第一個問題是make.conf裡的最佳化設定，我的是p4 800 ht 我只設了CPUTYPE=p4，這就可以了嗎? 是否還須要其他的設定才能編譯軟體時達到 最佳化。或者有其他詳細的中文說明可以參考。 第二個問題，我編譯xorg6.8.1時出現錯誤，好像我在編譯其他軟體都有不同的錯 誤發生，就算我用光碟中的ports_tree來編譯也是有錯誤，只是錯誤訊息不同而 已。以下是我編譯xorg6.8.1時的錯誤訊息，不知道是程式本身的錯誤還是我機器 的問題： ===> Installing for xorg-6.8.1 ===> xorg-6.8.1 depends on executable: xvinfo - not found ===> Verifying install for xvinfo in /usr/ports/x11/xorg-clients ===> Building for xorg-clients-6.8.1_1 making all in programs/appres... making all in programs/bdftopcf... making all in programs/bitmap... making all in programs/beforelight... making all in programs/editres... making all in programs/fslsfonts... making all in programs/fstobdf... making all in programs/iceauth... making all in programs/ico... making all in programs/listres... making all in programs/luit... making all in programs/makepsres... making all in programs/dpsinfo... making all in programs/dpsexec... making all in programs/texteroids... making all in programs/mkcfm... making all in programs/mkfontdir... making all in programs/mkfontscale... making all in programs/oclock... making all in programs/proxymngr... making all in programs/rgb... making all in programs/rstart... making all in programs/showfont... making all in programs/smproxy... making all in programs/twm... making all in programs/viewres... making all in programs/x11perf... cc -O -pipe -march=pentium4 -ansi -pedantic -Wno-system-headers -Dasm=__asm -Wall -Wpointer-arith -Wundef -I/usr/ports/x11/xorg-clients/work/xc -I/usr/ports/x11/xorg-clients/work/xc/exports/include -I/usr/X11R6/include -I/usr/local/include -I/usr/local/include/freetype2 -I/usr/local/include/freetype2/config -I/usr/ports/x11/xorg-clients/work/xc/exports/include/X11 -I/usr/ports/x11/xorg-clients/work/xc -I/usr/ports/x11/xorg-clients/work/xc/exports/include -I/usr/X11R6/include -DCSRG_BASED -DFUNCPROTO=15 -DNARROWPROTO -DMITSHM -DXFT -DXFREE86_FT2 -DXRENDER -c do_traps.c do_traps.c:113: error: syntax error before '*' token do_traps.c:113: warning: type defaults to `int' in declaration of `traps' do_traps.c:113: error: ISO C forbids data definition with no type or storage class do_traps.c: In function `InitFixedTraps': do_traps.c:130: error: `XTrap' undeclared (first use in this function) do_traps.c:130: error: (Each undeclared identifier is reported only once do_traps.c:130: error: for each function it appears in.) do_traps.c:130: error: `curTrap' undeclared (first use in this function) do_traps.c:131: warning: ISO C90 forbids mixed declarations and code do_traps.c:145: error: syntax error before ')' token do_traps.c:129: warning: unused variable `left' do_traps.c:129: warning: unused variable `right' do_traps.c:129: warning: unused variable `top' do_traps.c:129: warning: unused variable `bot' do_traps.c: In function `DoFixedTraps': do_traps.c:249: warning: implicit declaration of function `XRenderAddTraps' do_traps.c: In function `InitFixedTraps': do_traps.c:208: warning: value computed is not used *** Error code 1 Stop in /usr/ports/x11/xorg-clients/work/xc/programs/x11perf. *** Error code 1 Stop in /usr/ports/x11/xorg-clients/work/xc/programs. *** Error code 1 Stop in /usr/ports/x11/xorg-clients. *** Error code 1 Stop in /usr/ports/x11/xorg.
