Magnifico Lorenzo...
ti posto esattamente quello che mi scrive... anche dopo aver installato libglib2.0-dev:
root@ubuntu:~/Ermanno/Software/babytrans-0.9.1# ./configure
loading cache ./config.cache
checking for a BSD compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking whether make sets ${MAKE}... yes
checking for working aclocal... missing
checking for working autoconf... missing
checking for working automake... missing
checking for working autoheader... missing
checking for working makeinfo... missing
checking whether to enable maintainer-specific portions of Makefiles... no
checking for gcc... gcc
checking whether the C compiler (gcc ) works... yes
checking whether the C compiler (gcc ) is a cross-compiler... no
checking whether we are using GNU C... yes
checking whether gcc accepts -g... yes
checking for POSIXized ISC... no
checking for c++... c++
checking whether the C++ compiler (c++ ) works... yes
checking whether the C++ compiler (c++ ) is a cross-compiler... no
checking whether we are using GNU C++... yes
checking whether c++ accepts -g... yes
checking how to run the C++ preprocessor... c++ -E
checking if compiler use ISO headers... yes
checking if compiler know namespace keyword... yes
checking how compiler handle std namespace... as expected by a good C++ compiler

checking if C++ library include stringstream... yes
checking for glib-config... /usr/bin/glib-config
checking for GLIB - version >= 1.2.0... yes
checking for gtk-config... no
checking for GTK - version >= 1.2.0... no
*** The gtk-config script installed by GTK could not be found
*** If GTK was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the GTK_CONFIG environment variable to the
*** full path to gtk-config.
configure: error: *** GTK+ >= 1.2.0 not installed - please install first ***
invece il file configure.log scrive...

Grazie per gli aiuti che mi stai dando

Quando avevo la Mandrake mi capito' la stessa cosa poi installate le lib e gcc non ci fu alcun problema.
