POHow to install the Raspberry Pi cross compiler on my Linux host machine?

Body
copied!<p>I am attempting to get cross-compiling for Raspberry Pi working on my Ubuntu machine. </p> <p>During my initial attempts I was using the arm-linux-gnueabi compiler, which is available in the Ubuntu repo. I got this working. I was able to build all my dependencies and use the cross-compiler in my cmake project.</p> <p>However, I believe I should be using the hf version, so I switched to arm-linux-gnueabihf. Then I realized that this does not work with Raspberry Pi since it is armv6.</p> <p>After some Googling, I then found the <a href="https://github.com/raspberrypi/tools" rel="nofollow noreferrer">pre-built toolchain from GitHub</a>.</p> <p>I downloaded the toolchain, but I don't really understand how to "install" it. I extracted the files to my home directory. The directory structure looks like this:</p> <pre><code>/gcc-linearo-arm-linux-gnueabihf-raspbian /arm-linux-gnueabihf /bin (contains g++, gcc, etc) /lib (contains libstdc++ library) /bin (contains arm-linux-gnueabihf-g++, arm-linux-gnueabihf-...) /lib (gcc lib stuff) </code></pre> <p>If I change directory to the INNER bin folder I am able to compile a test program from the terminal without any problems.</p> <pre><code>~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/ arm-linux-gnueabihf/bin$ g++ test.cpp -o test </code></pre> <p>I then tried to compile a test program in the OUTER bin folder, which contains the prefixed versions of the tools.</p> <pre><code> ~/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin$ arm-linux-gnueabihf-g++ test.cpp -o test </code></pre> <p>However, when I try to use the compiler now (from outside the inner bin directory), it is unable to find the libstdc++ shared library that comes with the toolchain:</p> <pre><code>arm-linux-gnueabihf-gcc: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory. </code></pre> <p>Furthermore, I want to be able to use the compiler without having to navigate to the bin directory. So I tried adding the OUTER bin directory (since I want the prefixed versions) and both lib directories to my PATH:</p> <pre><code>export PATH=$PATH:~/tools/.../bin export PATH=$PATH:~/tools/.../lib export PATH=$PATH:~/tools/.../.../lib </code></pre> <p>However, this results in the same error. How should I "install" the toolchain so that I can use the toolchain from everywhere, just like I can when I use the cross-compilers from the Ubuntu repo?</p>
