いくつかの行が次のようになっていることに気付くでしょう：

warning: file-aligned section .text extends beyond end of file warning: checksum areas are greater than image size. Invalid section table?

これは正確に何を意味し、これは私が心配する必要があるものですか？

私はページを見つけました http://www.rodsbooks.com/efi-bootloaders/secureboot.html この警告について言及しています：

[...]
warning: file-aligned section .text extends beyond end of file warning: checksum areas are greater than image size. Invalid section table? 
[...]

この例は、2つの警告を示しています。私はそれらを完全に理解しているとは主張しませんが、彼らは何の害もしないようです。（このような警告は、数年前よりも2015年には一般的ではないようです。）.

この著者が心配していなければ、私もそうではありません。
