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!
