我有一個簡單的問題。添加-m32參數到Makefile命令
這是我的Makefile

我的問題是，我在AMD64機器正在編寫一個32位代碼。 這是輸出

/usr/bin/ld: i386 architecture of input file `MandamiFuzzyModel.o' is incompatible with i386:x86-64
因此，很明顯的問題是在這裏。在哪裏我連接一個64位連接器的32位代碼。
g++ longRangeNavigator.o GALRN.o InternalMap.o MandamiFuzzyModel.o MembershipFunctions_1D.o Utils.o ../../common/configFile/configFile.o -o longRangeNavigator
我不完全理解Makefile這個動作是否完美。 我只想添加-m32參數。
調用鏈接器命令其值'LDFLAGS' 。但是設置'CXX = g ++ -m32'更容易。 –
