运行 scip 时遇到 libquadmath.0.dylib 的“dyld：未加载错误架构的库”

编程问答 2022-05-29

问题描述

我从预编译二进制文件的 SCIPOptSuite-7.0.2-Darwin-Ipopt-gcc10.sh 安装程序中安装了 SCIP Optimization Suite。 我还通过运行安装了 gcc 和 tbb：

brew install gcc
brew install tbb

错误信息：

$ SCIPOptSuite-7.0.2-Darwin/bin/scip
dyld: Library not loaded: /usr/local/lib/7/i386/libquadmath.0.dylib
  Referenced from: /Users/it/VirtualBox/10运筹学/14SCIP/01install/SCIPOptSuite-7.0.2-Darwin/bin/scip
  Reason: no suitable image found.  Did find:
    /usr/local/lib/7/i386/libquadmath.0.dylib: mach-o,but wrong architecture

还有其他安装了 x86_64 架构的 libquadmath.0.dylib：

$ sudo find / -name libquadmath.0.dylib

$ lipo /usr/local/lib/7/libquadmath.0.dylib -archs
x86_64

我想知道为什么 scip 没有找到这些具有正确架构的 dylib？ 非常感谢。

解决方法

首先确保您安装了正确版本的 gcc，您下载的安装程序要求版本 10。

其次，尝试先安装所有先决条件，然后再重新运行安装程序脚本。

如果这没有帮助，请检查 otool -L SCIPOptSuite-7.0.2-Darwin/bin/scip 和 echo $DYLD_LIBRARY_PATH 的输出以查看相关库是否已加载。

最后，您可以尝试通过将库路径调整为正确的路径来修补二进制文件：

install_name_tool -change /usr/local/lib/7/i386/libquadmath.0.dylib /usr/local/Cellar/gcc/10.2.0_2/lib/gcc/10/libquadmath.0.dylib SCIPOptSuite-7.0.2-Darwin/bin/scip
