20091110 初步安裝編譯完成
 

（系統環境：colinux + Ubuntu 9.04）
我是用colinux建立好網路環境再用PUTTY連過去編譯
底下 紅色字 是我有卡到的地方 藍色字是下的指令

0.編譯之前請先裝 build-essential 

不裝的話後面都不能跑的 一開始我就是沒裝 結果一直出現Unable to figure out how to do 64 bit arithmetic  比對之前在別台已經裝好的ecos 才發現 很多lib沒裝到

sudo apt-get install build-essential

1.裝載Tcl譯程式和libstdc++5：

root@colinux:～/work$sudo apt-get install tcl8.5 libstdc++5

2.然后按照ecos官網輔助說明，下載檔案ecos-install.tcl：

任選一個吧
wget --passive-ftp ftp://ftp.csie.nctu.edu.tw/pub/Unix/CYGNUS/ecos/ecos-install.tcl
wget --passive-ftp ftp://ftp.twaren.net/pub/Unix/Sourceware/ecos/ecos-install.tcl
wget --passive-ftp ftp://ftp.cis.nctu.edu.tw/pub/csie/Software/Unix/CYGNUS/ecos/ecos-install.tcl

3.執行這個檔案：

root@colinux:~/work$ sh ecos-install.tcl

如果上面步驟有說PORXY錯誤那就換一個網址重做一次吧
記得如果已經有下檔案了 要先砍掉

4.裝載過程中，我選取了(1)arm-eabi 用于ARM (ARM7TDMI, ARM9, XScale)開發。

在我的裝載目錄/opt/ecos中，目錄和主要檔案為：

ecos3.0 ===> ecos3.0來源檔

gnutools ===> arm-eabi交叉編譯工具

ecosenv.csh ===> csh下環境變數設定程式檔

ecosenv.sh ===> bash下環境變數設定程式檔

5. 執行環境變數設定程式檔檔案，使系統可以找到arm-eabi工具：

root@colinux:/opt/ecos$source ecosenv.sh

檢查一下：

root@colinux:/opt/ecos$echo $PATH

/home/myz/ecos/gnutools/arm-eabi/bin:/home/myz/ecos/ecos-3.0/tools/bin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin:/usr/games:/usr/local/real:.

環境這樣就大致ok了開始編譯囉

編譯ECOS

基本上是參照：http://mkl-note.blogspot.com/2008/07/ecos-building-note.html

由于他所用的是cvs版的，我用的是三月的ecos3.0發布版本，有些指令和目錄架構不太一樣了。

1. 裝載必須的包檔案（若下一步驟中出現configure: error: unable to locate Tcl configuration file tclConfig.sh錯誤就是沒有裝載必要的包，小心！）

root@colinux:/opt/ecos/ecos3.0$sudo apt-get install tcl tcl-dev automake autoconf2.13 texinfo tk tk-dev

2. 建立一個ecos-host

（詳見README.host和README.txt）

root@colinux:/opt/ecos/ecos3.0$mkdir ecos-host; cd ecos-host

3. 配置一下，注意：在ecos-host目錄下進行，并且根據文件要求，在每次添加新的驅動時必須在頂層configure一下。選項--with-tcl-version=8.4是必須的，否則出現找不到tclConfig.sh錯誤。

（或者參照http://mkl-note.blogspot.com/2008/07/ecos-building-note.html中的：TCL_INC_DIR=/usr/include/tcl8.4 ../configure --host=i686-linux-gnu --with-tcl-version=8.4 我沒有試過。）

root@colinux:/opt/ecos/ecos3.0/ecos-host$../configure --host=i686-linux-gnu --with-tcl-version=8.4

4. make一下

root@colinux:/opt/ecos/ecos3.0/ecos-host$make CFLAGS="-march=i686" CXXFLAGS="-march=i686"

5. install （注意若裝載在預設目錄下要有許可權）

root@colinux:/opt/ecos/ecos3.0/ecos-host$sudo make install

6. 檢視支援的裝置清單，清單太長，在此省略

root@colinux:/opt/ecos/ecos3.0/ecos-host$cd ..

root@colinux:/opt/ecos/ecos-3.0$./ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig list

7. 生成redboot

root@colinux:/opt/ecos/ecos-3.0$ mkdir ecos-build-redboot

root@colinux:/opt/ecos/ecos-3.0$ cd ecos-build-redboot

建立arm9 目標

root@colinux:/opt/ecos/ecos-3.0/ecos-build-redboot$ ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig new excalibur_arm9 redboot

U CYGPKG_HAL_ARM_ARM9_ARM922T, new inferred value 1

U CYGSEM_HAL_USE_ROM_MONITOR, new inferred value 0

U CYGIMP_HAL_COMMON_INTERRUPTS_USE_INTERRUPT_STACK, new inferred value 0

輸入配置檔案

root@colinux:/opt/ecos/ecos-3.0/ecos-build-redboot$ ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig import ../packages/hal/arm/arm9/excalibur/v3_0/misc/redboot_RAM.ecm

建立樹

root@colinux:/opt/ecos/ecos-3.0/ecos-build-redboot$ ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig tree

編譯

root@colinux:/opt/ecos/ecos-3.0/ecos-build-redboot$make

看一下結果檔吧

root@colinux:/opt/ecos/ecos-3.0/ecos-build-redboot$ ls install/bin

redboot.bin redboot.elf redboot.hex redboot.img redboot.srec

我們要的redboot.*就生成了。

8. 生成kernel core

root@colinux:/opt/ecos/ecos-3.0/ecos-build-redboot$ cd ..

root@colinux:/opt/ecos/ecos-3.0$ mkdir ecos-build-kernel;cd ecos-build-kernel

root@colinux:/opt/ecos/ecos-3.0/ecos-build-kernel$ ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig new excalibur_arm9 kernel

U CYGPKG_HAL_ARM_ARM9_ARM922T, new inferred value 1

root@colinux:/opt/ecos/ecos-3.0/ecos-build-kernel$ ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig resolve

建立樹

root@colinux:/opt/ecos/ecos-3.0/ecos-build-kernel$ ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig tree

編譯

root@colinux:/opt/ecos/ecos-3.0/ecos-build-kernel$ make

看一下結果檔吧

root@colinux:/opt/ecos/ecos-3.0/ecos-build-kernel$ ls install/lib/

extras.o libextras.a libtarget.a target.ld vectors.o

root@colinux:/opt/ecos/ecos-3.0/ecos-build-kernel$ ls /opt/ecos/ecos-3.0/packages/hal/arm/arch/v3_0/src/

arm.ld context.S hal_mk_defs.c redboot_linux_exec.c

arm_stub.c hal_misc.c hal_syscall.c vectors.S

9. 生成網路層

root@colinux:/opt/ecos/ecos-3.0/ecos-build-kernel$ cd ..

root@colinux:/opt/ecos/ecos-3.0$ mkdir ecos-build-net; cd ecos-build-net

root@colinux:/opt/ecos/ecos-3.0/ecos-build-net$ ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig new excalibur_arm9 net

U CYGPKG_HAL_ARM_ARM9_ARM922T, new inferred value 1

U CYGBLD_ISO_STRUCTTIMEVAL_HEADER, new inferred value

U CYGBLD_ISO_FNMATCH_HEADER, new inferred value

檢查衝突

root@colinux:/opt/ecos/ecos-3.0/ecos-build-net$ ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig resolve

建立樹

root@colinux:/opt/ecos/ecos-3.0/ecos-build-net$ ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig tree

編譯

root@colinux:/opt/ecos/ecos-3.0/ecos-build-net$ make

看一下結果檔吧

root@colinux:/opt/ecos/ecos-3.0/ecos-build-net$ ls install/lib

extras.o libextras.a libtarget.a target.ld vectors.o

10. 生成eCos hello程式

root@colinux:/opt/ecos/ecos-3.0/ecos-build-net$ cd ..

root@colinux:/opt/ecos/ecos-3.0$ mkdir hello-app; cd hello-app

複製例子程式到目前目錄下

root@colinux:/opt/ecos/ecos-3.0/hello-app$ cp ../examples/hello.c ../examples/build_Makefile ../examples/build_Make.params .

使檔案有執行許可權

root@colinux:/opt/ecos/ecos-3.0/hello-app$ chmod +x build_Makefile build_Make.params

root@colinux:/opt/ecos/ecos-3.0/hello-app$ SRCS=hello.c DST=hello ./build_Makefile ../ecos-build-net

編譯

root@colinux:/opt/ecos/ecos-3.0/hello-app$ make

arm-eabi-gcc -c -finline-limit=7000 -Wall -Wpointer-arith -Wstrict-prototypes -Wundef -Wno-write-strings -mno-thumb-interwork -mcpu=arm9 -g -O2 -ffunction-sections -fdata-sections -fno-exceptions -I/home/myz/ecos/ecos-3.0/ecos-build-net/install/include hello.c

arm-eabi-gcc -mno-thumb-interwork -mcpu=arm9 --no-target-default-spec -Wl,--gc-sections -Wl,-static -g -O2 -nostdlib -L/home/myz/ecos/ecos-3.0/ecos-build-net/install/lib -Ttarget.ld hello.o -o hello

看一下結果檔吧

root@colinux:/opt/ecos/ecos-3.0/hello-app$ ls

build_Makefile build_Make.params hello hello.c hello.o Makefile Make.params

用objcopy轉換格式
root@colinux:/opt/ecos/ecos-3.0/hello-app$ arm-eabi-objcopy -O srec hello hello.srec -v
copy from `hello'

[elf32-littlearm] to `hello.srec' [srec]

root@colinux:/opt/ecos/ecos-3.0/hello-app$ arm-eabi-objcopy -O binary hello hello.bin -v

copy from `hello' [elf32-littlearm] to `hello.bin' [binary]

root@colinux:/opt/ecos/ecos-3.0/hello-app$ ls

build_Makefile hello hello.c hello.srec Make.params

build_Make.params hello.bin hello.o Makefile

總結：

這裡大致完就完成了

基本上上面有用到 ../ecos-host/tools/src/tools/configtool/standalone/common/ecosconfig 這個的 直接打 ecosconfig 應該可以直接用

ecosconfig 其實就是一個智能化的建立工具，利用它可以生成我們想要的工程，修改配置，加減包，生成Makefile，最后生成之后就可以用make直接呼叫Makefile，產生目標檔案。

ecosconfig是一個指令行工具，其實eCos也提供了一個GUI的工具configtool，和ecosconfig 都位于tools/bin目錄下。
因為我是用colinux 所以pc端須在裝xming 才能開囉(請看續集)
