libtermcap.so.2: cannot open shared object file: No such file or directory


Running a program get this error.

# ch
ch: error while loading shared libraries: libtermcap.so.2: cannot open shared object file: No such file or directory

However, libtermcap.so.2 is present.
# ls -l /lib/libtermcap*
lrwxrwxrwx 1 root root 19 Aug 12 10:03 /lib/libtermcap.so -> libtermcap.so.2.0.8
lrwxrwxrwx 1 root root 19 Aug 4 13:48 /lib/libtermcap.so.2 -> libtermcap.so.2.0.8
-rwxr-xr-x 1 root root 15320 Aug 12 10:03 /lib/libtermcap.so.2.0.8

I tried linking libtermcap.so.2 with libncurses.so.5, but still
doesn't work.

Linux version 2.6.7-gentoo-r11 (root@rose) (gcc version 3.4.1 (Gentoo
Linux 3.4.1, ssp-3.4-2, pie-8.7.6.3)) amd64

use ldd to make sure the program is not looking for the library in the wrong place.
if it is looking in the wrong place, add a symbolic link to fix it.

ldd /bin/ch
libtermcap.so.2 => not found
libm.so.6 => /lib32/libm.so.6 (0x5557c000)
libc.so.6 => /lib32/libc.so.6 (0x5559d000)
libdl.so.2 => /lib32/libdl.so.2 (0x556b4000)
libcrypt.so.1 => /lib32/libcrypt.so.1 (0x556b8000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x55555000)

libtermcap.so.2 is in the same /lib directory as /ld-linux.so.2.
Why ld-linux.so.2 is found but not libtermcap.so.2?

hmm.... okay, time to go overkill....

strace -o error.log /path/to/ch
cat error.log | grep libtermcap.so.2

this will print a list of actual paths,
its notmal to see lots of attempted opens but atleast one should be in the right place.
again, if non of the atempts are in the right place, fix with a symbolic link.

as for ldconfig, i may be wrong, but i think ldconfig is only used to locate library's when you are compiling from source, im assuning you installed this program from a binary rpm or somthing similar.

# strace -o error.log /bin/ch
[ Process PID=11358 runs in 32 bit mode. ]
/bin/ch: error while loading shared libraries: libtermcap.so.2: cannot open shared object file: No such file or directory

# cat error.log
execve("/bin/ch", ["/bin/ch"], [/* 41 vars */]) = 0


My linux is 64bit AMD64 gentoo.
It seems that /bin/ch is running in 32 bit mode.
How to fix this probem?

Hello, I know this is an ancient thread, but it came up in a google search and I wanted to let qwijibow know that his ldd suggestion helped me big time. I have been looking for some kind of utility like that and didn't realize it was standard. Thanks!

strace helped

Hi, I also know this is a very old thread. But just wanted to thank you for the strace command which helped in solving my issue.

In my case, the executable was checking for the library in the /usr/lib where as the private libraries were in a different path. Right now I created a link in /usr/lib to check if its working.

The path where the libraries are present is present in the LD_LIBRARY_PATH, dont know why its not taking it.

Anyways, thank you guys.

regards,
Ahamed.

I agree with @impala454 and @ahamed101:
these two commands "ldd" and "strace" are really useful!
Thank you @qwijibow!

I did something like:
Code:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/some/lib/directory/containing/the/so/file
I re-ran the program and it worked.

Best regards,
