Qt4.7.1编译pc版本的时候：collect2:ld terminated with signal 9(或11)
转载：http://hi.baidu.com/seaeechou/blog/item/cbc860210fd9bf489822edd3.html
当时内存几乎用完了，发生这个错误是因为内存不够，编译不过来。系统是ubuntu 11.04， 2G的物理内存不够，swap分区是1G。
CXXLD libwebkitgtk-1.0.la
collect2: ld terminated with signal 9 [Killed]
make[1]: *** [libwebkitgtk-1.0.la] Error 1
make[1]: Leaving directory `/home/cselken/Downloads/webkit/WebKitBuild/Debug'
make: *** [all] Error 2
Failed to build WebKit using 'make'!
解决方法是增大交换分区的大小。

Four-step Process to Add Swap File
1 Creating a file the size you want.
2 Formatting that file to create a swapping device.
3 Adding the swap to the running system.
4 Making the change permanent.
For Adding a 512 MB swap examp
1 Creating a file for 512 MB size you want:
We will create a /mnt/512Mb.swap swap file and set the permissions so that users cannot read it directly.
sudo fallocate -l 512m /mnt/512Mb.swap sudo chmod 600 /mnt/512Mb.swapfallocate length suffixes are: k, m, g, t, p, e (See man fallocate).
By default your swap file may be created world readable. We set the 600 mode permissions in order to prevent users from being able to read potentially sensitive information from the swap file.
2 Formatting that file to create a swapping device:
sudo mkswap /mnt/512Mb.swap
3 Adding the swap to the running system:
sudo swapon /mnt/512Mb.swap
The additional swap is now available and can be seen by "cat /proc/meminfo"
4 Making the change permanent:
Edit the /etc/fstab:
gksudo gedit /etc/fstabAdd this line at the end of the file:
/mnt/512Mb.swap none swap sw 0 0
Save. After the next reboot the swap will be used automatically.
Example of making a swap file
This is an example of making and using a swap file on a computer with no swap partition.
user@computer:~$ sudo fallocate -l 512m /mnt/512Mb.swapPassword:
user@computer:~$ sudo mkswap /mnt/512Mb.swap
Setting up swapspace version 1, size = 536866 kB no label, UUID=dd6a01c8-93f0-41e0-9b7a-306956d8821b
