编译libjingle的问题

Question

我下载并安装了libjingle-0.5.2.zip,并根据README还下载并安装了swtoolkit.0.9.1.zip,scons-local-2.1.0.alpha.20101125.tar.gz和expat-2.0. 1.tar.gz,并通过cvs下载获得nrtp.在覆盖了我的Makefile两次,尝试按照写得很差的自述文件后,我想出了几乎可以工作的以下Makefile:

# First, make sure the SCONS_DIR environment variable is set correctly.
SCONS_DIR ?= /usr/src/scons-local/scons-local-2.1.0.alpha.20101125/
#SCONS_DIR ?= /usr/src/scons-local/
export
default: build
# Second, run talk/third_party/expat-2.0.1/configure...
talk/third_party/expat-2.0.1/Makefile:
    cd talk/third_party/expat-2.0.1 && ./configure
# ...and talk/third_party/srtp/configure.
talk/third_party/srtp/Makefile:
    cd talk/third_party/srtp && ./configure
# Third, go to the talk/ directory and run $path_to_swtoolkit/hammer.sh. Run
# $path_to_swtoolkit/hammer.sh --help for information on how to build for
# different modes.
build: talk/third_party/expat-2.0.1/Makefile talk/third_party/srtp/Makefile
    cd talk && ../../swtoolkit/hammer.sh
help:
    ../swtoolkit/hammer.sh --help

但是,make给我以下错误:

jcomeau@intrepid:/usr/src/libjingle-0.5.2$ make
cd talk && ../../swtoolkit/hammer.sh
*** Error loading site_init file './../../swtoolkit/site_scons/site_init.py':

  File "/usr/lib/python2.6/posixpath.py", line 67:
    elif path == '' or path.endswith('/'):
make: *** [build] Error 2

我猜测其中一个包中的新东西(一个'Dir'对象是预期POSIX路径字符串的位置)正在破坏构建过程,但是哪一个？这里有太多的残余层让我跟随.当然,我可以继续尝试更旧的软件包,特别是对于swtoolkit和scons,但如果这里的任何人已成功编译libjingle并且可以向我推进正确的方向,我会很感激.

我对这个项目并不熟悉,但我认为我已经找到了解决这个问题的方法.您需要在swtoolkit/site_scons/site_init.py中Dir使用这些实例进行str()转换.这样他们就可以安全地进行评估path.endswith('/').奇怪的是,在构建基础架构的主要部分中,这样的问题将存在很长时间:

330号线:

SCons.Script.Main._load_site_scons_dir(
    str(SCons.Node.FS.get_default_fs().SConstruct_dir), site_dir)

450行:

SCons.Script.Main._load_site_scons_dir(
    str(SCons.Node.FS.get_default_fs().SConstruct_dir), None)
