Zlib移植

下载 zlib

进入 sylixos 工作空间：

cd /home/user/sylixos_workspace

下载 zlib：

连接在 http://www.zlib.net/ 页面中

进入 zlib 目录：

cd zlib

configure

配置：

./config --prefix=/lib/zlib

修改 Makefile

1:(编译好的 SylixOS 与 cextern 目录根据实际情况设置)

# SylixOS PATH
SYLIXOS_PATH=/home/user/sylixos_workspace/libsylixos
CEXTERN_PATH=/home/user/sylixos_workspace/libcextern

2:

# SYLIXOS includes
INCDIR  = $(SYLIXOS_PATH)/SylixOS
INCDIR += $(SYLIXOS_PATH)/SylixOS/include
INCDIR += $(SYLIXOS_PATH)/SylixOS/include/inet
INCDIR += $(SYLIXOS_PATH)/SylixOS/include/inet/ipv4
INCDIR += $(SYLIXOS_PATH)/SylixOS/include/inet/ipv6
SHLDIR  = $(SYLIXOS_PATH)/Debug
SHLDIR += $(CEXTERN_PATH)/Debug

3:

# SYLIXOS compile and link options
SYLIXOS_CFLAGS=-DSYLIXOS -DSYLIXOS_LIB $(addprefix -I,$(INCDIR)) -mcpu=arm920t -fmessage-length=0 -fno-short-enums
SYLIXOS_EXLIBS=-nostdlib $(addprefix -L,$(SHLDIR)) -lcextern -lvpmpdm -lm -lgcc

4:

CC=arm-none-eabi-gcc

5:

CFLAG = $(SYLIXOS_CFLAGS) $(SYLIXOS_EXLIBS) -shared ......
SFLAG = $(SYLIXOS_CFLAGS) ...... 

6:

LDSHARED=arm-none-eabi-gcc ......
CPP=arm-none-eabi-gcc .......
AR=arm-none-eabi-ar
RANLIB=arm-none-eabi-ranlib

7:

LDSHAREDLIBC=-shared $(SYLIXOS_EXLIBS)

编译

1:

make
make install

2:

在 SylixOS 主机 /lib 中创建 zlib 文件夹, 然后将 make install 的结果拷贝到此处.

3:

创建好相应的符号链接
cd /lib/zlib/lib
ln -s libz.so.1 libz.so
ln -s libz.so.1.2.8 libz.so

4:

修改环境变量 $LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib/zlib/lib varsave
