Expat build error due to missing includedir in libjingle.scons #184

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Just start building libjingle according to the instructions from README.

What is the expected output? What do you see instead?

What I see:
~/work/libjingle-read-only/talk $ hammer.sh 
scons: Reading SConscript files ...

scons: warning: The build_dir keyword has been deprecated; use the variant_dir 
keyword instead.

keyword instead.

What version of the product are you using? On what operating system?
OSX 10.6.8, Xcode 3.2.6

Please provide any additional information below.
This issue happens because expat sources include <expat_config.h>, which is 
located in third_party/expat-2.0.1, but only third_party/expat-2.0.1/lib is in 
libjingle.scons' includedirs. The fix is straight-forward:

Did you follow the instruction in README file to config the build environment?
* Second, run talk/third_party/expat-2.0.1/configure and
    talk/third_party/srtp/configure.

Yes, I did.

I had this error too. I was compiling from the svn source code. The error was 
corrected following the tip posted here. It seems that libjingle.scons indeed 
has an error because it does not include the folder where expat_config.h is. 
Thanks gsse...@gmail.com

The fix des not seem to be applied in trunk and the problem persists.

It's March 2012 and the proposed patch was not yet propagated to trunk. And it 
does help.

I'm getting the same error, but the fix appears to be for Unix as Windows 
doesn't have a "configure" command.  Please advise what us Windows builders 
should do? (no "switch to Unix" comments please)

Update: Copying expat-2.0.1\Source\Lib\ to expat-2.0.1\Lib\ seems to have 
gotten me past this issue.  Now it complains about missing windows.h, but I 
think that is related to Windows SDK (I had installed it, but not all files, so 
waiting on the 4GB download/install now).
