Is there any way to avoid pro*c precompiler?

Question

I’ve been trying to use openSSL on Oracle tuxedo but its pro-c compiler keep making error. People says pro*c pre-compiler can’t handle code in c99 syntax.

I’d like to know how my code can avoid pre-compiler.

According to openssl github issue (https://github.com/openssl/openssl/issues/9778)

“ wrap your code with defines and add it to the proc call. That code path will be disabled for the Oracle preprocessor”

I have no idea how to do that. I tried like this but it doesn’t work. #ifndef precomp_test #define precomp_test #include <openssl/ssl.h> #endif

All I did is only including ssl.h so far. Can anybody tell me how to avoid precompiler?

You should look at PRO*C precompiler option PARSE={FULL | PARTIAL | NONE}. Unless you have a legacy codebase I suggest using PARSE=NONE which means the precompiler will not try to parse the whole C (or C++) code and instead look only at blocks and lines with EXEC SQL directives.
