Building GTK+2.0 developement library

jiashyang — Mon, 15 Dec 2008 06:20:23 +0000

reference gtk website http://www.gtk.org/

上星期用了將近一個星期的時間，把環境建立起來，以下記錄簡單安裝過程，在安裝時有缺其它的 package 就直接用 yum 安裝上去了，當中有卡到 glib 舊版本的問題，所以用 rpm -e glib –nodeps 移除掉，但是不移除相依的 package。

OS: Fedora Core 8
main Package: GTK+ 2.14、GLib 2.18、Pango 1.20
tarball 方式安裝我都裝到 /usr/local 目錄下(defalut path)

install pixman package:
# tar -zxvf pixman-0.13.2.tar.gz
# cd pixman-0.13.2
第一種方式
# ./configure pixman_LIBS=』-L/usr/local/lib』 \
pixman_CFLAGS=』-I/usr/local/include』 \

# make LDFLAGS=』-L/usr/local/lib』 \
CFLAGS=』-I/usr/local/include/pixman-1″

# make isntall

第二種方式(pkgcofig 需再去找一下這方面的資料)
# ./configure PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig \
LD_LIBRARY_PATH=/usr/local/lib
# make; make install

install cario package:
# tar -zxvf cario-1.8.4.tar.gz
# cd cario-1.8.4
# ./configure PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig \
LD_LIBRARY_PATH=/usr/local/lib
# make; make install

install glib package:
# tar -jxvf glib-2.18.0.tar.bz2
# cd glib-2.18.0
# ./configure PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig \
LD_LIBRARY_PATH=/usr/local/lib
# make; make install

install atk package:
# tar -jxvf atk-1.25.2.tar.bz2
# cd atk-1.25.2
# ./configure PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig \
LD_LIBRARY_PATH=/usr/local/lib
# make; make install

install pango package:
# tar -jxvf pango-1.20.5.tar.bz2
# cd pango-1.20.5
# ./configure PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig \
LD_LIBRARY_PATH=/usr/local/lib
# make; make install

install tiff package:
# tar -zxvf tiff-3.8.2.tar.gz
# cd tiff-3.8.2
# ./configure PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig \
LD_LIBRARY_PATH=/usr/local/lib
# make; make install

install libjped and jasper used by yum
install xorg-x11 and x11 used by yum (ps. install all about x software development)

install gtk+ package:
# tar -jxvf gtk+-2.14.0.tar.bz2
# cd gtk+-2.14.0
# ./configure PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig \
LD_LIBRARY_PATH=/usr/local/lib
# make; make install

write sample code:
copy gtk website sample code.
how to compile? need pkg-config this tools, it can show include header and library about when you need library.
like this –> pkg-config –cflgs –libs pkg-name-xxx
因為上面我裝在 /usr/local 的目錄下，所以在編譯時我必須指定所需要的標頭檔及函式庫在哪裡，預設只會去找 /usr/lib and /usr/include
後來安裝的 pkg-config pc 檔案都在 /usr/local/lib/pkgconfig，所以我先設定PKG_CONFIG_PATH和LD_LIBRARY_PATH 路徑名稱
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export LD_LIBRARY_PATH=/usr/local/lib
compile:
gcc -o helloGTK helloGTK.c `pkg-config –cflags –libs gtk+-2.0`

shared memory of IPC

jiashyang — Thu, 02 Oct 2008 03:42:36 +0000

由 parent process fork 一個 child process, 這兩個 process communication 是透過 shared memory 的方式
sample code

posix_share_memory.c

    1 #include 
    2 #include 
    3 #include 
    4 #include 
    5 #include 
    6 #include 
    7 
    8 int main()
    9 {
   10         int segment_id = 0;
   11         char *shared_memory = NULL;
   12         const int size = 4096;
   13         pid_t child_pid = 0;
   14 
   15         /* Allocate a shared memory segment */
   16         segment_id = shmget(IPC_PRIVATE, size, S_IRUSR | S_IWUSR);
   17 
   18         /* Attach the shared memory segment */
   19         shared_memory = (char *)shmat(segment_id, NULL, 0);
   20 
   21         /* Write a message to the shared memory segment */
   22         sprintf(shared_memory, "Hi, there");
   23 
   24         child_pid = fork();
   25         if (child_pid < 0) { // fork fail
   26                 printf("fork fail !!\n");
   27                 goto exit;
   28         } else if (child_pid > 0) { // parent process running
   29                 wait(NULL);
   30                 printf("child process complete!!\n");
   31                 printf("shared_memory is : %s\n", shared_memory);
   32                 goto exit;
   33         } else { // child process running
   34                 strcat(shared_memory, "\nI'm child process");
   35                 exit(0);
   36         }
   37 
   38 exit :
   39         /* Detach the shared memory segment */
   40         shmdt(shared_memory);
   41 
   42         /* Remove the shared memory segment */
   43         shmctl(segment_id, IPC_RMID, NULL);
   44 
   45         return 0;
   46 }// end of main

install ie for ubuntu

jiashyang — Wed, 25 Jun 2008 06:00:43 +0000

主要是參考下面這個 blog

http://blog.pixnet.net/Nelson/post/12146305

安裝起來的 ie 怪怪的, 像檢索時無法輸入中文字, 啟動了 ie 後, 我的電腦硬碟燈一直閃不停, 效能變的好慢, 關掉 ie 也一樣
有幾次還當掉~~~|||
先記錄起來, 有空再裝一次看看

Debian packages

jiashyang — Tue, 24 Jun 2008 01:51:30 +0000

To install a .deb file, double click on it and then select InstallPackage
Another choese, open terminal window and typeing: sudo dpkg -i PackageFile.deb
To uninstall, run package manager or in terminal window typeing: sudo dpkg -r PackageName

Ubuntu 常用套件名稱(筆記)

jiashyang — Mon, 23 Jun 2008 06:16:15 +0000

Flash Player plug-in firefox
sudo apt-get install flashplugin-nonfree

Eclipse
sudo apt-get install eclipse

JAVA JDK
sudo apt-get install sun-java5-jdk

中文輸入法
sudo apt-get install gcin

aMSN
昨天搞了一天,還是沒完全弄好,今天早上乾脆刪掉重新用套件管理方式來安裝好了(安裝前先移除舊版)

手動：1. 先安裝 tcl & tk   web site --> http://tcl.sourceforge.net/
     2. 再安裝 aMSN web site --> http://www.amsn-project.net/
     3. 過程不詳述(因為失敗), 完成後執行 aMSN 依照畫面指示安裝 TLS(第一次執行),
        在這裡卡了很久尚未成功

自動：1. sudo apt-get install tcl tk amsn tcltls
     2. 執行成功, 但......無法輸入中文(還在survey...|||)
繼無法輸入中文後, 無意間上網找 scim 與 gcin 有什麼不一樣, 間接執行切換輸入法指令後,
居然可以輸入中文了, 但我覺得是碰巧的, 不過還是記錄一下吧, 下面為使用 im-switch 切換輸入法

scim
   sudo im-switch -s scim
gcin
   sudo im-switch -s gcin

GnomeBaker 燒錄軟體 for gnome
sudo apt-get install gnomebaker

徬徨

jiashyang — Wed, 21 May 2008 06:50:30 +0000

最近心情感到有點沮喪，有點煩，好累，在這個行業我只能孤軍奮戰(誰叫我自己想走這一條路 |||)
好想好好的休息一段時間，走的真的有點累了，不知道現在到底要走去哪？

有時候連話都不太想講了，只想一個人靜靜的…….(也不知道該發呆還是做其它事)
