Hi. I am trying to build a sample program given in Examples folder in the SDK but I can’t find any makefile or configure file. Can anyone tell me how can I build any sample program from its code ? ---

Thanks for the reply. But I have a doubt in the very first step. "Define the TOOLCHAIN environment variable to the toolchain directory, or add the path to the toolchain to the PATH environment variable (i.e. run export PATH=“path to the toolchain:$PATH”)." What is a TOOLCHAIN and where can I find it ? Sorry for the silly doubt but I am new to all this. ---

Its really a matter of taste and opinion about preferences 🙂 ---

I have some more doubts. I 'll list them all : 1. You did a X11 build, then why didn’t you perform the second step i.e. “export X11ROOT=/usr/X11R6\_SGX”. 2. According to your first command, is the location of the toolchain the SDK\_3.1 directory present in the Imagination SDK installation folder i.e. (C:ImaginationPowerVRGraphicsSDKSDK\_3.1) ? 3. According to your machine, the first line printed after doing make has -march=i686 -I **toolchain-directory** /Builds/Include… But I set my toolchain directory as **/usr/ig86-pc-cygwin/bin** and after doing make, my first line which is printed contains : -march=i686 -I/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Builds/Include… g++ -DBUILD\_OGLES2 -DRELEASE -O2 -m32 -march=i686 -I/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Builds/Include -I/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Shell -I/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Shell/API/KEGL -I/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Shell/OS/LinuxX11 -I/usr/X11R6\_SGX/include -MF"…/Linux\_x86\_32/ReleaseX11/OGLES2IntroducingPVRShell.d" -MG -MM -MP -MT"…/Linux\_x86\_32/ReleaseX11/OGLES2IntroducingPVRShell.d" -MT"…/Linux\_x86\_32/ReleaseX11/OGLES2IntroducingPVRShell.o" "…/…/OGLES2IntroducingPVRShell.cpp" g++ -c -DBUILD\_OGLES2 -DRELEASE -O2 -m32 -march=i686 -I/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Builds/Include -I/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Shell -I/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Shell/API/KEGL -I/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Shell/OS/LinuxX11 -I/usr/X11R6\_SGX/include …/…/OGLES2IntroducingPVRShell.cpp -o…/Linux\_x86\_32/ReleaseX11/OGLES2IntroducingPVRShell.o 4.

hi, i use of course Linux Ubuntu 🙂 if your are using window why not use visual studio ? about your question 1/ it s already in my path and my gnu toolchain as well. are you able to compile ? about step 4 set YOUR LIBRARYPATH in my case :/home/dgu/2015sdk/SDK\_3.1/Builds/Linux/x86\_32/Lib export LD\_LIBRARY\_PATH=YOUR LIBRARYPATH into /etc/bash.profile kind regards david ---

Yes, I am able to compile and generate the following files : OGLES2IntroducingPVRShell.d OGLES2IntroducingPVRShell.o PVRShell.d PVRShell.o PVRShellAPI.d PVRShellAPI.o PVRShellOS.d PVRShellOS.o But the final linking step to create an executable fails. I exported LD\_LIBRARY\_PATH to /etc/profile but still it cannot find **libGLESv2.so** Is it due to because I did **export X11ROOT=/usr/X11R6\_SGX** and after **make PLATFORM=Linux\_x86\_32 X11BUILD=1** , it searches for “GLESv2” in **/usr/X11R6\_SGX/lib** and when I do “ls” in /usr, I don’t see any “X11R6\_SGX” directory. g++ -o …/Linux\_x86\_32/ReleaseX11/OGLES2IntroducingPVRShell …/Linux\_x86\_32/ReleaseX11/OGLES2IntroducingPVRShell.o …/Linux\_x86\_32/ReleaseX11/PVRShell.o …/Linux\_x86\_32/ReleaseX11/PVRShellAPI.o …/Linux\_x86\_32/ReleaseX11/PVRShellOS.o -m32 -L **/usr/X11R6\_SGX/lib -lX11 -lXau -lGLESv2 -lEGL** -L"/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Builds/Linux/x86\_32/Lib" -Wl,–rpath-link,"/cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1/Builds/Linux/x86\_32/Lib" …/…/…/…/…/…/Builds/Linux/make\_example.mak:46: recipe for target `…/Linux\_x86\_32/ReleaseX11/OGLES2IntroducingPVRShell’ failed Do I also need to include /cygdrive/c/Imagination/PowerVR/GraphicsSDK/SDK\_3.1ToolsOGLES2/Build/Linux\_x86\_32/ReleaseX11/libogles2tools.a to any library path ?

Hello i see, yes include this lib as well the mandatory lib under linux X11 ARE : GLESv2;EGL;X11 the /usr/X11R6\_SGX given in the doc are just a sample. i do not have this directoy, maybe this should be removed because it s not clear. ---

if the library is in the ld path then this error should not happend , it s seems that the ld path is wrong . You mention that -L/usr/X11R6\_SGX/lib doesnt exist in your machine , then you should remove it. the directory you mention is then wrong . some helper [http://www.gnu.org/software/libtool/](http://www.gnu.org/software/libtool/) ---
