Best approach here is to move the macros for specifying the year/month/etc. parts from the version header file to the build config file - leaving the other utility macros for e.g. printing the version string, where they are. For "make", this is done by having a little bit of awk parse the version file and pass the results through to the preprocessor for the config generation stage. For "meson", this is done by parsing the version and adding it to the standard dpdk_conf object. In both cases, we need to append a large number - in this case "99", previously 16 in original code - to the version number when we want to do version number comparisons. Without this, the release version e.g. 19.05.0 will compare as less than it's RC's e.g. 19.05.0-rc4. With it, the comparison is correct as "19.05.0.99 > 19.05.0-rc4.99". Signed-off-by: Bruce Richardson Acked-by: Luca Boccassi --- V3: following Thomas review, include appending .99 to version numbers to ensure correct comparison. Make sure the reason for this is properly documented in the code for future reference. Add in "int" casts for numeric values to strip leading zeros e.g. in "05" month. V2: removed extra change to DPDK_VERSION that crept into patch.
