遇到问题：

1.src/filename_list.cxx文件的fltk::filename_list函数问题：

错误信息：

filename_list.cxx: In function 'int fltk::filename_list(const char*, dirent64***, int (*)(const dirent64* const*, const dirent64* const*))':

filename_list.cxx:69: error: invalid conversion from 'int (*)(const void*, const void*)' to 'int (*)(const dirent64**, const dirent64**)'

filename_list.cxx:69: error:   initializing argument 4 of 'int scandir64(const char*, dirent64***, int (*)(const dirent64*), int (*)(const dirent64**, const dirent64**))'

make[1]: *** [filename_list.o] 错误 1

解决办法：

修改filename_list.cxx:69行改为：int n = scandir(d, list, 0, (int(*)(const dirent **, const dirent **))sort);

 

2.FD＿ZERO，FD＿SET等函数问题

错误信息：

 

 

cc1plus: warning: include location "/usr/include" is unsafe for cross-compilation

x11/run.cxx: In function 'int fl_wait(float)':

x11/run.cxx:461: error: impossible constraint in 'asm'

x11/run.cxx:462: error: impossible constraint in 'asm'

x11/run.cxx:463: error: impossible constraint in 'asm'

解决办法：

/usr/include/bits/select.h文件用自己交叉编译SDK包当中的include/bits/select.h替换。

 

3.修改makeinclude

 

# flags for C++ compiler:

 OPTIM       = -g  -Wall -Wunused  -fPIC

 #CFLAGS     = $(OPTIM)  -I/usr/include

 CFLAGS      = $(OPTIM)  -I/home/mstar/Obama/SDK/opt/include

 #CXXFLAGS   = $(OPTIM)  -I/usr/include -Wno-non-virtual-dtor

 CXXFLAGS    = $(OPTIM)  -I/home/mstar/Obama/SDK/opt/include -Wno-non-virtual-dtor

# libraries to link with:
