Hello
As subject say, building is ok, but some points arise, so asking some
(maybe elementary) question to experts:
Gcc-4.9.4 on PowerMac-G5 OSX-10.5.8, using apple gcc-4.2.1, build fine,
test and install:
Included in gcc source tree the required libraries: gmp-4.3.2,
mpfr-2.4.2, mpc-0.8.1, and isl-0.12.2, cloog-0.18.1 plus libiconv-1.15.
Configured with:
------------------------
export MAC=powerpc-apple-darwin9.8.0
../gcc-4.9.4/configure --prefix=/usr/local/gcc-4.9.4 --disable-nls
--enable-languages=c,c++ --build=$MAC --host=$MAC --target=$MAC
------------------------
With otool i examine the executables and find:
------------------------
$ otool -L /usr/local/gcc-4.9.4/bin/c++
./c++:
/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version
7.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 111.1.7)
------------------------
Same is for all others exec in bin/
[QUESTION]: libiconv included in sourcetree was build, but later ignored
at link time in favor of system libiconv?
Looking more with otools:
------------------------
$ otool -L
/usr/local/gcc-4.9.4/libexec/gcc/powerpc-apple-darwin9.8.0/4.9.4/cc1
/usr/local/gcc-4.9.4/libexec/gcc/powerpc-apple-darwin9.8.0/4.9.4/cc1:
/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version
7.0.0)
/usr/local/lib/libmpfr.1.dylib (compatibility version 3.0.0, current
version 3.0.0)
/usr/local/lib/libgmp.3.dylib (compatibility version 9.0.0, current
version 9.2.0)
/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 111.1.7)
------------------------
[Q]: cc1 was linked with libs of another installations (4.4.1) resident
in usual /usr/local location? and not with included libs?
And searching for new libs {gmp, mpfr, mpc, isl, cloog, libiconv} i do
not find any,
[Q]:where are (supposed to be) installed after they are build with gcc?
i expect to find in /usr/local/gcc-NNN/lib, but apparently gcc-build
process use the libs obj without install them?
------------------------
$ ls /usr/local/gcc-4.9.4/lib
gcc libgcc_s_x86_64.1.dylib libitm.la libstdc++.a
libatomic.1.dylib libgomp.1.dylib libitm.spec libstdc++.a-gdb.py
libatomic.a libgomp.a libssp.0.dylib libstdc++.dylib
libatomic.dylib libgomp.dylib libssp.a libstdc++.la
libatomic.la libgomp.la libssp.dylib libsupc++.a
libgcc_ext.10.4.dylib libgomp.spec libssp.la libsupc++.la
libgcc_ext.10.5.dylib libitm.1.dylib libssp_nonshared.a ppc64
libgcc_s.1.dylib libitm.a libssp_nonshared.la
libgcc_s_ppc64.1.dylib libitm.dylib libstdc++.6.dylib
$ ls /usr/local/gcc-4.9.4/lib/ppc64/
libatomic.1.dylib libgomp.la libssp.0.dylib libstdc++.a
libatomic.a libgomp.spec libssp.a libstdc++.a-gdb.py
libatomic.dylib libitm.1.dylib libssp.dylib libstdc++.dylib
libatomic.la libitm.a libssp.la libstdc++.la
libgomp.1.dylib libitm.dylib libssp_nonshared.a libsupc++.a
libgomp.a libitm.la libssp_nonshared.la libsupc++.la
libgomp.dylib libitm.spec libstdc++.6.dylib
------------------------
[Q]: Seems that building will use available libs if found, even if are
newest in source-tree?
[big(ger)-Q]: Otherwise stated, how to build gcc (not static) with all
libs i included, in the single gcc own directory? so the whole can be
moved without breaking dependencies, and installed witout overwriting an
older installation?
Thanks for the attention, and in advance for any idea.
Greetings
