arm_linux_yaffs2文件系統(tǒng)移植到內(nèi)核GUN編譯錯誤問題處理

1、yaffs2更新的比較慢，跟不上內(nèi)核的更新速度.所以只能自己做些修改firststep剛開始從官網(wǎng)下載下來的直接打補(bǔ)丁后會出現(xiàn)一系列的錯誤.如下：*fs/yaffs2/yaffs_vfs.c:Infunction'yaffs_readpage_nolock':fs/yaffs2/yaffs_vfs.c:286:34:error:'structfile'hasnomembernamed'f_dentry'obj=yaffs_dentry_to_obj(f->f_dentry);Afs/yaffs2/yaffs_vfs.c:Infunction

9、Waitingforunfinishedjobs.make1:*/home/anzyelay/Downloads/buildroot-2016.05/output/build/linux-4.4.16/.stamp_builtError2make:*_allError2*上面有三個問題要解決 1:error:"structfile'hasnomembernamed'f_dentry' 2:error:'new_sync_read/write'undeclaredhere 3:error:implicitdeclarationoffunction

10、'nd_set_link'1 'structfile'hasnomembernamed'f_dentry'第一個是由于新內(nèi)核的lie結(jié)構(gòu)體發(fā)生了變化，把dentry這個成員放到了path結(jié)構(gòu)體里，這里只要更改下就行.structfileunionstructllist_nodefu_llist;structrcu_headfu_rcuhead;f_u；structpathf_path;structpathstructvfsmount*mnt;structdentry*dentry;直接在yaffs_vfs.c里加上下列定義就行，或者全部替換#de

11、finef_dentryf_path.dentry#definef_vfsmntf_path.mnt2 "new_sync_read/write'undeclaredhere對于第2個問題是由于新內(nèi)核沒有"new_sync_read/write”這兩個導(dǎo)出函數(shù)了改成.read=_vfs_read,/new_sync_read.write=_vfs_write,/new_sync_write3 error:implicitdeclarationoffunction'nd_set_link'到linux官網(wǎng)查詢發(fā)現(xiàn)4.4.16內(nèi)核里已經(jīng)不用nd_set_

12、link這個函數(shù)了，因此要修改用到這個函數(shù)的地方.主要就是yaffs_follow_link這個函數(shù)啦,yaffs_follow_link的定義主要參考你的include/Linux/fs.h里的structinode_operations.follow_link來定義.以前的alias是保存在nd->saved_names里，現(xiàn)在這個成員已經(jīng)被刪除了，直接通過函數(shù)返回值返回，并且保存在*cookie中-1053,7+1062,11# if(YAFFS_NEW_FOLLOW_LINK=1)+#ifLINUX_VERSION_CODE<KERNEL_VERSION(4,4,16)st

24、typesfor'nval_del'，查看nval_del幾個函數(shù)，這里我看不出有什么類型沖突錯誤，網(wǎng)上搜了卡主要是第一個WARNING里引起的.在yaffs_nameval.h中，結(jié)構(gòu)體structyaffs_dev的定義出現(xiàn)在參數(shù)列表中，而在此之前沒有定義，這樣會導(dǎo)致函數(shù)不識別這個結(jié)構(gòu)體引發(fā)上面的錯誤，查詢了下structyaffs_dev在“yaffs_guts.h”中被定義,因止匕在yaffs_nameval.h文件中include下"yaffs_guts.h”就OK了thirdstep通過上兩個修改后可能還會遇到下面的兩個錯誤：error:unknownty
