Re: [Nel] nelns build problems: NeL Misc

[David Castro]

The undefined reference is what is causing the problem.  I have the same 
issue when trying to manually link the libnelmisc.so.  g++ (not gcc) is 
being used, so that shouldn't be the problem.  Here is the relevant section:

configure:10918: checking for main in -lnelmisc
configure:10942: g++ -o conftest -g -O3 -DNL_RELEASE_DEBUG   
-I/usr/include/mysql -march=pentium4 -fomit-frame-pointer

-lcrypt  -L/usr/lib/mysql -lmysqlclient -lz -lcrypt -lnsl -lm -L/usr/lib 
-lssl -lcrypto >&5
