Description

I have a problem generating c code from my swagger specification.

I tried to follow the compilation instructions. The cmake .. command was ok. But when I tried to run the command make I got several errors :

[ 26%] Building C object CMakeFiles/swagger_finanting.dir/model/banking_transaction_dto.c.o
/home/jbwittner/Workspace/openapi/c/model/banking_transaction_dto.c: In function ‘banking_transaction_dto_create’:

make: *** [Makefile:149: all] Error 2

And when i check the code i have :

banking_transaction_dto_t *banking_transaction_dto_create(
    int id,
    banking_account_dto_t *banking_account_dto,
    banking_account_dto_t *linked_banking_account_dto,
    third_dto_t *third_dto,
    category_dto_t *category_dto,
    classification_dto_t *classification_dto,
    char *transaction_date,
    char *amount_date,
    double amount,
    double currency_amount,
    currency_dto_t *currency_dto,
    char *description,
    char *create_timestamp,
    char *update_timestamp,
    int is_conciliate,
    int is_cleared
    ) {
    banking_transaction_dto_t *banking_transaction_dto_local_var = malloc(sizeof(banking_transaction_dto_t));
    if (!banking_transaction_dto_local_var) {
        return NULL;
    }
    banking_transaction_dto_local_var->id = id;
    banking_transaction_dto_local_var->banking_account_dto = banking_account_dto;
    banking_transaction_dto_local_var->linked_banking_account_dto = linked_banking_account_dto;
    banking_transaction_dto_local_var->third_dto = third_dto;
    banking_transaction_dto_local_var->category_dto = category_dto;
    banking_transaction_dto_local_var->classification_dto = classification_dto;
    banking_transaction_dto_local_var->transaction_date = transaction_date;
    banking_transaction_dto_local_var->amount_date = amount_date;
    banking_transaction_dto_local_var->amount = amount;
    banking_transaction_dto_local_var->currency_amount = currency_amount;
    banking_transaction_dto_local_var->currency_dto = currency_dto;
    banking_transaction_dto_local_var->description = description;
    banking_transaction_dto_local_var->create_timestamp = create_timestamp;
    banking_transaction_dto_local_var->update_timestamp = update_timestamp;
    banking_transaction_dto_local_var->transaction_type_enum = transaction_type_enum;
    banking_transaction_dto_local_var->is_conciliate = is_conciliate;
    banking_transaction_dto_local_var->is_cleared = is_cleared;

    return banking_transaction_dto_local_var;
}

I'm not sure but the transaction_type_enum_t *transaction_type_enum is missing ??

Someone can help me ?

openapi-generator version

Version 5.3.0

(i have tried with the package openapi-generator-cli-6.0.0-20211109.082840-24.jar and the bug is still there).

OpenAPI declaration file content or url

My specification is here.
The specification is valid.

Generation Details

I have generate the code with openapi-generator-cli generate -i openapi.yaml -g c -o c

Steps to reproduce

• Generate the code
• Follow the build instructions

Related issues/PRs

Suggest a fix

Start with the linked openapi.yaml and reproduce generation using openapi-generator-cli generate -i openapi.yaml -g c -o c, then build the generated project with CMake and make. Inspect the generated banking_transaction_dto model and constructor around the missing transaction_type_enum; done means the generated C project compiles successfully.
