For example, how can I list available GDAL library versions ?
They are not listed on VCPKG packages website neither by vcpkg search gdalcommand.
Try this! it is a quick fix until vcpkg supports pkgs version listing. https://github.com/hamaney/vcpkg_version_finder.
on a related note:
to look up a package by name and get the latest available version of it use vcpkg search <pkg name>
UPDATE SEP-11-2021:
I just found out that you can use the experimental flag x-history. for example vcpkg x-history <pkg name> (you might need an internet connection the first time you run this command).
You can use https://vcpkg.link/ in order to find all the versions of a package and when it got released (e.g. https://vcpkg.link/ports/gdal/versions for gdal). Besides, you can also see from which version a given feature has been introduced by looking at the overview of a package.

is there possibility how to install older version of packages by using vcpkg install?
I found that there is a file in versions/baseline.json, but even if I change the version of the package there, it always install the newest one.
Maybe https://github.com/microsoft/vcpkg/blob/master/docs/specifications/versioning.md is what you are looking for. Be aware you need to pass an additional flag to vcpkg to activate that feature. It also only works in manifest mode and not in classic mode.
How does one completely remove vcpkg and all installations/system changes made by it?
I recall seeing some FAQ about vcpkg where it said that you could just delete the vcpkg folder. However, I've been trying to find that same FAQ for over an hour now, to no avail. Also "just delete the folder" being the solution seems implausible to me, since I would assume vcpkg changes some environment variables or other settings, as well as the integration with Visual Studio that I was trying to use. Online search on this topic only yielded people discussing how to remove multiple installed libraries at once, with no clear solution even to that problem (I would be interested in this as well). The vcpkg website itself seems to offer no answers to this question.
edit: I found the page saying "just delete the folder" at docs.microsoft.
The documentation page https://learn.microsoft.com/en-us/cpp/build/vcpkg offers the instruction how to uninstall:
Uninstall vcpkg
Just delete the directory.
It could also mention that removing the vcpkg directory completely actually uninstalls all the installed libraries (all ports), because the vcpkg directory is the sole place where vcpkg.exe deploys any files.
Additionally, if you did run vcpkg integrate install, then you may also run vcpkg integrate remove to remove the user-wide (global) integration.

I like to have a local copy of the ocaml reference manual that correspond to the current version I'm using, so I used to build the documentation when I was compiling ocaml from source.
Now that I use opam, I was wondering if it was possible to ask it to build the documentation when I create a new switch.
Not directly, but you can install a matching version of the manual with
opam install ocaml-manual
You can get the reference manual and documentation for all installed packages via the odig utility,
opam install ocaml-manual odig odoc #installs necessary packages
odig odoc # builds the documentation (takes a while)
odig doc # opens the built documentation in your browser
You can also use odig to search for packages and otherwise explore your opam installation.
I just downloaded biicode and tried to follow the getting started instructions but received an error about the Cmake 3.0 or higher being required.
However, ubuntu 14.4 uses "cmake version 2.8.12.2"
Is there a way to use biicode with 2.8 or am I stuck installing the newer version of CMake?
TIA!
No, biicode requires cmake > 3.0. There is a setup command that helps installing it:
$ bii setup:cpp
This will install CMake >3.0 in /home/user/biicode_env, and add it to the path, so it doesnt interfere/overwrite your current 2.8 installation. Biicode needs that executing "cmake" in the console actually uses 3.0, so it should be first in the path. You can manage it very easily in two different ways, with a symbolic link (/usr/bin) that you redirect as needed or adding/removing an entry in the path before executing biicode.
This is a different thing, but I woiuld like to say that I have migrated existing projects from cmake 2.8 to 3.0 without any problems, and 3.0 runs great and has useful new features. So I would recommend regular cmake users to upgrade if possible.
No, there isn't any way to change this requirement because internal biicode CMake has features, like the use of INTERFACE libraries, which are only available on CMake 3.0 or later. However, don't worry about upgrading CMake version, this one always keeps a exhaustive compatibility with older versions ;)
I would like to install a specific version of gdb and gcc with macports on mac os x leopard, not the last one, but the 6.8 for gdb. Is it possible?
It is possible. It's just convoluted and tedious. It's listed in the documentation these days.
Steps
Go to macports trac and find the package you're looking for. This is the link for subversion, which is the package I'll be using in the example.
Click the PortFile
Click Revision Log (top right)
Pour through the revisions until you find the version you're looking for. Remember the revision number.
In this example I'm looking for version 1.7 of subversion.
With that revision number noted. You need to checkout the version of that subdirectory at that revision.
cd /tmp
svn co http://svn.macports.org/repository/macports/trunk/dports/devel/subversion --revision 106629
Then cd into the folder and run the install
cd subversion
sudo port install
Then it should become selected by default. You can check with
sudo port installed subversion
The following ports are currently installed:
subversion #1.7.10_0 (active)
subversion #1.8.8_0
subversion #1.8.10_0
As I just came across this question when trying to figure out how to download an older version of curl, I thought I'd share an update:
The currently accepted answer did not work for me any longer. This is with MacPorts 2.2.0. What I did was the following.
I started following the directions located here. I ended up using the SVN method, since the first method didn't work. What I didn't realize is that I was missing a critical step.
I found another post that suggested moving the downloaded directory to /private/tmp. After doing this, I cd into the new directory and after a sudo port install I was able to install the older version.
I am on a Mac running OS X 10.8, so your mileage may vary.
This post is old.. but specifying a version is possible. For example I want to install ZeroMQ version 3.2.2 so I use:
sudo port install zmq #3.2.2
And it always helps to goto the MacPorts website and search to see if they have what you are looking for.
As far as I know it is not possible at all to install other versions than the exact version, unless there is a specific port for a certain version.
The only thing you could do is fetch the portfile of the desired version from the Macports subversion repository.
In your case only gdb 7.2 is available on the current version, no variants and no other versions - sorry :)
