( https://gerrit.osmocom.org/c/osmo-iuh/+/30088 ) Change subject: asn1tostruct: fix defines getting redefined ...................................................................... asn1tostruct: fix defines getting redefined Patch asn1tostruct.py, so it does not write the same define twice for two fields in a struct, for example: #define ENHANCEDRELOCATIONCOMPLETEREQUESTIES_RANAP_EXTENDEDRNC_ID_PRESENT (1 << 0) #define ENHANCEDRELOCATIONCOMPLETEREQUESTIES_RANAP_EXTENDEDRNC_ID_PRESENT (1 << 1) #define ENHANCEDRELOCATIONCOMPLETEREQUESTIES_RANAP_RAB_SETUPLIST_ENHANCEDRELOCCOMPLETEREQ_PRESENT (1 << 2) typedef struct RANAP_EnhancedRelocationCompleteRequestIEs_s { uint16_t presenceMask; RANAP_IuSignallingConnectionIdentifier_t oldIuSigConId; RANAP_IuSignallingConnectionIdentifier_t iuSigConId; RANAP_GlobalRNC_ID_t relocation_SourceRNC_ID; RANAP_ExtendedRNC_ID_t relocation_SourceExtendedRNC_ID; ///< Optional field RANAP_GlobalRNC_ID_t relocation_TargetRNC_ID; RANAP_ExtendedRNC_ID_t relocation_TargetExtendedRNC_ID; ///< Optional field RANAP_RAB_SetupList_EnhancedRelocCompleteReq_t raB_SetupList_EnhancedRelocCompleteReq; ///< Optional field } RANAP_EnhancedRelocationCompleteRequestIEs_t; The problem is that the type is used and it may not be unique inside a struct. Change the code to use the name of the field if the type is not unique. Keep using the type otherwise so existing code doesn't need to be modified a lot to fix this. Fix for: ../include/osmocom/ranap/ranap_ies_defs.h:514: warning: "RANAP_ENHANCEDRELOCATIONINFORMATIONREQUESTIES_RANAP_IUSIGNALLINGCONNECTIONIDENTIFIER_PRESENT" redefined Change-Id: I2ecae6789899952d1dc5691ab76907abeaa71c12 --- M asn1/utils/asn1tostruct.py 1 file changed, 24 insertions(+), 1 deletion(-) git pull ssh://gerrit.osmocom.org:29418/osmo-iuh refs/changes/88/30088/1 diff --git a/asn1/utils/asn1tostruct.py b/asn1/utils/asn1tostruct.py index 220517d..988f7f3 100755 --- a/asn1/utils/asn1tostruct.py +++ b/asn1/utils/asn1tostruct.py @@ -79,6 +79,29 @@ print("-p [pfx] Prefix all types with given prefix") print("-h Print this help and return") +def getUniqueIENameForDefine(ies, ie): + """ Usually the type of the IE is used for defines.
