There are no 32-bit pre-built Clang binaries available on Linux. Since you have installed the latest version of Clang, you should run the install.py script with the --system-libclang flag:

./install.py --clang-completer --system-libclang

[Jianghui-Wang]

Yes, it works ! , but seemed there is sth else wrong.

when I open my vim a red line in the bottom say sth wrong and ask me to read ycmtogglelogs

I opened it , following is what he said:

---

2018-03-26 08:20:29,959 - ERROR - libclang.so.7: cannot open shared object file: No such file or directory
Traceback (most recent call last):

---

I can use $clang a.c to compile my c code, and I do not know where is wrong

Also when I use command "whereis libclang.so.7" it can show

---

➜ / whereis libclang.so.7
libclang.so: /usr/local/lib/libclang.so /usr/local/lib/libclang.so.7

---

[micbou]

What's the output of the commands:

ls /home/chw/.vim/plugged/YouCompleteMe/third_party/ycmd/

and

ldd /home/chw/.vim/plugged/YouCompleteMe/third_party/ycmd/ycm_core.so

?

[Jianghui-Wang]

[micbou]

Sorry, I should've asked you to list the files with -l:

ls -l /home/chw/.vim/plugged/YouCompleteMe/third_party/ycmd/

Also, does it work if you start Vim like this:

LD_LIBRARY_PATH=/usr/local/lib vim

?

[bstaletic]

It should work with LD_LIBRARY_PATH=/path/to/ycmd vim.

[Jianghui-Wang]

Yes! LD_LIBRARY_PATH=/usr/local/lib vim is useful ! (Although I do not know why

So, should I make a .sh to make sure it will works every time I open vim ?

[micbou]

I suppose there are dependencies of libclang.so.7.0 in /usr/local/lib. You can confirm that with:

ldd /home/chw/.vim/plugged/YouCompleteMe/third_party/ycmd/libclang.so.7.0

and

LD_LIBRARY_PATH=/usr/local/lib ldd /home/chw/.vim/plugged/YouCompleteMe/third_party/ycmd/libclang.so.7.0

The missing dependencies would be the ones not found in the first command but found in the second.

So, should I make a .sh to make sure it will works every time I open vim ?

There are several ways to permanently add /usr/local/lib to your library path. You can add the following line to your .bashrc:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

or you can create a file in the /etc/ld.so.conf.d folder that contains the line:

/usr/local/lib

then run ldconfig to update the library paths.

[micbou]

Nevermind, you don't need to create a file in /etc/ld.so.conf.d. There is already one containing /usr/local/lib (/etc/ld.so.conf.d/libc.conf). You just need to run ldconfig as root.

[Jianghui-Wang]

ThX! You really helped me, Thank you for your patient guidance.

However, the two seems the same ?

What's more, maybe "How to install ycm in 32bit linux" can add to README I suggest?

It is pretty hard to deal with in 32bit machine, while easily installed in my OS X.

LOL, I have never used this plug before and I hope I can enjoy it !

Strange. Not sure what's happening then.

What's more, maybe "How to install ycm in 32bit linux" can add to README I suggest?

Running a 32-bit Linux is rather uncommon so I think the wiki would be a better place to add such instructions.

If you have any questions, feel free to ask them in the Gitter room or on the ycm-users Google group.
