[SOLVED] Pipe file contents in g++ to compile

Pipe file contents in g++ to compile

Is it possible to pipe the contents of a file into g++ to compile a program?

I want to do this because I want to use a file from a database rather than a physical file on a disk. The file contents can be easily retrieved via an API I have made.

For instance, I would like to do something like:

g++ contents_of_file -o executable

Thanks a lot.

Sam.

Solution

Yes, you can pipe to gcc if you specify the language using the -x option;

echo "int main(){}" | gcc -Wall -o testbinary -xc++ -
