2022-02-11Convert tabs to spacesAlexey Neyman2-21/+21
Recent changes introduced a mixture of tabs/spaces that result in broken indentation in multiple places. Signed-off-by: Alexey Neyman <stilor@att.net>
2022-02-11Restrict *-uclibc,* canadians to gettext 0.20Alexey Neyman1-0/+22
Newer gettext is incompatible with uClibc-NG in cross-compilation, see the comment in the code. Signed-off-by: Alexey Neyman <stilor@att.net>
2022-02-11Retire obsoleted milestonesAlexey Neyman2-15/+0
... and the code dependent on them, after the latest wave of obsolete package removals. This concludes the glorious history of the original uClibc (non-NG) with lots of kludges removed. There was a choice here, whether to call the resulting libc "uClibc" or "uClibc-ng". I opted in favor of giving uClibc-ng the recognition it deserves, although it had some ripple effect in the ct-ng code. Signed-off-by: Alexey Neyman <stilor@att.net>
2021-09-19gmp: Support building for targetChris Packham1-2/+30
Allow GMP to be build for the target. This will be needed by the up coming gdb-11. Signed-off-by: Chris Packham <judge.packham@gmail.com>
2021-08-22gnuprumcu: Bump to v0.6.0Dimitar Dimitrov1-5/+4
Changes since v0.5.0: * Add spec files for am64x SoCs. * Require Binutils at least version 2.37. * Require pru-gcc to be installed. * Remove linker scripts. Instead set memory sizes from specs. * Activate --gc-sections linker option by default. * The "--host=pru" configure option must be used instead of "--target=pru.

2021-07-30newlib-nano: Fix nano.spec based on CT_NEWLIB_NANO_INSTALL_IN_TARGETKumar Gala1-1/+28
The spec file was missing replacing various libs like libc, libm, etc with their nano equiv when CT_NEWLIB_NANO_INSTALL_IN_TARGET=y. Update the nano.spec file that is generated to rename libc, libm, etc if CT_NEWLIB_NANO_INSTALL_IN_TARGET=y Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
2021-07-13picolibc: Disable wchar_t use in libstdc++Keith Packard1-0/+1
Picolibc doesn't support wchar_t in stdio, so disable the use of these functions from libstdc++. Signed-off-by: Keith Packard <keithp@keithp.com>
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. See https://github.com/crosstool-ng/crosstool-ng/issues/1491. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
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>

Remove trailing whitespace from generated nano.spec file. 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.

Please install docbook2X and use variable DOCBOOK_TO_MAN to point configure to command docbook2x-man of docbook2X. Or use DOCBOOK_TO_MAN="xmlto man --skip-validation" if you have xmlto around.

2017-05-25Handle ming32 as a hostAlexey Neyman1-14/+35
zlib refuses to run configure with mingw32 host and insists that win32/Makefile.gcc is used instead. This requires a change in this Makefile to support static-only builds. Fixes #694. Signed-off-by: Alexey Neyman <stilor@att.net>
2017-04-02Always build ncurses-for-buildAlexey Neyman1-25/+5
If the build machine lacks tic, we need to build it in the first pass even if host==build: ncurses Makefiles are not smart enough to build 'tic' first and use the just-built tic to compile fallback terminfo. Signed-off-by: Alexey Neyman <stilor@att.net>

2017-03-06Explicitly use gcc for GMPDan McGregor1-0/+3

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>
