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.

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 just updated to OS X Mavericks and it seems it messed up my whole compiler setup. Not only do I have to reinstall a JDK in order to use a Java compiler, I get the following error when I'm trying to compile C/C++ using GCC/G++:
/usr/local/Cellar/gcc/4.7.2/gcc/lib/gcc/x86_64-apple-darwin12.2.1/4.7.2/../../../../include/c++/4.7.2/cwchar:46:19: fatal error: wchar.h: No such file or directory
Not sure what to think other than upgrading messed it up. My question is: how do I set up g++ to compile on OS X? If it's already set up, what is the problem here?
If I can provide more information, please let me know.
Note: I've installed gcc 4.7 using homebrew, but it doesn't seem to work. When I use g++-4.7 code.cpp specifically, I get the same error.
Installing the Command Line Tools (OS X Mavericks) for Xcode - Late October 2013 solved it for me. Here is the link:
OSX: Xcode Downloads
The often mentioned xcode-select --install command kept saying it cannot find the requested software.
To clarify: You need to already have gcc-4.7 installed using Homebrew. The update to the latest version of CMD Tools only fixes compatibility issues caused by upgrading from Mountain Lion to Mavericks.
I am not a pro-user of Mac, so I am having a lot of problems to install software. I would like to run the Z3Py (Z3 API using Python). I download Z3 v4.3.1, I installed clang v2.9 using Macports-2.1.2 and finally, when I run for Z3
>autoconf
>./configure CXX=clang++
>python scripts/mk_make.py
>cd build
>make
I obtained:
src/shell/datalog_frontend.cpp
make: clang++: Command not found
make: *** [shell/datalog_frontend.o] Error 127
Since clang++ is in /opt/local/libexec/llvm-2.9/bin
I am not able to understand what it is happening and how to solve it. I really appreciate whatever hint because after two days trying I have not find any solution.
I just tried to replicate this error report, but I was unable to do so. Z3 builds just fine with CXX=clang++ on my machine. I can only suspect that your clang++, while it may be installed, is not in the path. For instance, simply running clang++ in the console would throw the same "command not found" error. Perhaps this could be fixed by simply running
export PATH=$PATH:/opt/local/libexec/llvm-2.9/bin
before attempting compilation. However, I suspect there would be more issues with libraries not being found after that.
I could imagine that something went wrong during the installation via MacPorts, e.g., that it requires modifications to various environment variables which are not done automatically.
As Nuno suggests, XCode (with CLI tools) may be much easier to use and they should be available for free in the AppStore.
You should install XCode CLI tools instead. It already includes an up-to-date version of clang (2.9 is very old).
I think both XCode and XCode CLI tools are free on Appstore and/or apple developer center.
After upgrading to Mountain Lion (10.8) and XCode 4.4, and installing the XCode Command Line utilities from the XCode Preferences pane, I was unable to compile node.js (0.8.5) from source. Specifically, the configure script believed that I did not have a C compiler installed.
It looks to me like the environment variables required for the command line tools were lost somewhere along the way.
I tried sudo xcode-select --switch /Applications/Xcode.app but this did not appear to clear up the problem.
I had to perform these steps to make the node build system happy:
export PATH=$PATH:/Applications/Xcode.app/Contents/Developer/usr/bin
export CC='gcc --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/'
export CXX='g++ --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/'
After that I was able to compile and link.
So... why did I have to do this? Am I missing some easy step that could have done this for me automatically? Or am I in some bad state because I installed XCode before upgrading to Mountain Lion, and the XCode updater went off the rails?
Once you've updated to Mountain Lion and updated XCode 4.4, you have to reinstall the command line tools inside XCode.
Go to XCode/Preferences/Downloads/Components and click install on "Command Line Tools" and once it has downloaded and installed, you should once again have gcc and g++ in your (normal) path.
The correct thing to do was to reinstall the command-line tools from inside Xcode.
This was temporarily impossible because a malformed download list was being served by Apple, but the problem was fixed. The malformation was detectable by inspecting the output from Xcode in Console.
Once the tools were reinstalled, compilation worked normally.

Please refer the above link and try to install command line from apple developer portals
I'm trying to make a Xcode project from the Insight Toolkit (ITK, itk.org). I issued the following command into the terminal:
ccmake -DCMAKE_C_COMPILER=/Applications/Xcode.app/Contents/Developer/usr/bin/gcc -DCMAKE_CXX_COMPILER=/Applications/Xcode.app/Contents/Developer/usr/bin/g++ -GXcode /<path to source>
When I try to generate the project it fails with this error:
CMake Error at /Applications/CMake 2.8-7.app/Contents/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:52 (MESSAGE):
The C compiler "/Applications/Xcode.app/Contents/Developer/usr/bin/gcc" is not able to compile a simple test program.
It fails with the following output:
Change Dir: /<path to destination folder>/CMakeFiles/CMakeTmp
Run Build Command:/Applications/CMake\ 2.8-7.app/Contents/bin/cmakexbuild -project CMAKE_TRY_COMPILE.xcode build -target cmTryCompileExec -buildstyle Development
xcodebuild: error: option '-buildstyle' is no longer supported
How can I configure the call to cmakexbuild? I haven't found a respective entry in the CMake configuration menu.
I have found similar problems from other users with other projects so I assume it's a problem with the CMake configuration.
I'm using Xcode 4.3 and CMake 2.8.7 on Mac OS X Lion 10.7.3.
Thanks for your help,
Paul
It's a CMake bug and it seem to be been fixed in development version:
http://public.kitware.com/Bug/view.php?id=12621
You can fix this by telling OSX which version of Xcode you want to use. If you installed 4.3, it has moved to the Apps folder, along with all the tools. Previously they were all in /Developer. Do the following and try again.
sudo /usr/bin/xcode-select -switch /Applications/Xcode.app/Contents/Developer
You may also have to install the command-line tools. I already installed these so I don't know what will happen without them.
cmake 2.8.8 rc1 is out now. Perhaps try that. I think it has solved my problem. :)
