Oliver Smith 1d19c8e21e asn1tostruct: fix defines getting redefined
Do not write the same define twice for two files in a struct, e.g.:

  #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

osmo-iuh - Osmocom Iuh implementation

This repository contains a C-language implementation of the 3GPP Iuh interface. You can use it to interface Iuh-speaking femtocells/small cells to Iu-speaking MSCs and SGSNs.

It is part of the Osmocom Open Source Mobile Communications project.

Homepage

The official homepage of the project is https://osmocom.org/projects/osmohnbgw/wiki

GIT Repository

You can clone from the official libosmocore.git repository using

git clone https://gitea.osmocom.org/cellular-infrastructure/osmo-iuh

There is a web interface at https://gitea.osmocom.org/cellular-infrastructure/osmo-iuh

Documentation

There is currently no documentation beyond the wiki available on the homepage. We would love to see somebody contributing a manual that can be part of the osmo-gsm-manuals suite.

Mailing List

Discussions related to osmo-iuh are happening on the openbsc@lists.osmocom.org mailing list, please see https://lists.osmocom.org/mailman/listinfo/openbsc for subscription options and the list archive.

Please observe the Osmocom Mailing List Rules when posting.

Contributing

Our coding standards are described at https://osmocom.org/projects/cellular-infrastructure/wiki/Coding_standards

We us a gerrit based patch submission/review process for managing contributions. Please see https://osmocom.org/projects/cellular-infrastructure/wiki/Gerrit for more details

The current patch queue for osmo-iuh can be seen at https://gerrit.osmocom.org/#/q/project:osmo-iuh+status:open

Building

It is generally best to check the wiki for the most up-to-date build instructions.

As external library dependencies, you will need

To bootstrap the build, in the root directory, run:

autoreconf --install

After that, run the usual

./configure [options]
make
[sudo] make install

Regenerating C code from ASN.1 source

In order to re-generate the C source code from the ASN.1 source, you will need a modified asn1c which has the following features:
