[Shriram Agarwal]

Hi,

I get following error on RedHat 7.5.

which package/library do i need to install?


Thanks

Shri

You're probably not missing a package or library, the expTable variable
comes from the file b44ExpLogTable.h, which is generated by make via the
b44ExpLogTable program, which make compiles from the source file
b44ExpLogTable.cpp. Somehow that program must be failing to compile or run,
not sure what could be causing that.

Thanks Cary for responding.
I looked at source b44ExpLogTable.cpp file and it does not have logTable declared and b44ExpLogTable.h is empty.
I have already done make clean but still no luck.
I followed compilation direction as specified.

Here is commit id which I am using.

commit 0ac2ea34c8f3134148a5df4052e40f155b76f6fb

Author: Nick Rasmussen <***@ilm.com>

Added the nodist_ prefix to the config headers so the generated files aren't included

as part of the disted tarballs.


Thanks
Shri

The compilation fails due to Half.dll/.so not being in the same path as
the b44 executable.
