I have been having problems running the unpack() loadable C function
in the IPL.

(Note: this is different from the unpack() that is in the packunpk.icn
module, which would not solve my problem.)

The issue is that I am trying to read a file of doubles in binary.
It seems unpack() is the only way.

What happens is that iconx prints a runtime error:

  /usr/local/bin/iconx: relocation error:
   /usr/local/bin/libcfunc.so: undefined symbol: cnv_str

Which tells me that I linked cfunc and path-ed the shared library
successfully, but still something (cnv_str) is missing.  Re-making
libcfunc.so does not help.

I'm using the Linux Unicon tar distribution that installs into
/usr/local/unicon, not the RPM.

Up until now, I have been using a little C program that reads the binary file and
prints the numbers in e-format, which Unicon can then read. I'd like to skip
this intermediate step, because it is exceeding the 2GB file size, and try
reading the binary numbers directly into Unicon.


Any suggestions? Has anybody tried this?
