ubuntu 14.04 64位系統編譯RT288x_SDK

sudo apt-get install gcc  g++  binutils  patch bzip2  flex  bison  make  autoconf  gettext  texinfo  unzip  sharutils  subversion  libncurses5-dev ncurses-term  zlib1g-dev gawk asciidoc libz-dev git git-man liberror-perl libsigsegv2 mercurial python-iniparse tortoisehg tortoisehg-nautilus python-nautilus build-essential gcc-multilib 

 

 

編譯buildroot

/opt/buildroot-2012.11.1/output/toolchain/gcc-4.6.3/gcc/doc/cppopts.texi:772: @itemx must follow @item
make[2]: *** [doc/cpp.info] 錯誤 1

緣由是ubuntu 14.04版本帶的texinfo版本太高致使，須要降級

wget http://ftp.gnu.org/gnu/texinfo/texinfo-4.13a.tar.gz
tar -zxvf texinfo-4.13a.tar.gz
cd texinfo-4.13
./configure
make
sudo make install

 

 

編譯mksquash

#cd RT288x_SDK/toolchain/mksquash_lzma-3.2
#make
#make install (copy lzma_alone to /opt/buildroot-gcc463/usr/bin/)

 

錯誤1

/usr/bin/ld: mksquashfs.o: undefined reference to symbol 'log10@@GLIBC_2.2.5'
//lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[1]: *** [mksquashfs] 錯誤 1

上網搜了一下，應該缺乏math庫的連接致使的，在編譯選項中增長-lm能夠解決

修改文件RT288x_SDK/toolchain/mksquash_lzma-3.2/squashfs3.2-r2/squashfs-tools/Makefile

mksquashfs: LDLIBS += -lpthread -lunlzma_r -llzma_r -lstdc++ -lm

錯誤2

make: *** [all] 錯誤 2

仍是修改修改文件RT288x_SDK/toolchain/mksquash_lzma-3.2/squashfs3.2-r2/squashfs-tools/Makefile

在最後面增長-lz選項

unsquashfs: LDLIBS += -lunlzma -lz

編譯完成之後，複製到opt下的相應目錄

sudo cp ~/MTK7688_SDK/MediaTek_ApSoC_SDK_4300_20140916/RT288x_SDK/toolchain/mksquash_lzma-3.2/lzma443/C/7zip/Compress/LZMA_Alone/lzma_alone /opt/buildroot-gcc463/usr/bin/

 

 

source make報錯

error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

緣由是缺乏libz.so.1這個庫，能夠經過ubuntu的apt-file search查找對應的軟件包

sudo apt-get install apt-file

以後更新

sudo apt-file update

而後就能夠查找了

$ apt-file search libz.so.1
lib32z1: /usr/lib32/libz.so.1
lib32z1: /usr/lib32/libz.so.1.2.8
libx32z1: /usr/libx32/libz.so.1
libx32z1: /usr/libx32/libz.so.1.2.8
zlib1g: /lib/x86_64-linux-gnu/libz.so.1
zlib1g: /lib/x86_64-linux-gnu/libz.so.1.2.8

選擇安裝lib32z1

sudo apt-get install lib32z1

修改RT288x_SDK/source/vendors/Ralink/***/Makefile

ENTRY=`readelf -h $(ROOTDIR)/$(LINUXDIR)/vmlinux | grep "Entry" | awk '{print $$4}'` ; \

爲

ENTRY=`readelf -h $(ROOTDIR)/$(LINUXDIR)/vmlinux | grep "入口點地址" | awk '{print $$2}'` ; \

主要緣由是原始的編譯腳本是英文環境下編寫的，在中文的環境下，出現匹配異常

Entry Point: 0x8000C120

入口點地址：0x8000C120
