I'm trying to install Mono-develop, but when run configure, I get the following message: *** A new enough version of pkg-config was not found. *** See http://www.freedesktop.org/software/pkgconfig/ checking for mono... /usr/bin/mono checking for mcs... /usr/bin/mcs checking for update-mime-database... no checking for pkg-config... (cached) no configure: error: You need to install pkg-config linux:/home/peter/downloads/mono/monodevelop-0.5 # pkg-config bash: pkg-config: command not found So I installed (as root) what appeared to be the latest version of pkg-config (i.e. 0.9.0). Everything seemed to go OK, but there are no files in the default installation directory of /usr/local/bin make insall gives the following output: linux:/home/peter/downloads/pkgconfig/pkgconfig-0.9.0 # make install Making install in glib-1.2.8 make[1]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8' Making install in . make[2]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8' make[3]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8' make[3]: Nothing to be done for `install-exec-am'. make[3]: Nothing to be done for `install-data-am'. make[3]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8' make[2]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8' Making install in gmodule make[2]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/gmodule' make[3]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/gmodule' make[3]: Nothing to be done for `install-exec-am'. make[3]: Nothing to be done for `install-data-am'. make[3]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/gmodule' make[2]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/gmodule' Making install in gthread make[2]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/gthread' make[3]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/gthread' make[3]: Nothing to be done for `install-exec-am'. make[3]: Nothing to be done for `install-data-am'. make[3]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/gthread' make[2]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/gthread' Making install in docs make[2]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/docs' make[3]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/docs' make[3]: Nothing to be done for `install-exec-am'. make[3]: Nothing to be done for `install-data-am'. make[3]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/docs' make[2]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/docs' Making install in tests make[2]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/tests' make[3]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/tests' make[3]: Nothing to be done for `install-exec-am'. make[3]: Nothing to be done for `install-data-am'. make[3]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/tests' make[2]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8/tests' make[1]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0/glib-1.2.8' make[1]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0' make[2]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0' /bin/sh ./mkinstalldirs /usr/local/bin /bin/sh ./libtool --mode=install /usr/bin/install -c pkg-config /usr/local/bin/pkg-config /usr/bin/install -c pkg-config /usr/local/bin/pkg-config make install-man1 make[3]: Entering directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0' /bin/sh ./mkinstalldirs /usr/local/man/man1 /usr/bin/install -c -m 644 ./pkg-config.1 /usr/local/man/man1/pkg-config.1 make[3]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0' /bin/sh ./mkinstalldirs /usr/local/share/aclocal /usr/bin/install -c -m 644 ./pkg.m4 /usr/local/share/aclocal/pkg.m4 make[2]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0' make[1]: Leaving directory `/home/peter/downloads/pkgconfig/pkgconfig-0.9.0' linux:/home/peter/downloads/pkgconfig/pkgconfig-0.9.0 # Trying to install mono develop after installig pkg-config gives the same error.
