C++ 使用boost库工具/root进行编译时出错

我最近用apt-get在ubuntu上下载了boost库

我已经编写了以下代码，它定义了一个一元函子，然后尝试使用boost库查找它的根（我现在把它全部放在main.cpp中，稍后将其拆分）：

但是，我得到以下错误：

但是，这与我在尝试用C++完成之前使用的原型R代码的计算不一致：

> binomcalc <- function(p, p0, N, B){pbinom(B,N,p)-p0}
> uniroot(binomcalc, c(0,1), p0=0.05, B=75, N=4167)
$root
[1] 0.02178983

$f.root
[1] -0.0009172035

$iter
[1] 12

$estim.prec
[1] 6.103516e-05

>binomcalc单根（binomcalc，c（0,1），p0=0.05，B=75，N=4167）
$root
[1] 0.02178983
$f.root
[1] -0.0009172035
$iter
[1] 12
$estim.prec
[1] 6.103516e-05

我想知道他们为什么不同？我需要调整公差或精度之类的东西吗

谢谢， 本。

我的编译器提到

\usr\include\boost\math\tools\toms748_solve.hpp|283 col 17| note:   template argument deduction/substitution failed:
\usr\include\boost\math\tools\toms748_solve.hpp|468 col 81| note:   deduced conflicting types for parameter 'const T' ('int' and 'double')

所以。。。这很清楚：）解决它：

输出：

Let's take a look at the root
root bracketed: [ 1 , 1 ]
f(1)=0
f(1)=0
max_iter=2

谢谢，有没有办法提高准确性？我已经用工作版本更新了原始问题。是的。但是，你应该将新的问题作为单独的问题发布。非常正确，我可以改变这一点-我想知道是这样还是boost邮件列表会更好我会在这里说/但我有偏见：）
