you have to use a newer version of cygwin with a gcc-3.x compiler. Threading should work then

ok, got that now and can compile.

but how would I start a pd app with a cygwin compiled object? i always get errors that it cant find the cygwin1.dll

and, is it at all possible to build standalone objects that arent dependent on cygwin1.dll? with -mno-cygwin?

i tried compiling flext with -mno-cygwin, but no dice.

Oh, I didn't see yet, that you also provide Cygwin-configs (I didn't have time to look). So this means, that with a recent Cygwin (or also MinGW?) I can build flext and flext-ernals on Windows without needing to buy an expensive MS-product that's not included in W2000?

well, I'm finding out its not that easy. At least for a windoze newbie like myself. I can compile my external and run it with cygwin. But, it only works inside the cygwin environment and is dependant on the cygwin1.dll

I've been trying to compile flext and my ext with -mno-cygwin (which should in theory compile things that run without cygwin)...but it is prooving to be pretty tough.

I'll have to take a deeper look, because maybe then I can provide W32-versions of my externals in the future myself ;)

It would be cool to have a little tutorial on how to make W32 and OS-X ready to compile externals (flext and others), btw. Linux comes with the needed tools built in.

only difference i notice so far is that one has to link with -lpd under win.

Thomas,

I have successfully compiled flext, libsamplerate and libmad under cygwin with mingw and pthreads. its a mess but it works and loads in pd under windows.

the problem im having now is that i can load my external, and see that it is registered by pd. i can even see that the thread is running properly. just whenever I turn on the dsp in pd, pd crashes.

you have any idea what this could be?

attached is the makefile im using. I have no idea how to properly link under windows with .dlls and .libs

thanks - august.

PS: there were some probs with mingw under cygwin with flext...but only with fltimer.cpp. you need to include winsock.h and do some other things. you also need to define an OS. under cygwin, i just used linux -DFLEXT_OS=3

That's great. Did flext compile without changes? Any compiler warnings?

no, since its a cygwin environment and mingw-gcc compiler that takes only the includes and libs from is mingw directory, i had to do a number of things where FLEXT_OS=3:

for timeval, i needed to add winsock.h
to skipove gettimeofday (which isnt with mingw) i had to reverse

the #if statements so that LINUX was WIN. for usleep, i had to do the same.

then in cygwin makefile, I had to add -DFLEXT_OS=3 in all CFLAGS. if you dont define an _OS, make spits out errors.

not sure how it would be best to integrate this. maybe a FLEXT_OS_CYGWINMINGW or something like that.

-august.

Hi Frank, for the Windows platform the free Cygwin and Borland compilers are supported. I don't recommend Borland since the make file format is primitive and it doesn't support threading either. A recent cygwin package should do it just well. Concerning the cygwin1.dll thing.... i also don't know if there are static libraries to link against for standalone externals.

best greetings, Thomas

I cannot login as anonymous on the sf cvs server. Is it something fixed in the cvs version?

what gcc version are you using? gcc 3.2 if prefered.

sort of looks like a flext problem. can you load other externals with flext?

Yes, it's a problem inside flext, but it's hard to believe that the respective lines of code can segfault. It would be interesting to know if other users of readanysf~ or other threaded flext externals have a similar problem. As i haven't had such problems it's probably a memory-corrupting bug somewhere else in the external. I'll have a look at it as soon as i have the time to.

best greetings, Thomas

I'm testing late, but absolutely no problems with readany here. Wonderful external and seems to be more useful for DJ applications than controlling alsaplayer remotely.

Usability-wise I guess, I would like to have "pause 1/0" messages, so that it's easier to use the pause function like on a Technics mk1200: Press to pause, press again to unpause. Otherwise a great external but I said that, didn't I?

andI might add playing backwards and some sort of interpolation would be nice (or did I miss something)

Maybe it would be solved with interpolation, but something very important for DJing is nudging i.e. pushing the track a short time for- or backward (around 5-10 msec) to align the tempo of two tracks. This currently results in clicks, at least the way I built it. Also this might be easier to build, if there was a pcm_samples output.

Just my 2 cent wishlist.

i was also thinking about a play 1 and play 0. but, one could also build this in pd. probably will be in the next release.

ill look into this though. maybe its not so difficult.

in principal it would be the same as pausing for x milliseconds eh? or doing a pcmseek +64 without flushing the internal buffer.

CK:

andI might add playing backwards and some sort of interpolation would be nice (or did I miss something)

because of the buffering, playing backwards is a bit difficult. but not impossible. with mp3 its a bit tricky cause it takes a lot of recources to be sample accurate with seeking. again, not impossible though.

and, what exactly do you mean by interpolation? example code?

Maurizio :

If you don't compile something in (for example streaming mp3 support) and you try to use that, it causes segfault.

ok, that must be a bug. ill look into it when I get back to vienna

tim:

I get glitches when speeding up readanysf~ playback. Slowing down is great. Does speeding up work smoothly for anyone else?

could be problem with the slider. the threshold from (1 - 12) is much greater on the vslider than from 1-.2 for example. you might try building a slider that is larger for the areas between .2 - 1 clicking might also happen if the file cant be read fast enough.

needless to say, you'll run into problemw speeding up streams from the net.

looking into it all

thanks for the feedback. that helps! - august.

Hi Yves, i can't reproduce the error since i don't have gcc 2.96. I never had a problem with 2.95.3, though. However, i recommend upgrading to a 3.2 version anyhow since older gccs seem to have many bugs concerning c++.

Also, methinks that you're not using an up-to-date flext, right?

best greetings, Thomas

does anyone have a flext already compiled for windows with msvc?
