[antlr-interest] C runtime linking error?

[Yves Weißig]

Hi,

sorry to bump this topic, but my problem is still present.
I re-isntalled the antlr3.4c runtime and re-generated the C-files and
have still no luck, even this compilation fails with the "undefined
reference" errors:
gcc -lantlr3c -I../src ../src/RtfLexer.cpp ../src/RtfParser.cpp
So even stripping it down to C and without my custom code I run into the
same problems.
The libraries are in the correct spot:
foo at bar:~$ ll /usr/local/lib/
total 304
drwxr-xr-x  3 root root    4096 2012-03-19 12:40 ./
drwxr-xr-x 10 root root    4096 2011-10-12 16:27 ../
-rw-r--r--  1 root root  154132 2012-03-19 12:40 libantlr3c.a
-rwxr-xr-x  1 root root     929 2012-03-19 12:40 libantlr3c.la*
-rwxr-xr-x  1 root root  136864 2012-03-19 12:40 libantlr3c.so*
drwxrwsr-x  4 root staff   4096 2011-10-12 16:27 python2.7/
I guess gcc and g++ find the library, otherwise they would throw an
error. What else maybe wrong? Am I missing some packages/dependencies?

Best regards
Yves
