I recently upgraded xcode command line tools to version 2384. After this I decided to reinstall gcc which was installed with homebrew. Installation completed with no errors but when I tried to compile a simple code with iostream library, it gave an error saying:
/usr/local/Cellar/gcc/10.2.0/include/c++/10.2.0/cwchar:44:10: fatal error: wchar.h: No such file or directory
Later, I checked the library folder and there were multiple files missing such as assert.h. I want to ask is there any way to fix this other than installing every file one by one? I already tried updating homebrew and xcode command line tools.

I have been stuck on this for a while, and I was wondering if I could get some help.
I'm currently stuck trying to run a cmake setup file and I'm constantly getting this error
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/stdio.h:107:15: fatal error: 'stdio.h' file not found
I've been looking online, and haven't been able to find anything recent. I've tried using the xcode-select --install already.
cmake version is currently 3.21.3.
The library I'm trying to install is https://github.com/google/draco, where I'm trying to install python functions using pybind11. I was able to install this library through cmake, whoever when I try to install the pybind11 functionality I keep getting this error. This library seemed to function properly on a coworkers linux machine, and they were running cmake 3.20.4 on ubuntu 18.04 (I don't know if this makes a difference)
Any help would be appreciated, and please let me know if there's any other information that can help the process.
It looks like something in XCode has changed after updating MacOS to 12.3. I had to reinstall XCode command line tools. I don't say it's right solution, but it works for me.
Commands for reinstalling (from https://stackoverflow.com/a/47804075):
removing the old tools ($ sudo rm -rf /Library/Developer/CommandLineTools)
install xcode command line tools again ($ xcode-select --install).
I recently installed Octave using the binary installer found on this site: http://wiki.octave.org/Octave_for_MacOS_X
I then tried to install the control package using 'pkg install -forge control' but it gave me the error 'pkg: error running `make' for the control package.'. I have gone through most of the threads regarding this error but with no success.
I then tried to use MacPorts to install the control package, I followed the instructions on the wiki page above with some help from this thread: Installing general package in octave has error. I believe I succeeded installing the packages because I can see them in the folder tree for Octave and MacPorts says it is installed when using the console.
The problem is that when i run some code in Octave it cannot build as it doesn't know that I have installed any additional packages. Using 'pkg list' in Octave it says that no additional packages installed. I feel like I need to link the two together but I don't know how?
I'll happily explain more if I need to and I hope you can help me out.
Many Thanks,
Sam.
You cannot "link the two together" (assuming you mean the binary version of octave and the MacPorts version).
If you have packages installed via MacPorts for the MacPorts version of octave, then they will only be available from the the MacPorts version of octave, so make sure you are running that.
Otherwise, figure out how to install the package with the octave binary version. It seems you require a build environment for this, but installing the command line tools (which you must have done for MacPorts to work) might have already solved this problem.
It seems to be a problem with gfortan compiler built-in with Octave. To solve this you should install an external fortran compiler.
Try this:
Install Xcode and command line tools for Xcode
Download and install a fortran compiler for MacOS, for example: http://coudert.name/software/gfortran-6.1-ElCapitan.dmg
Change the fortran compiler path in your octave, to this if you installed the compiler that I suggested in point number 2 you only must to open Octave and type: setenv('F77', '/usr/local/gfortran/bin/gfortran').
And Enjoy Octave for MacOS
Octave with control package 3.0.0 on MacOS
You haven't provided enough information for a precise diagnostic, but I had the same error message (and a few more), and re-installing octave from source solved it; see this link for more info, but essentially you can do it by running brew reinstall --build-from-source octave.
I had installed command line tools when I installed Xcode 5 in my mac.
install_name_tool was working fine back then.
Now, When I try to use install_name_tool I get following error, malformed object (unknown load command 4)
Upon googling I found out that this error is due to the command line tools are not updated along with OS or Xcode. So i went here (https://developer.apple.com/downloads/index.action) downloaded the command line tools for 10.9, and tried again on terminal, but the error persisted.
Then I tried updating my Xcode from 5-->5.1.1, went to Downloads in preferences, there was no option to download the command line tools. I installed the pkg which I downloaded earlier for command line tools, I am still getting the same error.
install_name_tools doesnt exist in this director, as one of the answers on other similar questions suggested--- > /Applications/Xcode.app/Contents/Developer/usr/bin/
My question, where does the install_name_tool gets installed after installing it from a pkg?
I was actually trying to update ruby on my OSX 10.7.5 with RVM, and after typing in the following command:
rvm install ruby
I got the following response:
Searching for binary rubies, this might take some time.
Checking requirements for osx.
Installing requirements for osx.
Updating system.......
Error running 'requirements_osx_brew_update_system ruby-2.0.0-p247',
please read /Users/username/.rvm/log/1381215459_ruby-2.0.0-p247/update_system.log
Requirements installation failed with status: 1.
Then, when I checked out the update_system.log, it showed me the actual code of a function called requirements_osx_brew_update_system(), which contained the following error message:
Xcode version older than 4.6.2 installed, download and install newer version from:
http://connect.apple.com
After installation open Xcode, go to Downloads and install Command Line Tools.
Then I proceeded to find an update for Xcode, but only found the latest Xcode 5.0, which is apparently incompatible with my OSX 10.7. Although ultimately my goal is to update ruby and install rails, which I'm sure there are many other ways to do, I'd still like to find out if I could possibly install Xcode 4.6.2 on my OSX 10.7.
UPDATE: Sorry folks, apparently my version of XCode is v4.6.1 so updating the command line tools will not work in all cases (I know for a fact it doesn't work if you're on XCode v4.3.3). YMMV
I ran into the same issue trying to do an rvm install. I got an error telling me that I needed XCode 4.6.2 or later.
Turns out all it needed was the latest version of the XCode command line tools. I followed the instructions for upgrading my command line tools from this macports article:
open the Xcode application
go to the Preferences window
open the Downloads section
click the Install button next to "Command Line Tools"
After doing this I was able to run my rvm install command and it didn't complain about upgrading XCode anymore (and finished successfully).
It seems you're going to have to install under Xcode 5. So go to https://developer.apple.com/downloads/ and log in with your developer ID to get to the older versions. There should be a 4.6.3 that you could potentially download, or even 4.6.2.
Or you could upgrade your OSX to 10.8.
Whichever you prefer.
I can't give you a direct link to it, since you need your developer information to log in yourself. But all the downloads you need are in the link provided above once you log in.
Open xcode and update it via the app store.
Then
xcode-select --install
This will install xcode via the command line
I'm getting this error when I try and install node on my new mac
error: could not configure a cxx compiler!
The error always occurs when I get to the ./configure part of the installation
I found this problem which applies to a linux build with the same error, but the solution does not seem to apply in my case:
How to compile/install node.js(could not configure a cxx compiler!) (Ubuntu).
I also took a look at the troubleshoot guide on the node wiki here:
https://github.com/joyent/node/wiki/Troubleshooting-Installation
and tried this solution:
export PATH=/Developer/usr/bin:$PATH
ISYSROOT="-isysroot /Developer/SDKs/MacOSX10.5.sdk"
export LINKFLAGS=$ISYSROOT CXXFLAGS=$ISYSROOT CFLAGS=$ISYSROOT
./configure --prefix=$HOME --without-ssl
make
But I get the same problem when I get to the ./configure step
Any advice, insights or help would be much appreciated here.
Thanks
When you install Mac OS X Developer Tools (XCode, etc) ensure you have the Unix Tools option checked. I had to remember to install Developer Tools/Unix tools when I set up my new MBP and it resolved this error for me.
Optionally, you could remove and try installing with Homebrew. However, it still has the same requirements (XCode/Dev Tools) so ensure that you have those installed.
Hope this helps.
I had this problem too, I resolved this in a different way, as far as I know xcode 4.3.1 doesnt come with an Install Xcode.app file from the appstore, if you are under this case, just run xcode, go to preferences -> downloads and click on the Install button for the command line tools option. I did just that and all the errors on the .configure and make commands were gone :)
I had the same problem on OSX 10.7 with Xcode 4.2. I was trying to build node v0.4.7. I kept getting "unable to configure a c compiler" error. What finally worked for me is installing the GCC compiler seperately. I found a nice package for that here:
https://github.com/kennethreitz/osx-gcc-installer/
configure is currently broken for some versions of MacOS; for more details, see How to compile Node.js v0.4.2 on MacOS 10.5.8. The working approach cited there is as follows:
export PATH=/Developer/usr/bin:$PATH
ISYSROOT="-isysroot /Developer/SDKs/MacOSX10.5.sdk"
export LINKFLAGS=$ISYSROOT CXXFLAGS=$ISYSROOT CFLAGS=$ISYSROOT
./configure --prefix=$HOME --without-ssl
make
This worked for me .

After installing XCode 4.3.2 (in Mac OS X Lion) I still had the error.
Open XCode, Preferences, Downloads and installed Command Line Tools.
After it gets installed ./configure runs ok.
