x264 make problem

[VLC_help]

Did you even read the error?

Don't have the file or directory

Thank you, VLC_help!

Now I use "make" command to compile the ffmpeg, it generated the following error in the end:

ln: Create symbolic link “libavutil.so”: Operation not supported
make: *** [libavutil/libavutil.so] Error 1

How to enable it to support this "ln" operation and solve the problem,please?

Thank you in advance!

[VLC_help]

ln will fail if the file system doesn't support symbolic links. IIRC FAT and FAT32 don't support them.

Thank you very much, VLC_help!

Dear everyone,

I used mount command to see my file system type, and it generated the following information:

/dev/sda1 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw)
none on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type tmpfs (rw,mode=0755)
none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
none on /dev/shm type tmpfs (rw,nosuid,nodev)
none on /var/run type tmpfs (rw,nosuid,mode=0755)
none on /var/lock type tmpfs (rw,noexec,nosuid,nodev)
none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
.host:/ on /mnt/hgfs type vmhgfs (rw,ttl=1)
none on /proc/fs/vmblock/mountPoint type vmblock (rw)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
gvfs-fuse-daemon on /home/huoyi/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=huoyi)

from above I got the type of the file system is ext4. It isn't fat, why doesn't it support symbolic link? and how to enable it to support,please?

Thank you in advance!

Dear everyone,

I have solved the problem by moving the code to an unshared directory.

Now I want to add x264 lib to ffmpeg to enable ffmpeg to encode h264 format. First, I set up x264 through the following commands:
./configure --enable-shared
make
sudo make install
sudo ldconfig

Then I compiled ffmpeg as following:
./configure --enable-libx264 --enable-gpl --enable-shared
make

After I run make command, it generated the following error information in the end:
LD ffmpeg_g
/home/huoyi/public/x264_to_ffmpeg/ffmpeg/libavcodec/libavcodec.so: undefined reference to `x264_encoder_open_116'
collect2: ld returned 1 exit status
make: *** [ffmpeg_g] Error 1

How to solve the problem,please? Thank you in advance!
