編譯linux核心錯誤
作為一個linux核心編譯的新手，第一次為自己編譯一個Linux核心（我正在嘗試使用其他的TCP擁塞控制算法）。
我按照如何編譯 Linux 核心中的步驟進行操作。嘗試執行時
make，出現錯誤：✘ XPS-13-9360 ~/linux_compile/linux-5.1.18 make CALL scripts/checksyscalls.sh CALL scripts/atomic/check-atomics.sh DESCEND objtool CC /home/soar/linux_compile/linux-5.1.18/tools/objtool/arch/x86/decode.o In file included from /usr/include/gelf.h:32:0, from arch/x86/../../elf.h:22, from arch/x86/decode.c:26: /usr/include/libelf.h:46:4: error: unknown type name ‘Elf32_Word’ Elf32_Word ch_type; /* Compression format. */ ^~~~~~~~~~ /usr/include/libelf.h:47:4: error: unknown type name ‘Elf32_Word’ Elf32_Word ch_size; /* Uncompressed data size. */ ^~~~~~~~~~ /usr/include/libelf.h:48:4: error: unknown type name ‘Elf32_Word’ Elf32_Word ch_addralign; /* Uncompressed data alignment. */ ^~~~~~~~~~ /usr/include/libelf.h:53:4: error: unknown type name ‘Elf64_Word’ Elf64_Word ch_type; /* Compression format. */ ^~~~~~~~~~ /usr/include/libelf.h:54:4: error: unknown type name ‘Elf64_Word’ Elf64_Word ch_reserved; ^~~~~~~~~~ /usr/include/libelf.h:55:4: error: unknown type name ‘Elf64_Xword’ Elf64_Xword ch_size; /* Uncompressed data size. */ ^~~~~~~~~~~ /usr/include/libelf.h:56:4: error: unknown type name ‘Elf64_Xword’ Elf64_Xword ch_addralign; /* Uncompressed data alignment. */ ^~~~~~~~~~~ /usr/include/libelf.h:253:8: error: unknown type name ‘Elf32_Ehdr’ extern Elf32_Ehdr *elf32_getehdr (Elf *__elf); ^~~~~~~~~~ /usr/include/libelf.h:255:8: error: unknown type name ‘Elf64_Ehdr’ extern Elf64_Ehdr *elf64_getehdr (Elf *__elf); ^~~~~~~~~~ /usr/include/libelf.h:258:8: error: unknown type name ‘Elf32_Ehdr’ extern Elf32_Ehdr *elf32_newehdr (Elf *__elf); ^~~~~~~~~~ /usr/include/libelf.h:260:8: error: unknown type name ‘Elf64_Ehdr’ extern Elf64_Ehdr *elf64_newehdr (Elf *__elf); ^~~~~~~~~~ /usr/include/libelf.h:269:8: error: unknown type name ‘Elf32_Phdr’ extern Elf32_Phdr *elf32_getphdr (Elf *__elf); ^~~~~~~~~~ /usr/include/libelf.h:271:8: error: unknown type name ‘Elf64_Phdr’ extern Elf64_Phdr *elf64_getphdr (Elf *__elf); ^~~~~~~~~~ /usr/include/libelf.h:274:8: error: unknown type name ‘Elf32_Phdr’ extern Elf32_Phdr *elf32_newphdr (Elf *__elf, size_t __cnt); ^~~~~~~~~~ /usr/include/libelf.h:276:8: error: unknown type name ‘Elf64_Phdr’ extern Elf64_Phdr *elf64_newphdr (Elf *__elf, size_t __cnt); ^~~~~~~~~~ /usr/include/libelf.h:283:43: error: unknown type name ‘Elf32_Off’; did you mean ‘Elf32_Chdr’?

然後我發現它之前被報導過，但它仍然沒有任何解決方案。我能做些什麼？
其實這個是我自己想出來的。看起來編譯器找不到標題作為我的視圖。使用
env命令，CPATH 不在/usr/include/but中/home/user/.local/include:$CPATH，所以我把CPATH 改成，用lkraemer/usr/include/的方法，還是不行，env 顯示CPATH 已經在了。我認為解決和關閉我的ubuntu並休息一下會很困難。但是今天早上我打開了我的ubuntu，它成功了。/usr/include/
