最近安裝FormCalc
出現了一些問題 如：
./compile: 1: ./compile: : Permission denied
mkdir: 無法建立目錄‘’: 沒有此一檔案或目錄
Cannot create directory
google過很多辦法，始終無法解決，於是寄信給原作者詢問
他的回信如下：
please check that the partition on which you're installing
this software has execution enabled (see if there is e.g.
a noexec attribute in /etc/fstab).
Likewise, check that you have /bin/sh and that it's
executable.
Next, try running "sh -x ./compile" and see how far you get.
If compile stops while invoking a program (e.g. math),
run that program manually to see if there are any problems
with shared libraries. Maybe you just need to do an
ldconfig to refresh /etc/ld.so.cache.
其實我看不太懂他要我作些什麼，
我 sudo vi /etc/fstab 出現了：
# UNCONFIGURED FSTAB FOR BASE SYSTEM
/host/ubuntu/disks/swap.disk none swap sw 0 0
和網路上的例子好像很不一樣，如：

後面，我嘗試使用指令 ldconfig 似乎沒有什麼效果
不知道有沒友人有類似經驗呢？ 感謝
另外補上 sh -x ./complie 的結果：
+ CC=gcc
+ CXX=g++
+ MCC=mcc
+ CFLAGS=-O3 -fomit-frame-pointer -ffast-math -Wall -Wextra
+ dirname ./compile
+ SRC=.
+ mathcmd=math
+ exe=
+ shopt -s nullglob
+ set --
+ uname -s
+ test -z
+
PATH=/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:
which math
+ mathcmd=
+ -run Print[$SystemID]; Exit[]
./compile: 1: ./compile: : Permission denied
+ tr \r
+ tail -1
+ set --
+ test 0 -ne 1
+ DEST=
+ test -d
+ mkdir
mkdir: 無法建立目錄‘’: 沒有此一檔案或目錄
+ echo Cannot create directory
Cannot create directory
+ exit 1
