簡単な質問があります。

私の問題は、amd64 マシンで 32 ビット コードをコンパイルしていることです。これが出力です

/usr/bin/ld: i386 architecture of input file `MandamiFuzzyModel.o' is incompatible with i386:x86-64
ですから、明らかに問題はここにあります。ここでは、32 ビット コードを 64 ビット リンカとリンクしています。
g++ longRangeNavigator.o GALRN.o InternalMap.o MandamiFuzzyModel.o MembershipFunctions_1D.o Utils.o ../../common/configFile/configFile.o -o longRangeNavigator
このアクションが実行される Makefile niether を完全には理解していません。-m32 パラメータを追加したいだけです。
