Package zbuffer on 64-bit Ubuntu does not run "out-of-the-box" (for me
it doesn't).
1. Need to change line 19 of zbuffer.ijs to:
libf=. libp{:: 'zlibapi'; 'libzlib'; 'zlibwapi';''
libf=. libp{:: 'zlibapi64'; 'libzlib'; 'zlibwapi';''
however....
2. The library shipped does not contain the uncompress function:
m...@mb-laptop:~/j64-602/addons/arc/zip/lib$ nm zlibapi.so | grep uncomp
m...@mb-laptop:~/j64-602/addons/arc/zip/lib$ nm zlibapi64.so | grep uncomp
m...@mb-laptop:~/j64-602/addons/arc/zip/lib$ nm /usr/local/lib/libz.so |
grep uncomp
0000000000004b90 T uncompress
Therefore I change line 21 of zbuffer.ijs to:
LIB=: jpath ADDONDIR,'lib/',libf,'.',libe
LIB =: '/usr/local/lib/libz.so'
And the following works:
load 'arc/zip/zbuffer'
comp =: 3!:1@(#;zput)@(3!:1) : ( c...@] (1!:2) [) NB.
compress anything.
ucomp =: 3!:2@(0&{:: zget (1&{::))@(3!:2)`(ucomp@(1!:1))@.(32&=@(3!:0))
ucomp comp i.10
0 1 2 3 4 5 6 7 8 9
I do not understand why "libz" and "zlib" are used interchangeably but
they appear to be meant to be the same thing.
Does anybody else with 64-bit Linux have this problem?
