我正在尝试构建最新版本的valide (0.7.1)
我已经在我的机器（Ubuntu 10.0.4 LTS）上成功构建了 VALA（v 0.17.0）。当我跑
./waf configure在 valide src 目录中，我得到以下输出：
Checking for program gcc or cc : /usr/bin/gcc
Checking for program cpp : /usr/bin/cpp
Checking for program ar : /usr/bin/ar

Perhaps you should add the directory containing `libvala-0.12.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libvala-0.12' found
/path/to/valide-0.7.1/wscript:53: error: the configuration failed (see '/path/to/valide-0.7.1/_build_/config.log')
我在我的系统上检查了相关的 .pc 文件
me@yourbox:~/path/to/valide-0.7.1$ find ../vala/ -name 'libvala*.pc' -type f
../vala/vala-0.17.0/libvala-0.18.pc
../vala/vala-0.17.0/libvala.pc
然后我按如下方式导出了相关的 ENV VAR：
export PKG_CONFIG_PATH=/path/to/vala/vala-0.17.0
然后我运行./waf configure。令我沮丧的是，我得到了与之前发布的完全相同的输出。
在 Ubuntu 10.0.4 LTS 上构建验证需要解决什么问题？
