Hi, Thanks for your answer,but first of all why introducing zlib to cairo configure is specific I mean that I use *.pc file for all of require library such as openglesv2, freetype, fontconfig and etc but for zlib I try to use package config but cairo can't configure it say that need zlib any way with this configuration I configured the cairo (could you please say me what is different between zlib with others?): ./configure --prefix=/home/super/Desktop/cairo/target/opt --host=${CROSS_COMPILE} --enable-egl --enable-glesv2 CFLAGS="-I/home/super/Desktop/cairo/target/usr/include/" LIBS="-L/home/super/Desktop/cairo/target/usr/lib/ -lz" but with make I got these errors : make[4]: Entering directory `/home/super/Desktop/cairo/cairo-1.14.2/test' CC cairo_test_suite-cairo-test-constructors.o CCLD cairo-test-suite /home/super/Desktop/cubie/toolchain/gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux/bin/../lib/gcc/arm-linux-gnueabihf/4.7.3/../../../../arm-linux-gnueabihf/bin/ld: warning: libexpat.so.1, needed by /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so, not found (try using -rpath or -rpath-link) /home/super/Desktop/cubie/toolchain/gcc-linaro-arm-linux-gnueabihf-4.7-2013.04-20130415_linux/bin/../lib/gcc/arm-linux-gnueabihf/4.7.3/../../../../arm-linux-gnueabihf/bin/ld: warning: libUMP.so.3, needed by /home/super/Desktop/cairo/target/usr/lib//libEGL.so, not found (try using -rpath or -rpath-link) /home/super/Desktop/cairo/target/usr/lib//libEGL.so: undefined reference to `ump_close' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_ParserCreate' /home/super/Desktop/cairo/target/usr/lib//libEGL.so: undefined reference to `ump_mapped_pointer_get' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_GetErrorCode' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_SetUserData' /home/super/Desktop/cairo/target/usr/lib//libEGL.so: undefined reference to `ump_secure_id_get' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_SetDoctypeDeclHandler' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_ParseBuffer' /home/super/Desktop/cairo/target/usr/lib//libEGL.so: undefined reference to `ump_mapped_pointer_release' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_GetCurrentLineNumber' /home/super/Desktop/cairo/target/usr/lib//libEGL.so: undefined reference to `ump_reference_add' /home/super/Desktop/cairo/target/usr/lib//libEGL.so: undefined reference to `ump_size_get' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_ErrorString' /home/super/Desktop/cairo/target/usr/lib//libEGL.so: undefined reference to `ump_reference_release' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_ParserFree' /home/super/Desktop/cairo/target/usr/lib//libEGL.so: undefined reference to `ump_open' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_SetElementHandler' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_GetBuffer' /home/super/Desktop/cairo/target/usr/lib//libfontconfig.so: undefined reference to `XML_SetCharacterDataHandler' collect2: error: ld returned 1 exit status make[4]: *** [cairo-test-suite] Error 1 make[4]: Leaving directory `/home/super/Desktop/cairo/cairo-1.14.2/test' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/home/super/Desktop/cairo/cairo-1.14.2/test' make[2]: *** [all] Error 2 make[2]: Leaving directory `/home/super/Desktop/cairo/cairo-1.14.2/test' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/super/Desktop/cairo/cairo-1.14.2' make: *** [all] Error 2 Could you please say me what's wrong I did?
