Re: Linking on AIX

[John Ling <jling@bioinformatics.ubc.ca>]

Ok having attempted to build both static and shared was the problem.  I 
opted to build only static by configuring with --disable-shared and so I 
believe it build the static version of the library.  Now when I do an 
'ar tv' on my static library I get nothing returned.  Is this normal?

Unfortunately, when I try to compile using this library I get the following:

g++ -g -O2 -o bin/ac2gi atlas/cpp/src/apps/ac2gi.o 
lib/.libs/libseqget.a /usr/local/mysql/lib/libmysqlclient.a 
/flash/home/jling/install/lib/libubic.a -lz
collect2: /flash/home/jling/install/lib/libubic.a: not a COFF file
make: *** [bin/ac2gi] Error 1

What does it take to get that library into COFF format?

Thank You,
John Ling
