That was the solution right there. Thank you! The game compiles and runs successfully.

"yum install libnspr4-devel yielded the same results: nothing found. "yum install nspr" says that nspr-4.10.8-1.fc21.x86_64 is already installed and is the latest version. I tried compiling again, but it gives me the same error. So how exactly do I install libnspr4? https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSPR gives instructions for Windows, Mac, Ubuntu, Debian, and openSUSE, but not for Fedora. http://rpmfind.net/linux/rpm2html/search.php?query=libnspr4.so has a Netscape Portable Runtime package for Fedora 21 which I attempted to download and install but without success. I assume it's the development package version that I need, however. These two places are the closest I've come to finding a solution. I can't find any other meaningful information about NSPR. So how do I install this dependency?

Why is this dependency not included in the command to install the other dependencies? su -c 'yum -y install gcc-c++ python subversion zip cmake boost-devel \ libcurl-devel enet-devel libjpeg-devel libpng-devel libvorbis-devel \ libxml2-devel openal-soft-devel pkgconfig SDL2-devel wxGTK-devel \ gloox-devel libicu-devel miniupnpc-devel'libnspr4-dev is not listed in this command, yet is a required dependency. I tried running "yum install libnspr4-dev" and it said the package is not found. I found a suitable RPM package for my OS (Ozon OS based on Fedora 21) and attempted to install it, but it did not work. Also, I don't know where to find the PKG_CONFIG_PATH.

After successfully installing the required dependencies, I received this error after running the following command when attempting to compile the source code per the instructions at http://trac.wildfiregames.com/wiki/BuildInstructions. $ ./update-workspaces.sh -j3Updating bundled third-party dependencies...Building SpiderMonkey...Package nspr was not found in the pkg-config search path.Perhaps you should add the directory containing `nspr.pc'to the PKG_CONFIG_PATH environment variableNo package 'nspr' foundERROR: SpiderMonkey build failed
