Sto cercando di cross-compilazione Freetype 2.5.3, così ho potuto usarlo con il mio progetto Android NDK OpenGL ES 2, ma non sono sicuro come farlo. Sto usando Cygwin su Windows. Ho già cercato e letto molte cose a riguardo, ma ho ancora bisogno di aiuto.cross-compilazione Freetype 2.5.3 per Android
ho esportato alcune bandiere in Cygwin:
$ export NDK_TOOLCHAIN=/cygdrive/d/Development/Android/ndk-standalone-15
$ export PATH="$NDK_TOOLCHAIN/bin/:$PATH"
$ export HOST=arm-linux-androideabi
$ export CC=$HOST-gcc
$ export CXX=$HOST-g++
$ export AR=$HOST-ar
$ export LD=$HOST-ld
$ export AS=$HOST-as
$ export NM=$HOST-nm
$ export STRIP=$HOST-strip
$ export RANLIB=$HOST-ranlib
$ export OBJDUMP=$HOST-objdump
$ export CPPFLAGS="--sysroot=$NDK_TOOLCHAIN/sysroot -I$NDK_TOOLCHAIN/sysroot/usr/include -I$NDK_TOOLCHAIN/include"
$ export LDFLAGS="-L$NDK_TOOLCHAIN/sysroot/usr/lib -L$NDK_TOOLCHAIN/lib"
E poi ho cercato di cross-compilazione freetype:
$ ./configure --with-sysroot=/cygdrive/d/Development/Android/ndk-standalone-15/sysroot --host=$HOST --prefix=/ft2tmp --build=$BUILD --without-zlib --with-png=no
ma ho ottenuto un errore:
FreeType build system -- automatic system detection
The following settings are used:
platform unix compiler
arm-linux-androideabi-gcc configuration directory ./builds/unix configuration rules ./builds/unix/unix.mkIf this does not correspond to your system or settings please remove the file `config.mk' from this directory then read the INSTALL file for help.
Otherwise, simply type
make' again to build the library, or
make refdoc' to build the API reference (the latter needs python).cd builds/unix; /bin/sh ./configure '--with-sysroot=/cygdrive/d/Development/Android/ndk-standalone-15/sysroot' '--host=arm-linux-androideabi' '--prefix=/ft2tmp' '--build=' '--without-zlib' '--with-png=no' checking build system type... x86_64-unknown-cygwin checking host system type... arm-unknown-linux-androideabi checking for arm-linux-androideabi-gcc... arm-linux-androideabi-gcc checking whether the C compiler works... no configure: error: in

Alcuni di il file config.log:

Quindi la mia domanda è come dovrei farlo correttamente?
EDIT:
ho usato non impostato su CPPFLAGS e LDFLAGS e utilizzati ./configure con --with-sysroot bandiera, e ora sta facendo bene. problema successivo è che quando uso
make
ottengo il seguente errore:

Ci scusiamo per il ritardo di risposta! Il problema era effettivamente con i percorsi, e sono riuscito a compilarlo su Linux con successo. Grazie per i link, ne trovo un po 'da solo, e controllerò anche il resto! – ngspkinga
