c – 在Qt中编译巨大的头文件时mingw“太多部分”错误

我试图在Qt(win7)上用mingw32(491_32)编译exprtk.hpp文件( https://exprtk.codeplex.com/ ).

在编译期间,我给出了以下错误消息：

debug\main.o:-1: error: too many sections (35325)

我注意到exprtk.hpp文件很大(> 32000行).

我一直在尝试编译器上的优化标志,但它没有帮助eighter.

如果有人帮助我,我将不胜感激……

问候,

As you’ve already noticed, passing /bigobj to Microsoft’s compiler  causes it to output a munged COFF format with up to 2^31 sections,  which “should be enough for anybody.”
I’ve tested this new option with MinGW-w64 and it works. You need to  pass -Wa,-mbig-obj to gcc to opt-in to big objects (-Wa means pass  this option to the assembler). – Francis Gagné
