Isn't the above necessary so that it searches for the libboost_regex.so link in that directory, which would make it build at compile time against libboost.so.1.35.0 in my case? (Well, that's what I expected, but it clearly does not do that here when using gcc 4.2 or 4.3) >> $ echo $LD_LIBRARY_PATH >> /cvos/shared/apps/gcc/gcc-4.2.4//lib:/cvos/shared/apps/boost/ gcc-4.2/1.35.0/lib:/cvos/shared/apps/sge/6.1/lib/lx26-amd64 > This should work, though. >> $ g++ -o test test.cpp -lboost_regex > > Use `gcc -v' here. Let's see what that says. $ gcc -v -o test test.cpp -lboost_regex Using built-in specs.
