[dpdk-dev] compilation error on Suse 11 - LPM init of anon union

Sat, 13 Jan 2018 11:14:53 -0800 

Hi,

There is a new compilation error since this commit in LPM:
        http://dpdk.org/commit/b2e1c99
The brace has been removed because unnecessary with anonymous union.

This union is declared with RTE_STD_C11 for compatibility
with old compilers:
        /** C extension macro for environments lacking C11 features. */
        #if !defined(__STDC_VERSION__) || __STDC_VERSION__ < 201112L
        #define RTE_STD_C11 __extension__                                       
                             
        #else
        #define RTE_STD_C11
        #endif

Unfortunately, it does not work on Suse 11 SP2 with GCC 4.5.1:
        lib/librte_lpm/rte_lpm.c: In function ‘add_depth_big_v20’:
        lib/librte_lpm/rte_lpm.c:886:4: error:
        unknown field ‘group_idx’ specified in initializer

Curiously, the error is exactly the same with ICC 16.0.2:
        http://dpdk.org/ml/archives/test-report/2018-January/038443.html
Is it really using different compilers in those 2 tests?

Someone to check the value of __STDC_VERSION__ with those compilers?
        gcc -dM -E -xc /dev/null | grep STDC_VERSION

Thanks for the help
