Re: Problem Regarding ROHC Implementation
-
- Hi Didier,
- Thank you very much for the help. I updated my rohc version to 1.6.1
and followed the installation instructions that you recommended.
- Everything was fine and all the tests were ok. But now I've been
working in another problem related with the "Getting started" section (
http://rohc-lib.org/presentation/getting-started/).
-
- I created the rohc_hello_world.c file and followed the instructions
until the "Create one IPV4 packet" section.
-
- In the "Create a ROHC compressor" section (final part) a error appears
when I tried the comand gcc -o rohc_hello_world -Wall $(pkg-config rohc
--cflags --libs) \
- rohc_hello_world.c
-
- The error message is:
- /tmp/cclGeag1.o: In function `main':
- rohc_hello_world.c:(.text+0x50): undefined reference to
`rohc_alloc_compressor'
- rohc_hello_world.c:(.text+0x249): undefined reference to
`rohc_free_compressor'
- collect2: error: ld returned 1 exit status
-
- It seems that the link with the ROHC library isn't working. I got the
same error when I put the "gcc -o rohc_hello_world -Wall
rohc_hello_world.c".
-
- I'd like to know if anyone here already had the same problem.
- Thanks,
- Edvar

Version 1.3.1 is obsolete, I strongly advise you to update the ROHC
library to the latest stable version, ie. version 1.6.1

Did you extract the archive that contains the test captures? If not,
refer to step 5 in the installation
procedure:https://rohc-lib.org/support/wiki/doku.php?id=library-install-sources#native_build_on_unix-like_systems
The archives with test captures are available for download
here:https://rohc-lib.org/support/download/#supported-releases
