Since every attempt to produce a compiler for my NAS that can be used to compile the OpenJDK failed, I decided to create a toolchain on the NAS to compile this stuff. The reason for a separate toolchain is that libraries are needed that are used by the running system. Replacing them is a bad idea. Therefore I set up a native toolchain to compile other programs into the running system. Basically this is the same as the first couple of chapters form the Linux from Scratch (Version 6.5)<\/a> approach, which I used as guidance. The following listing does not<\/strong> produce the desired results but it is never the less a good starting point.<\/p>\n

First pass<\/h1>\n

Binutilities 2.19.1<\/h2>\n

LDFLAGS=\"-L\/opt\/usr\/lib\" ..\/binutils-2.19.1\/configure --target=$LFS_TGT --prefix=$LFS --disable-nls --disable-werror<\/code>
\nThe LDFLAGS is necessary because the libz.so resides in \/opt\/usr\/lib and not in the standard search path \/usr\/lib. Without this library the size of the type off_t (File pointer) cannot be computed.<\/p>\n

GCC 4.4.3<\/h2>\n

To be able to compile the JDK I need a bootstrap JDK compiler. This will be GCJ. But in the first pass the Java extension is not included. I included the packages GMP, MPFR and MPC in the compile process of GCC.
\n..\/gcc-4.4.3\/configure --target=$LFS_TGT --prefix=$LFS --disable-nls --disable-shared --disable-multilib --disable-decimal-float --disable-threads
\n--disable-libmudflap --disable-libssp --disable-libgomp --enable-languages=c<\/code>
\nThe next step is to install the linux headers of the appropriate version. The version can be retrieved by uname -a<\/code><\/p>\n

GLibC 2.10.1<\/h2>\n

..\/glibc-2.10.1\/configure --prefix=$LFS --host=$LFS_TGT --build=$(..\/glibc-2.10.1\/scripts\/config.guess) --disable-profile --enable-add-ons --enable-kernel=2.6.18 --with-headers=$LFS\/include libc_cv_forced_unwind=yes libc_cv_c_cleanup=yes<\/code>
\nAfter that the specs file of the compile has to be adjusted.<\/p>\n

Second run<\/h1>\n

Binutils<\/h2>\n

CC=\"$LFS_TGT-gcc -B$LFS\/lib\/\" \\
\n AR=$LFS_TGT-ar RANLIB=$LFS_TGT-ranlib \\
\n ..\/binutils-2.19.1\/configure --prefix=$LFS \\
\n --disable-nls --with-lib-path=$LFS\/lib<\/code>
\nThe linker must be created with a special linking to the libary directories:
\nmake -C ld LIB_PATH=\/opt\/usr\/lib:\/opt\/lib:\/usr\/lib:\/lib<\/code><\/p>\n

GCC<\/h2>\n

Even though the version used here differes from the LFS script (4.4.1) the same fixtures can be applied.
\nCC=\"$LFS_TGT-gcc -B$LFS\/lib\/\" \\
\n AR=$LFS_TGT-ar RANLIB=$LFS_TGT-ranlib \\
\n ..\/gcc-4.4.3\/configure --prefix=$LFS \\
\n --with-local-prefix=$LFS --enable-clocale=gnu \\
\n --enable-shared --enable-threads=posix \\
\n --enable-__cxa_atexit --enable-languages=c,c++ \\
\n --disable-libstdcxx-pch --disable-multilib \\
\n --disable-bootstrap<\/code>
\nThe configure may fail due to the CC variable (compiler not found). If so replace $LFS_TGT-gcc with the actual path to the corresponding compiler.<\/p>\n

Tcl 8.5.7<\/h2>\n

This package is compiled into the original host system:
\n.\/configure --prefix=\/opt\/usr\/local<\/code><\/p>\n

Expect 5.43.0<\/h2>\n

.\/configure --prefix=\/opt\/usr\/local --with-tcl=\/opt\/usr\/local\/lib \\
\n --with-tclinclude=\/opt\/usr\/local\/include --with-x=no<\/code><\/p>\n

DejaGNU 1.4.4<\/h2>\n

.\/configure --prefix=\/opt\/usr\/local<\/code>
\nThese last three packages were not installed into the toolchain. Therefore I compiled them a second time for the toolchain.<\/p>\n

Ncurses 5.7<\/h2>\n

.\/configure --prefix=$LFS --with-shared \\
\n --without-debug --without-ada --enable-overwrite<\/code><\/p>\n

Bash 4.0<\/h2>\n

.\/configure --prefix=$LFS --without-bash-malloc<\/code><\/p>\n

Bzip 1.0.5<\/h2>\n

This package has no configuration, the prefix parameter is passed to the make install command:
\nmake PREFIX=$LFS install<\/code><\/p>\n

Corutils 7.4<\/h2>\n

.\/configure --prefix=$LFS --enable-install-program=hostname<\/code>
\nThe tests are very excessive and do not run with user root.<\/p>\n

Diffutils 2.8.1<\/h2>\n

.\/configure --prefix=$LFS<\/code><\/p>\n

Findutils 5.19<\/h2>\n

.\/configure --prefix=$LFS<\/code><\/p>\n

Gawk 3.1.7<\/h2>\n

.\/configure --prefix=$LFS<\/code><\/p>\n

Gettext 0.17<\/h2>\n

.\/configure --prefix=$LFS --disable-shared<\/code><\/p>\n

Gzip 1.3.12<\/h2>\n

.\/configure --prefix=$LFS<\/code><\/p>\n

Patch 2.5.9<\/h2>\n

.\/configure --prefix=$LFS<\/code><\/p>\n

Java<\/h1>\n

For the compilation of the JDK i followed the BLFS<\/a> and its acompanign user site<\/a>.
\nAfter patching up the gcc sources:
\nCFLAGS=\"-I\/opt\/include\" ..\/gcc-4.4.3\/configure --prefix=\/opt\/usr\/local\/gcc-4.4.3 --libexecdir=\/opt\/usr\/local\/lib --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu --enable-languages=c,c++,java --disable-bootstrap --with-gmp-include=\/usr\/include --with-gmp-lib=\/usr\/lib<\/code>
\nThe disable bootstrap because of an error<\/a> in building bootstrap with powerpc.<\/p>\n","protected":false},"excerpt":{"rendered":"
