我尝试使用PGI的C ++编译器编译包含Eigen标头的代码,但得到以下错误:

只要包含Eigen标头,无论编译代码如何,我都会得到相同的错误。更具体地说,我包括以下内容:

#include <Eigen/Eigen>

尝试编写一个简单的&#34; Hello World&#34;程序。除了Eigen的指令外,CMakeLists.txt也是准系统。

cmake_minimum_required(VERSION 3.10)
project(EigenTest)

set(CMAKE_CXX_STANDARD 11)

add_executable(EigenTest main.cpp)

find_package (Eigen3 3.3 REQUIRED NO_MODULE)
target_link_libraries (EigenTest Eigen3::Eigen)

我应该注意到我在macOS Sierra(10.12.6)上,并且我已经尝试了PGI的v17.10和v18.4。没有特殊标志用于编译。安装的Eigen软件包是MacPorts上最新的软件包(eigen3 3.3.4)。

我之前已经非常轻易地使用了Eigen,并且GCC的一切正常。我之前也没有使用PGI的编译器。我试图同时使用两者的原因是我需要在使用Eigen的代码的某些部分使用OpenACC编译指示。

任何帮助我走向正确方向的帮助都将受到赞赏。

addr投放到const void*而不是const char*,错误的上述行(或评论所说的行)在Eigen的源文件中,我不会&#39 ; t再次出现编译错误。我可以从Eigen获得基本功能,但更复杂的代码无法成功链接。产生以下错误:

Undefined symbols for architecture x86_64:

按照@chtz对评论的建议使用-DEIGEN_DONT_VECTORIZE,这会禁用Eigen的内置向量化,项目代码可以编译,链接并成功执行。然而,这产生了一个主要问题,因为Eigen首先用于其矢量化线性代数实现。

至于编译错误,它可能与PGI对@ggael的_mm_castpd_si128类型的支持有关。

总而言之,似乎与PGI的C ++编译器的Eigen兼容性充其量只是部分。
