在 Linux 上编译 SCIP 优化套件 3.2.0

Question

在 linux, CentOS 6.4 (Final) 上编译 scipsuite 时，我收到以下错误：

gcc 版本是 4.4.7

我试过了：

make
make LEGACY=true
make ZLIB=false GMP=false READLINE=false LPSOPT=opt-gccold OPT=opt-gccold

我已经安装了 GMP、ZLIB 和 READLINE 库，以及它们的开发库。

有什么建议吗？

Answer 1

如果你想用gcc 4.4.7 编译SoPlex，你肯定需要设置LEGACY=true（在SCIP 中你需要指定SPX_LEGACY=true）。如果您在 SCIP 优化套件（推荐）中编译代码，LEGACY=true 选项将相应地编译 SCIP 和 SoPlex。

关于spxsolver.h中的另一个错误：第383行，请替换

SPxLPBase::spxout = &newOutstream;

与

SPxLP::spxout = &newOutstream;

显然，gcc 的较新版本在不指定模板说明符的情况下不会抱怨这种用法（SPxLP 实际上是 SPxLPBase <Real>）。
