編譯 Android OpenCV on Ubuntu 11.04

我的Ubuntu的版本是10.04

不過我決定還是試看看

在安裝的部份我下載這三個東西

CMake 2.8.8

SWIG 2.0.5

Apache-Ant 1.8.3

CMake要下載Source distributions這個版本的

載到Binary會沒有configure安裝指令在

接著按照教學步驟一個一個指令去執行

解壓縮：tar –zxvf cmake-2.8.8.tar.gz

cd cmake-2.8.8

./configure –prefix="/opt/tools/cmake-2.8.8"

(上面這個步驟我會發生錯誤，有可能是指令錯誤也有可能是沒有安裝到什麼東西

我的錯誤訊息是

Error when bootstrapping CMake:
Cannot find appropriate C++ compiler on this system.
Please specify one using environment variable CXX.
See cmake_bootstrap.log for compilers attempted.

How to set C++ environment variable in Linux ubuntu?

我在上面這個網站找到解決辦法，是說系統沒有C++跟gcc，所以必須安裝那些東西才能再安裝cmake

sudo apt-get install build-essential

/configure --prefix="/opt/tools/cmake-2.8.8"

make

sudo make install

即可成功安裝)

SWIG下載swig-2.0.5.tar.gz

tar –zxvf swig-2.0.4.tar.gz

cd swig-2.0.5

./configure --prefix="/opt/tools/swig-2.0.5"

(然後這裡又發生錯誤，我的錯誤訊息是

configure: error: 
 Cannot find pcre-config script from PCRE
 (Perl Compatible Regular Expressions)

 library package. This dependency is 
needed for configure to complete,
Either:
 - Install the PCRE developer package
 on your system (preferred approach).
 - Download the PCRE source tarball
, build and install on your system
 as you would for any package 
built from source distribution.
 - Use the Tools/pcre-build.sh script
 to build PCRE just for SWIG to statically
 link against. Run 'Tools/pcre-build.sh --help'
 for instructions.
 (quite easy and does not require privileges 
to install PCRE on your system)
 - Use configure --without-pcre to disable
 regular expressions support in SWIG
 (not recommended).
