointer?
[23:16:13] <andypugh> I think this is one of those things that you either get straight away, or end up forever second-guessign yourself on.
[23:16:40] <jepler> Yes, the type of b is pointer to hm2_bspi_instance. But the function of hm2_bspi_instance is to change what b points at (the value of b). In C (and unlike in some other languages), when you want to change the value of something passed in, you do it by passing the location of the thing to be modified
[23:16:52] <jepler> that means you pass in &b, and that means the type of the parameter gets more stars
[23:16:57] <andypugh> Ah, yes.
[23:17:07] <andypugh> Pass-by-value catches me out again
[23:17:24] <andypugh> (I have spent years in VBA, which is always pass-by-reference)
[23:17:34] <jepler> yes, it's often difficult to shift gears like that
[23:18:14] <andypugh> VBA is OO too, so I am forever swapping object identities with each other.
[23:19:17] <andypugh> This is probably sacrelige, but I rather like VBA and the IDE in Excel. It has it's quirks, though.
[23:19:59] <andypugh> So: int hm2_get_bspi(hm2_bspi_instance_t **q, char *name){
[23:20:07] <andypugh> q = &all_bspis[i]->instance[j];
[23:20:26] <andypugh> I am guessing that that q needs a layer of indirection?
