因为要用到webgl的ASTC的图片属性所以要使用2012.2.12 但是导出webgl失败报错信息如下

需要留有空格，不能挨着， https://sourcecodeartisan.com/2021/03/06/invalid-suffix-on-literal.html

解决了吗

Gaobobo-C commented 4 months ago

找到WebGLPlugins/lundump.c 第237行，代码代码改成下面这样就可以了 checkliteral(S, &LUA_SIGNATURE[1], "not a");

报错提示是由于在 "LUA_SIGNATURE + 1" 这一表达式中进行了字符指针和整数的相加操作，这样的操作可能会导致错误，因为这不是合法的操作。这个警告意味着编译器认为您可能意图执行一个不确定的操作。解决这个问题的方法是，您可能需要明确地将 LUA_SIGNATURE 的指针与整数进行相加，然后传递给 checkliteral 函数。这可以通过使用数组索引来实现。
