installation - QGIS 2.4 compilation error on Redhat 6.2 -


i try compil qgis 2.4 scratch (aka source) on redhat 6.2 server (please don't ask me why...).

i have installed pre-requisites, applied patch 0001-fix-build-failure-with-gcc-4.4-bug-10762.patch (following this: https://hub.qgis.org/attachments/7755/0001-fix-build-failure-with-gcc-4.4-bug-10762.patch) , configure qgis using install file:

mkdir build-master ccmake .. <configure> make

unfortunatly, have following

any idea ?

thanks in advance.

the expat lib not included during compil.

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