A collection of Fortran 2018 interface bindings to the OpenLDAP Lightning Memory-Mapped Database (LMDB), a B-tree-based database management library modeled loosely on the BerkeleyDB API.
The LMDB package has to be installed with development headers. On FreeBSD, run:
# pkg install databases/lmdb
On Linux, instead:
# apt-get install liblmdb-dev
If GNU Fortran is used to build the interface library, select the build target depending on your operating system. On FreeBSD:
$ make freebsd
On Linux, instead:
$ make linux
On Windows:
$ make windows
Or, overwrite the argument PPFLAGS. Install the library and the module files
system-wide, for example:
$ make install PREFIX=/opt
Link your programs against /opt/lib/libfortran-lmdb.a -llmdb. Alternatively,
overwrite the default compiler and the compiler/preprocessor flags:
$ make FC=ifx FFLAGS="-O3" PPFLAGS="-D__linux__"
Build and run the test program:
$ make test
$ ./test_lmdb
Pass the operating system as an additional flag to the Fortran Package Manager. On FreeBSD:
$ fpm build --profile release --flag "-D__FreeBSD__"
On Linux:
$ fpm build --profile release --flag "-D__linux__"
On Windows:
$ fpm build --profile release --flag "-D_MSC_VER -D_WIN32"
You can add fortran-lmdb as an FPM dependency:
