Hello, I'm attempting to get avview installed and working but am stuck when running "make". I've downloaded different "tags" via CVS and get the same errors. The autoconf and configure seem to work OK. I'm running Debian(sid), kernel=2.4.13 All the *.c files give the following errors about tcl.h and tk.h tcl.h: No such file or directory tk.h: No such file or directory I have tcl8.3, tcl8.3-dev, tk8.3, and tk8.3-dev loaded and tcl.h and tk.h exist in /usr/include/tcl8.3/ Here is the make command and a sampling of output (I didn't include everything as it quite large): debian02:~/DOWNLOADS/CVS-UPDATES/ati_xv/avview# make gcc -pipe -g -O2 -I/usr/X11R6/include -I/root/DOWNLOADS/ffmpeg-0.4.5/ffmpeg//libav -I/root/DOWNLOADS/ffmpeg-0.4.5/ffmpeg//libavcodec xv.c frequencies.c xmisc.c string_cache.c v4l.c formats.c ffmpeg.c -ltcl8.3 -ltk8.3 -lm -ldl -lSM -lICE -L/usr/X11R6/lib -lX11 -lXext -lXv -L/root/DOWNLOADS/ffmpeg-0.4.5/ffmpeg//libav -L/root/DOWNLOADS/ffmpeg-0.4.5/ffmpeg//libavcodec -lav -lavcodec -lpthread main.c -o avview xv.c:21: tcl.h: No such file or directory xv.c:22: tk.h: No such file or directory xv.c: In function `xv_notify_handler': xv.c:26: `stderr' undeclared (first use in this function) xv.c:26: (Each undeclared identifier is reported only once xv.c:26: for each function it appears in.) xv.c: At top level: xv.c:29: parse error before `client_data' xv.c: In function `xv_numadaptors': xv.c:31: `Tk_Window' undeclared (first use in this function) xv.c:31: parse error before `tkwin' <snip> frequencies.c:12: tcl.h: No such file or directory frequencies.c:13: tk.h: No such file or directory In file included from frequencies.c:15: frequencies.h:124: parse error before `*' frequencies.c:984: parse error before `client_data' frequencies.c: In function `freq_get_table_list': frequencies.c:986: `Tcl_Obj' undeclared (first use in this function) frequencies.c:986: (Each undeclared identifier is reported only once frequencies.c:986: for each function it appears in.) frequencies.c:986: `ans' undeclared (first use in this function) frequencies.c:987: parse error before `int' frequencies.c:989: `interp' undeclared (first use in this function) frequencies.c:992: `i' undeclared (first use in this function) frequencies.c: At top level: frequencies.c:999: parse error before `client_data' frequencies.c: In function `freq_get_channel_list': <snip> xmisc.c:21: tcl.h: No such file or directory xmisc.c:22: tk.h: No such file or directory xmisc.c:24: parse error before `client_data' xmisc.c: In function `xmisc_getscreensaver': xmisc.c:26: `Tk_Window' undeclared (first use in this function) xmisc.c:26: (Each undeclared identifier is reported only once xmisc.c:26: for each function it appears in.) xmisc.c:26: parse error before `tkwin' xmisc.c:30: `Tcl_Obj' undeclared (first use in this function) xmisc.c:30: `ans' undeclared (first use in this function) xmisc.c:31: parse error before `dpms_standby' <snip> main.c:13: tcl.h: No such file or directory main.c:14: tk.h: No such file or directory In file included from main.c:16: frequencies.h:124: parse error before `*' In file included from main.c:17: xv.h:12: parse error before `*' In file included from main.c:18: xmisc.h:12: parse error before `*' In file included from main.c:19: v4l.h:31: parse error before `*' In file included from main.c:20: ffmpeg.h:12: parse error before `*' main.c:36: parse error before `*' main.c: In function `Tcl_AppInit': main.c:38: `TCL_OK' undeclared (first use in this function) main.c:38: (Each undeclared identifier is reported only once main.c:38: for each function it appears in.) main.c:40: `interp' undeclared (first use in this function) main.c:41: `TCL_ERROR' undeclared (first use in this function) make: *** [avview] Error 1 Thanks for any help. kent
