OpenSSL: PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: TRUSTED CERTIFICATE

Question

I need a hash-name for file for posting in Stunnel's CApath directory. I have got some certs in this directory and they are working well. Also, I have a server sert and server key:

cert = c:\Program Files (x86)\stunnel\server_cert.pem 
key = c:\Program> Files (x86)\stunnel\private\server_key.pem

When I try to calculate a hash of my new cert, I get an error:

/etc/pki/tls/misc/c_hash cert.pem

unable to load certificate 140603809879880:error:0906D06C:PEM
routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: TRUSTED CERTIFICATE

As I understand I must sign my cert, but I don't understand how I can do that. Please, provide the solution.

P.S.:

The message

unable to load certificate 140603809879880:error:0906D06C:PEM
routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: TRUSTED CERTIFICATE:

posted when I made c_hash for cert.pem This is not server_cert.pem, this is Root_CA and it is content something like

-----BEGIN CERTIFICATE-----  
...6UXBNSDVg5rSx60=.. 

-----END CERTIFICATE-----

When I write

openssl x509 -noout -text -in cert.pem

In console panel I see this info:

1. Since you are on Windows, make sure that your certificate in Windows "compatible", most importantly that it doesn't have ^M in the end of each line

   If you open it it will look like this:

   -----BEGIN CERTIFICATE-----^M
   MIIDITCCAoqgAwIBAgIQL9+89q6RUm0PmqPfQDQ+mjANBgkqhkiG9w0BAQUFADBM^M
   

   To solve "this" open it with Write or Notepad++ and have it convert it to Windows "style"

2. Try to run openssl x509 -text -inform DER -in server_cert.pem and see what the output is, it is unlikely that a private/secret key would be untrusted, trust only is needed if you exported the key from a keystore, did you?
