2000 lines of warnings from Eigen

你可以通过添加编译器选项 -Wno-ignored-attributes 来禁用这些警告，而不需要更改编译器命令。这将告诉编译器不要产生关于忽略属性的警告信息。

例如，你可以将以下选项添加到你的编译器命令中：

g++ -std=gnu++17 -I"/usr/include/R" -DNDEBUG -I"/home/xxxxx/R/x86_64-redhat-linux-gnu-library/4.2/Rcpp/include" -I"/home/xxxxx/R/x86_64-redhat-linux-gnu-library/4.2/RcppEigen/include" -I"/code/cpp/tests" -I/usr/local/include -fpic -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -c testLBFGSandPlainGD.cpp -o testLBFGSandPlainGD.o -Wno-ignored-attributes

这将禁用与忽略属性相关的警告，而不会影响编译后的执行。

I am using g++ 8.5.0 and Eigen library v-3.3.9. When building an application that utilizes Eigen, the compiler generates about 2000 lines of warnings . Below only shows a tiny fraction of them.

These warnings do not affect the execution at all.

How can I disable these warnings preferably without changing the compiler commands?

Thank you!

得分: 3

以下是翻译好的部分：

Eigen使用的相当特殊的优化，以及它作为纯模板库的性质，再加上对多种编译器的支持，意味着它的代码默认情况下会产生大量的编译器警告。为了防止这种情况，它包含一个头文件src/Core/util/DisableStupidWarnings.h，其中包含了专门用于取消这些警告的编译器特定的pragma。

出于某种原因，RcppEigen注释掉了这些pragma。如果我正确理解了这个特定的错误报告，这是CRAN存储库政策的要求。

包不应尝试禁用编译器诊断，也不应删除共享对象中的符号等其他诊断信息。

英文:

The rather peculiar optimizations that Eigen uses plus its nature as a pure template library plus support for a wide range of compilers means that its code would, by default, emit a ton of compiler warnings. To prevent this, it contains a header src/Core/util/DisableStupidWarnings.h with compiler-specific pragmas just for the purpose of deactivating these warnings.

For some reason, RcppEigen comments these pragmas out. If I understand this particular bug report correctly, it is a CRAN Repository Policy to do so.

> Packages should not attempt to disable compiler diagnostics, nor to remove other diagnostic information such as symbols in shared objects.
