Unable to build from node-gyp : cannot use typeid with -fno-rtti / jni.h file not found

[omatrot]

I'm using Djinni in the context of a react native project. My starting point is this repo where Djinni is linked as a submodule. In on macOS High Sierra.

When I run npm install, it tries to build Djinni...

I'm sure that I could find a way to not use -fno-rtti but what about the missing file ? Are these 2 problems related ?

Thanks for your help.

The first problem is a node-gyp related problem. I modified ~/.node-gyp/7.10.1/include/node/common.gypi' in line 367 to set YES instead of NO

'GCC_ENABLE_CPP_RTTI': 'YES', # -fno-rtti

The second problem was solved by creating an environment variable: export CPLUS_INCLUDE_PATH=$(/usr/libexec/java_home)/include:$(/usr/libexec/java_home)/include/darwin/:$(cd "dirname "0"" && pwd)/deps/djinni/support-lib/cpp

There has been additional problems all solved by modifying common.gpyi:

'GCC_ENABLE_CPP_EXCEPTIONS': 'YES',

'OTHER_CFLAGS': [
            '-fno-strict-aliasing',
            '-fobjc-arc'
          ],

All problems solved on macOS Sierra

for Linux build (Ubuntu 16.04): we need to fix several issues at 3 different locations: -in our node-gyp installation: common.gypi line for 'OS in Linux .... use those flags: 'cflags_cc': [ '-frtti','-fexceptions', '-std=gnu++0x' ],
