Anyone have any idea what's the matter?
Search in config.log for db_create; you should see the exact C program Autoconf is testing with, the compiler invocation, and the errors.
If your db library is in /usr/lib or /lib, this won't apply, but I'll vent anyway: My experience is that autoconf not finding libraries is often because of shared libraries. That is, the program has to be linked with -R/your/library/dir. This is true even for libstdc++, libgcc_s, and the like. I have never understood why GCC does not automatically -R those directories. (I reported it, but they rejected the suggestion.) The result is that if you compile a hello,world C++ program, it will not run if the libstdc++ used is not in a system directory.
In the latest gcc, they made it even harder by (apparently) removing -R as an option to the compiler. To configure subversion, for example, I had to resort to this: configure \ --with-berkeley-db=/usr/local/db \ LDFLAGS="-Wl,-R -Wl,/usr/local/db/lib -Wl,-R -Wl,/usr/local/gnu/lib -Wl,-R -Wl,/usr/local/lib" \
Sigh.
Happy linking, karl
