ogles_gpgpu compile error
FFFFFUNKYMUZIK opened this issue · 3 comments
Hello, I'm trying to compile this project in my local Ubuntu 14.04, but I suffered from the compile error.
I'm not friendly with hunter as well, I want you to figure out what causes these problems.
On project root directory first I enter the following on the console:
source ./bin/acf/hunter_env.sh
and next:
polly.py --config Debug --install --verbose
for compiling it with default native compiler(gcc, g++ 4.8.4) on my ubuntu.
compile is processing on openCV and other sub projects, but It ended at ogles_gpgpu and FAIL with following grammer error messages:
proc/base/filterprocbase.h:114:47: error: ‘nullptr’ was not declared in this scope
const char* fragShaderSrcForCompilation = nullptr; // used fragment shader source for shader compilation
proc/base/procbase.h:164:65: error: ISO C++ forbids declaration of ‘delegate’ with no type [-fpermissive]
virtual void getResultData(const FrameDelegate& delegate = {}, int index = 0) const;
proc/base/procbase.cpp:111:5: error: ‘fbo’ was not declared in this scope
fbo->readBuffer(data, index);
^
there are plenty of error messages like these. What should I do for these problems?
You need to use a C++11 compiler. I believe 4.8 implements most of C++11, but you need to specify a toolchain in order to enable that with -std=c++11

I think that will work. In general it will be better to use g++-5, which is tested in the CI config. Here are two examples of gcc w/ C++11 toolchains that should work:
Thank you for your support!!!
Actually I compiled with gcc-4-8-c11 compiler right after post this issue, but there's some build issues.
It fails at building libprotobuf, error log is like following:

When I use g++-5 compiler, it success without any compile issue.
Thanks a lot!
👍
The opencv protobuf dependency fails on several not-quite-latest compilers for some reason. It isn't required for acf and another fix would be just to exclude it from the OpenCV dependency list in the LOCAL config, although g++-5 is probably a better/easier fix.
