errors compiling Gem on ubuntu

Hi list, I'm trying to compile Gem from CVS but I get errors on pix_deinterlace ubuntu 2.6.12-10-386 (I followed the readme in src as much as possible but: freeglut3-dev was needed libtiff3g-dev is obsolete libgl-dev is obsolete) here is the error: pix_deinterlace. cpp:111: error: no ‘void pix_deinterlace::processYUVAltivec (imageStruct&)’ member function declared in class ‘pix_deinterlace’ pix_deinterlace.cpp: In member function ‘void pix_deinterlace:: processYUVAltivec(imageStruct&)’: pix_deinterlace.cpp:116: error: ISO C++ forbids declaration of ‘vector’ with no type pix_deinterlace.cpp: 116: error: expected ‘;’ before ‘unsigned’ pix_deinterlace.cpp:120: error: ‘vector’ was not declared in this scope pix_deinterlace.cpp:120: error: expected `;' before ‘unsigned’ pix_deinterlace.cpp:121: error: expected `;' before ‘bool’ pix_deinterlace.cpp:123: error: expected `;' before ‘unsigned’ pix_deinterlace.cpp:131: error: ‘temp1’ was not declared in this scope pix_deinterlace.cpp:131: error: ‘vec_splat_u8’ was not declared in this scope pix_deinterlace.cpp:134: error: ‘thresh’ was not declared in this scope pix_deinterlace.cpp:134: error: ‘union pix_deinterlace::processYUVAltivec(imageStruct&)::<anonymous>’ has no member named ‘v’ pix_deinterlace.cpp:135: error: ‘vec_splat’ was not declared in this scope pix_deinterlace.cpp:143: error: ‘pixels’ was not declared in this scope pix_deinterlace.cpp:143: error: ‘vec_avg’ was not declared in this scope pix_deinterlace.cpp:165: error: ‘temp2’ was not declared in this scope pix_deinterlace.cpp:165: error: ‘pixels’ was not declared in this scope pix_deinterlace.cpp:165: error: ‘vec_subs’ was not declared in this scope pix_deinterlace.cpp:167: error: ‘temp3’ was not declared in this scope pix_deinterlace.cpp:171: error: ‘mask’ was not declared in this scope pix_deinterlace.cpp:171: error: ‘vec_cmpgt’ was not declared in this scope pix_deinterlace.cpp:172: error: ‘mask2’ was not declared in this scope pix_deinterlace.cpp:174: error: ‘vec_or’ was not declared in this scope pix_deinterlace.cpp:178: error: ‘vec_avg’ was not declared in this scope pix_deinterlace.cpp: 182: error: expected `)' before ‘unsigned’ pix_deinterlace.cpp:182: error: expected `)' before ‘;’ token make[1]: *** [pix_deinterlace.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make[1]: Leaving directory `/home/davide/CVS-GEM/Gem/src/Pixes' make: *** [Pixes] Error 2 this is the first time I try to compile Gem on linux so I might be missing something obvious.. ciao, davide.

The 'auto' message is probably in wider use, so I am more inclined to have that one be the 'real' message. 'rate' can be kept for backwards compatibility. This way an 'auto 1' will still play movies at the default rate of the file. I think the original problem you are having with auto for pause is actually a bug which is now fixed. > Indeed the feature is really handy, especially for this installation, > which plays 16 videos simultaneously.

At least 6 of those come off of disk. > Say any info on the installation you've been talking about using pix_record? There are several installations spread from Hong Kong to San Diego to Madrid. It's probably up to thousands of hours of testing for the core objects like pix_film, pix_video and pix_record as well as some of the pix_ processing code and fragment shaders. They are slated to run for up to eight years. Jamie has some Mac Minis set up in a long term (permanent?) installation with kids torture testing them in Louisville. cgc

again pix_film problem on OSX
by B. Bogart 07 Feb '06

07 Feb '06

Hey all, Druging up this old thread. I'm using gem 0.90 on OSX and I noticed that when we send the "auto 0" message the video does pause (as normal), but when I send the "auto 1" message, I expect the video will unpause and continue playing from the last frame it was on. Problem is it seems "auto 1" jumps to the first frame and then continues playing... I just want "auto" to be the same as "pause" that starts and stops the internet counter. Also I'm depending on the feature of QT playing the sound in sync when using the "auto" message. Any quick fixes would be appreciated as I need this for a demo next week! Thanks ..b.

pix_contrast and pix_deinterlace
by chris clepper 06 Feb '06

06 Feb '06

Added these objects that were lying around: pix_contrast (also known as pix_saturation) adjusts contrast and saturation pix_deinterlace does basic field averaging and a type of 'adaptive' blending based on motion difference (using the non-discriptive 'mode 0/1' message). Both of these are YUV only right now, but I will write the RGB version on Windows pretty soon. cgc

Gem window won't 'destroy'
by Jamie Bullock 06 Feb '06

06 Feb '06

Another question. I've successfully compiled Gem using ./configure --disable-ARB --disable-NV, and linking against the ati proprietary libGL. Everything seems to work very nicely. Only thing is sending a 'destroy' message to [gemwin] crashes the gemwin. When I say 'crashes', I mean that PD is still useable, but the gemwin freezes, and can't be closed without restarting the window manager (Enlightenment DR16). Any ideas? Jamie

GemPBuffer & CGLPBufferObj
by IOhannes m zmoelnig 06 Feb '06

06 Feb '06

hi. compiling the current Gem-CVS on OSX fails on my machine (osX 10.3.9), because CGLPBufferObj (and the like) is not in the headers. in my OpenGL.h i only find CGL_VERSION_1_0 which CGL_VERSION is needed for CGLPBufferObj? mfg.as.dr IOhannes

[pix_record] api question
by IOhannes m zmoelnig 06 Feb '06

06 Feb '06

i am currently not really happy with the interfacing of [pix_record]. basically it has been taken from [pix_write], which was meant for single-frames and not for movies. what i like least is that there are "bang" (for single frames) "auto 1/0" (for a series of frames) and "record 1/0" for turning recording on/off. the bad thing is, that while splitting this object into several i have eventually lost the "record" message and now i am missing it :-( however, i am wondering whether we really need the "auto" and "bang" ways of recording. if somebody really wants to do a "stop-motion" video they can well do so via turning the rendering on/off for the whole (sub)tree where [pix_record] lives. i am thinking of making [pix_record] close to [writesf~], e.g it only takes an "open"-message to specify the filename, and a "start"/"stop" (or 1/0) pair to start and finish(!) recording. does this sound bad? will it break patches? mfg.a.arsdr IOhannes

Gem CVS build failure - FTGL
by Jamie Bullock 06 Feb '06

Hi IOhannes, I'm having a stab at getting Gem working on my Gentoo box, and have got stuck with FTGL font support. The build fails as follows: TextBase.cpp: In member function `virtual void TextBase::render(GemState*)': TextBase.cpp:67: error: 'class FTFont' has no member named 'BBox' TextBase.cpp:73: error: 'class FTFont' has no member named 'Render' TextBase.cpp: In member function `virtual void TextBase::setFontSize(t_float)': TextBase.cpp:85: error: 'class FTFont' has no member named 'FaceSize' TextBase.cpp: In member function `virtual void TextBase::fontNameMess(const char*)': TextBase.cpp:132: error: 'class FTFont' has no member named 'Depth' TextBase.cpp: In member function `virtual void TextBase::justifyFont(float, float, float, float, float, float, float)': TextBase.cpp:294: error: 'class FTFont' has no member named 'Ascender' make[1]: *** [TextBase.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make[1]: Leaving directory `/usr/local/src/CVS/Gem/src/Base' make: *** [Base] Error 2 I have FTGL 2.1.2 installed. Gem latest from CVS. Jamie
