install-dirs: a general directory installer
Copy installs non-binary (platform) directories.
Eg,
install-dirs -prefix=... -devel
install-dirs -prefix=... -default -no-app
----
install-platform: a platform (binary) installer
This is primarily driven by the need to install into system mpi
directories. The problem noted in issue #1893 is caused by the
rpm-mpi-hooks (fedora and redhat-8).
For the additional mpi library qualifier (openmpi-x86_64) to be
added to the requirements, the mpi-specific libraries (eg,
libPstream.so) need to be installed in the mpi system directory
(eg, /usr/lib64/openmpi).
However, then need symlinks from the system locations back to our
local directories to ensure that the libraries are correctly found
via our LD_LIBRARY_PATH and we don't get dummy libraries.
----
update-mpi-links: a post-install update hook
Expected paths are registered as persistent information into the
hook during packaging. Triggering the hook after installation
completes the creation of the symlinks.
Normal usage,
```
prefix="/tmp/local-install/openfoam"
bin/tools/install-dirs -prefix="$prefix" -common
bin/tools/install-platform -prefix="$prefix"
```
Installs
- /tmp/local-install/openfoam/META-INFO
- /tmp/local-install/openfoam/bin
- /tmp/local-install/openfoam/etc
- /tmp/local-install/openfoam/platforms/linux64GccDPInt32Opt/bin
- /tmp/local-install/openfoam/platforms/linux64GccDPInt32Opt/lib
Can also place architecture-dependent bits elsewhere,
```
prefix="/tmp/local-install/openfoam"
multi_arch="$(dpkg-architecture -qDEB_TARGET_MULTIARCH)"
bin/tools/install-dirs -prefix="$prefix" -common
bin/tools/install-platform -exec-prefix="$prefix/$multi_arch"
```
Installs
- /tmp/local-install/openfoam/META-INFO
- /tmp/local-install/openfoam/bin
- /tmp/local-install/openfoam/etc
- /tmp/local-install/openfoam/x86_64-linux-gnu/bin
- /tmp/local-install/openfoam/x86_64-linux-gnu/lib
Can use it to flatten out platforms entirely,
```
prefix="/tmp/local-install/openfoam"
bin/tools/install-dirs -prefix="$prefix" -common
bin/tools/install-platform -exec-prefix="$prefix"
```
