thanks hans for this indication this is the correct flag to compile it with v4l2?! --with-libv4l2-includes=/usr/lib/libv4l2.so
hmm, the ..-includes flag is meant for adding _include_ directives to the compiler rather than libraries for the linker.
try something like "--with-libv4l" and/or "--with-libv4l2" and you should be done if libv4l is properly installed.
the package builts but still i'm gettin error: [pix_video]: could not find a backend for driver 'v4l2'
i also tried a gem solo & make spits this error: recordQT4L.cpp -o ../Objects/recordQT4L.o recordQT4L.cpp: In function ‘lqt_file_type_t guess_qtformat(const char*)’: recordQT4L.cpp:96: error: invalid conversion from ‘const char*’ to ‘char*’ make[1]: *** [recordQT4L.o] Error 1 make[1]: Leaving directory `/home/olsen/pd/pd-extended/Gem/src/Pixes' make: *** [Pixes] Er
yah, this is dues to an overly pedantic compiler (or probably: invalid headers: the line the error is referring to is (here; but i might have a different version :-)) using the (const char*) argument to guess_qtformat() as input for strchr(). according to my man-pages, strchr() indeed takes (const char*) rather than (char*). if this is indeed the problem, just add a cast to (const char*) to the call of strchr(), and file a bug-report to ubuntu that they are shipping broken headers)
same with gem 0.92-1 recordQT4L.cpp: In function ‘lqt_file_type_t guess_qtformat(const char*)’: recordQT4L.cpp:96: error: invalid conversion from ‘const char*’ to ‘char*’ make[1]: *** [recordQT4L.o] Error 1 make[1]: Leaving directory `/home/olsen/pd/extra/0.92-1/Gem/src/Pixes' make: *** [Pixes] Error 2
with gem0.92svn i stuck at the configure: ./configure: line 3005: syntax error near unexpected token
PIC,' ./configure: line 3005:
GEM_ARG_ENABLE(PIC, PositionIndependentCode (potentially slower))'
you did run ./autogen.sh, did you?
