在我的ubuntu14.04上“找不到Qt 3.x，请手动设置QT_INCLUDE，QT_LIB，MOC”
我正在尝试从github https://github.com/nii2121/gmapping/blob/master/docs/Instructions.txt安装gmapping包， 然后运行 ./configure 原来是 No 'CXX' environment variable found, using g++. No 'CC' environment variable found, using gcc. Using C++ compiler: g++ Using C compiler: gcc Checking for Qt 3.x ... *** Qt 3.x not found please set QT_INCLUDE, QT_LIB, MOC by hand 有人知道吗？提前致谢！
