NDK build errors

[Slick]

I modified my flags to the following and it now works (subject to testing):

Code: Select all

LOCAL_CPPFLAGS := -DDG_USE_THREAD_EMULATION -D_CRT_SECURE_NO_WARNINGS -D_POSIX_VER
LOCAL_CPPFLAGS += -DDG_SCALAR_VECTOR_CLASS
LOCAL_CPPFLAGS += -g -DANDROID -fdata-sections -ffunction-sections -funwind-tables -fstack-protector-strong -no-canonical-prefixes -D_FORTIFY_SOURCE=2 -march=armv7-a -mthumb -Wformat -Werror=format-security   -O0 -fno-limit-debug-info  -fPIC   -fPIC -fpermissive -std=c++11

why don't you try 4.0?
oh I am so sorry, I delete you first question by mistake, I was try to delete my last post about github.

I am trying to do a NDK build from the command line in Windows 10.

I've hit an error and I'm not sure if I need to define something. I noticed that dgVector.h has changed since I last used it some the ifdef might be causing a problem.

Anyway here is my error:

CODE: SELECT ALL

sorry about that.

those seem arm neon instructions are you using that?

[Slick]

No I am not using arm specifically. I just want armv7a and arm64a which I now seem to have along with the x86 x64 but I don't think they are too popular on Android.

I will switch to 4.0. I haven't had much time to program and updating libraries etc has taken a bunch of it.

Next on my list is to try out 4.0.
