[Cppcms-users] error while linking hello_world.fcgi

[Francesco A. <ke...@gm...>]

Hi all,

I'm new to the list. During compilation I have found a problem and resolved
with a simple change. I don't know the reason and I want to share with you
this problem hoping that it could be useful in future.

The error is shown during 'make' phase and regards compilation of
hello_world.fcgi. Below [1] is reported the error output. It seems that it
doesn't find libraries and probably it is necessary a little change in
Makefile.in file.

I have resolved the problem changing the following Makefile variable as
reported here:
hello_world_fcgi_LDADD = libcppcms.la transtext/libcppcmstranstext.la/usr/lib/
libcgicc.la /usr/lib/libfcgi++.la /usr/lib/libboost_signals-mt.so
 /usr/lib/libboost_system-mt.so /usr/lib/libdl.so
/usr/lib/libboost_regex-mt.so

I have Ubuntu 9.10 and all the libraries suggested in tutorial. Libtool
version is 2.2.6.

Hoping that this could be useful...

P.S.: Idea beyond CppCMS look great!
