[dpdk-users] Problem building DPDK libraries

[David Aldrich]

Hi

I am trying to build DPDK 16.07.1 on Wind River Linux 8.

'make' fails:

# make
[snip]
  CC rte_spinlock.o
  AR librte_eal.a
  SYMLINK-FILE include/exec-env/rte_interrupts.h
  SYMLINK-FILE include/exec-env/rte_kni_common.h
  SYMLINK-FILE include/exec-env/rte_dom0_common.h
  INSTALL-LIB librte_eal.a
== Build lib/librte_eal/linuxapp/igb_uio
make[6]: *** /lib/modules/4.1.21-rt13-WR8.0.0.10_preempt-rt/build: No such file or directory.  Stop.
/root/dpdk-stable-16.07.1/mk/rte.module.mk:79: recipe for target 'igb_uio.ko' failed

Indeed, that 'build' directory does not exist:

# ls /lib/modules/4.1.21-rt13-WR8.0.0.10_preempt-rt/
kernel         modules.alias.bin  modules.builtin.bin  modules.dep.bin  modules.order    modules.symbols
modules.alias  modules.builtin    modules.dep          modules.devname  modules.softdep  modules.symbols.bin

Please can someone help me with this?

Best regards

David
