[GNUnet-developers] libextractor, macos x

[Jussi Eloranta]

Hi,

Couple of things I ran into with gnunet 0.6.1c:

1.

On GNU/Linux (Fedora) I get:

Resolving symbol 'libextractor_lower_extract' in library 
libextractor_lower failed, so I tried '_libextractor_lower_extract', 
but that failed also.  Errors are: /usr/lib/libltdl.so.3: undefined 
symbol: libextractor_lower_extract; and then: /usr/lib/libltdl.so.3: 
undefined symbol: _libextractor_lower_extract
Inserting test.dat (no description supplied, unknown) under keyword 
test.dat.

My guess is that the function name in libextractor (0.2.6) file
.../plugins/lowerextractor.c has wrong function name:

extract() should be libextractor_lower_extract() ? Or was this 
generated somehow automagically and this just did something
wrong?

2. On MacOS X (10.3.2 with gcc-3.3 from apple) the existing config stuf 
for extractor 0.2.6 did not
work for me. I had to modify the configure.ac file as follows:

case "$host_os" in
darwin*)
#    AM_CONDITIONAL(DARWIN_LIBTOOL_BROKEN,true)
#    AC_DEFINE([USE_NS_MODULE],1,[Determines if we should use the 
NSModule API for dynamic loading])
    AM_CONDITIONAL(DARWIN_LIBTOOL_BROKEN,false)
    LIBLTDL=/sw/lib/libltdl.a
    LTDLINCL=-I/sw/include
    ;;

[This requires libtool stuff installed under /sw, which is the default 
if one is
using Fink] Also maybe one should add a switch to configure which would 
allow
specification of libltdtl?

3. dictionary-builder.c in ... plugins/printable

dumps core. This seems to be due to the following line (isol. within 
!!!s):

  while (1 == fscanf(dictin, "%s", (char*)&line)) {
    words[cnt] = strdup(line);

!!!
    if (words[cnt][strlen(words[cnt]-1)] != '%')
!!!

      cnt++;

There were no % characters in the *.txt files so I just commented
the above line. Is the idea that % is a comment sign ?

BTW configure sets up the compilation for gcc-3.3 (from Apple).

4. On MacOS X there is no values.h header (which is btw obsolete anyway)

I believe that this should be replaced with limits.h and float.h
and correct symbols should be used? (well, it compiles with these two)

This reference occurs in 
GNUnet-0.6.1c/src/applications/afs/module/manager.c

I used the following configure line:

/configure --with-extractor=/usr/local --with-gdbm=/sw

(gdbm was installed from Fink) Also I believe that the compilation 
found libltdl from /sw (FInk again).

5. Weird dynamic linker problem on Macos X. It insisted that _gettext
could not be found when I start gnunetd. If force it to look for 
libintl.dylib
then it works, ie.:

setenv DYLD_INSERT_LIBRARIES /sw/lib/libintl.dylib
/usr/local/bin/gnunetd

It appears to be a problem for all gnunet-* binaries (so a quick hack
is to put the setenv in .cshrc or whateverRC).

This is probably a problem on my machine... but who knows...

6. Files download correctly but at the end of download (and 
occasionally during download) I get:

[comp56:~/gnunet-downloads] % gnunet-gtk
Mar  7 21:52:18 FAILURE: file corrupted (or bug), top crc mismatch in 
block 1 0: 7d9f6b4d != 25812b15 or 466dc92 != 466dc92
Mar  7 21:52:18 __BREAK__ at block.c:1825
Mar  7 21:52:18 top CRC mismatch!
Mar  7 21:52:18 __BREAK__ at logging.c:240

It calims CRC error but, in fact, there is no error in the downloaded
file.
