I wish to install ctypes on my Ubuntu 14.04 computer. I am trying to do so using opam but its failing. Here's the response that I get :-
opam install ctypes

`opam depext conf-ncurses.1' may help you find the correct installation for
your system.
The former state can be restored with:
opam switch import "~/.opam/4.03.0/backup/state-20160410155208.export"
There's still no text in the error files.
Thanks.
When you are dealing with such erros, you can get more detail by looking the whole errors in the error file pointed out by opam, which is here :
cat /home/ask/.opam/4.02.1/build/conf-ncurses.1/conf-ncurses-3089-ccabea.err
Please note that you also have classical output here :
cat /home/ask/.opam/4.02.1/build/conf-ncurses.1/conf-ncurses-3089-ccabea.out
You may have additional informations that will allow you to end your installation. Sometimes some deps are forgotten in the depext command.
PS : I write here because I don't have enough reputation to ask precision in comment
try the following:
$ apt-get install libncurses5-dev
$ pkg-config --print-provides ncurses
to verify that both ncurses and pkg-config are installed and working correctly.
further diagnostics:
$ dpkg-query -L libncurses5-dev | grep pc$
# results for my machine
/usr/lib/x86_64-linux-gnu/pkgconfig/form.pc
/usr/lib/x86_64-linux-gnu/pkgconfig/ncurses++.pc
/usr/lib/x86_64-linux-gnu/pkgconfig/panel.pc
/usr/lib/x86_64-linux-gnu/pkgconfig/ncurses.pc
/usr/lib/x86_64-linux-gnu/pkgconfig/menu.pc
$ pkg-config --variable pc_path pkg-config
# results for my machine
/usr/local/lib/x86_64-linux-gnu/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig
note that libncurses5-dev has installed its ncurses.pc file in a directory that is in pkg-config's default search path.
If that is not true for your system, try setting $PKG_CONFIG_PATH explicitly to point to where libncurses5-dev has installed ncurses.pc. (Also check that the file actually is there!)
This discussion may be helpful too: https://askubuntu.com/questions/210210/pkg-config-path-environment-variable/373217
In my system if I add
export PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig/
and then execute
opam install conf-ncurses
it works

While installing xorg with conan install .. command,
system requirements are checked in conan receipe using pkg-config tool.
Each missing system package raises an exception, and thus stop the conan install command.
ERROR: xorg/system: Error in package_info() method, line 97
self._fill_cppinfo_from_pkgconfig(name)
while calling '_fill_cppinfo_from_pkgconfig', line 24
if not pkg_config.provides:
ConanException: pkg-config command ['pkg-config', '--print-provides', 'xcb-renderutil', '--print-errors'] failed with error: Command 'pkg-config --print-provides xcb-renderutil --print-errors' returned non-zero exit status 1.
Package xcb-renderutil was not found in the pkg-config search path.
Perhaps you should add the directory containing `xcb-renderutil.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xcb-renderutil' found
I cannot get those system packages to be installed by conan tool, am I missing a command line argument while invoking conan ?
you can ask conan to install binary packages into your system ( sudo apt-get install ... ) by himself. See my example:
sudo conan install /home/username/QtProj/console_test1/QCoreApplication_quit_example/conanfile.txt --build=qt -c tools.system.package_manager:mode=install
To use it your conan version must be installed using sudo. If you get:
sudo: conan: command not found
You should do:
pip uninstall conan
sudo pip install conan
There are usually distribution-specific package manager warnings listing what dependencies need to be installed above this line:
ERROR: xorg/system:...
For example, on Ubuntu 22.04 I got the following after adding opencv/4.5.5 to my conanfile.txt:
...
dpkg-query: no packages found matching libx11-xcb-dev
dpkg-query: no packages found matching libfontenc-dev
dpkg-query: no packages found matching libxaw7-dev
dpkg-query: no packages found matching libxkbfile-dev
dpkg-query: no packages found matching libxmu-dev
dpkg-query: no packages found matching libxmuu-dev
...
ERROR: xorg/system:...
You can resolve this by installing the listed dependencies. In my case this is what solved it:
sudo apt-get install -y xorg openbox xauth libx11-xcb-dev libx11-xcb-dev libfontenc-dev libxaw7-dev libxkbfile-dev libxmu-dev libxmuu-dev libxpm-dev libxres-dev libxss-dev libxt-dev libxtst-dev libxv-dev libxvmc-dev libxxf86vm-dev

I have tried the following solutions, but none of them seem to work:
https://github.com/ocaml/graphics/issues/16 (running export LIBRARY_PATH=/opt/X11/lib)
Also adding export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig:/opt/X11/lib/pkgconfig" to my .zshrc file (this is mentioned in the same thread as 1.
When I run pkg-config --list-all | grep x11 the x11 libraries pop up, but for some reason spam can't seem to find it when trying to install graphics. Any suggestions would be helpful!
Here is my current computer configuration:
macOS BigSur Version 11.2.1
Ocaml Compiler 4.11.1
Update:
This issue has been brought up in the following thread (https://github.com/ocaml/graphics/pull/36#issuecomment-846827032), and will be updated in the new graphics release.
The easiest path to get the graphics package working on macOS is to install and properly setup homebrew, after that you can just do
opam depext --install graphics
and it should install the system dependencies via homebrew (xquartz and xorgproto) and install the OCaml library.
I have an error installing utop in fedora 25 when I run "opam install utop". The first time I ran the command some packages were installed, but not all. I ran the same command again and got the error message below. Any suggestion?

I'm having problems very similar to this question.

I've tried reinstalling XCode, I've tried reinstalling ocaml and opam via homebrew with the --build-from-source option, (including rm -rf ~/.opam) and the errors persist.
Has anyone else had issues like this?

=> This package relies on external (system) dependencies that may be missing. `opam depext camlzip.1.05' may help you find the correct installation for your system.
Now I think it's clear the it isn't acctually missing dependencies, but I can the suggested command anyway and it said I wasn't missing any dependencies.
Presumably the problem is with the zlibstubs.c file, but I'm not exactly sure what's happening.
Can anyone hep me out?
TL;DR
opam install depext
opam depext camlzip
Explanations
The opam install depext command will install an opam plugin that is capable of installing external dependencies. It will add a depext command to opam tool.
The opam depext camlzip will install external dependencies, using system package manager. If your package manager is not supported, then the command will fail. In that case you can use
opam list --external --required-by=camlzip
to get all external dependencies of camlzip for all distributions and package management systems known to a package maintainer. From this information you can infer the names of packages for your distribution. Once you succeed, it is also a good idea to contribute this information back to the maintainer.
