我正在尝试编译 SVGA 源以构建共享库对象。编译时出现此错误

编辑::是的，补丁有效..但是在编译 svga_helper.ko 模块时编译遇到下一个错误

我认为您想使用更新版本的 svgalib。1.4.3 已经很老了，不再维护。如果我没记错的话，它也需要打补丁才能与较新的编译器一起使用。尝试来自http://svgalib.org/的 1.9.x 版本之一

对于更高版本，如果您收到错误：

error: static declaration of 'round' follows non-static declaration

应用以下补丁：

--- svgalib-1.9.25/utils/gtf/gtfcalc.c
+++ svgalib-1.9.25/utils/gtf/gtfcalc.c
@@ -68,5 +68,5 @@

-static double round(double v) 
+double round(double v) 
 { 
    return floor(v + 0.5); 
 }

编辑：

使用 svga_helper.ko 模块中的最新编译问题，设置 NO_HELPER 变量以禁用构建 svga_helper.ko。config.h 等已从更新的内核中删除。从自述文件：

有一个编译时选项可以返回旧行为，即使用 root 权限访问 /dev/mem，而不是 svgalib 助手。要为此进行编译，请选择 Makefile.cfg 中的 NO_HELPER 选项。
