Function

Vipsguess_libdir

Declaration [src]

const char*
vips_guess_libdir (
  const char* argv0,
  const char* env_name
)

Description [src]

vips_guess_libdir() tries to guess the install directory (usually the configure libdir, or $prefix/lib). You should pass in the value of argv[0] (the name your program was run as) as a clue to help it out, plus the name of the environment variable you let the user override your package install area with (eg. “VIPSHOME”).

On success, vips_guess_libdir() returns the libdir it discovered, and as a side effect, sets the prefix environment variable (if it’s not set).

Don’t free the return string!

::: seealso vips_guess_prefix().
