ASN1C 7.4.1 was released on April 30, 2020. Changes in this release include the following:
- Fixed an error in which generated C/C++ code would not compile if -static specified in certain cases. One known case was for the 3GPP rel 15.7.0 version of RRC protocol. (ASN-10922)
- Fixed an issue in the GUI where ".c" was not changed to ".cpp" if C++ was selected as the language (ASN-10874).
- Fixed an issue that caused host id checking in a C/C++ run-time license key not to work (SALES-6027).
- Fixed some C/C++ code generation issues surrounding BIT STRING and use of the -x64 command line option. The generated code would not compile (ASN-10836).
- Changed the optimization options for non-Windows builds to use -O3 instead of -O2 (ASN-10804).
- Fixed a defect that caused an erroneous "1 error(s) detected" message to be displayed if "asn1c -nousage" was specified.
- Fixed a defect in C/C++ code generation where the generated code would not compile. This would occur for a BIT/OCTET STRING, with a contents constraint, in a CHOICE type (ASN-10799).
ASN1C 7.4.0 was released on January 31, 2020. New features in this release include the following:
- The primary new capability added in this release is the capability to generate Python code. Support for the BER/DER and JER (JSON) encoding rules is now available with more planned to be added later.
- C/C++ run-time libraries compiled with Visual Studio 2019 compilers have been added to all Windows packages.
- Project files created with the ASN1C GUI can now be used as input to the command-line compiler by using the -proj command-line option. It is also possible to use a file of this type directly without the -proj qualifier as long as it have the extension .acproj (the compiler will recognize it as a project file).
