プロジェクトにPBCライブラリをインストールしたい。私の64ビットシステムでは、configureスクリプトは64ビットライブラリを簡単にインストールします。しかし、私が使用しなければならないコードは32ビットで構築されています。

私はこのコマンドを試しました（この質問への回答から）：

./configure --build=i686-pc-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"

しかし、'make'を実行するとこのエラーが発生します：

'--help'は、次のフラグを一覧表示します。

Some influential environment variables:
CC          C compiler command
CFLAGS      C compiler flags
LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a nonstandard directory <lib dir>
LIBS        libraries to pass to the linker, e.g. -l<library>
CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if you have headers in a nonstandard directory <include dir>
CPP         C preprocessor
Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.

まず、確認してください。

./configure --help

CFALGS / LDFLAGSをオーバーライドできますか？

はいの場合は、ヘルプ情報に従って実行してください。次に、通常、。/ configureはmakefileを生成してから、「make」コマンドを発行します。設定直後にこのエラーが発生したとおっしゃいましたか？

makeの後にこれらのエラーが発生する場合は、ldがold-residueとリンクしているように見えます。

試しましたか：

make clean;make

@Icarus3に感謝します。あなたは私を正しい方向に向けました。私が使用したコマンドは次のとおりです。

./configure --build=i686-pc-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"

私が走ったとき

./configure --help

ありませんでしたCXXFLAGS。そこで、に変更しましたCPPFLAGS=-m32。そしてそれはうまくいった。
