Redhat 6.2 上的 QGIS 2.4 编译错误

Question

我尝试在 Redhat 6.2 服务器上从头开始编译 QGIS 2.4（又名源代码）（请不要问我为什么...）。

我已经安装了所有的先决条件，应用了补丁 0001-Fix-build-failure-with-gcc-4.4-bug-10762.patch（如下：https://hub.qgis.org/attachments/7755/0001-Fix-build-failure-with-gcc-4.4-bug-10762.patch）并使用 INSTALL 文件配置 QGis：

mkdir build-master
ccmake ..
<configure>
make

不幸的是，我有以下情况

$ make

看起来它没有在 /usr/local 中找到 Expat 库：

$ ll /usr/local/include/expat*
-rw-r--r--. 1 root root  3364 Jun 15 10:21 /usr/local/include/expat_external.h

有什么想法吗？

提前致谢。

找到工作地点。

编译期间不包含 expat 库。

cd build-master
find src/ -name link.txt | xargs -0 sed -i '' -e 's/\-lsqlite3/\-lsqlite3\ \-lexpat/g'
make
