Thanks for your tips. But since i dont have much experience in MSYS/MinGW, i am giving you the commands that i have used. from your weblink i can see that i need to add ACLOCAL_FLAGS and XDG_DATA_DIRS?? if babl/babl.h is not found, then why no error in ./configure? export GIMP_BETA_DIR=/C/gimp-win-beta export DOWNLOADS_DIR=$GIMP_BETA_DIR/downloads export BUILD_DIR=$GIMP_BETA_DIR/build export MSYS_DIR=$BUILD_DIR/msys/1.0 export INSTALL_PREFIX=/opt export PATH=$INSTALL_PREFIX/bin:$PATH export PKG_CONFIG_PATH=$INSTALL_PREFIX/lib/pkgconfig:$PKG_CONFIG_PATH export LD_LIBRARY_PATH=$INSTALL_PREFIX/bin:$LD_LIBRARY_PATH export CFLAGS=-I$INSTALL_PREFIX/include $CFLAGS export CPPFLAGS=-I$INSTALL_PREFIX/include $CPPFLAGS export LIBS=-L$INSTALL_PREFIX/lib $LIBS mkdir $DOWNLOADS_DIR/src cd $DOWNLOADS_DIR/src wget ftp://ftp.gimp.org/pub/babl/0.1/babl-0.1.2.tar.bz2 mkdir ~/stable-sources tar -xf $DOWNLOADS_DIR/src/babl-0.1.2.tar.bz2 -C ~/stable-sources cd ~/stable-sources/babl-0.1.2 ./configure --prefix=$INSTALL_PREFIX -C make -j4 make install -j4 cd $DOWNLOADS_DIR/src wget ftp://ftp.gimp.org/pub/gegl/0.1/gegl-0.1.2.tar.bz2 tar -xf $DOWNLOADS_DIR/src/gegl-0.1.2.tar.bz2 -C ~/stable-sources cd ~/stable-sources/gegl-0.1.2 ./configure --prefix=$INSTALL_PREFIX -C make -j4 make install âj4 _______________________________________________ Gegl-developer mailing list Gegl-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer
