I need to use the old version for cmake but I can't find the formula in homebrew, is that a way to install cmake 3.12 using Homebrew?
EDITED: the solution presented here is much more objective considering the answers from the previous question.
Brief
# install cmake 3.12.4
brew install https://github.com/Homebrew/homebrew-core/raw/a3b64391ebace30b84de8e7997665a1621c0b2c0/Formula/cmake.rb
Detail
You could install it from specific formula file.
Go to homebrew/homebrew-core, the place where package formula is stored.
Use the search bar to search "cmake" in this repository.
Find the specific commit you want.
Enter it. And find the RAW url for this cmake.rb file.
Install it with brew install url-to-cmake.rb.

I have installed Qt 5.1.4 but when I 'make install' it shows
Package Qt5Gui was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Gui.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Qt5Gui' found
Package Qt5Widgets was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Widgets.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Qt5Widgets' found
Package Qt5Multimedia was not found in the pkg-config search path.
Perhaps you should add the directory containing `Qt5Multimedia.pc'
to the PKG_CONFIG_PATH environment variable
No package 'Qt5Multimedia' found
But I installed this software qt-opensource-linux-x64-5.14.0.run, after I tried to find them I ran locate Qt5Gui but no Qt5Gui.pc returned,so how can i get Qt5*.pc on my ubuntu 20.04 ?
The installation I started was missing a few more packages
The complete installation should look like this
sudo apt install qtmultimedia5-dev qt5-default -y
The construction of the qt compilation environment requires more than the installation package downloaded from the official website
It worked for me !
Now i can find the Qt5*.pc !
You need to install qtbase5-dev which is part of qt5-default
see: https://packages.ubuntu.com/bionic/amd64/qtbase5-dev/filelist
EDIT: you may also have to install the package qtmultimedia5-dev.
I am using Mac for development. I installed Rust 1.13.0 using brew install rust and the Rust plugin 0.1.0.1385 for IntelliJ IDEA. I created my first test project with cargo and while opening it with IDEA I got the message
No standard library sources found, some code insight will not work
I haven't found any sources installed, nor the Rust sources package in Homebrew.
How do I provide sources for the project and what are the practical implication if I ignore this step?
As commented, the supported approach is to use rustup:
Navigate to https://rustup.rs/ and follow the installation instructions for your platform.
Add the rust-src component by running: rustup component add rust-src
Create a new Rust project in IntelliJ and choose your existing Rust project source. If the folder already contains previous IntelliJ project files, you may have to delete those first before it will let you proceed.
IntelliJ-Rust should automatically configure the standard library sources to point to the sources downloaded by rustup.
As a reference, since the question title is broad, for Fedora 28 I had to:
dnf install cargo rust-src
sudo ln -s /usr/lib/rustlib/src /usr/lib/rustlib/x86_64-unknown-linux-gnu/
then give /usr/lib/rustlib/x86_64-unknown-linux-gnu/src/rust/src as "Standard library"
Full setup:
Issue opened to simplify the process
When not using the rustup installer, one can install the source package and direct the rust plugin to use those:
(Tested with CLion 2020.2.1, rust-1.46.0-x86_64-pc-windows-gnu.msi, rustc-1.46.0-src.tar.gz. Offline Rust installers and source archive from there: https://forge.rust-lang.org/infra/other-installation-methods.html )
Although the preferred way of installing Rust is by using rustup, as pointed out by the other posts, it is not uncommon to use the packages that your distro makes available.
I use, for example, the packages provided by Gentoo and I share the same problem about the not prefilled field for standard libraries.
Nevertheless, you can easily find out where your standard libraries have been installed by typing the following find command:
find /usr/lib* -type d -name "rust" | grep src
or the following if you installed rust in your home
find -type d -name "rust" | grep src
The previous commands will help, unless, of course, in your distro there is a package for the binaries and one for the source and you only installed the binary one.
I know the question is for MacOS but this answer is shown up when searching for it on Linux. Below I will answer for Ubuntu.
The path is /usr/lib/rustlib/src/rust/src for Ubuntu 20.04
The way I did is:
Installed rustc from the repositories, which includes cargo
sudo apt install rustc
Then installed rust source package
sudo apt install rust-src
I used apt-file (can be installed with sudo apt install apt-file) to search for the install path of the sources
sudo apt-file update
apt-file list rust-src
This show the path as /usr/src/rustc-1.41.0/src .
But a ls -la in /usr/lib/rustlib/ will reveal symlinks and /usr/lib/rustlib/src/rust/src points to the previous found directory.
Using the symlink on IntelliJ will survive new rust versions.
For Fedora 32 install Rust using command:
dnf install cargo rust-src
and the path to standard libary source is:
/usr/lib/rustlib/src/rust
I used Ubuntu. I follow these steps:
sudo apt install rust-src
wait for the install, then
dpkg -L rust-src
copy the last line. For me it is the standard library path:
/usr/lib/rustlib/src/rust
For MacOS, you need to put /opt/homebrew/bin/.
I am using Point cloud library 1.5.1. When I run CMake 3.4.0-rc2 to build my project, it has error:
Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE)
How do I fix this error?
This error is raised because the pkg-config utility is not available on your system.
Using PkgConfig with CMake is not a truly cross-platform solution, as Windows does not come with the pkg-config utility installed. (The PCL developers should instead use find_package() in their CMake. Perhaps, this is worth opening up a bug report on their Github.) On Linux, this is an easy fix; you can install pkg-config like this:
sudo apt-get install pkg-config
However, on Windows, the process is more involved. There are several solutions for installing pkg-config on Windows documented here. I'm not sure which most directly applies to your situation, so I suggest reading through some of those. After successfully installing the pkg-config utility on your Windows machine, clear your CMake cache, and re-run CMake. This should remove the error, and allow your build to proceed.
Install vcpkg: https://vcpkg.io/en/getting-started.html
Install pkgconf:
.\vcpkg install pkgconf
If use CMake, delete the Cache files/folders: CMakeCache.txt and CMakeFiles. After that, run the command
cmake .. -DCMAKE_TOOLCHAIN_FILE=C:\dev\vcpkg\scripts\buildsystems\vcpkg.cmake
On Fedora 34, it was because of multiple pkg-config
/home/sapillai/go/bin/pkg-config
/home/sapillai/go/bin/pkg-config
/usr/bin/pkg-config
/home/sapillai/go/bin/pkg-config
I deleted the others and kept /usr/bin/pkg-config. Error was gone.
Suppose I want to install python2.7 with yum, and do
sudo yum install python27
This will install a python2.7 in the /usr/bin directory. However, the symbolic link /usr/bin/python still points to python2.6.
Is there a yum command that can manage this symbolic link rather than doing it manually? I know the port select in MacPorts does so, and am looking for a counterpart in yum. Thanks a lot!
Unless the distribution has been set up to handle this sort of thing (the way debian and some others are) you do not want to be changing the default value of something like /usr/bin/python because you will break anything the distribution packages which depends on the default python being the version of python in the default python package.
Things built against the python27 package almost certainly use /usr/bin/python2.7 when they need to run python scripts and/or on their shebang lines. Things packaged by the default system almost certainly just use /usr/bin/python assuming that is the default system python version.

./configure results in:
configure: error: Package requirements (mono >= 2.4.3) were not met:
No package 'mono' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables MONO_MODULE_CFLAGS
and MONO_MODULE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
which mono
/bin/mono
echo $PKG_CONFIG_PATH
/usr/local/lib/pkgconfig
but if I check for pkgconfig,
which pkgconfig
/usr/bin/which: no pkgconfig in (/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)
yum provides pkgconfig

Repo : base
yum install pkgconfig
Package 1:pkgconfig-0.27.1-4.el7.x86_64 already installed and latest version
A similar question was asked last year with no accepted answer. One of the answers pointed to a now non-existent page with a purported solution.
I believe pkg-config itself is working all right, configure is not complaining about that. What's missing is the entry for mono in the pkg-config database. Make sure you have mono.pc in /usr/local/lib/pkgconfig, or add wherever you have this file to PKG_CONFIG_PATH as instructed. On some linux distributions, development packages need to be separately installed, such as libmono-cil-dev on debian.
