FreeImage编译arm组件
1、 Linux使用的是Makefile.gnu
2、对于make中的这种错误
Source/LibRawLite/./internal/dcraw_common.cpp:2501:3: error: narrowing conversion of ‘-3’ from ‘int’ to char’ inside { } [-Wnarrowing]
在编译文件中添加：
3、 对于整数转转换的错误
dcraw_common.cpp:4546:3: 错误：在 {} 内将‘128’从‘int’转换为较窄的类型‘signed char’ [-Wnarrowing]将文件中这部分代码进行修改：

4 对于这个错误
Source/LibRawLite/./internal/dcraw_common.cpp:6940:97: error: call of overloaded ‘powf64(int, int)’ is ambiguous
10*(table_buf[iLensData+9]>>2) * powf64(4, (table_buf[iLensData+9] & 0x03)-2);
修改对应位置：4改成4.f
if (table_buf[iLensData+9] && (fabs(imgdata.lens.makernotes.CurFocal) < 0.1f)) imgdata.lens.makernotes.CurFocal = 10*(table_buf[iLensData+9]>>2) * powf64(4.f, (table_buf[iLensData+9] & 0x03)-2);
5 对于错误

修改这个文件的对应位置：dsp.upsampling_mips_dsp_r2.c 将R改成Red

6 fpic的问题
1-5修改后已经没有语法错误但是无法编译输出，提示：

makefile增加fpic选项；原始的makefile是只给X86 加了这个选项；下边是完成的makefile.gnu用于arm的：
