Ubuntu中源碼編譯Virtualbox

環境： Ubuntu 12.04 (64 bits)， Virtualbox 4.2.8源碼

首先從https://www.virtualbox.org/wiki/Downloads下載Virtualbox原始碼，其官方Wiki上還提供了編譯指導：https://www.virtualbox.org/wiki/Linux%20build%20instructions。總體上按指導上一步步來就行，但實際操作中總還是會碰到問題的，下面總結一下：

1. 指導中提到要建立libXTrap.so的軟連結，但Ubuntu中壓根沒有這個檔案。根據https://forums.virtualbox.org/viewtopic.php?f=10&t=52734，不用去管它。

2. /home/zjin/source/VirtualBox-4.2.8/src/bldprogs/checkUndefined.sh: following symbols not defined in the files
xxx：
__realpath_chk __memcpy_chk __sprintf_chk

根據https://forums.virtualbox.org/viewtopic.php?f=10&t=54337，建立LocalConfig.kmk，內容為

VBOX_JAVA_HOME := /usr/lib/jvm/java-6-openjdkVBOX_WITH_WARNINGS_AS_ERRORS :=VBOX_WITH_TESTCASES :=VBOX_WITH_TESTSUITE := 

3. jni.h: No such file or directory

LocalConfig.kmk中JDK路徑沒設好，確保VBOX_JAVA_HOME路徑下有include/jni.h。

4. 編譯tex檔案時出錯：

! I can't find file `bchr8t'.
<*> ...:=ljfour; mag:=1; nonstopmode; input bchr8t
                                                  
Please type another input file name
! Emergency stop.
<*> ...:=ljfour; mag:=1; nonstopmode; input bchr8t

根據http://michail.flouris.net/2010/07/using-the-tkiz-package-in-latex-on-rhel5-centos-fc-and-ubuntu-linux/，

$ sudo apt-get install texlive-fonts-recommended

即可解決。
