我一直在尝试将 mruby 设置为在 C 中使用,但我只成功编译了一个简单的“hello world”示例。其他示例无法编译:当我尝试编译https://github.com/mruby/mruby/blob/master/tools/mrbc/mrbc.c时,我得到了这个:
gcc -Iinclude hello.c libmruby_core.a libmruby.a -lm -o hello
hello.c: In function ‘parse_args’:
hello.c:119:24: error: ‘DUMP_DEBUG_INFO’ undeclared (first use in this function)
args->flags |= DUMP_DEBUG_INFO;
^
hello.c:119:24: note: each undeclared identifier is reported only once for each function it appears in
hello.c:122:23: error: ‘DUMP_ENDIAN_BIG’ undeclared (first use in this function)
args->flags = DUMP_ENDIAN_BIG | (args->flags & DUMP_DEBUG_INFO);
^
hello.c:125:23: error: ‘DUMP_ENDIAN_LIL’ undeclared (first use in this function)
args->flags = DUMP_ENDIAN_LIL | (args->flags & DUMP_DEBUG_INFO);
^
hello.c:154:57: error: ‘DUMP_ENDIAN_MASK’ undeclared (first use in this function)
if (args->verbose && args->initname && (args->flags & DUMP_ENDIAN_MASK) == 0) {
当我尝试以他们建议的方式()gcc -Iinclude hello.c lib/libmruby.a -lm -o hello.out
(实际上:在类似的方式。我已经尝试了两种方式。)我明白了:
gcc -Iinclude hello.c libmruby.a -lm -o hellohello.c: In function ‘main’:
hello.c:17:7: error: too few arguments to function ‘mrb_parse_string’
p = mrb_parse_string(mrb, code);

看起来我缺少一些文件或其他东西,但我不确定是什么。我正在使用 mruby 1.1.0。我有 mruby-1.1.0/include,其中包含 mrbconf.h、mruby.h 和 gcc 搜索路径中的文件夹 mruby,以及 LIBRARY_PATH 中的 mruby-1.1.0/build/host/lib(即使在我的示例中)出了什么问题,我只是将它们放在与我正在编译的文件夹相同的文件夹中)。
知道我的安装和/或我的编译方式有什么问题吗?
