Question

在linux，CentOS 6.4（最终版）上编译scipsuite时，我收到这些错误：

help = $('<img src="/images/buttonup.png">')
help.css({ width: "10px" });
help.css({ width: "calc(10px + 10px)" });
if (help.width() == 20) var calcSupport = true; else var calcSupport = false;

gcc版本是4.4.7

我试过了：

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？

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）。如果您正在编译SCIP Optimization Suite中的代码（推荐），则选项LEGACY=true将相应地编译SCIP和SoPlex。

关于spxsolver.h中的其他错误：在第383行，请替换

SPxLPBase::spxout = &newOutstream;

与

SPxLP::spxout = &newOutstream;

显然，较新版本的gcc在没有指定模板说明符的情况下不会抱怨此用法（SPxLP实际上是SPxLPBase <Real>）。

在Linux上编译SCIP Optimization Suite 3.2.0
