I'm trying to compile GNU Source highlight in my home directory.
I configured with a prefix and --with-boost=/path/to/boost/root/dir/ and no errors were reported.
But when I try to build I got the following error:
$ make
... # lots of output

/usr/bin/ld: cannot find -lboost_regex
collect2: ld returned 1 exit status
Note that, I have Boost loaded in my environment, in fact:
$ echo $LD_LIBRARY_PATH
/path/to/boost/root/dir/lib:/other/path/lib
and ls shows that /path/to/boost/root/dir/lib/libboost_regex.so exists and is a symbolic link to libboost_regex.so.1.47.0
How is this possible? How can I solve it?
At linking time, the correct environment variable to use to define the path where to find the libraries is LIBRARY_PATH, not LD_LIBRARY_PATH. The former is equivalent to specifying -L in the gcc arguments, while the latter is used at runtime, like PATH, to find the binary executables. See this for more information.
