T113 SDK编译

T113 SDK建议使用Ubuntu1804版本来编译，避免出现其他因版本差别而出现的错误。

sudo dpkg --add-architecture i386
sudo apt install -y git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib tofrodos python markdown libxml2-utils xsltproc zlib1g-dev:i386 gawk texinfo gettext build-essential gcc libncurses5-dev bison flex zlib1g-dev gettext libssl-dev autoconf libtool linux-libc-dev:i386 wget patch dos2unix tree u-boot-tools

T113 SDK编译需要使用Python2，所以先安装Python2并配置为默认版本。

sudo apt install python2
sudo ln -s /usr/bin/python2 /usr/bin/python

配置SDK编译选项

./build.sh config

执行编译

./build.sh

编译过程中会出现一些错误，需要手动来修改部分代码来解决这些错误，直到编译顺利完成。

Issue1

gdbusauth.c:1302:11: error: ‘%s’ directive argument is null

修改为如下

if(line != NULL)
    debug_print ("SERVER: WaitingForBegin, read '%s'", line);

Issue2

gdbusmessage.c:2702:30: error: ‘%s’ directive argument is null

修改为如下

if(signature_str!= NULL)
    tupled_signature_str = g_strdup_printf ("(%s)", signature_str);

Issue3

/usr/bin/ld: dtc-parser.tab.o:(.bss+0x10): multiple definition of `yylloc'; dtc-lexer.lex.o:(.bss+0x0): first defined here

 dtc-lexer.l 文件中，修改为如下

extern YYLTYPE yylloc;

Issue4

gawk: ./mkerrnos.awk:86: warning: regexp escape sequence `\#' is not a known regexp operator
gawk: ./mkerrcodes1.awk:84: warning: regexp escape sequence `\#' is not a known regexp operator
gawk: ./mkstrtable.awk:113: warning: regexp escape sequence `\#' is not a known regexp operator
gawk: ./mkerrcodes.awk:88: warning: regexp escape sequence `\#' is not a known regexp operator

文件中对应的行，改为如下

sub (/#.+/, "");

去年了井号前的反斜杠。

Issue5

编译libgpg-error-1.33时，出现的如下错误

gawk: fatal: cannot use gawk builtin `namespace' as variable name

将该目录下的 Makefile、Makefile.am、Makefile.in、mkstrtable.awk 里的 namespac e 都改为 pkg_namespace

Issue6

  return errnos_msgstr + errnos_msgidx[idx];
         ^~~~~~~~~~~~~

如果libgpg-error-1.27/src/errnos-sym.h 文件为空，可以添加一下内容到文件中。记得每个变量前缀为errnos。
