Unable to get the header files for windows environment

[Itv1529]

i am trying to setup both the oracle19.3 and postgresql12.19 in windows. while setting up the environment it is lacking of these header files "postgres.h", "oci.h" ,"unistd.h".

help for this.

• if postgres.h is missing, you didn't install the PostgreSQL C headers, or you didn't supply the correct path to the build process
• if oci.h is missing, you didn't install the Oracle software development kit, or you didn't supply the correct path to the build process
• if unistd.h is missing, you don't have a C development environment installed on the machine

Make sure to follow the installation instructions and have all the requirements installed.

Please show me the exact steps you followed from the beginning and provide a literal copy of the error messages you get.

Ok, so we have the error messages and we know that you are using Visual Studio.

So what exactly did you do before you started the build?

Any update here, or shall I close the issue?
