Hi, I am compiling the source from git. There are definitions of macros in include/asm/io.h for the following: mem_inb mem_outb mem_inl mem_outl ... ... The issue is that the driver : drivers/char/ipmi/ - have redeclared these macros as functions statically, in the file - ipmi_si_intf.c I do not know if this driver is used on MIPS at all, but it does get into the way of proper compilation. If compilation of the IPMI driver in any form is disabled (by default it gets compiled as a module), then the compilation goes on smoothly. I changed the names of these functions slightly and made other modifications as to compile properly and now everything is OK, but I do not know if this is the best way to do it, though it works for me now. What is the best solution for this issue? --shuveb
