openssl/asn1.h header redefinitions in Storm C 4

[ThoughtCheese72]

Hi all,
When including openssl/asn1.h from AmiSSL 4.6 in a project, the compilation fails with many errors "Identifier... redefined". This is using the Stormc 4 compiler with the target as AmigaOS3. I also have errors using their GCC mode

Is there a fix or workaround for it?

Thanks!

First, ensure you don't have any conflicting includes installed - if regular OpenSSL includes are in the include search path, as well as the AmiSSL variants, this will cause problems.

Also, try including openssl/ossl_typ.h first or including amissl/amissl.h instead of individual includes.

Hi, I used the includes in the same was as the example https.c - I think there were three of them and the first was amissl.h. By experience, I included asn1.h on its' own just to see if there were conflicting definitions. I have not had any other implementation of openSSL before this one and the includes folder contained strictly the "shipped" StormC includes. I think I had to drop an inttypes.h in from a previous project to get to this point.

Hmmm... I've been looking into this, but don't really know what to suggest as I don't have StormC. All I know is that I have the AmiSSL includes working fine with GCC and SAS/C. For SAS/C I think I had to modify or replace sys/types.h with something newer.

Thanks for looking, everyone. I thought Storm was the default platform for Amiga development, but I think it may be fun and profitable to cross-compile in VBCC or give GCC a try. It never occurred to me how different the all of these compilers and pre-processors are with respect to the format and syntax they'll accept.

@ThoughtCheese72 Well, if there is anything I can do to make the AmiSSL includes more compatible with StormC, I'm happy to do so. It's just the the error messages given don't seem to point to the root cause, so it is a little hard to debug without owning it. It could be something as simple as a missing type. I would have thought StormC in GCC mode would be fine with the includes, assuming there are no missing types in the standard StormC includes.
