Alexandre,
The symbol cri_initialize_checkpoint_args_t existed in BLCR-0.6.X, but has not
existed since 0.7.0 was released in May 2008. In 0.6.X, it only appears in
the following extract from libcr.h, which was intended to convey that one
calls cr_initialize_checkpoint_args_t() and never uses
cri_initialize_checkpoint_args_t() directly. Note the cr_ vs. cri_ prefixes
are easy to get confused by mistake. The comment is out of sync with the name
of the function one is supposed to call, so I can see how confusion could result.

So, I see two possibilities. One is that you are using an old libcr.h header.
That is certainly possible if 0.6.X was installed, for instance, in
/usr/include or /usr/local/include. Another possibility is that your code is
calling cri_initialize_checkpoint_args_t() directly where
cr_initialize_checkpoint_args_t() was intended.
If you still need more help, let us know.
