I am trying to get Ogre on Linux. I downloaded the source files and uncompressed them. Then I created the build folder then I ran "cmake ..". After that completed, I ran "make -j4" (I do have 4 cores and I have also tried just make). I get to 49% and it stops every time. I have downloaded the cmake gui and ran configure and checked all the boxes. I hit configure again and then generate. I tried running "make" again.
Downloads/ogre_src_v1-8-1/RenderSystems/GL/src/atifs/src/ps_1_4.cpp:689:1: error: narrowing conversion of ‘-35051’ from ‘int’ to ‘uint {aka unsigned int}’ inside { } [-Wnarrowing] };
That is the error that pops up several times except they refer to a different line of the code in ps_1_4.cpp and the number ‘-35051’ is different.
Also, There are several warnings for casting the const GLboolean* to GLboolean* throughout the build but this is the message that I have at the end:
RenderSystems/GL/CMakeFiles/RenderSystem_GL.dir/build.make:542: recipe for target 'RenderSystems/GL/CMakeFiles/RenderSystem_GL.dir/__/__/RenderSystem_GL/compile_RenderSystem_GL_0.cpp.o' failed
make[2]: *** [RenderSystems/GL/CMakeFiles/RenderSystem_GL.dir/__/__/RenderSystem_GL/compile_RenderSystem_GL_0.cpp.o] Error 1
CMakeFiles/Makefile2:1057: recipe for target 'RenderSystems/GL/CMakeFiles/RenderSystem_GL.dir/all' failed
make[1]: *** [RenderSystems/GL/CMakeFiles/RenderSystem_GL.dir/all] Error 2
Makefile:160: recipe for target 'all' failed
make: *** [all] Error 2
Also every time that I have tried a new way I delete the build folder and start all over. Each time it appears to end with this message. I am still relatively new to Linux and CMake, so can you explain what is going on and how you came to this conclusion?
Note: I have found one forum that talks about this but I don't know where the build function is or how to change the CXX_FLAG.
Referenced post suggests that Ogre can be successfully built using gnu++98 standard (which is actually a c++98 plus GNU extensions).
The standard is set via compiler flags, in case of cmake flags may be passed as:
cmake -DCMAKE_CXX_FLAGS="--std=gnu++98" ..
