Hi to all, because octave can't install symbolic package, I have tried to install ginac on powermac G4 v. 10.4.10. The ginac configure script ends with: checking for pkg-config... /sw/bin/pkg-config checking pkg-config is at least version 0.9.0... yes checking for CLN... configure: error: Package requirements (cln >= 1.1.6) were not met. Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively you may set the CLN_CFLAGS and CLN_LIBS environment variables to avoid the need to call pkg-config. See the pkg-config man page for more details. ________________________ I have no experience with pkg-config, so I decided to use environments variables bash shell: declare -x CLN_CFLAGS="-I/usr/local/include/cln" declare -x CLN_ LIBS="-L/usr/local/libs/ -lcln" for installed cln 1.1.13 which is definitely greater (newer) as 1.1.6. However, this does not work. Can anyone tell to me, how to set the variables above. Or can anyone give a pkg file to handle this problem? Sincerely, Hans-Jürgen Greif
