Another Newbie question.

I am now trying to build the hdf5 package for a 32-bit target.

I can't seem to track down this error:

See `config.log' for more details

Use this clue. What do you see in config.log?

Location:
/afs/slac/g/lcls/package/linuxRT/buildroot-2014.11/buildroot-uclibc-x86/output/build/hdf5-1.8.14/config.log

Yes, I found this in there:
uclibc/sysroot/usr/lib/crt1.o:<http://slac.stanford.edu/g/lcls/vol9/package/linuxRT/buildroot-2014.11/host/linux-x86_64/i686-linux/usr/i686-buildroot-linux-uclibc/sysroot/usr/lib/crt1.o:>undefined reference to symbol '__uClibc_main'

I can't understand why this happening.  Must be something in my environment ?

Meanwhile, I logged into a different 64-bit build host; all is well
I'm back in business :)

However, I will come back to try and solve this mystery

Cheers
Ernesto

Thanks in advance for any guidance.
