/Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr/bin/cc: No such file or directory

Here I had an issue while trying to create the mod_rewrite.so (DSO).

After updating to MacOS X 10.8.x apxs is no longer using the correct path to the cc compiler

So a

$ sudo apxs -c -i mod_rewrite.c

give you

env: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr/bin/cc: No such file or directory

You do have a cc it's just in another place so simply symlink to it

sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.8.xctoolchain/usr/bin/cc

Then run apxs again.

How to do continuous deployment

Continuous Deployment (CD) allows companies like Etsy.com to do up to 30 or 40 deployments a day. Here's a slideshare of how they do it and I've picked some interesting slides.

Cannot find autoconf. Please check your autoconf

I just upgraded to Mountain Lion 10.8.1 and found that doing a pecl install apc failed.

The fix for me was:

Step 1: Download, install and make autoconf

curl -OL http://ftpmirror.gnu.org/autoconf/autoconf-2.68.tar.gz .

tar -xzf autoconf-2.68.tar.gz

cd autoconf-2.68

./configure --prefix=/usr/local

make

sudo make install --prefix=/usr/local

Step 2: pecl install your apc

sudo pecl install apc

Afterwards you should be able to find the .so file here:

/usr/local/lib/php/extensions/no-debug-non-zts-20090626/apc.so


Step 3: Add the extension to your php.ini file

extension=apc.so


Step 4: Restart Apache

Retina effect with jQuery

This is seriously one of the coolest jQuery effects I've seen recently.

/tmp/mysql.sock not found on Mac OS 10.8.1

1. Step 1 Kill all the mysql processes you have
   ps aux | grep mysql sudo kill -9 PROCESS_ID
2. Step 2 Find your mysql.sock file
   locate mysql.sock
3. Step 3 User this file to symlink to /tmp/mysql.sock
   ln -s /private/var/mysql/mysql.sock /tmp/mysql.sock

Adding Google Analytics to your Blogger.com page

1. 
   Step 1:Create your new analytics account if you haven't already.
   
2. 
   Step 2:Go to the account and click the admin button
   
3. Step 3:Choose the Tracking Code tab
4. Step 4:Copy and paste the tracking code you'll find near the bottom
   

   <script type="text/javascript">
     var _gaq = _gaq || [];
     _gaq.push(['_setAccount', 'UA-34933034-1']);
     _gaq.push(['_trackPageview']);
     (function() {
       var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
       ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
       var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
     })();
   </script>

5. 
   Step 5:Open your account in Blogger.com and go to the blog account
6. 
   Step 6:Click Edit HTML and proceed. Then paste in the script code from above underneath right about the tag.
7. Step 7:In your developer tools you can check that this works by looking in your Network secton to see if the __utm.gif is set with the correct account number. To do so click the gif and look for the utmac value (UA-XXXXXX-1) and it should match that value found in the JS you just pasted in.

Adding the GCC compiler for Mac OS 10.8.1 and Xcode

I just installed Mountain Lion on my machine and suddenly my apache would not start due to an error with the mod_rewrite.so file.

sudo /usr/local/apache2/bin/httpd --restart httpd: Syntax error on line 56 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/libexec/apache2/mod_rewrite.so into server: dlopen(/usr/libexec/apache2/mod_rewrite.so, 10): no suitable image found. Did find:\n\t/usr/libexec/apache2/mod_rewrite.so: mach-o, but wrong architecture

Doing a file on mod_rewrite.so gives the following:

file /usr/libexec/apache2/mod_rewrite.so /usr/libexec/apache2/mod_rewrite.so: Mach-O 64-bit bundle x86_64

This tells me that the .so file I have has a 64 bit architecture but my apache is 32 bit.

file /usr/local/apache2/bin/httpd /usr/local/apache2/bin/httpd: Mach-O executable i386

Great, so now I need to find a way (quick and easy without having to change too many things) to compile mod_rewrite for a 32 bit architecture. After alot of Googling I finally decided to update my Xcode to 4.4.1 The download was 1.56G.

Now the download is finished and after updating my locate I did a

locate gcc | grep bin

With this I found the gcc from Xcode that I just installed.

Doing a file gave me

file /Developer/usr/bin/gcc
/Developer/usr/bin/gcc: Mach-O universal binary with 3 architectures
/Developer/usr/bin/gcc (for architecture i386): Mach-O executable i386
/Developer/usr/bin/gcc (for architecture ppc7400): Mach-O executable ppc

So what's the flag for using gcc for the 32 bit architecture?? (IN PROGRESS)
