CentOS Linux: Can’t install RMagick 2.7.0. Can’t find Magick-config

While prepping a development server earlier this afternoon I ran into an issue installing the rmagick gem. This was one of a list of 30 or so gems required by a Ruby project that was being installed onto the development server. I thought initially something else was wrong because I had run into this issue before but I thought I had installed ImageMagick via the yum package manager to resolve the problem. Anyhow after verifying ImageMagick was installed I still had the same issue on the development CentOS Linux server. Below I describe the error in detail along with what was done to resolve the issue.

Yum Warning: There Are Unfinished Transactions Remaining, You Might Consider Running Yum-Complete-Transaction First To Finish Them

During the build of a Linux development server earlier I performed a “yum update” to update all of the packages after installing CentOS 5.4. I got busy with other tasks and left the server at work without checking to verify that the update had worked properly. Now after dinner I started to get back to work on the server by installing some new packages via yum and received a yum warning message which I describe in greater detail below along with how to resolve the warning.

Error Establishing Connection, Error Playing iPhone iPod Music Over Bluetooth On Windows 7 Computer

We wrote an article awhile back on how to synchronize your iPhone with a 64 bit Windows 7 computer and there have been various comments that we wanted to address in a couple different articles. One of those comments was related to an error attempting to play iPhone iPod application music over bluetooth on your Windows 7 computer. After getting some time we were able to duplicate the exact error which is described in detail below along with a couple tricks that can be used to resolve the issue.

WebEx: Windows Media Player 9.0 Or Higher Is Required To Convert The File To .WMV Format

Earlier I received a webcast that a colleague of mine wanted me to review to see if a certain service would be a fit for our network. The file he sent over had a .WRF file ending which after some research I found out was a WebEx file meaning WebEx Recording Format. To play this type of file you need the WebEx .WRF Player which can be downloaded here or the files can be converted to WMV (Windows Media Format) to play in the Windows Media Player. To convert the file you have to use the WebEx Editor which allows you to open a .WRF file and export to WMV format. When I attempted to export to WMV I received an error which I describe below along with how I was able to resolve the error.

GNU m4 Error: /usr/bin/m4: unrecognized option –debugfile

The m4 error noted in the title and again below is another error I received quite awhile back with very little detail in the notes. I had mentioned that I resolved the error by uninstalling the x86_64 version of m4 and installing the i386 version. After further investigation I am sure the issue was not related to being 32-bit versus 64-bit but instead related to the m4 version instead. Below I describe note the error and how to resolve the error.
