3个回答

1.更换编译器版本,2.源文件把-mfloat-abi=hard参数修改成-mfloat-abi=softfp重新编译库

1.右键单击工程->properties->C/C++build->Setting->ARM v7 gcc compiler->Miscellaneous 把-mfloat-abi的值改成softfp;

2........................................................................................->ARM v7 gcc linker->Miscellaneous 把-mfloat-abi的值改成softfp;

3.在工程bsp包里同样把-mfloat-abi的值改成softfp。

huangcd0144
huangcd0144 linux平台而且Makefile设置-mfloat-abi=softfp或hard一样报错
大约 2 年之前 回复

总算遇到能回答的问题了
假设测试程序为 test.c。
硬浮点交叉编译:
arm-linux-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard -o test test.c

Android调用非NDK编译的静态库的问题

Android调用的静态库必须通过NDK编译吗?假如我用MinGW GCC编译了一个很简单的静态库,就一个add函数,有没有办法用NDK将其转化为Android的静态库?通过NDK编译出静态库文件再封装我已经会了,只需要用PREBUILT_STATIC_LIBRARY指令就行,不过NDK好像无法识别GCC编译的静态库。额,本人C/C++ 0基础,很多概念都没不太懂。

配置Linux编译环境时出现arm-linux-gnueabihf-gcc: fatal error: no input files问题

按照步骤 下载好arm-linux-gnueabihf-gcc相关文件,改好环境变量 打开控制台输入 arm按tab也会弹出来了 ![图片说明](https://img-ask.csdn.net/upload/201905/25/1558773677_170541.jpg) 但是打开eclipse写一段代码编译时候又弹出错误 ![图片说明](https://img-ask.csdn.net/upload/201905/25/1558773773_740787.jpg) 然后我到控制台试一下 也是同样的问题 ![图片说明](https://img-ask.csdn.net/upload/201905/25/1558773922_399462.jpg)

ndk在windows下编译问题

现在的ndk已经自带编译环境,可以直接执行ndk-build.cmd进行编译。但是遇到一个问题, 在编译时识别到相对路径时不会转换,如下图: ![图片说明](https://img-ask.csdn.net/upload/201511/02/1446464005_465688.png) 相对路径变得那么长,以至于超过了windows的最大文件长度, 求解决方法

VFP如何调用C#编译的DLL

RT,如题。譬如A.DLL,里面有个类名为Ainfo,类里的方法GetAinfo(参数1,参数2)。VFP怎么调用这方法,还有这DLL存放的位置有什么规则。请大神赐教

如何用VC6编一个联接SQL2000数据库的句柄,并编译成.fll的格式,给VFP9.0调用!

如何用VC6编一个联接SQL2000数据库的句柄,并编译成.fll的格式,给VFP9.0调用,只要求一个简单的实例,大侠高手们,高台贵手一下!

VFP9编译的多线程文件(DLL)的问题

VFP9编译的多线程文件(DLL),能不能独立与程序结全,而不要原来的.PRG文件,如果能相对会保密一些重要的程序,我一旦将生成的它的.PRG程序移开,整个程序一编译,马上就出错了?

为什么我的交叉编译CGO二进制文件不能在Raspberry Pi(Raspbian)上运行?
