Having successfully installed opam and having switched to 4.01.0 version of compiler I am struggling to install utop. Installation is failing at 'conf-ncurses.1' step.
Running 'opam depext' does not reveal much, saying that 'no extra dependencies' need to be installed. Switching to latest stable compiler, and then installing utop fails with the same problem. The *.err and *.out files are empty, hence not revealing any problem.
On my box I also have ncurses-devl and pkgconfig installed (see rpm output below)
Below is the screenshot of what I can see (hopefully it give us enough information). Any ideas where to look at ?:

First of all, SO is not an issue tracker and it is better to report this issue to the package maintainers. The following command will reveal URLs for the issue trackers:
opam show conf-ncurses | grep bug-reports
opam show utop | grep bug-reports
Second, your output is not at sync with what I'm seeing in the opam-repository. At the current HEAD there is no check pkg-config ncurses at all, as it was removed three days ago. So, if you indeed have ncurses-devel package installed, then you need just to update opam, with
opam update

I'm doing some works with ocaml and opam.
I need ocaml of version 3.08.3, so I tried install this version via opam.
opam switch install 3.08.3
The above command would install it successfully, I hoped. But it couldn't.
opam-switch could not install 3.* versions of ocaml with the following error message.
[ERROR] Could not resolve set of base packages
I searched this message everywhere, but I couldn't get any of hints. Does anyeone have a clue to solve this problem? Thanks.
compilers/3.08.3/3.08.3/3.08.3.comp, the file to describe the base packages for that compiler version tells:
packages: [
"base-unix"
"base-bigarray"
"base-threads"
"base-ocamlbuild"
]
So it requires base-unix, base-bigarray, base-threads and base-ocamlbuild. However, the package description of base-ocamlbuild, packages/base-ocamlbuild/base-ocamlbuild.base/opam says:
ocaml-version: [>= "3.10" & < "4.03"]
It says that ocamlbuild is not available before 3.10. Indeed, ocamlbuild was introduced since 3.10. It is likely that the compiler description file 3.08.3.comp has a bug. It is great if you would raise a bug ticket at https://github.com/ocaml/opam-repository/issues for the fix.
For a workaround, I recommend to install OCaml 3.08 by hand, not using OPAM command: I see almost no benefit to use OPAM with 3.08 where ocamlbuild is not available, since most of the OPAM packages assume the existence of ocamlbuild.
You could also create your own copy of OPAM repo with a fixed 3.08.3.comp file without "base-ocamlbuild". See the document of opam repo for more details.
I'm trying to install Janestreet's Core for OCaml using opam on Mac OsX to get started with the "Real world OCaml" book.
I get the following error:
===== ERROR while installing herelib.109.35.02 =====
Could not get the source for herelib.109.35.02:
# opam-version 1.1.1
# os darwin
Cannot download https://opam.ocaml.org/archives/herelib.109.35.02+opam.tar.gz,
please check your connection settings.
All other libraries after herelib fail as well.
I don't have connection problems, though, as the libraries up to herelib do download (last successful is type_conv as far as I can tell). Also, pasting the reported URL in Chrome starts a file download immediately, so it doesn't seem to be a server problem at the source.
Homebrew reports my Opam and Ocaml as up to date.
Any ideas?
Your version numbers for both herelib and opam looks quite outdated. The following may help:
Update your repository with opam update
Try to use more recent opam, it is available under macports and brew.
I just installed opam using the quick install
http://opam.ocaml.org/doc/Quick_Install.html
I now have
$opam --version
1.1.0
which is current. I ran "opam update" and "opam upgrade" to get the latest packages. However, when I install packages, it is still giving me the old versions (such as core 109.42 instead of core 109.55):
$ opam search core
Available packages for 4.01.0:
async_core 109.42.00 Monadic concurrency library
What do I need to do to get opam to give me the latest libraries?
If you previously built from source, make sure you uninstall that first. For whatever reason, even though the opam version correctly reports "1.1.0", it was still using the old repo address. After you uninstall old opam entirely, then follow the installation instructions at the link above.
You will know you succeeded when you do "opam update" and prints:
default Downloading http://opam.ocamlpro.com/urls.txt
[NOTE] The repository 'default' will be *permanently* redirected to https://opam.ocaml.org (opam-version >= "1.1.0")
I am tearing my hair out trying to install Spatialite for GeoDjango!
I am already using Homebrew, it's generally easy and convenient so I initially tried to follow the Homebrew instructions for GeoDjango.
But this stops short of installing any database, i.e. Spatialite. The next step is to try and install Spatialite itself, but there are no Homebrew-specific instructions provided by Django docs.
I found this tutorial which looks perfect - a Homebrew and virtualenv-friendly install of Spatialite for GeoDjango.
But it doesn't work... it appears that my pysqlite is linked against the non-spatial-enabled version of SQLite that comes with OS X, rather than the Spatial-ised one I installed from Homebrew, I get this error when Django tried to connect to the db:
"The pysqlite library does not support C extension loading. Both SQLite and pysqlite must be configured to allow the loading of extensions to use SpatiaLite."
The author of pysqlite hasn't responded to my pleas for help on Github and I haven't found anything via Google.
So I went back to the drawing board and decided to follow the "Mac OS X-specific instructions" in the GeoDjango docs... by installing the various geo libs from the KyngChaos binary packages.
The docs say "Install the packages in the order they are listed above" but I found I couldn't install UnixImageIO without installing PROJ first. The link in the docs to download Spatialite binaries (http://www.gaia-gis.it/spatialite-2.3.1/binaries.html) is broken so I used the "Spatialite Tools v4.1" from KyngChaos instead.
Proceeding to the next step I get this error:
$ spatialite geodjango.db "SELECT InitSpatialMetaData();"
SQLite header and source version mismatch
2013-10-17 12:57:35 c78be6d786c19073b3a6730dfe3fb1be54f5657a
2013-09-03 17:11:13 7dd4968f235d6e1ca9547cda9cf3bd570e1609ef
Not really sure what's wrong at this point.
There is someone else here on SO who has gone the KyngChaos route and just ends up with the same "Both SQLite and pysqlite must be configured to allow the loading of extensions" error I got from the Homebrew route anyway.
I found this ticket #17756 for adding pyspatialite support to Django - pyspatialite is supposed to be an easier way to pip install everything but unfortunately it doesn't work either (see comments towards bottom of ticket).
I'm a bit reluctant to start trying to build everything from source by hand as it seems likely I'll just run into the same problems again, but spending hours Googling for info about cryptic compiler errors, magic flags and paths etc along the way.
I'm about ready to give up and just use Postgres/PostGIS.
I was able to get this working now, using the tip here:
https://github.com/ghaering/pysqlite/issues/60#issuecomment-50345210
I'm not sure if it was using the real paths that fixed it, or just the Homebrew kegs or underlying packages have been updated and now install cleanly. Still, it works now.
I reproduce below the steps I took:
brew update
brew install sqlite # 3.8.5
brew install libspatialite # 4.2.0
brew install spatialite-tools # 4.1.1
git clone https://github.com/ghaering/pysqlite.git
cd pysqlite
(where brew reported I had existing versions I unlinked them and installed the latest as commented above)
then edited setup.cfg to comment out #define=SQLITE_OMIT_LOAD_EXTENSION and specify the paths:
include_dirs=/usr/local/opt/sqlite/include
library_dirs=/usr/local/opt/sqlite/lib
activated the virtualenv where I want it installed, then
python setup.py build
python setup.py install
(build_static still fails with clang: error: no such file or directory: 'sqlite3.c')
(maybe I should have done pip install . as suggested in the github issue)
now the spatialite geodjango.db "SELECT InitSpatialMetaData();" succeeds, albeit with an ignorable error:
InitSpatiaMetaData() error:"table spatial_ref_sys already exists"
i.e. it's probably not even necessary to run that command
When I was istalling this i follow this instructions https://docs.djangoproject.com/en/dev/ref/contrib/gis/install/spatialite/#pysqlite2
pysqlite2
If you’ve decided to use a newer version of pysqlite2 instead of the sqlite3 Python stdlib module, then you need to make sure it can load external extensions (i.e. the required enable_load_extension method is available so SpatiaLite can be loaded).
This might involve building it yourself. For this, download pysqlite2 2.6, and untar:
$ wget https://pypi.python.org/packages/source/p/pysqlite/pysqlite-2.6.3.tar.gz
$ tar xzf pysqlite-2.6.3.tar.gz
$ cd pysqlite-2.6.3
Next, use a text editor (e.g., emacs or vi) to edit the setup.cfg file to look like the following:
[build_ext]
#define=
include_dirs=/usr/local/include
library_dirs=/usr/local/lib
libraries=sqlite3
#define=SQLITE_OMIT_LOAD_EXTENSION
I had the same error: SQLite header and source version mismatch.
For me it was enough to update libsqlite3-dev.
After that invoking $ spatialite geo.db "SELECT InitSpatialMetaData();" creates proper database.
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 :)
