Using a sysroot to provide the Lucid headers+libraries, +with the sysroot path being within the GCC install tree. Want to use the +Lucid system libstdc++ and headers, which means that I'm not +building/installing libstdc++-v3. + +So, configuring with: + --with-sysroot="$SYSROOT" + --disable-libstdc++-v3 \ + --with-gxx-include-dir="$SYSROOT/usr/include/c++/4.4" \ +(among other options). + +Hoping to support two usage models with this configuration, w.r.t. use of +the sysroot: + +(1) somebody installs the sysroot in the normal location relative to the +GCC install, and relocates the whole bundle (sysroot+GCC). This works +great AFAICT, GCC finds its includes (including the C++ includes) thanks +to the add_standard_paths iprefix handling. + +(2) somebody installs the sysroot in a non-standard location, and uses +--sysroot to try to access it. This works fine for the C headers, but +doesn't work. + +For the C headers, add_standard_paths prepends the sysroot location to +the /usr/include path (since that's what's specified in cppdefault.c for +that path). It doesn't do the same for the C++ include path, though +(again, as specified in cppdefault.c). + +add_standard_paths doesn't attempt to relocate built-in include paths that +start with the compiled-in sysroot location (e.g., the g++ include dir, in +this case). This isn't surprising really: normally you either prepend the +sysroot location or you don't (as specified by cppdefault.c); none of the +built-in paths normally *start* with the sysroot location and need to be +relocated. However, in this odd-ball case of trying to use the C++ headers +from the sysroot, one of the paths *does* need to be relocated in this way. +=========================== +Index: gcc-4_6-branch/gcc/Makefile.in +=================================================================== +--- gcc-4_6-branch.orig/gcc/Makefile.in 2011-12-13 22:52:15.000000000 -0800 ++++ gcc-4_6-branch/gcc/Makefile.in 2011-12-13 22:52:21.933635767 -0800 +@@ -587,6 +587,7 @@ + build_tooldir = $(exec_prefix)/$(target_noncanonical) + # Directory in which the compiler finds target-independent g++ includes. + gcc_gxx_include_dir = @gcc_gxx_include_dir@ ++gcc_gxx_include_dir_add_sysroot = @gcc_gxx_include_dir_add_sysroot@ + # Directory to search for site-specific includes. + local_includedir = $(local_prefix)/include + includedir = $(prefix)/include +@@ -3964,6 +3965,7 @@ + -DGCC_INCLUDE_DIR=\"$(libsubdir)/include\" \ + -DFIXED_INCLUDE_DIR=\"$(libsubdir)/include-fixed\" \ + -DGPLUSPLUS_INCLUDE_DIR=\"$(gcc_gxx_include_dir)\" \ ++ -DGPLUSPLUS_INCLUDE_DIR_ADD_SYSROOT=$(gcc_gxx_include_dir_add_sysroot) \ + -DGPLUSPLUS_TOOL_INCLUDE_DIR=\"$(gcc_gxx_include_dir)/$(target_noncanonical)\" \ + -DGPLUSPLUS_BACKWARD_INCLUDE_DIR=\"$(gcc_gxx_include_dir)/backward\" \ + -DLOCAL_INCLUDE_DIR=\"$(local_includedir)\" \ +Index: gcc-4_6-branch/gcc/configure.ac =================================================================== ---- gcc-4.6.0.orig/gcc/cppdefault.c -+++ gcc-4.6.0/gcc/cppdefault.c -@@ -48,15 +48,15 @@ const struct default_include cpp_include +--- gcc-4_6-branch.orig/gcc/configure.ac 2011-12-13 22:52:15.000000000 -0800 ++++ gcc-4_6-branch/gcc/configure.ac 2011-12-13 22:52:21.937635526 -0800 +@@ -144,6 +144,15 @@ + fi + fi + ++gcc_gxx_include_dir_add_sysroot=0 ++if test "${with_sysroot+set}" = set;
