3.7-rc-1 Release Causing application failure for compilation

[Prabhakar Lad]

Hi All,

I have updated to 3.7-rc1 kernel version with latest head with
commit-id 43c422eda99b894f18d1cca17bcd2401efaf7bd0
but when I try to cross compile the Application I am getting following errors.

/home/plad/ti/linus/linus/include/linux/types.h:14:26: error:
conflicting types for 'fd_set'
/home/plad/CodeSourcery/Sourcery_G++_Lite/bin/../arm-none-linux-gnueabi/libc/usr/include/sys/select.h:78:5:

I use the codesourcery toolchain for cross compiling the applications
for ARM. The same compiler is used to  build the uImage for ARM, but
when I try building the apps I see this issue. Can any help me out in
fixing this.

It seems that you are including kernel headers directly in your userspace 
code. Don't do that. Types defined in kernel headers conflict with types 
defined in your toolchain's kernel headers. Instead, just use the headers that 
are part of your toolchain, which in turn include kernel headers that your 
toolchain was built with.
