Question

Suppose there is a C program, which stores its version in a global char* in main.c. Can the buildsystem (gnu make) somehow extract the value of this variable on build time, so that the executable built could have the exact version name as it appears in the program?

What I’d like to achieve is that given the source:

char g_version[] = "Superprogram 1.32 build 1142";

the buildsystem would generate an executable named Superprogram 1.32 build 1142.exe

Answer 1

The shell function allows you to call external applications such as sed that can be used to parse the source for the details required.
