perl on pc 104

[Ron Eggler]

Hi,

I need to get perl5 on our little pc104 (with goede) system in order to get
ssh-keygen( openSSH) - which depends on openSSL which depends on perl5 -
running.
When I'm trying to compile (configure) it, I get this messages:

I used the command:

cc -o
try -O2 -fno-strict-aliasing -pipe -I/usr/local/include -L/usr/local/lib
try.c -lnsl -ldb -ldl -lm -lcrypt -lutil -lc
./try

and I got the following output:

/usr/lib/gcc/i586-linux-uclibc/3.4.4/../../../libdb.so: undefined reference
to `pthread_condattr_setpshared'
/usr/lib/gcc/i586-linux-uclibc/3.4.4/../../../libdb.so: undefined reference
to `pthread_mutexattr_destroy'
/usr/lib/gcc/i586-linux-uclibc/3.4.4/../../../libdb.so: undefined reference
to `pthread_mutexattr_setpshared'
/usr/lib/gcc/i586-linux-uclibc/3.4.4/../../../libdb.so: undefined reference
to `pthread_mutexattr_init'
/usr/lib/gcc/i586-linux-uclibc/3.4.4/../../../libdb.so: undefined reference
to `pthread_mutex_trylock'
collect2: ld returned 1 exit status
I can't compile the test program.
(The supplied flags or libraries might be incorrect.)

You have a BIG problem. Shall I abort Configure [y] y
Ok. Stopping Configure.
[root@NEMS perl-5.10.0]# find / -name "libdb.so"
/usr/lib/libdb.so


Any ideawhat I would be doing wrongly and what that exactly is, as you can
see, i made a find on the bottom and i do have the libdb.so available
in /usr/lib.

Thanks for any help!

Not libdb.so is your problem (you added it with -ldb already). libpthread.so
is missed. Add -lpthread to the list of libraries to link.
