Chrome 编译错误汇总

        由于各种你懂的原因，訪问google的服务总是出错，先是hosts不工作。代理也不好使，最后最终能够短暂訪问了。我的版本号还是採用svn维护的，直接svn update也不行。试试git吧，一晚上才下载了120M，这得要猴年马月才干下完那。

找找tarball吧，TNND，尽然google删除了tarball！好在能够通过git的tgz方式变通的拿到tarball。一更新得到提示：ubuntu14.04不支持。算了，再整个30G的空间装个Ubuntu12.04吧，“尝尽了生活的苦。找不到能够相信的人”。

下了个dep_tool又不通了。一执行gclient报错：

gclient runhooks:

/.gclient: line 8: solutions: command not found

./.gclient: line 9: name: command not found
./.gclient: line 10: url: command not found
./.gclient: line 11: custom_deps: command not found

./.gclient: line 22: syntax error near unexpected token `}'
./.gclient: line 22: `  }'

算了，那就不更新吧，直接在老版本号上build吧：

./build/install-build-deps.sh

提示我64位的kernel编译32位的代码不再获得推荐：

We no longer recommend that you use this script to install
32bit libraries on a 64bit system. Instead, consider using
the install-chroot.sh script to help you set up a 32bit
environment for building and testing 32bit versions of Chrome.

If you nonetheless want to try installing 32bit libraries
directly, you can do so by explicitly passing the --lib32
option to install-build-deps.sh.
Exiting without installing any 32bit libraries.

逗我玩呢。劝我改用install-chroot.sh？

./build/install-chroot.sh

The following targets are available to be installed in a chroot:
   1: breezy
   2: dapper
   3: edgy
  26: stable
  27: testing
  28: trusty
  29: unstable
  30: utopic
  31: vivid
  32: warty
  33: wheezy
  34: woody

You are running a 64bit kernel. This allows you to install either a
32bit or a 64bit chroot environment. Which one do you want (32, 64) 32

I: Retrieving Release
W: Cannot check Release signature; keyring file not available /usr/share/keyrings/debian-archive-keyring.gpg
I: Retrieving Packages

算了，还是取消用这个编译吧：加上--lib32

./build/install-build-deps.sh --lib32

build/gyp_chromium -Dflag1=value1 -Dflag2=value2

然后编译：make chrome -j4

出错了：

net/base/x509_certificate_nss.cc: In function ‘void net::{anonymous}::ParsePrincipal(CERTName*, net::CertPrincipal*)’:
net/base/x509_certificate_nss.cc:75:46: error: invalid conversion from ‘char* (*)(const CERTName*) {aka char* (*)(const CERTNameStr*)}’ to ‘CERTGetNameFunc {aka char* (*)(CERTNameStr*)}’ [-fpermissive]

改之：

  // Get CN, L, S, and C.

#if Michael_Chromium_Patch

      CERTGetNameFunc get_name_funcs[4] = {
               (char*(*)(CERTNameStr*))CERT_GetCommonName, (char*(*)(CERTNameStr*))CERT_GetLocalityName,
              (char*(*)(CERTNameStr*))CERT_GetStateName, (char*(*)(CERTNameStr*))CERT_GetCountryName };
#else
       CERTGetNameFunc get_name_funcs[4] = {
               CERT_GetCommonName, CERT_GetLocalityName,
               CERT_GetStateName, CERT_GetCountryName };

#endif

make chrome -j

My god! crash :(

调试一下吧：

删除这个Local State，chrome就跑起来了，原因就是第一次run起来chrome后，我点击了“是否恢复上次的网页”的是button，导致本地状态解析出错。请看此文件末端的一堆seed数据(它就是老鼠)：
