Issues while build insight-6.8-1 with –target=spare-elf configuration

使用 insight-6.8-1 

% ../insight-6.8-1/configure --target=sparc-elf --prefix=$OPT/sparc-elf-4.7.0 --disable-nls --disable-werror

會出現以下 error messages:

...
/GNU/SRC/insight-6.8-1/sim/erc32/float.c:173:2: warning: #warning no fpu trap support for this target [-Wcpp]

查了很久之後，發現是 link erc32 時少了 ncurses 這個 library，也就是少了 -lncurses。
解法：patch insight-6.8-1 source code:
edit ./insight-6.8-1/sim/erc32/Makefile.in 

 
Line.25:    SIM_EXTRA_LIBS = $(READLINE_LIB) $(TERMCAP_LIB) -lm -lncurses

重新編譯安裝就OK了!

% ../insight-6.8-1/configure --target=sparc-elf --prefix=$OPT/sparc-elf-4.7.0 --disable-nls --disable-werror
% make
% make install

Install TRAP (TRansaction level Automatic Processor generator)

發佈日期: 作者:

安裝完 SystemC-2.2.0 and TLM 後，
在來安裝 TRAP 來玩玩看，這裡有詳細的安裝步驟說明。

一些準備工作
請先確認系統是否已安裝以下的 Library or Tools
libELF, SystemC, TLM, Boots, Python, networkx

Checkout TRAP Source Code

% svn checkout http://trap-gen.googlecode.com/svn/trunk/ trap-gen

Compile and Install TRAP

% cd trap-gen
% ./waf configure --with-systemc=/opt/systemc/systemc-2.2.0 --prefix=/opt/systemc/trap
% ./waf
% ./waf install

Compile LEON3 Processor

% cd processors/LEON3
% python LEON3Arch.py
% cd processors
% ./waf configure --with-systemc=/opt/systemc/systemc-2.2.0 --with-tlm=/opt/systemc/TLM-2009-07-15 --with-trap=/opt/systemc/trap
% ./waf

TRAP 產生的 CPU Simulator 可以有四種類型：funcLT, funcAT, accLT, accAT

    funcLT : Instruction-Accurate with loosely-timed TLM interfaces
    funcAT : Instruction-Accurate with accurate-timed TLM interfaces
    accLT : Cycle-Accurate with loosely-timed TLM interfaces
    accAT : Cycle-Accurate with accurate-timed TLM interfaces

但這次編譯，只會生出 funcLT and funcAT。

Install cross compiler
有已經做好的 sparc-elf, arm-elf compiler，替我省下不少時間！
若要自己做 cross compiler，要記得 compiler 安裝完後要將 BSP 檔案 copy 到 compiler 安裝目錄，以 sparc-elf 為例：

% cp $(TRAP_SRC_DIR)/BSP_and_Compiler/sparc/* $(SPARC_ELF_INSTALL_DIR)/sparc-elf/lib
% sparc-elf-gcc -c exceptionTrap.S -o exceptionTrap.o
% sparc-elf-gcc -c libcStub.c -o libcStub.o
% sparc-elf-gcc -c osemu-crt0.S -o osemu-crt0.o

run Hello-World
hello.c

#include "stdio.h"
int main(void) {
    printf("Hello Worldn");
}

Compile hello.c

% sparc-elf-gcc -specs=osemu.specs -g -O2 hello.c -o hello

Simulate with funcAT

% $(TRAP-SRC-DIR)/processors/LEON3/processor/_build_/funcAT/funcAT -a hello

OpenSuSE 11.1 上的 TCL Library

發佈日期: 作者:
回覆

閒閒沒事
把之前在 Mac OS 上 跑的 NAND Flash Static Wear Leveling 的 EV程式
拿到 SuSE 上跑，結果居然 Compile 不起來
發現是 “-ltcl” 無法 link 到 正確的 TCL Library
若將之改為 “-ltcl8.5” 就 OK
嗯
好像是 TCL Library 在 Install 時有問題
自己動手修正：

$ (cd /usr/lib; sudo ln -s libtcl8.5.o libtcl.o)
$ (cd /usr/lib64; sudo ln -s libtcl8.5.o libtcl.o)

這樣 “-ltcl” 就 OK 了。
