I'm trying to install Open Transactions, the open-source project, on a debian 8. I've installed all the dependencies and am having an issue when compiling (make). The following error is showing at my terminal, even though i made sure to install the protobuf project:

Any ideas on how to deal with this? Couldn't find any help online.
I had the same problem on Ubuntu 14.04 and I fix it as you said . But I am just writing to explain more the issue.
So , After googling the error I found this discussion . In which they describe that the problem arises from the fact that the google coders are relying on the fact that the C++ standard allows you to treat an undefined preprocessor symbol as evaluating to 0. So there is a bunch of #if directives testing the value of PROTOBUF_INLINE_NOT_IN_HEADERS when it hasn’t been defined anywhere; this is legal and should be treated as if it’s a zero.
I fixed this by adding -DPROTOBUF_INLINE_NOT_IN_HEADERS=0 into CCFLAGS in the the top-level SConstruct and CXXFLAGS in src/SConscript (CXXFLAGS) and that seemed to catch it.
So to fix this , you should add this line in the CMakeList.txt that you find in opentxs main folder :
add_definitions(-DPROTOBUF_INLINE_NOT_IN_HEADERS=0)
And don't forget to repeat the cmake step .
Hope this is more clear and helpful .
Fixed this by adding this line at the top of the CMakelists.txt
add_definitions(-DPROTOBUF_INLINE_NOT_IN_HEADERS=0)
