大家?guī)臀曳�譯一下這段話是什么意思好嗎？

1. PROBLEM:
   
2. 
   
3. When compiling the hclnfsd source code on your NFS Server, you may see the following output:
   
4. 
   
5. gcc: -lrpcsvc: linker input file unused because linking not done
   
6. gcc: -lsocket: linker input file unused because linking not done
   
7. gcc: -lresolv: linker input file unused because linking not done
   
8. gcc: -lnsl: linker input file unused because linking not done
   
9. 
   
10. SOLUTION:
    
11. 
    
12. The message that gcc reported is correct. Its simply a warning message.
    
13. 
    
14. The compiler is informing you that the library was not used because no linking was done. This is because you supplied a library to the command where no linking was done. The compiler is ignoring the extraneous object file.
    
15. 
    
16. The compilation should still continue, and the hclnfsd executable will be created.

我在make 的時(shí)候就出現(xiàn)下面的提示不知道是什么原因。上面是G。CN的一篇外文，我看的不是很明白大家?guī)臀曳�譯一下。謝謝。

編譯的錯(cuò)誤信息一般都是英文的，LZ要提高英文能力。做研發(fā)離不開(kāi)英語(yǔ)。

問(wèn)題：

當(dāng)在NFS服務(wù)器上編譯hclnfsd時(shí)，你可能會(huì)遇到如下的輸出:

gcc: -lrpcsvc: linker input file unused because linking not done
gcc: -lsocket: linker input file unused because linking not done
gcc: -lresolv: linker input file unused because linking not done
gcc: -lnsl: linker input file unused because linking not done

解決:

gcc 給出的報(bào)告是正確的，它只是一個(gè)簡(jiǎn)單的警告信息.

編譯器通知你那個(gè)庫(kù)沒(méi)有被使用因?yàn)闆](méi)有被鏈接，這是因?yàn)槟闾峁┙o編譯器一個(gè)沒(méi)有可鏈接符號(hào)的庫(kù)。編譯器正在忽略無(wú)關(guān)的目標(biāo)文件。

編譯會(huì)繼續(xù)運(yùn)行，并且可執(zhí)行文件hclnfsd也會(huì)生成。

shan_ghost

The compiler is informing you that the library was not used because no linking was done. This is because you supplied a library to the command where no linking was done. The compiler is ignoring the extraneous object file.

編譯器提示你：因?yàn)闆](méi)有做出任何鏈接，所以指定的庫(kù)沒(méi)有被使用。
這個(gè)提示的原因是沒(méi)有在“你在命令行指定的庫(kù)”上生成任何鏈接。
編譯器將忽略這個(gè)無(wú)關(guān)的目標(biāo)文件。

進(jìn)行Make 的時(shí)候就能通過(guò) 但報(bào)上面的linker input file unused because linking not done
請(qǐng)問(wèn)我這樣直接安裝以后會(huì)出什么問(wèn)題嗎？

sleetdrop

Make通過(guò)的這個(gè)應(yīng)該是可以的吧，它提示的只是忽略了一些沒(méi)用到的庫(kù)，你的可執(zhí)行文件應(yīng)該是編譯成功可以使用了的。

我在網(wǎng)上查報(bào) : undefined reference to `_Unwind_Resume'  這個(gè)錯(cuò)誤只要加上   -Wl,-Bdynamic -lgcc_s 這個(gè)參數(shù)就可以了。

但他們的GCC都是在3.2.2  的 我已經(jīng)把他升級(jí)到 2.4.6 了可還是不行。 還是報(bào)
