Hello @chentyjpm I am using android studio 3.3 cmake version 3.10.2.4988404 because of GCC is no longer supported - C++17 - Android Studio I force fully have to change build.gradle file arguments "-DANDROID_TOOLCHAIN=gcc" toarguments "-DANDROID_TOOLCHAIN=clang" even tried arguments "" but getting this down error any help would be great

如果是用AS3.0+编译的话，禁用掉所有的-fopenmp参数，在cmake文件里最后一个target_link_libraries里禁用掉gomp

[yanyubing-wh]

我也和这个一样的问题，把Cmakelist文件中的-fopenmp参数删除了，然后又报错，又把对应参数删除了。在cmake文件里最后一个target_link_libraries里禁用掉gomp，这个也注释掉了。但是最后
