2021-06-07newlib: Add libstdc++ nano-specific CXXFLAGSStephanos Ioannidis1-0/+3
This commit adds a new config that can be used to specify the target CXXFLAGS specific to the libstdc++ newlib-nano variant. By default, this config is set to specify the `-fno-exceptions` option, which disables C++ exception handling support and greatly reduces the compiled binary size.

2021-04-16newlib-nano: Use run-time calculated paths in top-level nano.specsAlexey Brodkin1-3/+3
In currently generated top-level "nano.specs" we resolve paths during toolchain building and then use those pre-defined full paths once the toolchain got built. That's OK until the toolchain is used right were it was built, otherwise paths used in the top-level "nano.specs" become irrelevant and linker fails to find "nano" libs reverting to non-"nano" libs in the default location.

2021-04-15newlib-nano: Add option to copy libs into targetKumar Gala1-0/+25
Add an option that will install a copy of newlib-nano lib*.a file in the target dir but renamed with a nano.a suffix (eg: libc_nano.a) as some default nano.spec files from newlib expect this setup. Additionally the newlib-nano version of newlib.h will get copied to include/newlib-nano/newlib.h. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

2021-02-19newlib-nano: Create symlinks for nano-suffixed libsAlexey Brodkin1-0/+32
If existing board's .specs are used for linking of a user's application, then instead of normally used libs like libc.a & libstdc++.a might be requested their "nano"-suffixed siblings: libc_nano.a, libstdc++_nano etc. That way: ----------------------------->8--------------------------- %rename link_gcc_c_sequence myboard_link_gcc_c_sequence *myboard_libc: %{!specs=nano.specs:-lc} %{specs=nano.specs:-lc_nano} *link_gcc_c_sequence: %(myboard_link_gcc_c_sequence) --start-group %G %(myboard_libc) --end-group ----------------------------->8--------------------------- Our companion newlib-nano libs are all built optimized for size, so we'd like to use them for linking. But given linker will see "-lc_nano -lstdc++_nano" on its command line non-suffixed libs will be ignored. To solve it we create those "_nano"-suffixed libraries as simple symlinks to existing libs..

2020-12-23libgmp: Fix cross-canadian build for macOSAlexey Brodkin1-0/+9
Currently when building cross-canadian toolchain for macOS the folowing error happens when GCC is configured: |ld: illegal text-relocation to '___gmp_binvert_limb_table' in |... /.build/... /buildtools/complibs-host/lib/libgmp.a(mp_minv_tab.o) from '___gmpn_divexact_1' in |... /.build/... /buildtools/complibs-host/lib/libgmp.a(dive_1.o) |collect2: error: ld returned 1 exit status Apparently this might be solved with GMP configured with "--with-pic", even though we're talking about static library here.

2017-05-25Handle ming32 as a hostAlexey Neyman1-14/+35

2017-02-27Require GNU sedAlexey Neyman1-22/+0
After much struggling with macos (BSD) sed and even getting everything work in crosstool-ng itself, I had to abandon that because some components rely on GNU syntax. Specifically, GNU libc uses '/.../{H;g}' (note absense of the separator after 'g'). So, revert the -r/-E detection and check for sed's being of GNU origin. MacOS people, sorry, but you'd have to install GNU sed. Signed-off-by: Alexey Neyman <stilor@att.net>

2016-12-11Make companion libs static.Alexey Neyman5-35/+26
This follows the trend set by 1*.sh scripts that configure ISL, GMP, MPFR, CLooG, etc. Building with shared libraries presents all kinds of problems: - The shared libraries need to be installed into ${CT_PREFIX_DIR}. - The binaries linked against companion libs need to have proper RPATH, or they're looking for shared libs in .build/${CT_PREFIX}/buildtools/lib. - All libraries must agree as to whether they're built shared, static, or both. Otherwise, gettext tries to link in static libncurses.a into a shared library and fails (since libncurses was compiled without the -fPIC switch and hence contains relocations that cannot be handled in a shared library). So this fixes the current mess. If we decide to re-enable building the companion libs shared, we should probably make this dependent on a separate suboption of CT_STATIC_TOOLCHAIN. Add a config loosely based on one reported in the issue 274. Signed-off-by: Alexey Neyman <stilor@att.net>

debug/gdb: properly link with expat

In that case, CT_GetCustom just creates a symlink to the original. In that case, 'cp -a <path> .' gives an error and 'cp -a <path> <newdir>' creates <newdir> as a symlink (which will then run the build inside the shared directory, .build/src/<package>). Signed-off-by: Alexey Neyman <stilor@att.net>
2016-11-21Partially revert 6f8e89cb5ca061e899bf3feaaf3fecf30d366c3e.Alexey Neyman10-27/+27
The referenced commit replaced 'make' with '${make}' everywhere. This is wrong for at least the utilities that we may build as companion tools (make, libtool): this will always invoke the version detected by configure by supplying the absolute path. In other words, the wrappers in .build/tools/bin are not fallbacks - they are either temporary (in case a respective companion tool is built) or permanent redirectors. This is the reason why the PATH= has .build/*/buildtools/bin at higher precedence than .build/tools/bin; the latter has the versions detected by configure and the former has the versions built as companion tools. Revert the rest of the gang (grep/sed/...) for consistency. After all, we may decide to supply some of them as well (awk, for instance). Signed-off-by: Alexey Neyman <stilor@att.net>
2016-09-10complibs: let mingw-gcc find target companion libsKirill K. Smirnov3-3/+33

2016-01-03libelf: Cygwin fix for UNC pathsRay Donnelly1-0/+7

2016-01-03libiconv: configure with --disable-nlsRay Donnelly1-0/+1
On Windows a build failure can be triggered during the build of the static iconv if a dynamic iconv is already present: There's a circular dependency between libiconv and gettext which (on a system with a dynamic gettext (and thus iconv) installed in the system prefix) causes a failure to build iconv.exe statically if it is built with nls .. .. Which needs gettext .. which depends on libiconv .. so libtool finds a dynamically linked libgettext.la .. and therefore presents ld with the dll import library libiconv.dll.a when linking iconv.exe .. as well as the static libiconv.a that it has just built! .. leading to multiply defined symbols from iconv. Therefore, we build it without nls. If it later turns out that we need it to be built with nls, then I will have to build it in two passes (common practice when bootstrapping GNU/Linux distros, MSYS2 and probably Cygwin and Homebrew).

2016-01-03expat: Tidy up and correct configure flagsRay Donnelly1-9/+24
Build shared builds for host unless CT_STATIC_TOOLCHAIN. In all other situations, build statically, as before. It is necessary that the static/shared-ness of expat matches that of gettext on Cygwin/MinGW-w64 as they can't be linked together if they don't match, so we follow the same logic.
