I think this should be on Solaris: TN5250_LIBS... -L/usr/local/lib -l5250 -lssl -lcrypto -lnsl -lsocket -lncurses -lglib-2.0 -lresolv but we have already discussed that.


I'm working on an autoconf test for that now.

Grr... rpl_malloc? That isn't even in the code! And a quick check for 'man rpl_malloc' on the only solaris box I have access to turns up nothing. Unfortunately, I can't compile anything on it :(

But it looks like debug.c is missing stdlib.h so maybe that explains it. As well, config.h contains a reference to rpl_malloc that occurs when for whatever reason autoconf thinks that we should be using a different function for malloc. The odd part is that malloc is used in other places but doesn't seem to be replaced with rpl_malloc.

Further review reveals that this is being done by autoconf. But why is malloc being #defined to rpl_malloc in debug.c but not elsewhere?

Anyway, I've added stdlib.h to debug.c. I can't see any reason why rpl_malloc is being used, but maybe this will fix it. Plus, I've added a check to ./configure that should find it -lresolv is needed and add it for you. I can't test any of this on solaris though :( Would you mind grabbing the tarball again and giving it another shot?

If configure adds -lresolv to the linked libraries correctly then I can patch tn5250 to do it as well.
