I made hw design on vivado 2019.1 and i build application project on sdk 2019.1 based on .hdf file. (My design consists of microblaze mcs) i have 2 static libraries too .

When i try to compile main() it gives me an error: c:/tmp/sdk/2019.1/gnu/microblaze/nt/bin/../lib/gcc/microblaze-xilinx-elf/8.2.0/../../../../microblaze-xilinx-elf/bin/ld.exe: c:/tmp/sdk/2019.1/gnu/microblaze/nt/bin/../lib/gcc/microblaze-xilinx-elf/8.2.0/../../../../microblaze-xilinx-elf/lib/le/crtinit.o: in function _crtinit': (.text+0x78): undefined reference to main'

Would be happy for some help in that direction

i tried read similar questions and i expect to understand the concept of linker, compiling etc.
