A multi-platform C++ library for executable file version reading .
#include <mileversion/mileversion.h>
int main(int argc, char* argv[])
{
mileversion::mileversion version(argv[0]);
if (version.haveInfo())
{
std::cout << "File version: " << version.fileVersion() << std::endl;
}
else
std::cout << "No version info detected" << std::endl;
return 0;
}On Windows, the library reads the VS_FIXEDFILEINFO from the target file.
You must ensure that the file contains it, for example using an .rc file in your source project.
Linux binaries don't have embedded version info like Windows, so a workaround needed to be found.
mileversion reads the binary file using 'libelf' and tries to find a variable with a name in this format:
mileversion_versioninfo_XX_XX_XX_XXthe version info will be the 4 numbers embedded in the variable name.
The macro "MILEVERSION_DECLARE_VERSION(MH, ML, NH, NL)" can be used to declare a variable with the correct name.
Note that the binary file will depend on libelf to run.
