compatibility for android with ndk toolchain
eventlOwOp opened this issue · comments
problem
when cross compiling zerotier using ndk toolchain (for android)
it satisfied #if defined(__LINUX__) && ( (!defined(__GLIBC__)) || ((__GLIBC__ >= 2) && (__GLIBC_MINOR__ >= 18)) ) on line 2097 and called pthread_setattr_default_np which is not supported in ndk
one.cpp:2097:2: error: use of undeclared identifier 'pthread_setattr_default_np'
pthread_setattr_default_np(&tattr);

make: *** [<builtin>: one.o] Error 1
make: *** Waiting for unfinished jobs....
to reproduce
make ZT_STATIC=1 ZT_DEBUG=0 ZT_SSO_SUPPORTED=0 CC=aarch64-linux-android33-clang CXX=aarch64-linux-android33-clang++ LDFLAGS="-s -L../deps/aarch64" DEFS="-I../deps/include" ( in ubuntu with ndk toolchain, LDFLAGS and DEFS are set to link the natpmpc library built myself )
or
make ZT_STATIC=1 ZT_DEBUG=0 ZT_SSO_SUPPORTED=0 ( in termux after installing natpmpc apt-get install -y natpmpc )
possible solution
change that line into
#if defined(__LINUX__) && ( (!defined(__GLIBC__)) || ((__GLIBC__ >= 2) && (__GLIBC_MINOR__ >= 18)) ) && (!defined(__ANDROID__))
If you're trying to build ZeroTier One for Android there's a lot more that needs to be ripped out and replaced and custom built for the way Android does things. Our Android APK has entirely different packet processing. So this will not work. Going to close this ticket but if you have an issue with the current Android APK please open a ticket for that.
