Getting Firefox 3.6.23 to compile under LFS

Using the instructions from the BLFS book with the latest available 3.6 build of Firefox, I was able to achieve success. I figured I’d try out 3.6 before going onto something with a terribly inflated version number, and as per usual, ran into some problems:

• Rebuild libpng-1.5.5 with APNG support. This is actually optional as I ended up commenting out the –with-system-png option in mozconfig.
• In the suggested mozconfig, comment out the last two lines:
  

  #ac_add_options --with-system-libxul
  #ac_add_options --with-libxul-sdk=/usr/lib/xulrunner-devel-1.9.2.13

  to create a standalone build.

• Apply the GCC patch from this Bugzilla report (direct download).
• Apply a partial patch from the Chromium project of all places. I’ve customized it here:

• Apply a GCC4.6-specific patch to fix various .cpp files. Some parts of the patch will fail; that’s expected.
• Manually edit layout/style/nsCSSRuleProcessor.cpp and go to line 1199. Change the source code as follows:
  
  const nsCaseInsensitiveStringComparator ciComparator;
  should become
  
  const nsCaseInsensitiveStringComparator ciComparator = nsCaseInsensitiveStringComparator();
  
• For the toolkit/components/places/src/SQLFunctions.cpp file, change line 126 to:
  const nsCaseInsensitiveStringComparator caseInsensitiveCompare = nsCaseInsensitiveStringComparator();
• In toolkit/crashreporter/google-breakpad/src/common/linux/language.cc, make sure line 51 is changed to:
  const CPPLanguage CPPLanguageSingleton = CPPLanguage();
• In toolkit/xre/nsAppRunner.cpp, line 990:
  
  static const nsXULAppInfo kAppInfo = nsXULAppInfo();
  
• While this is resolved in newer Firefox versions, copy security/coreconf/Linux2.6.mk to security/coreconf/Linux3.1.mk to add support for the 3.1 kernel.

Your reward will be a working Firefox installation:
