1) Recent R-devel is a bit misleading concerning the R-framework installation:
A new option --enable-R-framework was introduced, but install-Rframework ignores its absence (or --disable-R-framework for that matter) and tries to install the framework anyway in / which fails just after the R itself was copied into /Versions/.... I know, the user is to blame, but still, a simple check and stop (perhaps with a hint to use --enable-R-framework) would be nice.
2) Wrong -install_name:
[EMAIL PROTECTED]: LIBR_LDFLAGS="-dynamiclib -install_name ${R_FRAMEWORK_DIR}/R.framework/Versions/${PACKAGE_VERSION}/Resources/ bin/libR.dylib -compatibility_version ${PACKAGE_VERSION} -current_version ${PACKAGE_VERSION}"
R_FRAMEWORK_DIR specifies the full path including the framework name, at least according to the previous definition:
[EMAIL PROTECTED]:
if test "${want_R_framework}" = yes; then
R_FRAMEWORK_DIR="/Library/Frameworks/R.framework"
else
R_FRAMEWORK_DIR="${want_R_framework}/R.framework"
want_R_framework=yes
fitherefore R.framework should be removed from the path at line 1094
3) Chicken-and-egg problem:
There is a chicken-and-egg problem if --enable-R-framework is used:
gcc -bundle -flat_namespace -undefined suppress -L/usr/local/lib -o R_X11.so dataentry.lo devX11.lo rotated.lo rbitmap.lo -lSM -lICE -L/usr/X11R6/lib -lX11 -framework R -lz -lreadline -lcc_dynamic -lncurses -lm
ld: can't locate framework for: -framework R
make[4]: *** [R_X11.so] Error 1
--enable-framework adds: LIBR="-framework R" [EMAIL PROTECTED] which is then used:
src/modules/X11/[EMAIL PROTECTED]: R_X11_la_LIBADD = $(ALL_X_LIBS) $(BITMAP_LIBS) $(LIBR)
If you installed R.framework previously, you're fine (well, fine in a sense that R is not compiled against its own version of the shared library as one would expect, but the currently installed R framework instead). If you have a clean system, it won't even build.
It is a touchy subject: during the compilation of R we cannot use the framework as-is, since there is none. On the other hand once installed, we want all packages to use -framework R.
A partial solution is to "fake" a non-installed framework:
Add following to the Makefile.in conditional for Darwin (probably somewhere around src/main/[EMAIL PROTECTED]):
mkdir $(top_builddir)/bin/R.framework
ln -s ../libR.dylib $(top_builddir)/bin/R.framework/R
and add "-F$(top_builddir)/bin" to the LIBS
The addition of -F.. to LIBS should be temporary during the build of R only - I'm not sure if there is such a mechanism in the current R building process though ... if there isn't we could just add something like $(LIBS_BUILD) or similar to all modules that are built before install ...
A side note: unfortunately gcc doesn't honor DYLD_FRAMEWORK_PATH, so we cannot use that elegant solution :(
4) warnings - aqua module under construction?
I guess the aqua code is currently under construction, because it's probably compiled-in twice (in the libR and in aqua.so):
[...]
ld: warning multiple definitions of symbol _InitAquaIO
aquaconsole.lo definition of _InitAquaIO in section (__TEXT,__text)
/Work/R-builds/osx/r-devel/bin/R.framework/R(aqua.lo) definition of _InitAquaIO
[...many warnings of the same kind follow...]
I didn't invesitgate this further - if this is not intentional then I could have a look ... I suspect that this has something to do with Stefano's attempt to separate Carbon code (aqua+quartz) from the core R so it can be used from an external terminal w/o root privileges.
5) --enable vs. --with:
I have a rather general question about configure options: why use the name --"with"-aqua but --"enable"-R-framework ? I'm just curious: after --with-zlib --with-aqua I somehow expected --with-R-framework, but configure neither warns about an unrecognized option, nor does it take it as --enable-R-framework. Remember that R.framework isn't just a different way to install R/dylib, but in future it will also unlock the Obj-C code contained in the R.framework (hopefully) [i.e. to justify --with in case it is meant for additional stuff whereas --enable just pulls a lever somewhere ...].
