It was right there in my mail:

By setting the LD_LIBRARY_PATH environment you tell the linker to look for
installed libraries in /usr/local/lib.  You need to do this in the same
terminal that you use to build openbsc. This is very general build knowledge
and I am starting to repeat myself -- please consult your favorite search
engine on LD_LIBRARY_PATH...

Anyway, you are getting an error that I don't see:

As I said before, the 'dev' is a struct ipaccess_unit*, and it should
definitely not be an icomplete type. If the file were missing, the compiler
would complain.

You could verify that your osmocom/gsm/ipa.h file includes the definition of
struct ipaccess_unit like this:

struct ipaccess_unit {
        uint16_t site_id;
        uint16_t bts_id;
        uint16_t trx_id;
        char *unit_name;
        char *equipvers;
        char *swversion;
        uint8_t mac_addr[6];
        char *location1;
        char *location2;
        char *serno;
};

Check both in your git clone and what it looks like in
/usr/local/include/osmocom/gsm/ipa.h.

I can't think of any reason why it shouldn't be there if you have indeed
checked out the newest osmocom without local modifications, except maybe that
your disk is full and the header files cannot be written to disk?

Another way to fix this issue might be to 'make uninstall' and rebuild from
scratch, this time with each ./configure adding a prefix arg,
and use root privileges for the install step:

  ./configure --prefix=/usr [...]
  make
  make check
  sudo make install

This way things get installed in /usr and no special measures for /usr/local
should be needed.

In any case, this is all I can do for you from over here. It seems to be a
general problem not related to osmocom specifically.

I hope to have provided enough leads for you to fix it ... it definitely works,
don't give up and let us know of your progress :)
