font.glyphs[1] = glyph_1;
编译时出现以下错误：

我也尝试了 "glyphs[2]" 和 "glyphs[]" 的各种组合，但都没有成功。我不知道这两个错误是什么意思。任何帮助将不胜感激。
您在初始化时使用了无效语法 font:
font_t font = {
.height = 48,
.glyphs[] = {glyph_0, glyph_1}
// ^^ ---- here
};
已知字段glyphs是一个数组，所以不需要下标运算符。
但是，即使您这样做了，仍然会出现错误，因为 font 定义了一个文件范围，并且您用于初始化的值包含其他变量名称而不是常量。
分配每个字段的语法有效，但仅在函数内有效。赋值是一个可执行语句，不能存在于函数之外。
在文件范围内定义变量而不初始化，然后在main中设置字段：
font_t font;
int main()
{
font.height = 48;
font.glyphs[0] = glyph_0;
font.glyphs[1] = glyph_1;
printf("\n");
...
你的另一个答案解释了你的方法中的语法和语义问题；请不要接受这个。我只想补充一点，只要您愿意使用文字，您 可以 在文件范围内执行初始化。这对我来说似乎是合理的，因为我不明白为什么要像原始代码尝试那样复制字形数据。它可能看起来像这样：
font_t font = {
.height = 48,
.glyphs = {
{ .width = 17, .length = 782, .data = glyph_0_data },
{ .width = 24, .length = 1104, .data = glyph_1_data }
}
};
我正在尝试创建一个包含结构数组的结构。
我的代码到此为止（削减到只有两个字形）

编译时出现如下错误：

我也试过：
font_t font;
font.height = 48;
font.glyphs[0] = glyph_0;
font.glyphs[1] = glyph_1;
编译时出现以下错误：
gcc -o test font2.c
font2.c:132:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘.’ token
font.height = 48;

font.glyphs[1] = glyph_1;
我也尝试了 "glyphs[2]" 和 "glyphs[]" 的各种组合，但都没有成功。我不知道这两个错误是什么意思。任何帮助将不胜感激。
您在初始化时使用了无效语法 font:
font_t font = {
.height = 48,
.glyphs[] = {glyph_0, glyph_1}
// ^^ ---- here
};
已知字段glyphs是一个数组，所以不需要下标运算符。
但是，即使您这样做了，仍然会出现错误，因为 font 定义了一个文件范围，并且您用于初始化的值包含其他变量名称而不是常量。
分配每个字段的语法有效，但仅在函数内有效。赋值是一个可执行语句，不能存在于函数之外。
在文件范围内定义变量而不初始化，然后在main中设置字段：
font_t font;
int main()
{
font.height = 48;
font.glyphs[0] = glyph_0;
font.glyphs[1] = glyph_1;
printf("\n");
...
你的另一个答案解释了你的方法中的语法和语义问题；请不要接受这个。我只想补充一点，只要您愿意使用文字，您 可以 在文件范围内执行初始化。这对我来说似乎是合理的，因为我不明白为什么要像原始代码尝试那样复制字形数据。它可能看起来像这样：
font_t font = {
.height = 48,
.glyphs = {
{ .width = 17, .length = 782, .data = glyph_0_data },
{ .width = 24, .length = 1104, .data = glyph_1_data }
}
};
