Hello,
My objective is to build a shared dpdk library on a build machine and copy it
over to target machine of similar hardware specs.
I am building with steps below:
1. untar dpdk source.
2. modify config/common_base as =>
CONFIG_RTE_BUILD_SHARED_LIB=y
CONFIG_RTE_MACHINE=“default”
3. make config T=x86_64-native-linuxapp-gcc export
4. make install T=x86_64-native-linuxapp-gcc export
Looks like step 2 is successful in changing the build to shared-library but
there is no effect of setting CONFIG_RTE_MACHINE=“default”. I see no change in
any of the header files or resultant binary files.
What am I missing?
Thanks
Chai.

Hi Chai,
By "native" machine you can have the problem you mentioned but "default" should
solve the issue.
- Are you sure you are not overwriting your change in config, how do you set it?
- Is there any specific module/part of DPDK you are getting this error?
