我对C++的知识有限。我试图编译一个C++库,并在运行以下头文件的make文件时:
mcmc_dhs.h
#include <algorithm>
#include <map>
// intrinsic shape and (reduced) shear just add?
//#define WLNOISE
// use shear instead of reduced shear for model
//#define NOREDSHEAR
/// parameters for the M200-concentration relation
const number mcreal[2] = {9.59,-0.102}; // Dolag et al. (2004)
//const number mcreal[2] = {5.26,-0.100}; // Neto et al. (2007) [Millenium Run]
/// critical density at z=0 (h100=1) in [Msun/Mpc^3]
const number rhocrit = exp(log(rhoCrit)+3.*log(Mpc)-log(Msun));
/// two extra halo parameters: r200 (and concentration: 2)
#define PARAMS 1
/// define region (square; twice value here) about halo that considers sources for model
#define REGION 10.0*arcmin
class mcmc_dhs : public mcmc
{
public:
mcmc_dhs() :
data(), cosmohandler(0.3,0.7,0.21,0.8,0.04),
lenseff(), intrvar()
{
boundaries =
{{0,512},{0,512},{0.01,5.},{100.,3000.},{0.1,50}};
}
~mcmc_dhs() {}
/// size of grid for looking up sources
static const int Ngrid = 200;
它会返回以下错误信息:
mcmc_dhs.h:55:67: warning: extended initializer lists only available with -std=c++11 or -std=gnu++11 [enabled by default]
boundaries = {{0,512},{0,512},{0.01,5.},{100.,3000.},{0.1,50}};
^

的支持。即使使用-std=c++11
,您仍将获得相同的错误(尽管没有警告)。即使在C++98代码中,由于现代g ++编译器(> = 4.9)将大括号解释为std :: initializer_list
(即使您不使用-std=c++11
编译),您也会收到警告。他们认为这是一种扩展,并且默认情况下启用(请参见警告消息)。 - vsoftco
