How to compile the g++ object file with gcc

Here is an example shows how to compiler a program with gcc with objects files which are compiled by g++

Example codes:
( Reference from here )

test.c　
　#include
　#include
　#include "adio.h"
　#include "adstring.h"
　int main()
　{
　　char input[21];
　　char buffer[11];
　　char buf[11];
　　const char* str = "hello world!!";
　　adstring_strcpy(buffer, str, 11);
　　puts(buffer);
　　adio_fgets(input, 21, stdin);
　　puts(input);
　　adstring_strcpy(buffer, input, 5);
　　puts(buffer);
　　int a = 12345;
　　puts(adstring_itoa(buf, a, 11));
　　puts(buf);
　　return 0;
　}

adio.h
　#ifndef ADVENCE_IO_H
　#define ADVENCE_IO_H
　#include
　char* adio_fgets(char* buf, int num, FILE* fp);
　void adio_stdinclean(void);
　#endif

adstring.h
　#ifndef ADVENCE_STRING_H
　#define ADVENCE_STRING_H
　char* adstring_strcpy(char* to, const char* from, int num);
　char* adstring_itoa(char* to, int from, int num);
　#endif

adio.c
　#include
　#include
　char* adio_gets(char* buf, int num, FILE* fp)
　{
　　char* find = 0;
　　fgets(buf, num, stdin);
　　if ((find = strrchr(buf, '\n')))
　　{
　　　*find = '\0′;
　　}
　　else
　　{
　　　while (fgetc(fp) != '\n');
　　}
　　return buf;
　}
　void adio_stdinclean()
　{
　　while (getchar() != '\n');
　}

adstring.c
　#include
　#include
　char* adstring_strcpy(char* to, const char* from, int num)
　{
　　int size = num-1;
　　strncpy(to, from, size);
　　if (strlen(from) >= size)
　　{
　　　to[size] = '\0′;
　　}
　　return to;
　}
　char* adstring_itoa(char* to, int from, int num)
　{
　　char tmp[11];
　　sprintf(tmp, "%d", from);
　　adstring_strcpy(to, tmp, num);
　　return to;
　}



Make static library , here we assume object files need to be compiler in g++
　g++ adio.c adstring.c -Wall -c (this line will come out with adio.o adstring.o)
　ar rcs libadlib.a adio.o adstring.o (archieve into libadlib.a file)

　gcc test.c -I. -L. -ladlib -o test

Here, there are some errors say that the function with object files is not found.
The reason is that compiler will change c++'s function name while compiling.
In order to tell compiler not to change function name, we can use extern "C"

We can modify adio.c adstring.c into :

adio.c
　#include
　#include

　#ifdef __cplusplus
　extern "C" {
　#endif

　char* adio_gets(char* buf, int num, FILE* fp)
　{
　　char* find = 0;
　　fgets(buf, num, stdin);
　　if ((find = strrchr(buf, '\n')))
　　{
　　　*find = '\0′;
　　 }
　　else
　　{
　　　while (fgetc(fp) != '\n');
　　}
　　return buf;
　}
　void adio_stdinclean()
　 {
　　while (getchar() != '\n');
　}

　#ifdef __cplusplus
　}
　#endif

adstring.c
　#include
　#include

　#ifdef __cplusplus
　extern "C" {
　#endif

　char* adstring_strcpy(char* to, const char* from, int num)
　{
　　int size = num-1;
　　strncpy(to, from, size);
　　if (strlen(from) >= size)
　　{
　　　to[size] = '\0′;
　　} 　　return to;
　}
　char* adstring_itoa(char* to, int from, int num)
　{
　　char tmp[11];
　　sprintf(tmp, "%d", from);
　　adstring_strcpy(to, tmp, num);
　　return to;
　}


　#ifdef __cplusplus
　}
　#endif

How to connect to wireless AP in text mode

INTERFACE_NAME: your wireless interface name, you can find it by "wconfig" command
AP_NAME : the ap you want to connect
AP_PASSWARD: the key for the AP_NAME

[root@localhost ~]# iwconfig INTERFACE_NAME essid "AP_NAME" key "AP_PASSWARD"

if the IP is accessed by DHCP
[root@localhost ~]# dhclient INTERFACE_NAME

GdkFont usage

To use GdkFont, you must specify the font name
And it must specify by a XLFD describing

The simplest way is set "-*-*-medium-r-normal--N-*-*-*-p-*-*-1"
N = the font size

mase simplescalar make error

There are two possible errors due to newer version of gcc.

1. /lib64/libc.so.6: could not read symbols: Bad value
( if the system is 32-bit, error might be /lib/libc.so.6: could not read symbols: Bad value )
　　mark all "extern int errno;" ( eval.c misc.c range.c )
　　and replace it by "#include "

2. mase-mem.c:134: error: static declaration of ‘mem_access_latency’ follows non-static declaration
mase-mem.h:104: error: previous declaration of ‘mem_access_latency’ was here
　　find "mem_access_latency" in mase-mem.h and delete "static"

ns2 multicase problem in x86_64 system

I use ns-allinone-2.31 to build a ns2 enviroment in x86_64 linux system.
But there is a problem while running multicase in dense mode ( i don't this problem also happen in sparse mode). The multicased packets are flooding over the entire network.

The reason of this problem is in "MCastClassifier::classify(Packet *pkt)" in classifier-mcast.cc.

The original code is:
　if (p == 0) {
　　　// Didn't find an entry.
　　　tcl.evalf("%s new-group %d %d %d cache-miss", name(), src, dst, iface);

Try to change into:
　if (p == 0) {
　　　// Didn't find an entry.
　　　tcl.evalf("%s new-group %ld %ld %d cache-miss", name(), src, dst, iface);

ns2 nam編譯問題

使用ns2提供的allinone2.31.tar編譯時,nam會發生下面這個問題

......
nam_stream.o: In function `NamStreamCompressedFile::gets(char*, int)':
nam_stream.cc:(.text+0x1071): undefined reference to `gzgets'
nam_stream.o: In function `NamStreamCompressedFile::NamStreamCompressedFile(char const*)':
nam_stream.cc:(.text+0x10b4): undefined reference to `gzopen'
nam_stream.o: In function `NamStreamCompressedFile::NamStreamCompressedFile(char const*)':
nam_stream.cc:(.text+0x1136): undefined reference to `gzopen'
collect2: ld returned 1 exit status
make: *** [nam] Error 1

這個問題只要把nam資料夾下的Makefile稍作修改即可

LIB = \
-L/home/hct/ns-allinone-2.31/tclcl-1.19 -ltclcl -L/home/hct/ns-allinone-2.31/otcl -lotcl -L/home/hct/ns-allinone-2.31/lib -ltk8.4 -L/home/hct/ns-allinone-2.31/lib -ltcl8.4 -lz \

Gtkmm under Windows using Microsoft Visual Stuido 2005

Gtkmm基本上算是GTK的延伸,差異在於他將GTK修改成C++的語法
在Visual Stuido 2005的安裝方法gtkmm_windows
首先要先下載Gtk+ 跟 Gtkmm development package
若是使用vista的使用者,Visual Stuido 2005須先安裝sp1

照著網頁上的說明即可,不過我編譯的時候出現下列錯誤
LNK1104 : cannot open file 'cairo.lib'
不知道為什麼,明明我都沒有連結到cairo.lib.
最後我把安裝C:\GTK\lib\cairomm-1.0d.lib複製一份名稱改成cairo.lib
這樣就可以正常編譯執行,非常的神奇....

Installing TinyOS 2.0.2

因為我在Vista裝不起來TinyOS, 所以就把腦筋動到Linux下


http://www.tinyos.net/tinyos-2.x/doc/html/install-tinyos.html
照tinyos的網頁安裝即可,我使用的Linux是Suse 10.3
另外我是安裝TI MSP430 Tools
最後在home下的.bashrc加上
export CLASSPATH=$TOSROOT/support/sdk/java/tinyos.jar:.
export TOSROOT=/opt/tinyos-2.x
export TOSDIR=$TOSROOT/tos
export MAKERULES=$TOSROOT/support/make/Makerules
export PATH=/opt/msp430/bin:$PATH

最後如果在make telosb install.1 bel,/dev/ttyUSB0執行時發生can't not find serial
到http://software.opensuse.org/search搜尋 python-serial 安裝後應該就可以成功

VMware Failed to allocate page for guest RAM

Install Flash Player in x86_64 system

1.download nspluginwrapper rpm packages, plugin and viewer are need.
2.install nspluginwrapper
#rpm -ivh nspluginwrapper-i386-0.9.91.4-1.x86_64.rpm
#rpm -ivh nspluginwrapper-0.9.91.4-1.x86_64.rpm

3.download flashplayer from adobo.com
install flash-plugin ,so libflashplayer.so in the /usr/lib64/flash/ or other where,
$locate libflashplayer.so you can find it.

4.$cp libflashplayer.so ~/.mozilla/plugins/
5.$nspluginwrapper -i ~/.mozilla/plugins/libflashplayer.so

GTK2+ 在win32下執行

之前在Linux下使用GTK2+來寫GUI介面，因看到網路上說GTK2+在windows下也能編譯執行，所以就突發奇想試試看能不能把程式移植到windows上。

首先下載GTK2.4 for win32

安裝至電腦裡時，他會出現是否要把library跟include檔案加入到電腦裡已知的編譯環境下。測試過Dec C++ 跟 VC++ ，不過編譯環境要先安裝才會有作用(建議讓GTK2.4幫你加入，因為檔案不少)。

接下來就是編譯GTK的程式，除了上面說的要把library跟include檔案加入到電腦裡已知的編譯環境，還需設定連結(linker)參數，這時候就要在project setting的link裡面，加入如下：
glib-2.0.lib gtk-win32-2.0.lib gdk-win32-2.0.lib gobject-2.0.lib gdk_pixbuf-2.0.lib gthread-2.0.lib gmodule-2.0.lib pango-1.0.lib intl.lib
這樣就能成功使用GTK的library了!

不過使用Dev C++雖然能編譯成功，但執行的時候會有問題。不過VC++就不會 Orz...

Linux下完整支援nfts檔案系統 (讀/寫)

Linux NTFS Project支援 User Space 的 NTFS FileSystem.
這個 Driver 使用 FUSE(Filesystem implement in userspace)做介面,
剛剛試了一下, UTF-8 下中文沒有問題, 可以正常讀寫, 建立目錄.

首先必須安裝fuse：
先下載fuse,解壓縮至目錄下
#./configure
#make
#make install (must at root)

接下來就是安裝ntfs-3g,安裝方式跟fuse安裝方法一樣：
先下載ntfs-3g,解壓縮至目錄下
#./configure
#make
#make install (must at root)

最後就是將ntfs檔案系統掛載到Linux下：
ntfs-3g /dev/sda1 /mnt/windows -o silent,umask=0,locale=zh_TW.utf8

若要在啟動Linux時就直接掛載,則寫在 /etc/fstab
/dev/sda1 /mnt/windows ntfs-3g silent,umask=0,locale=zh_TW.utf8 0 0

不過我測試的結果,可是新建資料夾但是好像不能把資料夾直接複製進去,不知道是不是哪裡設定錯誤？

Kiba-Dock 執行問題

安裝完Kiba-Dock後發現Systray跟Iconediter不能開啟

會出現下面兩個錯誤：
1. ImportError: No module named SimpleGladeApp
2. ImportError: No module named egg.trayicon

上網查了一下,發現解決辦法
Type the following as root:
cp /usr/lib64/python2.4/site-packages/SimpleGladeApp.py /usr/lib64/python2.5/site-packages/
If SimpleGladeApp.py doesn't exist, install avahi package

Install pygtk and python-gnome-extras package

安裝Internet Explorer

在Linux下雖然有Firefix來瀏覽網頁,不過有些網頁用Firefox顯示起來就是有些怪,而且以的還限制只能用IE來開啟.
要在Linux下裝Internet Explorer大部分都是使用wine來安裝,不過我是了很多版本就是裝不起來(在裝IE總是有錯誤訊息) ,最近在網路上有人把裝IE的步驟寫成一個執行程式,它會自動從微軟網頁下載套件然後安裝. 另外他還能選擇要裝什麼語言. 在他的網頁上還宣稱連IE 7都能裝.


首先要先安裝wine,在SuSE的安裝光碟就能找到(因為我裝wine的時候就把wine-tool一起裝了所以 不知道wine-tool是不是一定要奘)
到http://www.tatanka.com.br/ies4linux/news/ 下載 ies4linux
解壓縮後,執行目錄裡的ies4linux (#./ies4linux)

他會自動安裝IE6.0版,不過會問你是否要裝5.5跟5.0的版本以及要安裝甚麼語言

之後就會自動下載套件來安裝了

安裝完成後在桌面就會出現圖示,這時候點看看有沒有IE跑出來啦！

我在別的網站上看到說需要有 cabextract套件,不過我安裝的時候倒是很順利！

安裝"compiz-quinn"

裝SuSE的最初目的就是喜歡他的3S桌面特效,不過現在幾乎每種Linux版本都能裝XGL了. 而且做出來的效果還比SuSE的還多(像在SuSE中啟動compiz後佈景設置只能用預設的)

最近在網路上終於找到能用在SuSE的compiz管理套件"compiz-quinn".他的功能比SuSE的還更多,而且還能更改佈景.

首先在http://software.opensuse.org/download/Compiz-Quinn/SUSE_Linux_10.1/i586/
下載compiz-quinncvs,xgl-cvs,librsvg,libwnck,cgwd-themes然後使用zen-installer安裝就行了(如果有已經安裝過的就不用下載)

安裝完成後在作業階段新增compiz-start.py自動啟動,最後重新登入就會在系統列看到小圖示了
他還能隨意更換不同桌面系統的佈景設定,還有一堆關於XGL的外掛

不過在我電腦用有點不大穩定,有時候把佈景轉換成compiz時整個桌面會掛掉害我重新開機不少次.
可能是顯示卡太嫩吧(內建的X200 >"< )
