使用emscripten编译stockfish 10 wasm时出现内存错误

Question

我在编译过程中遇到了一个内存问题：“致命的:无法应用sbrk-val，因为内存不可展平”(更多信息如下所示)。实际上，我只是想编译Stockfish js Wasm，但是用以下代码替换了原始的Makefile：custom makefile。

我的目标是尽可能多地避免nodejs依赖，这样我就可以在React Native中使用它。

这是控制台输出

有没有人能告诉我为什么会这样？

Answer 1

我发现我需要更改的是:标志-s TOTAL_MEMORY=33554432修复了内存，编译器拒绝了这个过程。
