- configure: error: Package requirements (ogg >= 1.3 opus >= 1.0.1) were not met:
- No package 'opus' found
- Consider adjusting the PKG_CONFIG_PATH environment variable if you
- installed software in a non-standard prefix.
- Alternatively, you may set the environment variables DEPS_CFLAGS
- and DEPS_LIBS to avoid the need to call pkg-config.
- See the pkg-config man page for more details.
- yeti@ubuntu:~/Downloads/opusfile-0.9$
- So I checked the man page for pkg-config:
- Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
- LT_SYS_LIBRARY_PATH
- User-defined run-time library search path.
- PKG_CONFIG path to pkg-config utility
- PKG_CONFIG_PATH
- directories to add to pkg-config's search path
- PKG_CONFIG_LIBDIR
- path overriding pkg-config's built-in search path
- URL_DEPS_CFLAGS
- C compiler flags for URL_DEPS, overriding pkg-config
- URL_DEPS_LIBS
- linker flags for URL_DEPS, overriding pkg-config
- DEPS_CFLAGS C compiler flags for DEPS, overriding pkg-config
- DEPS_LIBS linker flags for DEPS, overriding pkg-config
- Use these variables to override the choices made by `configure' or to help
- it to find libraries and programs with nonstandard names/locations.
- Not sure where to point deps_libs or url_deps_libs so opus can compile.
