PowerPC Altivec Linux SVN build broken

[anonymous]

Hey all, PowerPC Linux (Ubuntu 7.04 PPC) build appears to be broken, not sure why.

Hope this is a simple fix, feel free to mail/msg me if there's anything I can help with.

Thanks.

Could you maybe provide the preprocessor output of this source file?

cd libs/libmythtv

preprocessor for yuv2rgb.cpp

[anonymous]

Hello,

I'm facing the same problem trying to compile mythtv on Macmini PPC.

I have attached the requested preprocessor file for the cpp file yuv2rgb

[Nigel]

Just did a successful test build then on my G4. No errors. Note that a MacMini? build will have different arguments (if it is running OS X):

hello nigel,

the latest svn compiles with no problems on my macbook OSX 10.4 . but my mac linux/ppc/gentoo is throwing the same error as my freind in who issued the ticket. the compiler complains about type conversion. FYI, I have tried hardcoding the boolian "any_extra" to both true and false. both compilation trail were successful. however mythtv fails when entering LiveTV/playingVideo/WatchRecordings.

any hints??

[anonymous]

Thanks for the clarification. Looks like I need to download and install a PPC linux distro.

[Nigel]

OK. Have installed 7.04 on my PB G4 400, did a few apt-get installs, and am now building mythtv src. I get a similar error:

(In [14493]) Workaround GCC 4.1.2 bug(?) where bool is preprocessed into something strange: attribute((altivec(bool))) unsigned which neither I or the compiler can understand :-) See #3946 Also simplified the boolean stride/extra checking. (u_extra and v_extra are either both zero, or not)

[Nigel]

The pre-processor was mangling the bool type somehow. Easiest fix was to remove it.
A clean build with the latest source (and that fix) worked for me. Bander, if you are still having problems after a "make distclean; ./configure; make" then try a debug build, and please create a new Trac ticker with the gdb output
