I've checked a number of similar questions on stackoverflow but haven't found an answer yet.
I'm trying to install memcached on Lion OSX as shown here.
Here's what I'm getting:
j-court-demones-macbook-pro:libevent-1.4.12-stable jcourtdemone$ ./configure; make

I've reinstalled Xcode as was recommended in a couple places, but no dice.
Here's my config.log:

configure: exit 77
I have 10.8 installed and Xcode 4.4 with Command Line tools, and yet I was still getting this error. Rather than reinstall Xcode, I noticed there were two relevant lines in my config.log:
configure:5130: checking for C compiler version
configure:5139: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr/bin/cc --version >&5
That path did not exist for me. Instead I had:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain
The C compiler ("cc") is located inside of that xctoolchain directory. I created a symlink for OSX10.8.xctoolchain to point to XcodeDefault.xctoolchain and that fixed it. Now the memcached installation script can find the compiler version and continue on its way.
cd /Applications/Xcode.app/Contents/Developer/Toolchains
sudo ln -s XcodeDefault.xctoolchain OSX10.8.xctoolchain
As suggested in the comments, if you are having this problem on Yosemite (10.10) or Mavericks (10.9), you can update the symlink command above to point to that specific version (OSX10.9.xctoolchain or OSX10.10.xctoolchain).
First get the gcc path using
Command: which gcc
Output: /usr/bin/gcc
I had the same issue, Please set the gcc path in below command and install
CC=/usr/bin/gcc rvm install 1.9.3
Later if you get "Ruby was built without documentation" run below command
rvm docs generate-ri
Ensures the path to Xcode.app bundle is without space or strange characters. I have Xcode installed in ~/Downloads/Last Dev Tools/ folder, so with spaces and renaming the folder to LastDevTools fixed this (after resetting xcode-select -p though)
Check where your clang is located:
which clang
It should be somewhere under /usr/bin/clang.
In my case from old times it was coming from Miniconda that was put artificially on the command line PATH. Fix that so that clang comes from Xcode and that should bring you forward.
For me it was a problem with gcc, highlighted by gcc -v. It was down to upgrading Xcode recently this post said to do sudo xcode-select -switch /Applications/Xcode.app which fixed the issue.
If anyone is coming here because RVM / Ruby is creating issues (Middleman/Grunt) I've solved my issue.
PS. The answer by steroscott fixed my issue a while back...this time around not the case.
In my case rvm is trying to use a downloaded gcc via homebrew. I ran a brew uninstall of gcc (gcc46 for me) and reran the code for the ruby installation (old project old ruby v)
$ brew uninstall gcc46
$ rvm install 1.9.3
during that process of checking for requirements it automatically fetched a newer gcc for me and boom, all is working now. Oh a big note, the gcc install from the rvm command can take around 10-15 minutes without throwing out any text, it's not frozen :) Good luck
I just had this issue building apache. The solution I used was the same as Mostafa, I had to export 2 variables:
export CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc
CPP='/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc -E'
This was one Mac OSX Mavericks
I furiously read all of this page, hoping to find a solution for:
"configure: error: C compiler cannot create executables"
In the end nothing worked, because my problem was a "typing" one, and was related to CFLAGS. In my .bash_profile file I had:
export ARM_ARCH="arm64”
export CFLAGS="-arch ${ARM_ARCH}"
As you can observe --- export ARM_ARCH="arm64” --- the last quote sign is not the same with the first quote sign. The first one ( " ) is legal while the second one ( ” ) is not.
This happended because I made the mistake to use TextEdit (I'm working under MacOS), and this is apparently a feature called SmartQuotes: the quote sign CHANGES BY ITSELF TO THE ILLEGAL STYLE whenever you edit something just next to it.
Lesson learned: use a proper text editor...
I had already installed the command line tools in xcode but I mine still errored out on:
line 3619: /usr/bin/gcc-4.2: No such file or directory
When I entered which gcc it returned
/usr/bin/gcc
When I entered gcc -v I got a bunch of stuff then
..
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)
So I created a symlink:
cd /usr/bin
sudo ln -s gcc gcc-4.2
And it worked!
(the config.log file is located in the directory that make is trying to build something in)
When you see this error message, you might not have accepted the Xcode license agreement yet after an upgrade.
First of all, make sure you have upgraded your commandline tools:
$ xcode-select --install
Now Apple wants you to agree to their license before you can use these tools:
$ gcc
Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.
$ sudo gcc
You have not agreed to the Xcode license agreements. You must agree to both license agreements below in order to use Xcode.
[...]
After you have accepted it, the commandline tools will work as expected.
About clang iOS cross-compiler
I've found that the problem was at miphoneos-version-min=5.0 . I've changed into miphoneos-version-min=8.0 . Now it works.
I just want suggest to use create a simple test.c file and compile it by the command write in the log.
Make sure there are no spaces in your Xcode application name (can happen if you keep older versions around - for example renaming it 'Xcode 4.app'); build tools will be referenced within the Xcode bundle paths, and many scripts can't handle references with spaces properly.
I just had this issue building react-native app when I try to install Pod. I had to export 2 variables:
export CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc
CPP='/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc -E'
In my case, I tried xcode-select --install but it says that it's not available from the store. Then, inspired by Rimian, I checked my gcc : gcc -v and then I got a message saying I did not aggreed.
From that point I just followed the agreement process from gcc -v, after I agreed it works fine for me.
Setting 'clang' as the compiler configure should use worked for me:
export CC=clang
pip install --no-clean pycrypto
