[ewg] Build errors while trying to build iw_cxgb3 and iw_cxgb4 drivers together

[Vipul Pandya]

Hi Vlad,

 

I am getting a build failure while building cxgb3 and cxgb4 drivers together. The errors are coming because of wrong inclusion of header files. To be precise it includes cxgb3 header files while trying to compile iw_cxgb4 driver. Due to this I am getting following build failure.

=====

 

cxgb4_l2t_send function is declared in l2t.h file. This l2t.h file is present in both cxgb3 as well as cxgb4 directories. Since in above command cxgb3 path is included first, l2t.h file also gets included from there. If I include cxgb4 path first then this error is not coming.

 

Please suggest how should I go to fix this?

 

Thanks,

Vipul
